Hardness Testing

Hardness testing steel pipe
to meet your requirements

In order to meet the performance requirements of our client’s specific projects, we offer hardness testing of our steel pipes, whether seamless or ERW. Using a Rockwell hardness tester, we can determine the yield strength of each individual joint of pipe and sort and inventory accordingly. The Rockwell hardness tester utilizes a conical diamond known as a brale and indicates hardness by determining the depth of penetration of the diamond under a known load. We call this “pinging” the pipe. The depth of penetration corresponds to a relative position on a scale which in turn allows us to determine the yield strength of the pipe.

We appreciate the importance of ensuring the strength of our steel products. Upon request, our hardness tests can be:
