Stainless steel welded pipe description
Stainless steel welded pipe features:
1、small caliber stainless steel welded pipe is continuous online production, the thicker the wall thickness, the greater the investment of the unit and melting equipment, the less economic and practical it is. The thinner the wall thickness, the lower the input-output ratio.
2、the process of the product determines its advantages and disadvantages. Generally, the welding steel pipe has high precision, uniform wall thickness, high internal surface brightness (steel pipe surface brightness determined by the surface grade of the steel plate), and can be arbitrarily measured. Therefore, it shows its economy and aesthetics in high precision, medium and low pressure fluid applications.
Stainless steel welded pipe Classification
1、According to the weld form is divided into straight seam welded pipe and spiral welded pipe.
2、According to its use, it is divided into general welded pipe, heat exchanger pipe, condenser pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing, metric welded pipe, roller pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welded thin-wall pipe, electric welded special-shaped pipe and spiral welded pipe
Stainless steel welded pipe application
1、(stainless steel welded steel pipe for mechanical structure). Mainly used in machinery, automobile, bicycle, furniture, hotel and restaurant decoration and other mechanical parts and structural parts.
2、(stainless steel welded steel pipe for fluid transfer). Mainly used for conveying low pressure corrosive media.
