Stainless steel welded pipe is a tubular product made of stainless steel strip or steel plate through curling, welding and other processes. It is formed into a steel pipe with a certain diameter, wall thickness and length by processing the raw materials, and the weld is an important feature of its structure.
Characteristics of stainless steel welded pipes
1. Corrosion resistance
The main material of stainless steel welded pipes is stainless steel, which has excellent corrosion resistance and can resist the erosion of many chemical substances such as acid, alkali, salt, etc. This makes stainless steel welded pipes widely used in chemical, petroleum, pharmaceutical and other industries.
2. High strength
Stainless steel welded pipe has high strength and hardness, and can withstand high pressure and load, which makes it an important structural material in the fields of construction, bridges, machinery, etc.
3. Good weldability
Stainless steel welded pipes have good weldability and can be connected and assembled through welding and other processes to meet various complex structural and process requirements.
4. Smooth and beautiful surface
The surface of stainless steel welded pipe is smooth and bright, with good decorative effect. At the same time, it is easy to clean and maintain, and maintains a long-lasting appearance.
5. High and low temperature resistance
Stainless steel welded pipes can maintain stable performance at both high and low temperatures, and will not deform or crack significantly due to temperature changes. This allows it to work reliably in both high and low temperature environments.
6. Lightweight
Compared with other metal materials, stainless steel welded pipes have a lower density, lighter weight, and are easier to carry and install. This reduces construction costs and improves construction efficiency.
7. Environmental protection
Stainless steel welded pipes have little impact on the environment during production and use, and meet environmental protection requirements. At the same time, due to its corrosion resistance, it reduces waste and environmental pollution caused by corrosion.
What are the types of stainless steel welded pipes?
1. Classification by welding technology
Stainless steel welded pipes can be divided into automatic welding and manual welding. Automatic welding generally uses submerged arc welding, plasma welding and other methods, while manual welding usually uses argon arc welding.
2. Classification by weld type
Stainless steel welded pipes can be divided into straight seam welded pipes and spiral welded pipes. Straight seam welded pipe refers to a type of pipe that is welded along the main axis of the steel pipe, while spiral welded pipe is a steel pipe made of annular steel plates that is formed into a spiral weld after being roller-formed.
3. Classification by purpose
Stainless steel welded pipes can be divided into general welded pipes, heat exchanger tubes, condenser tubes, galvanized welded pipes, oxygen-blown welded pipes, wire casings, metric welded pipes, roller pipes, deep well pump pipes, automobile pipes, transformer pipes, electric welded thin-walled pipes, electric welded special-shaped pipes, etc.
4. Classification by material
In terms of the material of stainless steel welded pipe, there are mainly austenitic types (AISI, ASTM), ferrite and martensitic types (AISI, ASTM). Common models include 304, 304L, 316, 321, etc. Among them, 304 is a commonly used model, generally used in food machinery and surgical equipment, etc.
5. Classification by shape
Such as round tubes, square tubes, rectangular tubes and oval tubes, etc. These stainless steel tubes in different shapes have their unique application scenarios and advantages.
