Full Range Industrial Steel Pipes: Seamless, Precision & Welded Pipe Introduction

Steel pipes are essential metal components for modern engineering, machinery and fluid transportation. At Shandong Xinzhongding Metallurgy, we supply three mainstream steel pipe products to meet different industrial demands.

1. Seamless Steel Pipe Made by hot rolling perforation of solid steel billets without welding seams, seamless pipes feature high pressure resistance and strong structural stability. Common materials include 20#, 45#, Q345B and alloy steel. They are widely used for oil & gas transportation, boiler pipelines, high-pressure fluid delivery and building pile foundations.
2. Precision Cold Drawn Steel Pipe Processed through multiple cold drawing and bright annealing procedures, precision tubes have ultra-small dimensional tolerance and smooth inner walls without oxide scale. Customers can directly assemble them without secondary machining. These pipes are ideal for hydraulic cylinder barrels, automotive parts, new energy equipment and precision machinery.
3. ERW Straight Welded Pipe Produced by high-frequency steel strip rolling welding, welded pipes have cost advantages and stable supply capacity. Mainly made of Q235B carbon steel, they are popular for building scaffolding, greenhouse frames, guardrails, low-pressure water and gas pipelines.

All our steel pipes strictly implement GB, ASTM and API international standards. We provide customized outer diameter, wall thickness, length and anti-rust treatment such as painting and hot galvanizing. If you have special technical requirements for mechanical performance, our technical team can adjust production parameters to match your project standards.
