Aviation Standard Superalloy AMS 316 Zecor-Z Uns38815 Uns S32750 Austenitic Stainless Steel Tube Cold Drawn Hastelloy X Stainless Steel Pipe

Steel Boiler Pipe is a type of seamless steel pipe that is specifically designed to withstand high pressure and temperatures in boiler and heat exchanger applications. It is made from high-quality carbon steel or alloy steel and is often used in power plants, refineries, and other industrial settings. Steel Boiler Pipe is available in various grades and sizes, and can be customized to meet the specific needs of different applications. With its superior strength, durability, and resistance to corrosion, Steel Boiler Pipe is a reliable and cost-effective solution for demanding industrial environments. 

ASTM A213 seamless pipes tubes Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes. Grades containing the letter H in their designation have requirements different from those of similar grades not containing the letter H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements. The tubes shall be made by the seamless process and shall be either hot finished or cold finished, as specified. Grade TP347HFG shall be cold finished. Heat treatment shall be done separately and in addition to heating for hot forming. The ferritic alloy and ferritic stainless steels shall be reheated. On the other hand, austenitic stainless steel tubes shall be furnished in the heat-treated condition. Alternatively, immediately after hot forming, while the temperature of the tubes is not less than the minimum solution temperature, tubes may be individually quenched in water or rapidly cooled by other means. Tension test, hardness test, flattening test, and flaring test shall be done to each tube. Also, each tube shall be subjected to the nondestructive electric test or hydrostatic test.

ASTM A192 / A192M is the standard applicable to seamless carbon steel boiler tubes for high-pressure service
ASTM A192 seamless steel tube sizes and thicknesses usually furnished to this specification are 1⁄2 in. to 7 in. [12.7 to 177.8 mm] outside diameter and 0.085 to 1.000 in. [2.2 to 25.4 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
ASTM A192 seamless steel tubes mechanical property requirements do not apply to tubing smaller than 1⁄8 in. [3.2 mm] inside diameter or 0.015 in. [0.4 mm] thickness.
