Kaysen stainless steel sanitary pipe is manufactured in accordance with ASTM A270 sanitary standards. Our stainless steel sanitary pipe is made from cold rolled stainless steel strip whose chemical elements are specially controlled to enhance weldability. The weld bead is cold-worked to a full finished condition, resulting in a virtually undetectable longitudinal weld. Bright annealing to 1,900°F minimum follows in a controlled atmosphere to preserve maximum structural integrity. The tubes are then mechanically polished to a 180 grit (20 μ-in. Ra maximum) interior and 150 grit (32 μ-in. Ra maximum) exterior finish via kaysen's state-of-the-art process. Stainless Steel Sanitary Pipes are then line-stenciled with OD, wall, ASTM specifications, grade, and heat number. Price and weight is per foot.
About ASTM A270 sanitary tubing
ASTM A 262: Methods of detecting intergranular corrosion for the magnetization coefficient.ASME boiler and pressure vessel`s numbers and other standards.
ASTM A270 Sanitary stainless steel tubing specification
ASTM A270 sanitary (hygienic) stainless steel tubing is the standard specification for the welded seamless, and heavily cold worked welded austenitic and ferritic stainless steel sanitary tubing. It includes the stainless steel tube types in seamless and welded ERW, EFW. ASTM A270 sanitary tubing intended applied in the diary and food industry, bio processing equipment, and having special surface finish.
SURFACE REQUIREMENTS
Surface of rolled products: No need extra polishing or smooth treatment.
Mechanical polished surface: Purchasers according the same numbering abrasive (grinding stuff) to polish the products get the required products` surface.
Electrolytic polishing of the surface: Before this processing, manufacturer could use other ways to polish products.
The maximum average of roughness: Customers could specify the maximum roughness of internal surface, external surface and both surface.
Normally surface treatment: Internal, External, SF4, SF3, etc.

ASTM A270 stainless steel tube size range
ASTM A270 sanitary stainless pipe usually refers to the small pipe diameters, normally from 1/2" to 2 1/2", thickness from 0.049 in (1.24mm) to 0.15 in (3.81mm).
The maximum outer diameter of ASTM A270 tubing is 12 inches (304.8 mm).
ASTM A270 tubing using inch-pound as the standard unit of measure.
Wall thickness tolerance shall not vary more than 12.5%.
