* Test Open End Pipes, Pipelines and Tubing
* Flange Testers
* Isolate and Test Pipe Connections

Curtiss Wright 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 Isolation, Pipe Testing and Repairs

Hydro Test plugs for pipe provide safe and effective testing at working pressures up to 15,000 PsiG (1,034 BarG). 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 that offer a fast, safe and simple method for hydrostatic testing. These pumps are ideally suited for use with all EST test plugs or on a standalone basis.

Open End Test Plugs

GRIPTIGHT MAX

GripTight Max Test Plugs for high pressure applications

Patented dual-serrated gripper design for safe and reliable testing at high pressures up to 15,000 PsiG (1,034 BarG). Highly effective for testing high pressure steam systems, high alloy hardened pipe materials, and down hole / well-head piping. Also effective for testing non-metallic materials including Fiberglass Reinforced Plastic (FRP) and Glass Reinforced Epoxy (GRP).

GRIPTIGHT ELBOW
GripTight® Elbow Test Plug

Eliminate welding on end caps! Versatile plug designed for testing long radius elbows without welding. Patented GripTight MAX dual-serrated, self-aligning grippers provide a safe and effective solution for pipe spools and piping systems terminating in long radius elbows.

FLANGE TESTERS AND ISOLATION PLUGS

GRIPTIGHT ISOLATION
Inline Isolation and Flange Tester

Isolate and monitor potentially explosive vapors during hot work, and hydrotest new weld connections with one easy to operate tool. Dual port design creates a positive pressure barrier between the seals – safely isolating hot work from any residual upstream gases. GripTight Isolation Test Plugs integrate a Double Block and Bleed Test Plug with GripTight Grippers, ensuring operational safety, and minimizing the risk of blowout / expulsion due to unexpected upstream pressure in the line..

HIGH LIFT FLANGE TESTER

flange tester

Monitor upstream conditions, isolate and purge the weld area, perform the weld, and hydro test the weld joint with one easy tool. No blind flanging upstream, no vacuum truck for evacuating the line, and no X-raying. Each test requires a minimum amount of water, no need to fill the entire line. You will use less water and minimize your environmental impact

DOUBLE BLOCK AND BLEED

Isolate and monitor potentially explosive vapors during hot work, and hydrotest new weld connection with one easy to use tool. Dual port design creates a positive pressure barrier between the seals – safely isolating hot work from any residual upstream gases. The volume of water required is so small that testing can be accomplished using a simple hand pump. Easily facilitates testing in remote areas of the facility

GRIPTIGHT REVERSE PRESSURE

Axial Flange Tester

Previous flange testers  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
