Pipe Test Plug

Click here to enlarge image

Expansion Seal Technologies' GripTight PE test plugs slip over pipe ends and are tightened by hand, significantly reducing downtime and lowering installation costs. The plug design permits testing at two times working pressure, and uses line pressure to seal tightly to the pipe's inner diameter for a secure, leak-proof seal. The plugs can be used to test pipe on both hose reels or on sections that have already been installed.

DeZURIK coal burner isolation valves close off pulverized coal burner lines during maintenance shutdowns, providing increased safety by reducing the risk of fires and accidents. To withstand abrasion or corrosion, the valves feature valve bodies and gates of carbon steel or 304 stainless steel. A bronze yoke sleeve provides easy actuation and additional resistance to corrosion and wear. The valves can be equipped with manual or powered actuators, including handwheel, chainwheel, pneumatic cylinder or electric motor.


Ultrasonic Flow Meter

The LEFM CheckPlus is an eight-path transit time ultrasonic flow meter designed to provide complete redundancy, measuring fluid velocity and temperature along eight chordal paths that cross the pipe in two planes. The result is a mass measurement that compensates for distortion or swirl in the flow. The flow meter can be installed anywhere in the plant without any degradation in accuracy. All welded construction preserves the integrity of a welded piping system.

Proper Calibration of Gas Analyzers

Air monitoring equipment, whether ambient or part of a continuous emissions monitoring system (CEMS) needs to be verified using an outside source. Without proper calibration and maintenance every system will eventually start to give unreliable data. Methods of verification vary depending on the method of measurement and what components are being measured. Therefore, while designing a system it is important to include the necessary verification support equipment. This article contains a brief overview of different verification techniques that are unique to common forms of air monitoring.
