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 eliminates incoming inspection burdens for global distributors—ensuring rapid replenishment and improved cash flow turnover.
Every TP310S pipe undergoes PMI spectrometry upon arrival. Production stages include combined eddy current (EC) and ultrasonic testing (UT). 100% dimensional and visual inspections with photo documentation precede shipment. Third-party SGS/TUV sampling reports are available, with full traceability guaranteeing batch consistency and stability.
All crates/pallets comply with ISPM-15 phytosanitary standards, enabling direct entry into European automated warehouses to minimize transit damage and client reprocessing costs.
This product adopts a seven step process of 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, meeting the requirements of distributors for high compliance and high turnover inventory.
Multi pass cold drawing finishing: Through continuous cold drawing and intermediate annealing, the grain size of the pipe is refined, and the strength is increased by more than 15%; The final dimensional tolerance can be controlled within ± 0.05 mm, with an inner surface roughness of ≤ 0.8 µ m, fully ensuring the reliability of heavy wall pipes in high-pressure sealing situations and providing more competitive spot selection for inventory suppliers.
310S Material Properties: TP310S contains 25% Cr and 20% Ni, delivering oxidation resistance up to 1100 °C alongside high-temperature strength and chloride corrosion resistance. Its low-carbon formulation minimizes high-temperature sensitization risks, making it ideal for prolonged high-pressure/high-temperature cyclic environments. This provides distributors with reliable off-the-shelf solutions for demanding applications.
TP310S Seamless Pipe Application: 3" thick-walled TP310S seamless pipes are widely used in heat treatment furnace tubes, petrochemical cracking furnaces, heat exchangers, high-temperature flue gas pipelines, and combustion systems. Their exceptional heat and oxidation resistance enables distributors to effortlessly meet high-temperature/high-pressure transportation requirements when stocking for refinery, chemical, and energy clients.
