• Production process dimension and non-destructive testing (NDT)
• 100% pre-delivery inspection with photographic documentation

We accept third-party inspections from SGS and TUV to ensure compliance with international quality standards.

Professional packaging methods for different transportation scenarios:

• LCL transportation: plywood wooden boxes with plastic protective caps
• Full container transportation: woven bags with protective end caps

All packaging solutions are tested through global transportation practices to ensure safe delivery and immediate usability.

TP304L austenitic stainless steel features:

• Low-carbon characteristics (carbon content ≤ 0.03%)
• Excellent intergranular corrosion resistance
• Ideal for welding structures to prevent weld sensitization corrosion
• Superior mechanical properties and corrosion resistance
• Suitable for medium/low temperature and weak corrosive media environments

TP304L seamless pipe is widely used in:

• Oil and gas transportation pipelines
• Process pipelines in refineries and petrochemical plants
• Natural gas processing units
• Various weakly corrosive media environments

The material's excellent corrosion resistance and stable mechanical properties ensure long-term operational reliability while reducing maintenance and replacement costs.
