VALUE ADD |
Polishing | Can polish nearly any stainless steel pipe item to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Stainless steel polished pipes can also be cut to required size. |
Beveling | Can bevel the edges of stainless steel pipe to prepare for welding or other processes. |
Honing & Turning | Can hone pipe and tube, using a precision abrasion process in order to obtain a desired finish or close dimensional tolerance. |
Heatreating & Annealing | Some grades of stainless steel pipe can be heatreated to change the mechanical properties. |
Positive Material Identification (PMI) | Can perform PMI testing in house for most stainless steel grades, or we can work with independent labs to complete PMI in order to meet customer specifications. |
UT Testing | In some cases, UT testing of the stainless steel pipes may be required. We can assist you with this requirement. A312 TP304 TP316L stainless steel square pipe |
