A270-BPE 316L High Purity Stainless Steel Tubing Mechanically polished for pharmaceutical
ASME BPE and ASTM A270 specifications, this high quality tubing is 100% bore-scoped and mechanically polished on both the ID and OD. Finishing processes guarantee specific ID and OD Ra values for customers application, minimizing surface anomalies. Moreover, all A270-BPE series tubing is cleaned in a Class 100 Cleanroom (Fed 209E), significantly reducing customer inspection requirements prior to installation. The finest quality stainless steel materials are made to melt criteria and formed by the manufacturering processes to assure highest weld seam integrity, to meet the most demanding applications. Our tubing is available in 1/2" (12.7 mm) to 6" (152.40 mm) OD in 20ft. (6.1 m) lengths.
SPEZILLA is leading manufacturer & suppliers of stainless steel seamless and welded tubing manufactured as per ASTM A270 standards. It is certified to the requirements of ASTM A270 standards, and most user specifications.
Materials Our sanitary tubing is available in alloys 304/304L and 316/316L. All 316/316L tube is supplied with a sulfur content of .005-.017% as specified in ASTM A270, Supp. S2.1.1. Available in A249, A269 and A270
Surface Polish:
Surface finish is 20 u-in Ra (0.5um) ID maximum, 30 u-in Ra (0.8um) OD maximum surface roughness measured per ASME/ANSI B46.1 with the profilo-meter reading at 90 degree to the lay. Other finishes available upon request.
Available Sizes:
OD from 1/2'' to 8'' (12.7MM to 203.20MM)
Wall thickness: 0.065'' to 0.083'' (1.65MM to 2.11MM)
Length: 20ft ( 6100MM)
Various types of polishing operations are commonly used to reduce the surface roughness of stainless steel sanitary tubes used in fluid piping & related components. As the name implies, mechanical polishing involves the application of physical force on abrasive media to remove the irregularities.
Surface Roughness: Bright Annealed, Mill Finish is available for both ID/OD, Mechanical Polish, Electro Polish needs to specify either ID/OD.
