Materials: 304, 304L, 321, 316, 316L, 310S, 347h, 317L, 2205, 2507, 904L, etc.
Process size: the conventional diameters of 14mm, 19mm, 25mm, 32mm and 38mm are available in stock. The length can be determined as required, and the maximum length can be 30m. According to different applications, two processes can be adopted: cold drawing (annealing and pickling are soft industrial pipes) and cold rolling (uniform wall thickness, no annealing in hard state, bright inside and outside, and soft industrial pipes after annealing).
Testing: according to customer requirements, we can do hydraulic, ultrasonic and eddy current testing.
Product features: stainless steel boiler tube, stainless steel heat exchange tube, stainless steel condenser tube, with high temperature steam resistance, impact corrosion resistance and ammonia corrosion resistance; Anti scaling, not easy to stain, anti-oxidation and corrosion; Long service life, reduce maintenance time and save cost; Good tube installation technology, direct tube replacement, uniform tube wall, safe and reliable, and the overall thermal conductivity is better than that of copper tube; It is an ideal heat exchange product for the transformation of old units and the manufacture of new equipment.
Production standards: GB3087-1999 seamless steel tubes for low and medium pressure boilers, GB5310-1995 seamless steel tubes for high pressure boilers, gb13296-2013 stainless steel seamless tubes for boilers and heat exchangers, and ASME SA213 Seamless Ferritic and austenitic alloy steel tubes for boilers, superheaters and heat exchangers.
