Supply & Demand

Structural and pile pipes, predominantly fabricated from carbon steel and low - alloy steel, provide high strength and outstanding corrosion resistance. These pipes are mainly utilized for supporting building structures and reinforcing foundations in various construction projects, including buildings, piers, bridges, highways, and railways. They directly bear loads, enhance ground load - bearing capacity, and improve the bank protection ability of piers.

API SEPC 5L, GB/T 9711 - Petroleum and Natural Gas Industries: Steel Pipes for linepipe Transportation Systems; GOST 20295 - Welded Steel Pipes for Oil and Gas Pipelines. Linepipes are mainly utilized for the transportation of fluids, including oil, natural gas, hydrogen, and carbon dioxide. Usually fabricated from steel grades ranging from L245 to L480, these pipes exhibit high pressure resistance, low - temperature tolerance, and corrosion resistance, which allows them to operate in harsh environments such as extreme cold, humid heat, and marine conditions. These pipes can be connected through welding, threading, or flanging to facilitate long - distance transportation.
