304/304L Stainless Steel Pipe & Tube – Seamless and Welded

Product Overview

Wuxi Xinshanhu Steel Co., Ltd. supplies high-performance 304 and 304L stainless steel piping solutions. While Grade 304 offers exceptional corrosion resistance and formability for general industrial use, Grade 304L (Low Carbon ≤0.03) prevents carbide precipitation during welding, making it the definitive choice for heavy-gauge welded structures and high-corrosion environments. Available in both structural welded and high-pressure seamless configurations to match your precise engineering blueprints.

Available Types and Specifications

Product Advantages

Superior Corrosion Resistance: Excellent durability in atmospheric environments and many corrosive media.
Intergranular Corrosion Prevention: 304L grade eliminates the risk of weld-decay, ensuring safety in heavy-duty welded joints.
High Pressure & Temperature Rating: Seamless variants engineered to withstand extreme mechanical stress and high-pressure environments.
Exceptional Surface Integrity: Smooth inner and outer walls prevent scaling and optimize fluid flow dynamics.

Applications

Food processing and kitchen equipment
Chemical and pharmaceutical pipelines
Marine and architectural structures
Heat exchangers and fluid transportation
