In the oil and gas industry, types of pipes in oil and gas industry are employed, each tailored to specific functions and uses. Carbon steel pipes, a prominent type, are renowned for their durability and cost-effectiveness, making them prevalent across both upstream and downstream sectors.
Another key type is stainless steel pipes, such as A312 TP316L, which provide exceptional corrosion resistance, making them suitable for transporting corrosive fluids. Duplex and super duplex pipes are also crucial types, offering superior strength and corrosion resistance for challenging environments. Additionally, alloy steel pipes, built to endure high pressures and temperatures, are extensively used in refineries.
Polyethylene (PE) and composite pipes represent other vital types, known for their flexibility and environmental resistance, particularly in offshore and subsea applications. Each types of pipes in oil and gas industry plays an essential role in ensuring the robustness and efficiency of transportation systems.
