Stainless Steel Seamless Pipe

This product is TP304/316L stainless steel seamless pipe / precision tube. The picture shows industrial-grade seamless tubes marked with ASTM A213 TP304L/TP310S. Produced from solid billets through piercing, hot rolling and cold drawing processes, it has no welds, excellent sealing performance and high dimensional accuracy. It is the preferred pipe for petroleum refining, aerospace, precision instruments and high-end fluid equipment. Conventional specifications cover diameters from 6mm to 630mm, with wall thicknesses from 1mm to 50mm, supporting multi-material customization.

Product Performance

100% Zero Leakage/100%: Seamless structure has no heat-affected zone, completely eliminating weld leakage risks, suitable for flammable, explosive and high-purity medium transportation.
High Pressure Resistance: Dense internal structure endows seamless tubes with far higher internal pressure and impact resistance than welded tubes, suitable for high-pressure working conditions.
Excellent High Temperature Resistance: TP310S grade can be stably used in high-temperature environments below 1000℃, adapting to boilers and heat exchangers.
High Surface Finish: Cold-drawn/ground process results in smooth internal and external walls with low fluid resistance, meeting hygiene requirements for food and pharmaceutical industries.

Product Applications

High-end Chemical Engineering: Petroleum refining pipelines, high-temperature high-pressure steam pipes, and corrosion-resistant chemical medium pipes.
Food & Pharmaceutical: Food/beverage delivery pipes, pharmaceutical equipment pipelines, and sanitary-grade sterile piping systems.
Energy & Power: Nuclear power plant heat exchanger tubes, boiler tubes, and solar thermal power generation equipment.
Precision Machinery: Hydraulic cylinder rods, precision instrument sleeves, and sensor sheaths.

Features & Highlights

Seamless Zero Leakage: Fully welded structure with the highest safety factor, suitable for harsh working conditions.
High Temperature & Corrosion Resistance: Adapting to special materials such as 310S high temperature and 2205 strong corrosion resistance to meet non-standard requirements.
Precise Dimensional Control: Cold-drawing process achieves extremely small diameter tolerance for direct precision assembly.
Hygienic Grade Compliance: Can be treated with pickling passivation and electropolishing to meet hygiene standards such as FDA and GMP.
