ASTM A106 Grade B Carbon Steel Pipes And Tubes Boiler Fitted MTC Certificated
As we know ASTM A106 Grade B pipe is one of the most popular seamless steel pipes applied in different industries. Not only in pipeline systems like oil and gas, water, mineral slurry transmission, but also for boiler, construction, structural purposes.
ASTM A106 Grade B Carbon Steel Seamless Pipes are commonly used in
low and middle pressure fluid pipeline, boiler, petroleum and
natural gas industry, drilling, chemical industry, electrical
industry, shipbuilding, fertilizer equipment and pipeline,
petrochemical.
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.
1. Standards
ASTM A106 ——Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service
ASTM A335 ——Standard Specification for Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service
2. Application
For the high-pressure boiler and steam pipes, and the petrochemical
industry pipes;
Power plant; Chemical Fertilizer; Petrochemicals; Offshore Oils;
Gas Productions; Refineries and etc.
