There is a large selection of ASTM A213 Tube Stockist China offer by the Hunan Ronggang Steel Industry. They offer Wholesale Various High-Quality Astm A213 Tube in any specifications the customers require, in all shapes and sizes.

Boiler, superheater, and heat-exchanger tubes made of seamless ferritic and austenitic alloy steel are specified by ASTM A213.

ASTM A213

Tubing made to ASTM A213 (ASME SA213) has been use extensively in high-temperature applications, particularly for boiler and superheater applications. Alloy and stainless steel can be use to make seamless tubes that are either hot roll or cold drawn. Therefore, this pipe is typically use in very important locations and is much more expensive than typical carbon pipes. T9, T11, T12, T21, T22, T91, and stainless grades in TP304 or TP316 are typical grades.

ASTM A213

Boiler, superheater, and heat-exchanger tubes made of seamless ferritic and austenitic steel are cover by the ASTM A213 Standard. The requirements for grades with the letter H in their designation differ from those for comparable grades without the letter H. Higher creep-rupture strength is possible with these different requirements than is typically possible in grades with similar compositions. The tubes must be produced using a seamless technique and finish either hot or cold, depending on the requirements. Cold finishing is require for grade TP347HFG. Separately from and in addition to heating for hot forming, heat treatment must be carry out. Reheating is require for the ferritic alloy and ferritic stainless steel. However, austenitic stainless steel tubes must be deliver in a heat-treated state. Alternatively, tubes may be individually quenched in water or rapidly cool by other means after hot forming as long as their temperature is not lower than the minimum solution temperature. Each tube must undergo tension testing, hardness testing, flattening testing, and flaring testing. Each tube must also pass a hydrostatic test or a nondestructive electric test.
