Product Name:321 stainless steel fin tube

Product name: 321 stainless steel fin tube

Material quality: 321

Process size: conventional diameter 19mm, 25mm, 32mm, 38mm spot, according to the requirements to do sizing, the longest can do 30m, according to the application of different, can use cold drawing (annealing, pickling for soft industrial tube) and cold rolling (uniform wall thickness, hard not annealing inside and outside bright, annealing into soft industrial tube) two kinds of process.

Testing: according to customer requirements can do water pressure, ultrasonic, eddy current testing.

Features: stainless steel boiler tube, stainless steel heat exchange tube, stainless steel condensation tube, with high temperature steam resistance, impact corrosion resistance, ammonia corrosion resistance; Anti scaling, not easy to stain, anti oxidation corrosion; Long service life, reduce maintenance time, save costs; Good technology, can be directly changed tube, uniform tube wall, safe and reliable, overall thermal conductivity is better than 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", GB13296-2007 "Seamless stainless steel tubes for boilers and heat exchangers", ASME SA213 "seamless ferritic and austenitic alloy steel tubes for boilers, superheaters and heat exchangers".
