TP304L -Austenitic stainless steel Industrial welded pipes
TP304L Features of stainless steel
Corrosion resistance: 304L stainless steel has good corrosion resistance, especially in oxidized environments such as air, water and most acidic solutions.
High temperature resistance: It can be used at temperatures up to 1000°C, with good high temperature strength and oxidation resistance.
Welding performance: 304L stainless steel is easy to weld, no heat treatment after welding.
Mechanical properties: with good toughness and plasticity, easy to process and molding.
Hygiene: In food processing and medical equipment, 304L stainless steel is widely used because of its good sanitary performance.
TP304L Production of stainless steel welded pipe
Raw material selection
Use 304L stainless steel sheet or strip for ASTM A312 / A312M or EN 10216-5 standard.
Molding
Process sheet or strip into pipe shape by cold rolling or cold drawing process.
Welding
Using TIG (tungsten pole argon arc welding) or MIG (metal inert gas protective welding). The welding parameters need to be strictly controlled during the welding process to ensure the weld quality.
Heat treatment
After welding, heat treatment is usually not required because 304L stainless steel has good welding performance.
Inspection and inspection
Conduct nondestructive testing of the welded pipe, such as ultrasonic detection, radiographic detection, etc., to ensure that the weld is without defects. Mechanical properties testing and corrosion resistance tests are performed simultaneously.
Surface treatment
According to the need, the welded pipe surface treatment, such as pickling, passivation, etc., to improve the corrosion resistance.
Packaging and delivery
Packaging and delivery: Packaging qualified welded pipes to ensure no damage during transportation.
TP304L Stainless steel welded pipes are very popular in industrial applications because of their excellent corrosion resistance and good welding properties. When selecting and using these materials, ensure that the appropriate standards and specifications are followed to ensure the performance and safety of the materials. At the same time, because 304L stainless steel has good processing performance and welding properties, it is very flexible in industrial manufacturing, can meet a variety of application needs.
