Grade 304 And 321 Heat Exchanger Tube Size 19 And 25 mm OD ASTM
Stainless steel tube flattening test should be performed. Test, the
loading direction and should be in the vertical position, without
heat treatment of stainless steel pipe pressure to two-thirds of
outside diameter, after heat treatment of stainless steel pipe
pressure to 1/3 of the diameter. Flattening no cracks or bend the
Inside and outside of the stainless steel pipe surface should be
smooth, can not have crack, crack, folding, double skin, and other
defects interfere with use. The wrong side, biting the side, bumps
and other defects shall not be greater than the wall thickness
allowable deviation. Weld defect repair is allowed, but the heat
treatment after the delivery of steel pipe repair should also back
to heat treatment.

Industrial stainless steel coil heat exchanger, boiler, petroleum,
chemical, fertilizer, chemical, pharmaceutical, nuclear power, etc.
Fluid with stainless steel coil: drink, beer, milk, water systems,
medical equipment, etc.
The mechanical structure with stainless steel coil: printing and
dyeing, printing, textile machinery, medical equipment, kitchen
equipment, automobile and ship accessories, building and
Stainless steel coil: light made of stainless steel with good
welding will be a reduction of wall, wall reduction from thick to
thin, this process can make the wall thickness uniformity, smooth,
and the effect of wall stretching wall form without weld. According
to the naked eye is seamless tube, but the process decision is
welded pipe. In the process of reduction of wall with bright
annealing, make internal and external wall won't form oxidation
layer, inside and outside the bright and beautiful, this is medical
products need.Need sizing of next working procedure, the big small
craft, determine the diameter, outside diameter tolerance in
general can be plus or minus 0.01 mm.
Our factory is near to raw material market and high-speed way, the
producing cost is low.
Our factory have long history for producing stainless steel
seamless pipe,both producing and testing
machine is advanced and perfect.
Our factory was certificated by BV/ISO/LR/RINA/CCS/GL/ABS/DNV,
which can improve the quality.
We participated in many famous projects with our pipes.
