Seamless Tubing

Summerill Tube has developed technological expertise in cold finishing seamless tubing. Our experience in working with difficult metals such as stainless, including precipitation/age hardening steel and nickel alloys and other specialty metals can help you realize substantial cost savings in the processing of your tubular product.

Summerill Tube can develop special processes to meet your OD and/or ID surface requirements, critical dimensional tolerances, specific mechanical properties and even produce a custom shape design rather than the typical round form.
