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
