PRODUCT INTRODUCTION
In recent years, the development trend of stainless steel welded tube is relatively good. Both the scale, quality and production technology have made great progress, especially in the field of demand. In addition, with the increasingly mature technology of stainless steel welded tube, stainless steel seamless tube can be gradually replaced in many application fields, such as heat exchange equipment, medium and low pressure boiler tube, etc.
Production characteristics of stainless steel welded tube:
light production equipment, less investment, fast construction speed, simple welding method, wide range of product specifications, high dimensional accuracy, small wall thickness deviation, smooth surface and high yield.
Advantages of stainless steel welded tube production:
1 The surface of stainless steel welded pipe is very smooth, not easy to scale, and has anti fouling function. It is not only conducive to heat dissipation, but also does not need to be cleaned frequently, saving time and labor;
2. Uniform wall thickness;
3. The length can be fixed arbitrarily with high precision;
4. Corrosion resistance and long service life.
Stainless steel welded tube shall be used for:
Oil and gas equipment, offshore technology, seawater desalination plant, chemical industry, bridge, storage tank, medical industry, civil engineering, reaction tank, heat exchanger, power plant, petrochemical, shipbuilding, etc
