SMLSCO maintains 2,000 tons of seamless pipe inventory with ample 3" TP310S high-pressure pipes ready for shipment within two weeks. Bulk raw material sourcing reduces costs while dual ISO + PED compliance ensures rapid replenishment and improved cash flow turnover for global distributors.
Every TP310S pipe undergoes comprehensive quality assurance:
- PMI spectrometry upon material arrival
- Combined eddy current (EC) and ultrasonic testing (UT)
- 100% dimensional and visual inspections with photo documentation
- Third-party SGS/TUV sampling reports available
- Full traceability guaranteeing batch consistency and stability
- LCL shipments: Plywood crates + plastic end caps
- FCL shipments: Woven sacks with bundled protection + end caps
All crates and pallets comply with ISPM-15 phytosanitary standards, enabling direct entry into European automated warehouses to minimize transit damage and client reprocessing costs.
This product undergoes a seven-step manufacturing process:
- Perforation
- Multi-pass cold drawing
- Solution annealing
- Acid pickling and passivation
- Eddy current testing
- Straightening
- Finished product inspection
Each step is precisely controlled by CNC equipment to ensure dimensional consistency, wall thickness uniformity, and inner wall cleanliness. Multi-pass cold drawing finishing refines grain size and increases strength by more than 15%, with dimensional tolerance controlled within ±0.05mm and inner surface roughness ≤0.8μm.
Material Composition: TP310S contains 25% Cr and 20% Ni, delivering oxidation resistance up to 1100°C alongside high-temperature strength and chloride corrosion resistance.
Applications: 3" thick-walled TP310S seamless pipes are widely used in:
- Heat treatment furnace tubes
- Petrochemical cracking furnaces
- Heat exchangers
- High-temperature flue gas pipelines
- Combustion systems
The low-carbon formulation minimizes high-temperature sensitization risks, making it ideal for prolonged high-pressure/high-temperature cyclic environments in refinery, chemical, and energy applications.
