Description

ASTM 106 Seamless Carbon Steel Pipe

ASTM A106 is a specification for seamless carbon steel pipe intended for high-temperature service. It covers various grades of carbon steel pipe, such as A, B, and C, which differ in their chemical composition and mechanical properties. ASTM A106 pipes are commonly used in industries such as oil and gas, power generation, and refineries due to their ability to withstand high temperatures and pressures.

Hydrostatic Test of A106 pipes:

The hydrotest shall apply a pressure equal to 60% of the minimum yield strength for at least 5 seconds at atmospheric conditions. The maximum pressure shall not exceed 2500 psi for pipes up to 3 inches, and 2800 for larger sizes. If additional, non standard, tests are executed the pipe shall bear an “S” mark on each lenght or pipe bundle.

Pipe marking:Each length of pipe (or bundle for smaller diameters) shall have the following markings applied:

ASTM A106 / ASME SA106 pipes are seamless carbon steel pipes used for high tempertaure applications (up to 750 degrees F). These pipes are widely used in the oil & gas, petrochemical, power generation and ship-building industries (examples: refineries, downstream plants, vessels. boilers and towers). A106 pipes are particularly suited whenever the transported fluid has either high temperature or high pressure (or both combined).

ASTM A106 / SA106 pipes are available in size range from 1/2 to 28 inches, and in pipe schedules from 10 to 160. These pipes are supplied either in single random lenght (17-24′) or double random lenght (36 -44′).
