ASTM A106 Grade B Seamless Pipe for High Temperature Service
ASTM A106 Grade B seamless pipe covers seamless carbon steel nominal wall pipe for high-temperature service which is suitable for bending, flanging and similar forming operations. NPS 1-1/2” or below may be either hot finished or cold drawn whereas NPS 2” or greater shall be hot finished unless otherwise mentioned. Weight of any pipe length does not vary more than 10% over and 3.5%. Larger sizes are weighed separately by length.
A106 Grade B Carbon Steel Pipes Manufacturer in China
Our company pays close attention to quality and safety management and we already obtained the certificates of ISO9001 Quality Management System, ISO14001 Environment Management System, API certificate, and the manufacturing license of pressure pipeline.We supply seamless type A106 Grade B carbon steel pipes, A106 Gr.B Black Steel Pipes, ASTM A106 Grade B seamless (Zinc) pipes & SA53 Gr.B Schedule 40 seamless pipes worldwide.
These seamless type ASTM A106 Grade B carbon steel pipes are suitable for welding, bending, flanging, and similar forming operations. Mechanical testing of the specimens shall include tensile, bending, flattening, hydrostatic and nondestructive electric tests. Specimens undergoing bending tests shall consist of sections cut from a pipe. For flattening tests, the specimens shall be smooth on the ends and burr-free, except when made on crop ends. All tests shall be performed in room temperature.

Seamless Steel A106 Steel Pipes Test Certificates
We at GIC provide Manufacturer TC (Test Certificate) in accordance to EN 10204/3.1B, Raw Materials Certificate, 100% Radiography Test Report, Third Party Inspection Report. We also provide Standard certificates like EN 10204 3.1 and additional requirement like. NACE MR 01075. FERRIT CONTENT as per norms if requested by clients.
• EN 10204/3.1B,
• Raw Materials Certificate
• 100% Radiography Test Report
• Third Party Inspection Report, etc
A106 Grade B Steel Pipes Testing Requirement:
• Mechanical Testing Such as Tensile of Area
• Hardness Test
• Chemical Analysis – Spectro Analysis
• Flattening Test
• Bending Test
• Pitting Resistance Test
• Flaring Test
• Hydrostatic Testing: 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 2,500 psi for NPS 3" and under, and 2,800 psi for larger sizes. Pressure is maintained for no less than 5 seconds.
Carbon Steel A106 Seamless Pipes Packaging
Carbon Steel A106 Gr.B seamless pipes may be furnished bare or coated and with capped ends. pipes up to 3”OD will be supplied in bundles. In order to prevent rust during sea shipment, bundles of Carbon Steel grade b Pipe may be wrapped with polypropylene sheets, and secured with flat steel bands. Over 3” OD will be supplied loose.
ASTM A106 Grade B carbon steel seamless pipes (also known as ASME SA106 Grade B pipe) are commonly used in the construction of oil and petrochemical plants,gas refineries, power plants, boilers, and ships where the piping must transport fluids and gasses that exhibit higher temperatures and pressure levels Surface finish standards are outlined in the specification.
