ASME SA312 TP317L Welded Pipe For High Temperature Service

TP317L is a chromium nickel molybdenum alloy that can perform under high temperatures. The alloy is solid solution heated for strength and the pipes are produced through different manufacturing mechanisms. The SA 312 TP 317L products have high yield strengths and can perform well under stress conditions. They have elongation rate higher than 35%.

Key Features of A312 TP317L Welded Pipe:

1. Material Composition:
- TP317L is a low-carbon version of the 317 stainless steel grade, which typically includes:
- Chromium: 18-20%
- Nickel: 11-15%
- Molybdenum: 3-4%
- Manganese, Silicon, and trace amounts of other elements.
- The low carbon content helps reduce the risk of carbide precipitation during welding, enhancing corrosion resistance.

2. Corrosion Resistance:
- TP317L offers excellent resistance to a wide range of corrosive environments, including chlorides, making it suitable for applications in chemical processing, oil and gas, and marine environments.

3. High-Temperature Resistance:
- The pipe can withstand high temperatures, making it suitable for applications that involve heat, such as power generation and heat exchangers.

4. Welding and Fabrication:
- Being a welded pipe, TP317L can be produced in long lengths and can be easily fabricated and welded, allowing for flexibility in construction and installation.

5. Applications:
- Common applications for A312 TP317L welded pipes include:
- Chemical and petrochemical processing
- Oil and gas industries
- Power generation
- Pulp and paper manufacturing
- Food and beverage processing
- Pharmaceutical manufacturing

6. Standards and Specifications:
- The pipe is manufactured in accordance with ASTM A312/A312M specifications, which outline the requirements for the manufacture, testing, and quality assurance of stainless steel pipes.

7. Sizes and Schedules:
- A312 TP317L welded pipes are available in various sizes and wall thicknesses (schedules), accommodating different pressure and temperature requirements.
