ASME ANSI B36.10/ASME ANSI B36.19 Specifications

ASME ANSI B36.10 and ASME ANSI B36.19 are two separate sets of specifications that relate to steel pipe dimensions and wall thickness.

ASME ANSI B36.10 is the standard for welded and seamless wrought steel pipe with nominal sizes ranging from 1/8 inch to 80 inches in diameter. This specification covers the dimensions, tolerances, and schedules for carbon, alloy, and stainless steel pipes. It also includes requirements for threading and threading allowances.

ASME ANSI B36.19, on the other hand, covers the dimensions and tolerances of stainless steel pipes and tubes that are used in high-temperature and corrosive environments. This specification covers the seamless, welded, and heavily cold worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service.

Both specifications provide detailed information concerning the standard sizes, weights, and dimensions of different types of steel pipes. They also provide guidelines on the manufacturing process and the various materials used in the production of steel pipes. These specifications are widely used by manufacturers, engineers, and architects to ensure that their products meet the required standards for quality and performance.

ANSI B36.19 Wall thickness grade: Sch5s, Sch10s, Sch40s, Sch80s four grades.
ASME / ANSI B36.10 seamless steel pipe and welded steel pipe and ASME / ANSI B36.19 stainless steel pipe: steel pipe size, diameter, wall thickness, pressure, and other work.

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
