1. Introduction: Installation quality determines the lifespan of pipelines.

After precise specification selection, the success or failure of a project then shifts to the construction site. As a professional supplier of ASTM A106/A53 & API 5L seamless steel pipes, we understand that even the highest-grade steel pipes, without scientific Installation Best Practices, can become the weakest link in a system operating under high pressure.

2. Welding conditions: Advantages of low carbon equivalent and connection standards

  • Excellent Weldability: Our ASTM A106 & API 5L Grade B pipes feature strictly controlled carbon equivalent (CE), resulting in superior welding compatibility that significantly reduces the risk of cold cracking. Even under harsh field conditions during butt welding, perfect fusion between the weld metal and base material is ensured.
  • Heat-Affected Zone Control: Precise chemical composition minimizes the heat-affected zone (HAZ) during welding, preventing localized toughness reduction caused by grain coarsening and ensuring that every weld passes 100% radiographic testing (RT) standards.

3. Connection Technologies: A diverse range of options to ensure zero leakage.

  • Flange Assembly: For industrial pipelines requiring regular maintenance or cleaning, flange connections provide a secure and removable solution. We recommend strictly following the torque sequence during assembly to ensure even pressure on the gasket.
  • Threaded Connections: In small-diameter and low-pressure water supply and drainage systems, precisely machined tapered pipe threads, combined with high-quality sealing materials, enable rapid deployment and are the best choice when hot work is not permitted on-site.

4. Bending and cold working: Ensuring mechanical strength.

  • Excellent Flexibility: Our tubing exhibits outstanding bending properties. When cold-formed within the minimum bending radius, the tube wall will not show wrinkles or microcracks.
  • Structural Integrity: Even after cold bending, the seamless tube's microstructure remains isotropic, ensuring fatigue strength at the bends under high-pressure cyclic loading, meeting the requirements of complex piping designs.

5. Galvanized coating protection: Post-installation corrosion protection measures.

  • On-site repair specifications: We recommend cleaning the oxide scale from the weld area immediately after welding and performing galvanized coating repair.
  • Double barrier protection:  Applying multiple layers of zinc-rich paint with a very high zinc content not only covers the exposed carbon steel surface but also extends the overall system's corrosion resistance through electrochemical principles, ensuring the installed piping system remains "indestructible" even in acidic or humid environments.

A perfect installation process can significantly reduce hidden costs associated with on-site rework, while a cost-effective source procurement plan is key to project profitability.
