ASTM A106 pipe is the standard specification for seamless carbon steel pipe for high-temperature service. Applications are transport gasses or fluids in refineries and boiler plant bearing high temperatures and pressures. Pipe produced according to ASTM A106 shall be suitable for bending, flanging, welding and other forming operations.Tiancheng Group supplies astm a106 grade b seamless pipe and erw pipe, if you are interested in buying ASTM A106 pipe, don't hesitate to contact us now!
For ASTM A106 seamless steel pipe could transport fluids or gasses at high temperature and pressure levels, with 3 grades A, B, C, most common used ASTM A106 Grade B is widely used in the projects of oil and gas refineries, power plants, petrochemical plants, boilers.
