Grade 304 And 321 Heat Exchanger Tube Size 19 And 25 mm OD ASTM A213
Specifications:
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 lateral fissure.
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.

computational formula:
Commonly used: material 201/304/304L/ (diameter wall thickness) x wall thickness x0.02491x length = weight (kg)
Material 316/316L (diameter wall thickness) x wall thickness x0.02513x length = weight (kg)
Unit: kg/m
Applications:
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 decoration, etc.
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.
Competitive Advantage:
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.
