Product details
Material: 304, 304L, 321, 316, 316L, 310S, 347H, 2205, 250 7, 904L, etc.
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 industr↔ial tube) and cold rolling (uniform wall thickness, hard not annealing insid>e and outside bright, annealing into soft industrial tube) two kinds of process.
Testing: according to customer requirements can do water pressure, ultrasonic, ed≥dy current testing.
Features: stainless steel boiler tube, stainless steel heat exchange tube, stainless steel conde¥nsation tube, with high temperature steam resistance, impact corrosion ♥resistance, ammonia corrosion resistance; Anti scaling, not easy to stain, anti oxidation corro∏sion; Long service life, reduce maintenance time, save costs; ♥Good technology, can be directly changed tube, uniform tub↑e wall, safe and reliable, overall thermal conductivity is better t♠han copper tube; It is an ideal heat exchange product for the transformation of old u∑nits 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"α;, GB13296-2007 "Seamless stainless steel tubes for boilers and heat exchangerΩs", ASME SA213 "seamless ferritic and austenit∏ic alloy steel tubes for boilers, superheaters and heat exchangers".
