Stainless Steel Pipe Surface Finish

Stainless steel is unique among metals because it already possesses many of the desirable properties required of building materials, and its development continues. Existing types are constantly being improved to make stainless steel perform better in traditional applications, and new stainless steels are being developed to meet the stringent requirements of advanced construction applications. Due to increasing productivity and quality improvements, stainless steel has become one of the most cost-effective materials chosen by architects. .

Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, and economical. The thin-walled pipes and the successful development of new, reliable, simple and convenient connection methods have given them more irreplaceable advantages than other pipes. They will be used more and more in engineering. , the use will become more and more popular, and the prospects are promising.

Process of Production

There are various connection methods for stainless steel pipes. Common pipe fitting types include compression type, compression type, union type, push type, push thread type, socket welding type, union flange connection, welding type and welding and traditional connection. Combined derived series connection methods. These connection methods have different application scopes according to their different principles, but most of them are easy to install, strong and reliable. The sealing ring or gasket material used for the connection is mostly made of silicone rubber, nitrile rubber and EPDM rubber that meet national standards, which relieves users from worries.

Packing and Transportation

1. Plastic sheet packaging
During transportation of stainless steel pipes, plastic sheets are often used to package the pipes. This packaging method is beneficial to protect the surface of the stainless steel pipe from wear, scratches and contamination, and also plays a role in moisture-proof, dust-proof and anti-corrosion.
2. Tape packaging
Tape packaging is an affordable, simple and easy way to package stainless steel pipe, usually using clear or white tape. The use of tape packaging can not only protect the surface of the pipeline, but also strengthen the strength of the pipeline and reduce the possibility of displacement or distortion of the pipeline during transportation.
3. Wooden pallet packaging
In the transportation and storage of large stainless steel pipes, wooden pallet packaging is a very practical way. The stainless steel pipes are fixed on the pallet with steel strips, which can provide very good protection and prevent the pipes from being collided, bent, deformed, etc. during transportation.
4. Carton packaging
For some smaller stainless steel pipes, carton packaging is a more common way. The advantage of carton packaging is that it is light and easy to transport. In addition to protecting the surface of the pipe, it can also be convenient for storage and management.
5. Container packaging
For large-scale stainless steel pipe exports, container packaging is a very common way. Container packaging can ensure that pipelines are transported safely and without accidents at sea, and avoid deviations, collisions, etc. during transportation.
