TP316/316L contains 2-3% Molybdenum, providing excellent resistance to pitting and crevice corrosion in high-chloride environments. The low-carbon 316L variant eliminates sensitization tendency in welded areas, making it ideal for rapid on-site splicing applications. The heavy-wall design combined with cold-drawing reinforcement ensures stable mechanical properties under high pressure and pulsating loads.
- Chemical injection lines
- Offshore platform hydraulic systems
- High-pressure heat exchangers
- Boiler feedwater circuits
- Industrial systems requiring high safety factors
Maintains large stock of 316/316L heavy-wall pipe covering full OD range from Sch60 to Sch160.
Global container loading ready within two weeks with support for mixed specifications in same container.
Bulk purchasing of raw materials lowers unit costs, enhancing distributor price competitiveness.
ISO + PED certified, saving time on repeated quality inspections and improving capital turnover efficiency.
Multi-pass cold drawing finishing process involves multiple cold draws with intermediate annealing and straightening. This advanced manufacturing technique controls dimensional tolerances to within ±0.05 mm, improves wall thickness uniformity by over 12%, and develops fine-grain structure that significantly increases compressive strength. The resulting mirror-finish inner wall reduces fluid resistance, providing safer operation for high-pressure systems.
Three-stage quality control process includes PMI for raw materials, in-process eddy current and ultrasonic testing, and 100% review of finished product hydro-test and dimensions. Each pipe is photographed and archived, with SGS/TÜV spot-check reports available upon request. Complete and traceable data ensures rapid quality acceptance.
