Energy Infrastructure

Oil & Gas Transmission

High-performance pipe systems for upstream gathering, midstream transmission, and downstream distribution networks.

Overview

JO STEEL supplies carbon and alloy steel pipes engineered for the demanding conditions of oil and gas transmission. From wellhead gathering lines to long-distance trunk pipelines, our products meet API 5L PSL 2 specifications and support sour service, high-pressure, and subsea applications across the energy value chain.

The Challenge

Oil & gas transmission requires pipe systems capable of handling corrosive fluids, extreme pressures, and temperature fluctuations while maintaining structural integrity over decades of service in remote or offshore environments.

Our Solution

We provide API 5L PSL 2 seamless and welded line pipe in grades from X42 to X80, with full traceability, third-party inspection, and coating options including 3LPE, FBE, and concrete weight coating for subsea installations.
