Product Description

Stainless Steel Pipe & Tube

Stainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it. The thicker the wall thickness of the product, the more economical and practical it is, and the thinner the wall thickness, the higher its processing cost will be.
The process of this product determines its limited performance. Generally, seamless steel pipes have low precision: uneven wall thickness, low brightness inside and outside the tube, high cost of cutting to length, and pits and black spots on the inside and outside are not easy to remove; its detection and Shaping must be handled offline. Therefore, it embodies its superiority in terms of high pressure, high strength, and mechanical structural materials.

Our company has been dedicated to producing stainless steel seamless pipe since 2003, owning complete producing
technology and abundant managing experience.
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 advanced NDT equipments for the tests such as Eddy Current test, Ultrasonic test,
Hydraulic test and so on.
We have ISO 9001 and PED 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.
In order to keep the inside surface of pipe clean and make it free from deburring, our company develops the unique
and special technology --- Sponge Washing with high pressure.
We have complete after-sale service to deal with the problems in time.

Finish Products
Product Application of stainless steel sheet


Stainless steel pipe/tube is widely used in industry, food machinery, mechanical and electrical industry, household appliance industry, home decoration and finishing industry. The development prospect of stainless steel application will be more and more broad, but the development of stainless steel application largely depends on the development of its surface treatment technology.
