Stainless Steel Welded Tube， ASTM A270， ASTM A249 ， EN10217-7 ， 1.4301 1.4307 1.4404 6M
TONG CHUANG's 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 TONG CHUANG's state-of-the-art process. Stainless steel sanitary pipes are then line-stenciled with OD， wall， ASTM specifications， grade， and heat number.
