High Quality Seamless Steel Tube ASTM 304 304L 316 316L 35CrMo 42CrMo Stainless Pipe

Short Description:

The main features of 310 stainless steel pipe are: high temperature resistance, generally used in boilers and automobile exhaust pipes, and other properties are average.

303 stainless steel pipe: By adding a small amount of sulfur and phosphorus, it is easier to cut and process than 304. Other properties are similar to 304 stainless steel seamless pipe.

302 stainless steel pipe: 302 stainless steel rod is widely used in auto parts, aviation, aerospace hardware tools, and chemical industry. The details are as follows: handicrafts, bearings, slip patterns, medical instruments, electrical appliances, etc. Characteristics: 302 stainless steel ball is an austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC≤28, and has good rust and corrosion resistance.

301 stainless steel welded pipe: good ductility, used for formed products. It can also be hardened quickly through mechanical processing and has good weldability. Wear resistance and fatigue strength are better than 304 stainless steel pipe.

Stainless Steel Pipe Surface Finish

In the future, with the development of science and technology, we expect that stainless steel pipes will have more innovative applications and make greater contributions to the development of society.

Performance characteristics and uses of stainless steel pipes of different materials. 304 stainless steel welded pipe: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening phenomenon. Usage: tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry.

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 316 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 pipes, 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 310s 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.
