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.

Open End Test Plugs

GRIPTIGHT MAX

GripTight Max Test Plugs for high pressure applications

Griptight Max™ Test Plug can test pressures to 15000 PsiG (1030 BarG)  and are designed  for testing Hard Alloy, Carbon Steel, Stainless Steel and non-metallic pipe such as FRP and GRE. The plugs take minutes to install and  speed up hydro-testing scopes significantly.  They save over 90% in testing time vs. welded-on end cap testing procedures.

GRIPTIGHT ELBOW
GripTight® Elbow Test Plug

EST Group’s GripTight® Elbow Test Plug is a revolutionary new plug designed for testing long radius elbows.  It can test up to 231 BarG  and  provides a safe and effective solution for pipe spools and piping systems that terminate in long radius elbows.

 

FLANGE TESTERS AND ISOLATION PLUGS

GRIPTIGHT ISOLATION
The GripTight Isolation and Flange Test plug

The GripTight Isolation Plug revolutionizes isolation and flange testing of pipe connections by providing unique safety features. It 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 Gripper design makes this the safest inline isolation plug on the market.

 

 

HIGH LIFT FLANGE TESTER

flange tester

EST Group’s High Lift Flange Weld Test Plug is a safe, reliable, 4-in-1 tool that enables you to carry out a weld and test it in a quicker and safer time frame. It reduces the amount of water required to carry out a flange weld test significantly. The High Lift Flange Tester lets you monitor conditions upstream of the seal, isolate and purge the weld area, complete the weld and hydro test with one tool.

 

DOUBLE BLOCK AND BLEED

Double Block and Bleed In line isolation and flange test plug

The Double Block and Bleed (DBB) plug enables you 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 aluminum/steel construction makes the tool highly portable, and easy to position. The volume of water required for a test is so small that testing can be accomplished using a hand pump.

 

GRIPTIGHT REVERSE PRESSURE

Axial Flange Tester

Previous flange weld testing devices have been shown to apply only radial and hoop stresses to the weld location. Use of these devices for pressure testing will not adequately test or verify the axial strength of the flange-to-pipe weld.  Testing performed with the GTRP is quick, easy, safe and meets the requirements of ASME/ANSI B16.5

HYDROSTATIC TEST PUMPS

Portable Test Pumps Used For Testing Tubes, Pipes, and Various Pressure Vessels

P-Series

Ideal for hydro testing heat exchanger tubes, pipe and pressure vessels in the field or in the shop. Available in two outputpressures, 2,500 or 10,000 PsiG (172.4 – 689.5 BarG). All wetted parts are stainless steel. It has an easy to read 4” (102 mm) diameter pressure gauge. Completely enclosed in a lockable aluminum
tool box.

P-Series Hand Pump

Hydrostatic TestingHand Pump

A self-contained and portable hand pump for testing tubes, pipes, and pressure vessels. It is integrated into a 5 gallon attached reservoir which is easily refilled. The pump is hand operated, which eliminates the need for compressed air. Available in 3000 PSI and 10 000 PSI models

Blue Max 3

Suitable for all hydrostatic testing applications. Available in a
number of output pressures ranging from 1,000 – 10,000 PsiG
(68.9 – 689.5 BarG). Higher pressures available. Blue Max 3
features include all stainless steel wetted components and an easy
to read 4” diameter (102 mm) pressure gauge. It’s also supplied
with mating quick connect couplings for air inlet, water inlet and
high pressure outlet connections. The enclosed cabinet design
provides a safe and quick operation, and protects components
from damage.
