Hydrostatic Testing

HydroSure™ Integrity Test System

Identify leaks before they happen.

INTEGRA Technologies hydrostatic plug test tools are used to identify leaks and structural flaws in field welds. We can perform hydrostatic testing services up to 2,250 psi and can accommodate pipe sizes from 0.75″ to 30″.

INTEGRA Technologies uses a double block and bleed plug to hydrostatically test slip on, socket weld, and weld neck flanges. Using test plugs reduces testing time as less than a gallon of liquid is required to complete the test.

All of INTEGRA Technologies test tools are non-destructive; they do not damage the interior walls of the pipes or pressure vessels.

INTEGRA Technologies integrates the most advanced hydrostatic testing and isolation plugging methods. We offer you the best pipe isolation tool and certified equipment to capture desired specification needs. Some of these tools are:

  • Double Block and Bleed Isolation and Weld Test Plug
  • GripTight Double Block and Bleed Isolation and Weld Test Plug
  • High Lift Flange Weld Test Plug
  • Grip Tight Test Plug

Frequently Asked Questions

Why should I use these tools?

The Hydrostatic Integrity Test System helps install, maintain, and service critical equipment. These tools are specifically designed for pipe isolation to quickly isolate and hydrostatically test weld joints of any welded flange-to-pipe connection, as well as isolating pipe ends during cutting, grinding, and welding operations. These benefits increase worker safety, minimize downtime, and decrease operational costs.

Most vessels, flanges, valves and other various pipe assemblies are tested at the manufacturer’s facility; so why use these tools?

While most components of an assembly are tested at the manufacturer’s facility, the weld (tie-in point) remains untested. As this connects various assemblies under field conditions, it is a critical part of a zero-leak assembly. Furthermore, a leaking flange may require replacement as part of an on-going maintenance program between turnarounds, creating the need to isolate and hydrotest the connecting weld.

Why not follow traditional method of testing welds i.e. filling the entire system with testing medium and pressurizing to a pre-determined value (usually 1 ½ times the working pressure) and maintain that specific pressure for a pre-determined time?

Such a methodology requires extensive man hours to blank and purge the entire assembly. It requires large amounts of medium to perform the test.

Can the hydrostatic weld testing tool be inserted into the open end of a flange, pipe or tube?

Yes, that is the purpose of the tool. It is centered over the weld to be tested and pressurized with relative ease (the tool is light in weight – no cranes or specialized lifting equipment required).

Why and when should the pipe isolation tool be used?

For example: when welding a flange on an existing piping system / pipeline, to isolate and monitor potentially explosive vapors during hot work.

What does DB&B plug mean?

Double Block and Bleed Isolation tools have dual-port design (i.e. two seals with positive pressure barrio isolate the pipe). This safely isolates hot work from any residual upstream gases.

Are these tools safe to use?

Yes, these tools are safe, effective, economic and approved tools for rapid pipe testing / repairs.

How do I select which tool to use for my application?

When using these tools for pipe isolation or weld testing the following information is required:
a. Pipe diameter
b. Pipe schedule (Wall thickness)
c. Testing pressure
d. Testing time
e. Is chart recording required?
f. Any back pressure (when isolating pipe?)
g. Straight length pipe available?
h. Any corrosion or pitting in the pipe?
