    Packing & Loading

    High temperature alloy steel tubes are known as chrome moly pipe.

    ASTM A213, A209 specification covers alloy steel seamless tube for high temperature service. Seamless alloy steel tubes are suitable for bending and similar forming operations, and for fusion welding at high temperatures. High temperature alloy steel tube are also considered as low alloy chrome moly grades.

    ASTM/ASME A/SA335 Gr. P1, P2, P5, P11, P12, P22

    ASTM/ASME A/SA209 T1, T1a, T1b

    ASTM A213 tubing has been widely used in high temperature services especially for the boiler and superheater. Tube material could be in alloy steel and stainless steel, and manufactured in seamless of hot rolled or cold drawn. Common grades are T9, T11, T12, T21, T22, T91 and stainless grades in TP304 or TP316.

    The A335 pipes are generally called chrome moly pipe, it is a type of seamless pipe could be used in high temperature environments of 540 – 750 °C, they have a high level of Chromium and Molybdenum presence in it, While Molybdenum increases the overall strength, resistance, elasticity, hardenability and overall quality, moly ensures that the material is more resistant to softening, restrains the growth of grains and lessens the chances of embrittlement. It is the single additive that is responsible for the increase in high temperature resistance and it also improves the corrosion resistance to steel.

    This chrome moly pipe featured grades are ASTM A335 P9, P11, P22, P91, so also it could be called as P Grade pipe in some cases.

    P11 pipe, P22 pipe and P91 pipes are used in power industry and petro-chemical plants, meanwhile, P5 and P9 pipe generally find usage in refineries.

    ASTM A209 / A209M, ASME SA209 T1, T1a, T1b is the standard applicable to seamless carbon-Molybdenum Alloy-Steel Boiler and Superheater Tubes.
