304 Stainless Steel Seamless Tubes
Stainless steel seamless tube is a kind of long steel with hollow section. Its diameter is from 20cm to 200mm and thickness from 0.5cm to 50.0mm,As we know, boiler tube is a high-quality carbon structural steel, boiler material, the carbon content of less then 0.24%.
However, 304 Stainless Steel Seamless Tubes is more economical and practical. If sort of from technology, it has hot rolled stainless steel seamless tube, hot extruded stainless steel seamless tube and cold drawn stainless steel seamless tube. 20G is the steel material of GB 5310- 2008. GB 5310- 2008 standard is applicable to seamless tubes for making steam boiler whose pressure is high or higher and seamless tubes used as pipelines.
304 Stainless Steel Seamless Tubes is seamless according to the naked eye, but the process is decided. With bright annealing process by pipe wall in the outer and inner walls will not form an oxide layer, this is really needed for medical products.
The Usages:
1)Industrial stainless steel coil pipe: heat exchanger, boiler, chemical fertilizer, chemical fiber, nuclear power and so on.
2)Mechanical Structure Stainless Steel Coil pipe: printing and dyeing, printing, textile machinery, kitchen equipment, automobile and medical equipment, and decoration, etc.
3)Liquid stainless steel pipe: beer, mikl, water, sauce, medical industry.
Inspection and Test:
Chemical Composition Inspection, Surface and Dimension Test, Weight test, Mechanical Properties Test, No-destructive Test, Hydrostatic Test.
The process of the product determines its limited performance, generally the precision of stainless steel seamless tube is low: uneven wall thickness, low surface brightness inside and outside the tube, high fixed-size cost, high temperature steam, impact corrosion, resistance to ammonia corrosion.
