Main Application

310 stainless steel welded pipe: The main feature is high temperature resistance. It is generally used in boilers and automobile exhaust pipes. Other performance is average.

1. 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.

2. Austenitic stainless steel. It contains more than 18% chromium, and also contains about 8% nickel and a small amount of molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can withstand corrosion from various media.

3. Austenitic-ferritic duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel and has superplasticity.

4. Martensitic stainless steel. High strength, but poor plasticity and weldability.

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 pipes in various industries:

Stainless steel pipe type
1. Stainless steel seamless pipe
Stainless steel seamless pipe is the use of cold drawn, cold rolled or cold extension process, without any seam steel pipe. Because the inner and outer walls of the seamless pipe are smooth and clean, it has excellent quality performance and is widely used in petroleum, chemical, aviation, metallurgy and other industrial fields. Stainless steel seamless pipe materials include 304, 304L, 321, 316, 316L, 310S and so on.
2. Stainless steel welded pipe
Stainless steel welded pipe is a steel pipe made by welding process. Due to its low production cost, easy production and other advantages, stainless steel welded pipe is widely used, such as food, petroleum, medicine, chemical and other industries. Stainless steel welded pipe materials are mainly 304, 316L, 321 and so on.

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

Stainless steel square pipe transport mode
1. Land transportation
The land transportation mode of stainless steel square pipe includes two ways of railway transportation and road transportation. Rail transport is relatively stable, while road transport is more flexible. In order to ensure transportation safety, stainless steel square pipes need to be packed with anti-rust, anti-leakage and anti-vibration to avoid wear due to friction during transportation. Packaging materials can use wooden pallets, wooden boxes, wooden frames, etc., but also need to pay attention to regular inspection, maintenance and maintenance during transportation.
2. Mode of shipping
For long-distance transportation, stainless steel square pipe shipping is usually a more economical and safe choice. When choosing sea transport, it is necessary to reasonably choose the appropriate ship type and loading scheme according to the actual situation of different goods, different seas and different seasons. In the process of shipping, it is necessary to package and transport in strict accordance with the national and relevant standards, which can prevent the goods from being affected by the environment, climate, temperature, humidity and other aspects to a certain extent.
