STERiBORE� ASME BPE HIGH PURITY ASTM A270 316L
STAINLESS STEEL TUBES
STERiBORE�: is ideal for Bioprocessing and Pharmaceutical applications requiring mechanically polished surface finishes to 20 Ra min (0.5 Ra mm) ID maximum and 32 Ra min (0.8Ra mm) OD maximum.
STERiBORE�: Tubes exceed the requirements of the ASME BPE 2002 specification on dimensions and tolerances and fully meet the ASME BPE-2002 specification for OD and ID surface finishes
STERiBORE�: Tubes are marked with specification, size, grade and heat number and ASME BPE surface finish designation. Tubes are supplied in 20ft / 6M lengths with ends prepared for orbital welding and capped. STERiBORE� tubing is available from stock with ID cleaned for oxygen service.
STERiBORE�: Other ID cleaning procedures are available including thermocouple cleaning per ASTM A632 or Nitric Acid & DI Water Rinse. The DI water systems used guarantees 50 PPB with an average of 10 PPB and a restivity of 17.98 to 18.03. Ultra High Purity 99.9999% pure Nitrogen is also utilized which is filtered to 0.003 micron at the point of use. Cleaning and packaging is performed in a Class 100 clean room.

Mechanical Tests: Full mechanical testing is conducted according to ASME SA249 and ASTM A270/ A249/ A450. This includes reverse bends, flattening and flange testing, eddy current (non-destructive) electric testing. All material is 100% bore-scoped inspected prior to mechanical polishing. Hydrostatic and other tests available on request.
