321 stainless steel pipe specification: The standard size of 321 stainless steel pipes is 1/8" to 30" NB, SCH 10 to SCH 80, and the length of the pipes is 6 meters, 12 meters or customized as per customer requirements.
Production process and manufacturing technique: 321 stainless steel pipes are manufactured through the hot and cold forming process. Firstly, the stainless steel slab is heated until it reaches its melting point. Then, it is passed through a rolling machine that compresses the molten steel into the desired shape. The pipe is then welded and annealed to improve its strength and durability.
Usage and application: 321 stainless steel pipes are widely used in chemical, petrochemical, food processing, paper, sewage treatment plants, and other industries. Moreover, it is used in high-temperature applications due to its excellent high-temperature resistance, low thermal expansion, and good corrosion resistance.
Technical parameters: The technical parameters of 321 stainless steel pipes include its strength, elongation, hardness, and corrosion resistance. The ultimate tensile strength ranges from 515 to 730 MPa, while the elongation is between 35 to 45. Its hardness is 187 Rockwell B, and it offers good resistance to pitting and crevice corrosion.
Instructions for use: 321 stainless steel pipes are recommended to be used in high-temperature environments, as well as acidic and corrosive environments. They should be stored in a cool and dry place to avoid rusting and kept away from moisture and direct sunlight. Before installation, the pipes must be thoroughly cleaned and inspected to ensure their quality and integrity.
