Jacket Offshore Platform Structure Pipe

Jacket Frame Offshore Platform Structural JCOE LSAW Steel Pipe

Product Overview

Our jacket frame offshore platform structural tube belongs to JCOE double-sided submerged arc welded straight seam steel pipe. After precise forming and finishing treatment, both inner and outer tube surfaces achieve smooth flat finish. This product covers two major application categories:

Fluid transportation: Suitable for long-distance delivery of onshore & offshore crude oil, natural gas, coal water slurry, mineral slurry and various industrial mediums;

Load-bearing structural engineering: Serves as frame and foundation structural pipes for marine jacket platforms, power generation stations, petrochemical plants, municipal high-rise buildings and urban infrastructure projects.

Core Product Strengths

Every finished pipe undergoes integral mechanical expanding post welding forming. This process drastically cuts residual internal stress inside tube bodies and distributes stress evenly across the whole wall, effectively eliminating stress corrosion cracking risks under harsh marine working environments.

Ultra-high dimensional precision with consistent roundness and outer diameter, simplifying field butt welding construction;

Compared with spiral welded pipes, straight weld length is far shorter, greatly lowering the occurrence rate of welding defects and lifting overall structural safety;

Smooth inner & outer walls reduce fluid flow resistance and prevent residual medium buildup inside the pipeline.
