347 Stainless Steel Pipe is a popular piping material known for its excellent corrosion resistance and high-temperature strength. The pipe is made from 347 stainless steel, which is a high-performance alloy that contains chromium, nickel, and columbium. The pipe is used in various industries, including petrochemicals, oil and gas, and automotive. The following are some of the specifications and technical parameters of 347 Stainless Steel Pipe.
Specifications:
- Material: 347 stainless steel
- Size: 1/8" to 48" NB (DN6 to DN1200)
- Wall thickness: Sch10 to Sch XXS
Production process:
The pipe is produced using the seamless or welded process. The seamless process involves heating a solid billet of 347 stainless steel, and then piercing it with a mandrel to create the desired shape. The welded process involves rolling a flat sheet of 347 stainless steel into a tube and then welding the seam. After the production process, the pipe is subjected to various tests to ensure quality control.
Processing technology:
The pipe can be processed using various techniques such as annealing, pickling, polishing, grinding, and cutting. Annealing helps to improve the ductility, toughness, and corrosion resistance of the pipe, while pickling removes any surface impurities. Polishing and grinding are done to achieve a smooth and shiny surface, while cutting is done to achieve the desired length of the pipe.
Application:
347 Stainless Steel Pipe is widely used in various industries due to its high-temperature strength and excellent corrosion resistance. The pipe is commonly used in the following applications:
- Petrochemicals: For conveying various chemicals and petroleum products.
- Oil and gas: For conveying crude oil, natural gas and other petroleum products.
- Automotive: For exhaust systems and other high-temperature applications.
Technical parameters:
- Tensile strength: 620 MPa
- Yield strength: 330 MPa
- Elongation: 35%
- Hardness: 180 to 200 HB
Usage instructions:
347 Stainless Steel Pipe should be handled with care to avoid damage during transportation and storage. During installation, the pipe should be properly aligned to avoid bending or twisting. The pipe should be protected from any corrosive substances or chemicals that could cause damage. Regular maintenance and inspections should be carried out to ensure the pipe remains in good working condition.
