Seamless Pressure Pipe (also known as ASME SA106 Pipe) is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gasses that exhibit higher temperatures and pressure levels.
ASTM A106 Seamless Pressure Pipe (also known as ASME SA106 Pipe) covers seamless carbon steel nominal wall Pipe for high-temperature service. Suitable for bending, flanging and similar forming operations.

ASTM A106 Pipe (also covered in ASME specifications as S/A 106) is the standard specification for seamless carbon steel Pipe for high-temperature service. Most common uses are in refineries and plants when gasses or fluids are transported at high temperatures and pressures.EMHK is the supplier of A106 / SA 106 Pipe and stocks a full range of grades B/C in a size rage of NPS 1/8″ to NPS 48″, with nominal (average) wall thickness as given in ANSI B36.10. Pipe having other dimensions may be furnished provided such Pipe complies with all other requirements of this specification. Pipe ordered under this specification shall be suitable for bending, for flanging, for welding, and for similar forming operations. A full range of A106 stock is available in Schedules 10 through 160, STD, XS, XXS. Unscheduled wall thicknesses available up to 4 inches.

The chemical composition of the material back does not correspond to the domestic answer material, and the electron performance is similar to that of the domestic (GB/T699)20-steel
ASTM is a set of U.S. steel pipe standards, ASTM steel pipe A106A corresponding to the Chinese standard is GB8163 material for 10# , steel, A106B corresponding to the Chinese standard is GB8163 material for 20 #.
Mechanical Tests Specified A106 Grade B Carbon Steel Seamless Pipe
Tensile Test — NPS 8 and larger — either transverse or longitudinal acceptable
Smaller than NPS 8 — weighed in lots. Larger sizes — by length.
Flattening Test — NPS 2-1/2 and larger.
Bending Test (Cold) — NPS 2 and under
Hydrostatic Testing A106 Grade B Carbon Steel Seamless Pipe
Inspection test pressures produce a stress in the Pipe wall equal to 60% of specified minimum yield strength (SMYS) at room temperature. Maximum Pressures are not to exceed 2500 psi for NPS3 and under 2800 psi for the larger sizes. Pressure is maintained for not less than 5 seconds.
