Grade B pipes are produced from carbon steel with a significant inclusion of manganese to its alloy. As a microalloying agent in API 5L Grade B Pipe, manganese is an element that causes an enhancement of several important properties. For instance, the pipes witness an increase in properties like tensile strength, hardness,...

ASTM A333 is mainly used for seamless steel pipes for low-temperature pressure vessel at -45℃ ~ -195℃ and low-temperature heat exchanger pipelines. ASTM A333 grade 6 is a standard covered seamless and welded carbon and alloy steel pipe for low temperatures, similar to AISI 4032 low alloy steel. The welding process should...

Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Hot-rolled carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel...

Application: It is suitable for stress and pressure parts, as well as steam, water, gas and air pipelines for general purposes.
