Product Description

is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils.
Stainless steel pipes are divided into seamless pipes and welded pipes according to the production method. Seamless steel pipes can be divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes and extruded pipes. Cold-drawn and cold-rolled are the secondary types of steel pipes. Processing; welded pipe is divided into straight seam welded pipe and spiral welded pipe.
Stainless steel square pipe classification: square pipes are divided into two categories: seamless steel pipes and welded steel pipes (seam pipes). According to the cross-sectional shape, it can be divided into square and rectangular pipes. Round steel pipes are widely used, but there are also some special-shaped steel pipes such as semicircle, hexagon, equilateral triangle and octagon

The raw material such as mother tube, round bar we use is from Chinese biggest and well-known steel mill: Walsin Steel and Yongxing Steel. We have ISO 9001 and CE certificate, and the Third Party Inspection Certificates such as TUV, BV, Lloyd's, SGS, etc, also can be provided according to customers' requirements, Wooden case package which is strong and suitable for sea transportation is our main method to pack the pipes. And the economical packing method such as packed in bundles is also welcomed by some customers. The tolerance control we use is D4/T4 (+/-0.1mm) on both inside and outside Diameter and Wall Thickness, which is much higher than international standard ASTM, DIN. The surface condition is one of our main advantages: in order to meet different requirements for surface condition, we have annealing and pickling surface, bright annealing surface, OD polished surface, OD & ID polished surface etc.
