EST Group offers a complete line of Flange Testers ,Hydrostatic Test and Isolation Plugs for pressure testing of pipe, pipelines and pressure vessels.
Safe, effective solutions for rapid pipe testing and repairs
GripTight Test plugs provide safe and effective testing at working pressures up to 15,000 psi (1034 Bar). Pipe OD and ID sealing versions available.
Flange Testers are designed for quickly isolating and hydrostatically testing weld joints of any welded flange-to-pipe connection as well as isolating pipe ends during cutting, grinding and welding operations.
Also available are hydrostatic test pumps, ideal for use with our entire range of Flange Testers and Pressure Test plugs.
Griptight Max™ Test Plug
• Patent-pending dual-serrated gripper design provides more gripping points on inside pipe surfaces • Test pressures to 15000 PsiG (1030 BarG) • New hardened shaft increases durability, plug life and reduces wear • Stocked sizes for NPS ranging from 1” to 8” (DN25 – DN200), larger sizes up to 24” (DN 600) available on request • Safe and reliable testing at higher pressures • Effective for testing non-metallic pipe such as FRP and GRE • Facilitates testing in accordance with ASME PCC-2 and ASME Boiler and Pressure Vessel Codes • Saves over 90% in testing time vs. welded-on end cap testing procedures.
The GripTight Isolation Plug revolutionizes isolation and flange testing of pipe connections by providing unique safety features. The GripTight Isolation Plug allows an operator to positively isolate and monitor potentially explosive vapors during “hot work”, then effectively hydrotest the new weld connection with one easy to use tool. The GripTight Isolation Plug integrates a Double Block and Bleed Test Plug with GripTight Grippers.
Pressure testing flange-to-pipe welds with EST Group’s GTRP ( Flange Testers) eliminates the need to blind, fill, and pressurize the entire piping system, which in turn eliminates the need to properly handle and dispose of potentially contaminated test fluids. Testing performed with the GTRP is quick, easy, safe and meets the requirements of
