ASTM A182 is a standard specification for forged or rolled alloy and stainless steel pipe fittings, which are primarily designed for high-temperature and corrosive service. This specification covers various grades of alloy steel pipe fittings, including flanges, forged fittings, and valves, that are suitable for use in pressure systems where elevated temperatures and aggressive environments are present.
The materials used in ASTM A182 alloy steel pipe fittings are carefully selected to ensure excellent mechanical properties and resistance to corrosion. These fittings are typically manufactured from low-alloy steels, such as ASTM A234 WP5, WP9, WP11, WP22, and WP91, which offer high strength, good weldability, and superior resistance to high-temperature environments.
ASTM A182 alloy steel pipe fittings are available in a wide range of sizes, shapes, and configurations to suit various industrial applications. The specification covers fittings such as flanges, elbows, tees, reducers, and caps, among others. These fittings are manufactured to precise dimensions and tolerances, ensuring compatibility and ease of installation.
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|
| WP5 | 415-585 | ≥205 | ≥20 |
| WP9 | 415-585 | ≥205 | ≥20 |
| WP11 | 415-585 | ≥205 | ≥20 |
| WP22 | 415-585 | ≥205 | ≥20 |
| WP91 | 585-760 | ≥415 | ≥20 |
ASTM A182 alloy steel pipe fittings undergo rigorous pressure testing to ensure their integrity and reliability. These fittings are subjected to hydrostatic or pneumatic tests, where they are pressurized to a specific level to detect any leaks or weaknesses. The pressure test ensures that the fittings can withstand the required pressure without failure, providing peace of mind for the end-users.
