What is Timed Test Mode?

 

 

Vaetrix ETG timed test mode

 

Timed Test Mode is a new Main Menu Option added to our firmware which allows the customer to pre-set the period of time they want the gauge to record prior to beginning their test. Prior to the start of their test, the customer will be able to dictate the length of time the gauge will record at any interval between 1 minute and 24 hours. Once Timed Test is set, the gauge will log pressure for the predetermined period of time, then auto shut-off, preventing the customer from having to manually “stop/end” the recording session.  The end result displays the Start Time/Pressure, Leak Rate, and End Time/Pressure all on one screen.

 

Why Did Vaetrix Create Timed Test Mode?

 

Historically, in residential gas service testing, technicians were required to perform pressure integrity tests at the main distribution line as well as at the residential service line itself.  While the main line tests could last 4-8 hours, the service tests at the residence may only last 10 minutes and typically do not require temperature records.  Technicians were manually recording the start pressure, waiting ten minutes, then manually recording the end pressure to document their test for record.  How did they accomplish documenting this test in a quantifiable way with a time stamp? CELL PHONE PICTURES!  They took a picture of the gauge pressure at the start with a time stamp, and then a picture after 10 minutes with the end pressure and a time stamp.  They then uploaded the pictures in their final report for proof.

 

THE PROBLEMS: (1) Remembering to check the gauge at exactly ten-minutes from the start time in order for the test to be valid; (2) No record or proof any leakage between the ten-minute time period unless watching the gauge the entire test.  (3) No recordable record for proof of the test being properly performed, heavy reliance on cell phone pictures, times and word of technician – no data points.

 

Vaetrix Solution and Industry Impact

 

Problem (1) Remembering to check the gauge at exactly ten-minutes from the start time in order for the test to be valid.

 

SOLUTION – Timed Test mode stops the log for you at the EXACT time frame required. This keeps the test time frame valid.

 

Problem (2): No record or proof any leakage between the ten-minute time period unless watching the gauge the entire test.

 

SOLUTION – Timed Test mode displays the leak rate on the screen in real time as well as at the end of the test to ensure there were no significant leak events missed.

 

Problem (3): No recordable record for proof of the test being properly performed, heavy reliance on cell phone pictures, times and word of technician – no data points.

 

SOLUTION – Timed Test records the data points just like any other test log and it can be extracted and viewed in our software for hard proof of test validity.

 

BONUS IMPACT: Timed Test logs/Screen can be easily uploaded into GPS and Scada Systems.  The industry is beginning to require that pressure integrity tests tie directly into GPS tracking systems that monitor the safety/operating standards of that particular section of pipe. These programs store that pipe’s geographic location, integrity test records and distribution/consumption data. By pinpointing these pipes on the system’s grid, they can gather valuable information make informed decisions on how the grid distributes products safely and effectively.

 

Pressure Relief Valve Testing

Vaetrix ETG series

by Jason Dewar, Vaetrix

 

A pressure relief valve (PRV) is a safety device used on pressure vessels, boilers, or integrated in process control systems to prevent damage due to excessive pressure. When a pressure exceeds a preset limit, the valve opens to relieve some of the gas, vapor, liquid, or steam, the pressure then drops to a manageable or normal value. In most scenarios, the valve will reclose or reseat so there is no downtime or interruption in the process. There are several types and classifications of pressure relief valves available in the industry, periodic testing and maintenance is mandatory for most PRV’s found in Oil & Gas, Power Generation, Chemical, and Aerospace. This maintenance and testing may occur in the field or the device may be removed for a complete overhaul in order to meet the ASME or API published codes for pressure relief devices. Proper operation is essential to prevent damage or injury to personnel.


Traditional Testing Method

 

A common approach to testing PRV’s is to install an analog test gauge or several gauges depending on accuracy requirements, apply pressure, and then watch the needle of the gauge to catch setpoint pressure. The technician may repeat the test several times in order to get a true baseline and record the results manually. The results from different technicians may vary and the accuracy of the test is subject to interpretation.


A Better Way to Test with a Vaetrix ETG Series Gauge

 

 

• Use the Min/Max feature to display the maximum, minimum, and live pressure readings simultaneously. The digital display clearly lets you see the maximum value that was reached during the testing process with a sample rate of 4 readings per second. Just press Reset to conduct another test.

 

• Every Vaetrix digital pressure gauge is provided with a NIST Traceable Certificate and Data backing the accuracy statement for peace of mind and confidence in the reading.

 

• One gauge rated at ±0.05% or ±0.1% full scale can replace several analog gauges that may be required depending on the test accuracy or uncertainty. Save time performing tests and reduce overall maintenance costs.

 

• Document the test with a press of a button. All Vaetrix ETG digital pressure gauges come standard with data logging capability to perform this test based on a 100 sample points and unlimited sessions. Just download the software and use any USB to Micro B cable to record the results digitally. The tabulated data with graph can be printed or stored digitally to meet quality assurance requirements.

Pneumatic Pressure Testing – Data Logging with Vaetrix ETG Bluetooth

Vaetrix pressure testing

by Jason Dewar, Vaetrix

 

Pressure testing is the practice of subjecting pipes or pipeline systems to pressure above operating pressure to confirm the integrity of pipes and fittings that make up the system. The concept is to pinpoint any weaknesses before something goes wrong. For most low-pressure gas lines, the preferred test medium is compressed air or nitrogen. For example, a two-inch service main may be tested at around 100 psi for 10 to 15 minutes and must hold steady pressure. Increased regulations now require that all new transmission lines, distribution lines, or service line installations be pressure tested before being placed into service.

Retrieving Pressure Data using the Data Director App

 

Any Vaetrix ETG equipped with the Bluetooth option will work with the Data Director application. Data-logging sessions can be configured, started, and stopped using a phone or tablet. The interface is very easy to use and the gauge clearly indicates LOG on the LCD display.

 

While company policies vary on what type of device is acceptable for testing, one thing is consistent. The results must be recorded and stored in the gas company’s record system. So, whether the technician is using a pressure chart recorder, analog gauge, deadweight tester, or even a digital pressure data logger, they must ensure the results are scanned in and uploaded back in the office. This takes time and can be expensive if the test results are lost, not accepted, or have to be redone. What if there was a faster and more reliable way to view, store, and share test results in the field?

 

Upload the results with one button click. View and rename sessions on the phone, upload results to the phone, or take it a step further and save them to the cloud. The account is free from Google and can be set up for any business or individual Gmail account. Add testing notes using Microsoft Excel or Google Sheets, and create a secure PDF to share the file. Email a copy of the test or share a link to the file. All you need is an internet connection.

 

The Vaetrix ETG can store 64,000 records or 200 sessions in the gauge memory. Each pressure point is recorded with a date/time stamp from a real-time clock within the gauge.  Data is stored until you erase or delete the memory in the gauge. If you prefer to transfer the results using USB, just plug in the cable and download the Data Director software application for your PC.

 

Pick 0.05%, 0.1%, or 0.25% of full-scale accuracy to fit your accuracy requirements. The accuracy is based on a temperature range of 14°F to 122°F and remains constant through the pressure range selected. All ETG units come with a NIST Certificate and Data. The serial number and gauge model information is recorded on every data logging session to ensure traceability.

5 Valuable Tools for Locating “Unlocatable” Gas Lines

Locating Unlocatable products

Accurate gas line locating and mapping is an integral step in the construction and maintenance of polyethylene pipe systems. Most of the time traditional locating techniques are sufficient, but what happens when those methods fail due to absent or faulty tracer wire connections, or from incorrect or non-existent mapping? This can result in a loss of time and money due to unnecessary excavation, or even worse, accidental damage to the system resulting in a gas leak. Thankfully there are numerous products available that can help you accurately locate and map these “unlocateable” gas mains and service lines! With these tools, you’ll be able to easily trace any hard to locate pipelines and ensure future locates go smoothly.

 

Insertable Tracers

Jameson Mainline Tracer

Tracer wire is usually placed along buried PE pipe to assist in locating the system prior to future digs. A signal is transmitted through the wire, and through the use of a locator, allows the pipe to be traced and marked in order to avoid damage during excavation. Unfortunately accidents happen, and oftentimes that wire can be become severed or disconnected, resulting in the pipe path becoming untraceable. That’s where the Jameson Live Gas Main Line Tracer Kit comes in!

 

By tapping into the pipe with an insertion tee, the Main Line Tracer Kit is capable of inserting a rod into the line without blow-by up to 125 psi. The rod’s internal copper wire can then be energized to radiate a signal to the surface for tracing with a proper locator along a continuous path with minimal or no excavation. With up to 600 feet of rod to insert, a good length of pipe can now be located, properly marked, and digging can begin.

 

Directional Entry Tool

Jameson directional entry tool

If you’re looking to tap into the system in order to insert a camera head into the line, or if you just want more control of your insertion, we recommend using the Jameson Directional Entry Tool. Also allowing no blow-by up to 125 psi, the tool’s vertical insertion makes the rod entry easier by facilitating that difficult first bend while also providing a 360° rotation that allows it to be fed in either direction of the pipe. The Directional Entry Tool fits most camera heads 1-3/8” in diameter or smaller and works on PVC, PE, steel and ductile iron mains.

 

Hot-Tapping System

Georg Fischer Central Plastics SurTap system

Whether you’re in need of a one-time, reusable or permanent port for future access, the Georg Fischer Central Plastics Surtap Tapping System and VersaTap Electrofusion Insertion Fittings work in conjunction with the Jameson Directional Entry Tool to provide exactly that. Once installed, these access ports help aid the insertion of the Main Line Tracer, inspection cameras, shut off bags, bladders and butterfly valves, and can also be used as a siphon or purge point.

 

Key-Hole Gas Camera System

Keyhole camera system

If you need to inspect a pipeline’s internal condition or pinpoint a specific segment of damage without excavating the entire area, a Key Hole Gas Camera System can provide those answers. Like the Main Line Tracer, the camera system can be easily inserted with the Directional Entry Tool through GFCP VersaTap fittings, allowing you to easily feed the rugged camera head through the system and internally inspect up to 400 feet of pipe to reveal any damage that needs repairing.

 

Electronic Marking System Technology

Once the pipeline system has been traced and repairs have been made, permanently mark those lines so they can be easily located in the future. This can be accomplished by dropping in an electronic marking system along the pipe path. 3M’s Electronic Marking System (EMS) consists of multiple options dependent on the system’s depth. These range from near-surface markers for a max depth of 2 feet, ball markers for depths down to 5 feet, and full-range markers that can be placed down to 8 feet.

 

RFID models are also available. These can be programmed to include customer-specific information such as facility data, type of application, material type and size, & placement date. Once placed, future locates can be performed quickly and accurately with the use of a 3M EMS locator.

 

Another virtually maintenance free solution for marking and locating the path of underground PE pipe and conduits is 3M’s EMS path marking tape and rope. Both options can be used to provide pinpoint locating accuracy at depths down to 4 feet.

3 Essential Tools for Excavation Safety

Excavating essentials

Among the most hazardous construction operations in the underground utility industry are trenching and excavation. Excavation is defined by OSHA as any man-made trench, cut, depression, or cavity formed by removal of the earth’s surface. A trench is a narrow underground excavation that is deeper than it is wide, and no wider than 15 feet.

 

Cave-ins, falls, and hazardous atmospheres contribute to dozens of injuries and even fatalities each year. Due to these dangers, OSHA requires that companies provide equipment designed to help keep their employees safe when working in trench excavations 4 feet or deeper. At EGW Gas Solutions, we supply a number of products that aid in protecting workers within these precarious environments, including trench shoring, telescoping ladders and intrinsically safe blowers/exhausters.

 

UltraSHORE Aluminum Trench Boxes

Ultrashore trench shoring box

UltraSHORE aluminum trench boxes give workers protection in trenches up to 12 feet deep, even in Class “C” soils (gravel or sand). They are composed of a specially corrugated, puncture proof aluminum that weighs hundreds of pounds less than other shoring products.

 

All UltraSHORE panels can be used horizontally or stacked vertically, arranged as parallel shields or in a “vee” or “wedge” configuration, and each end can be closed off with quick-release, spring-loaded end closure panels. One panel pair can be assembled and lowered by a single person, and two people can lower a stacked assembly of two panels into an excavation. These panels are easily broken-down to fit in even the smallest pickup truck, or placed on one of our custom trailers for transport to and from the job site.

 

UltraSHORE Aluminum Trench Boxes are perfect for municipalities, utility companies, underground contractors and more!

 

Telesteps Telecopic Ladders

Telesteps telescoping ladder

The safe, stable entry and exit of an excavation or trench is critical in limiting falls that can lead to injury or worse. To help with this, we offer 16 and 18 foot reach extension ladders from Telesteps.

 

These professional, wide-step, telescoping ladders are lightweight yet durable due to their Type 1A 300lb rated, aircraft grade aluminum construction. Wide step rungs allow for added safety and maximum grip and the 100% silicone pivoting feet help ensure it won’t slip. These ladders also feature a One-Touch release mechanism that allows for fully automatic up and down operation as well as safety indicator windows to tell you when it’s safe to climb.

 

Telesteps Telescopic Ladders are both OSHA Compliant and ANSI 14.2 tested.

 

Ramfan Intrinsically Safe Blowers/Exhausters

Ramfan blower

Exposure to hazardous gases is another risk that workers face when operating within trenches. Not only are the fumes dangerous to inhale, but the slightest spark can cause a devastating explosion. Proper gas exhaustion is essential before any construction or repair within the trench can be initiated. That’s where the Ramfan Intrinsically Safe Blower/Exhauster comes in.

 

The Ramfan UB20xx 8” explosion-proof blower/exhauster is manufactured to meet the requirements of the ATEX Directive, IEC standard and INMETRO standards. It can safely blow or exhaust hazardous gas with minimal risk of the fan causing a spark. It is built using only explosion-proof components along the electrical path and the whole unit is certified for safe use in combustible atmospheres. Anti-static ducts of various sizes are available to suit numerous settings.

 

This ultra-quiet, durable, compact and lightweight blower/exhauster will provide the user with the peace of mind that comes with knowing that they’re using a certified explosion-proof product!

 

Trench Safety is Always a Priority

No matter how complex the job, any time that utility work is to be done within a trench or excavation, proper equipment is needed to ensure worker safety. EGW Gas Solutions is able to provide the tools discussed as well as hundreds of other products designed to make underground utility operations more efficient and secure.
