Digital Hydrostatic Testing

Digital Hydrostatic Testing WHAT IS HYDROSTATIC TESTING? Traditionally speaking, a hydrostatic test, also known as a “hydro test” or “pressure integrity test” is a leak test performed to test the integrity of a pipe, storage tank, pressure vessel, control components or connections (welded, fused or mechanical) of a vessel that will facilitate or store pressure while in service.  These tests can be performed on anything from a section of pipe, to the flanges on a valve,…

Hydraulic and Pneumatic Torque Calibration

JM Test Systems is now able to repair and calibrate Hydraulic and Pneumatic/Electric torque wrenches in house thanks to our recently acquired AKO Torque Calibration System.    This industry-leading standard uses AKO’s TorqCal PRO Software, a hydraulic pump with precision regulator, pressure transducer measuring input pressure, and torque transducer measuring output torque for accurate, consistent calibrations up to 20,000 ft/lbs.    Proper bolt torque is imperative in many industries…

JM Test: Authorized Service Center for Georg Fischer

JM Test Systems is now an authorized service center for Georg Fischer MSA Electrofusion Processors. Georg Fischer piping systems, popular in gas and water distribution plants and systems, utilize high quality polyethylene systems with a revolutionary jointing system which virtually eliminates leakage for the lifetime of the system.  These electrofusion processors use current at a low voltage through a fitting with a permanently molded internal heating wire…

Valve Leakage Rates & Safety – JM Test Manufacturing

In April of 2022, the Pipeline and Hazardous Materials Safety Administration (PHMSA), a branch of the U.S. Department of Transportation, announced a new rule to help improve pipeline safety, reduce super-polluting methane emissions, and protect the public by requiring the installation of remotely controlled or automatic shut-off valves on new and replaced onshore natural gas, carbon dioxide and other hazardous liquid pipelines. The new requirements will assist in preventing severe human and environmental…

Calibration Expansion: Anemometer Testing

JM Test Systems has once again expanded our calibration capabilities by adding the Flotek 360 low noise benchtop Wind Tunnel by GDJ Inc. to our lab. What is an Anemometer and how is it used? An anemometer is a device which measures wind speed and direction or gas current.   Anemometers are used in many different industries covering a wide range of applications.  They are used in weather…

Why Personal Protective Grounding/Bonding Is Important

After being in the electrical field for 25 years or more one thing continually comes up during discussions with others in the field and during training sessions and that is Personal Protective Grounding/Bonding (PPG/B). It’s remarkable at the electricians who don’t understand it’s purpose. So, let’s have a brief discussion on this matter. First things first! Definitions of PPG/B, Cable connected to de-energized lines and equipment by jumpering and bonding with appropriate clamps, to…
