Stainless Steel 304L and 316L:
Grade 304 is a common material in stainless steel. It is a universal stainless steel with high temperature resistance of 800 ℃. It is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability). With good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.
The carbon content of 304L is lower than 0.03%; The carbon content of 304 is less than 0.08%.
In general, the corrosion resistance of 304L is similar to that of 304, but after welding or stress relief, 304L has excellent intergranular corrosion resistance. 304L stainless steel is low-carbon stainless steel, mainly applicable to welding process. During welding, the low carbon content of 304L stainless steel reduces the carbide precipitated in the heat affected zone near the weld, effectively improves the resistance to intergranular corrosion of stainless steel, and prolongs the service life of stainless steel welds.
316L is a derivative steel of austenitic stainless steel. Because the steel contains molybdenum, its overall performance is better than 310 and 304 stainless steels. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% or higher than 85%, 316L stainless steel has a wide range of uses.
The Mo content of 316L makes the steel have excellent corrosion resistance and can be safely used in the environment containing Cl - and other halogen ions. As the 316L is mainly used for its chemical properties, the steel plant has slightly lower requirements on the surface inspection of the 316L (compared with 304), and customers with higher requirements on the surface should strengthen the surface inspection. 316L stainless steel also has good chloride corrosion resistance, so it is usually used in marine environment.
Features of 316L stainless steel
1) Excellent high temperature strength;
2) Due to the addition of Mo, the corrosion resistance, especially the pitting resistance, is excellent;
3) The appearance of cold rolled products is glossy and beautiful;
4) Non magnetic in solid solution state;
5) Excellent work hardening (weak magnetism after working);
6) The price is higher than 304 stainless steel.
What is Spiral Wound Tube?
Spiral Wound Tube (SWT) is a type of pipe construction made by alternately winding metal strips with packing. This type of pipe construction is often used to make sealing elements such as packing gaskets and sealing washers to ensure the tightness of pipes and vessels.
Main features and applications:
Structural Design: Spiral-wound pipe construction consists of metal strips and packing that are alternately wound to form a spiral-like structure. This design provides flexibility and pressure resistance.
Material Selection: Commonly used metal belts include stainless steel, copper, and aluminum, while the packing is usually made of soft materials such as flexible graphite, polytetrafluoroethylene (PTFE), etc. This allows spiral wound tubes to be used in a variety of applications. This allows spiral wound pipe to remain stable in a wide range of chemical and temperature environments.
Sealing Performance: Due to its special structure, spiral wound pipe can provide excellent sealing performance under high temperature, high pressure or corrosive media, so it is widely used for sealing pipes, valves and pressure vessels.
Applications: Spiral-wound pipes are mainly used in industrial fields, such as petrochemical, chemical, energy, etc., especially where efficient sealing and corrosion resistance are required.
