The method used to hydrotest prefabricated modules or spools can make or break a project. Traditionally welders install weld caps, then the vessel is filled with medium, the weld caps are cut off and the pipe beveled once again.  This is also a prime example of inefficiency in construction practices due to the enormous waste of time required to weld and remove the welding caps and releveling of the pipe.

HPC Industrial has a better solution.  Our Plain-End Test Service utilizes our patented tool that fits on the outside of the pipe and seals the opening, allowing the pipe to be pressurized and tested. Our technologies can even accommodate open-ended systems that end in fittings such as tees, socket-weld fittings, elbows and reducers.

  • Assemblies that end in elbows, tees, reducers and socket weld fittings can also be hydrotested.
  • Lines of the same test pressure can be connected together and tested simultaneously.
  • Works with primed, painted, and finished coat surfaces.

Benefits of the HPC Industrial Plain-End Test Tool over welding caps

The HPC Industrial Plain-End Test Tool eliminates the inefficient use of labor and supplies as well as other possible scenarios that have the capability to cripple a project. In comparison to traditional methods, our service is approximately 1/3 of the cost and 1/3 of the time required to use weld caps to perform the same testing.  The risk of jeopardizing the dimensional accuracy of the finished product is also eliminated.

Benefits of the HPC Industrial Plain-End Test Tool over internal griping plugs

Because our tools fit on the OD of the pipe, there is no damage on the inside walls of the pipe which is common when using plugs. The pronounced scoring caused by an internal gripping plug can lead to premature corrosion and/or erosion as well as introduce stress risers.  Additionally, when using internal plugs, the area occupied by a plug is not subject to the hydrotesting pressure. This conflict is eliminated with the use of the HPC Industrial Plain-End Test Tool.
