Factory Prefabricated Pipes (Prefab Pipes) are pre-assembled piping modules manufactured in a controlled factory environment before being transported to the construction site for installation. These pipes are custom-designed, pre-cut, pre-welded, and pre-insulated to meet project specifications, significantly reducing on-site labor and installation time.
1. Types of Prefab Pipes
Carbon Steel Prefab Pipes – Used in oil & gas, power plants, and industrial piping.
Stainless Steel Prefab Pipes – Ideal for chemical, food processing, and sanitary applications.
2. Features of factory prefabricated pipes:
Forming process: According to customer requirements, multiple products are assembled and welded together.
Production range: DN15-DN1800mm
Main materials: carbon steel, alloy steel, stainless steel, bimetallic composite, nickel-based alloy and other materials.
Application conditions: widely used in petrochemical, coal chemical, refining, oil and gas transportation, marine environment, electricity, heating and other projects.
Product features: rich production technology experience, advanced equipment, high degree of automation, high production precision, complete fetal membrane. Professional production technology is at the leading level in the same industry at home and abroad.
