For Type 316 and 347 heat treated stainless steel pipes, these stainless steel pipes are often used in applications with high temperatures and corrosive environments. 316 stainless steel is a stainless steel with good corrosion resistance, while 347 stainless steel has higher heat resistance.

These pipes are often used in industries such as chemicals, refining, oil and gas processing, as well as high temperature heat exchangers, furnaces, and other high temperature equipment. When selecting these pipes, factors such as operating temperature, pressure requirements, and corrosive environments need to be considered.

Main Application

Ferritic stainless steel. Contains 12% to 30% chromium. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other types of stainless steel.

Stainless Steel Pipe Surface Finish

Industrial development changes rapidly, and stainless steel pipes also follow industrial development to meet the development needs of various industries. The following are the wide applications of stainless steel round pipes in various industries:

Water supply and drainage pipes, irrigation systems
Water supply and drainage pipeline engineering is for the transportation and distribution industry. Drinking water and collection. Transportation and discharge of industrial wastewater. Domestic sewage and rainwater pipe (channel) system engineering.
Engineering investment accounts for the majority of total engineering investment. Sprinkler irrigation systems are an important part of agricultural water use. The physical and chemical properties of stainless steel water pipes meet the requirements of modern agricultural water treatment.

Process of Production

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 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 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.
