Alloy Steel Pipes for High Temperature Service
Large diameter alloy steel pipes are those with an outer diameter exceeding 100 mm, wall thickness greater than 0.2, and the outer diameter of a pipe, and Large diameter alloy steel pipes are pierced with steel ingots or solid pipes, and then hot-rolled, cold-rolled, or cold dialed.
WB36 is a bainitic Ni-Cu-Mo steel micro-alloyed with niobium according German standards DIN WB36 .
The alloying elements in ASTM A335 P91 Alloy steel Seamless Pipes tend to make either compounds or carbides or solid solutions.
A335 P22 pipe is a kind of chrome moly pipes (ASME S/A335, Chrome-Moly) listed in ASTM A335, which has become a standard in the power generation industry and the petrochemical industry, not only because of its tensile strength, corrosion resistance and high-temperature strength, but also because of its cost-effectiveness.
ASTM A335 P11 steel is a ferritic alloy steel. This material has been in use successfully in power plant service.
