The CARBER Weld Test service utilizes a patented tool designed and manufactured by CARBER. Our innovative tool revolutionizes the way weld hydrotests are performed. Traditionally after a repair, alteration, modification, revamp or tie-in an entire system would be filled with medium and brought to pressure to test a single weld.  The CARBER Weld Test tool does away with this traditional approach and uses a fraction of the medium and significantly reduces the amount of time needed to test a single weld. A 102” weld can be tested with less than one-half gallon of water.

CARBER has tools in all common pipe sizes and schedules.  Less common sizes can be custom manufactured. The CARBER Weld Test tool fits inside the pipe and creates two seals on either side of the weld. After these two seals are established, medium is brought to the specified test pressure in the annulus between the seals. This pressure is then held for the necessary length of time required to hydrotest the new weld.

Another advantage of the CARBER Weld Test Tool is the ability to test a flange that has been welded into place. The Weld Test service tests the integrity of the weld, the heat affected zone of the weld, and the actual flange simultaneously.

The CARBER Weld Test Service utilizes patented technology for a safe, quick and inexpensive way to hydrotest new welds on piping systems.
