ASTM A106 Grade B is a seamless carbon steel pipe that is commonly used for high-temperature service in various industries, such as oil and gas, petrochemical, power generation, and refineries.

ASTM A335 P11 P12 P22 steel pipe is a low carbon steel with specific chemical composition and mechanical property requirements, and its hardness and strength can be improved through different heat treatment methods.

The slotted casing pipes using in oil exploration can prevent 99% sand, decrease 80% of oil well heavy maintenance, as well increase the strength of the oil well, integrality and stability of keeping sand off.
