Cold bends are used to change pipeline direction while maintaining a smooth flow path. Manufactured through a controlled cold bending process, they are suitable for various pipeline systems in the oil and gas, petrochemical, water transportation, and power industries. Jinhang Pipeline provides cold bends in carbon steel, alloy steel, and stainless steel to meet different project requirements.
We offer customized cold bends based on customer specifications, including pipe material, outside diameter, wall thickness, bending angle, and bending radius. Available options can include seamless or welded pipes, with different end preparations and surface treatments. Each product can be specified according to project requirements to support reliable pipeline installation and operation.
