S32750 Seamless Tube is a super duplex stainless steel. It combines the advantages of austenitic and ferritic grades, offering exceptional strength and outstanding corrosion resistance. This material excels in chloride-containing environments, particularly resisting pitting and crevice corrosion. S32750 is suitable for demanding industrial applications including offshore engineering, petrochemical processing, seawater desalination, and heat exchanger systems. SMLSCO's S32750 seamless tubes ensure long-term, stable equipment performance under harsh operating conditions.
- SMLSCO maintains over 200 tons of stainless steel seamless tube inventory (1/4"-2")
- Standard-sized products can be delivered within 2 weeks
- Our S32750 heat exchanger tubes undergo bright annealing (BA) to guarantee clean, residue-free inner walls
- All products undergo 100% eddy current testing (ET) and are certified to PED, ISO, and AD2000 standards
- We guarantee zero-defect delivery, making us your efficient and reliable sourcing partner
SMLSCO rigorously implements a "three-step inspection" process: raw material re-inspection, production process control, and 100% pre-shipment inspection. For heat exchanger tubes, we focus on dimensions, surface finish, and mechanical properties, complemented by PMI spectral analysis and eddy current testing. All SMLSCO inspection records are fully traceable. We provide detailed pre-shipment inspection photos or video documentation, ensuring every tube you receive fully complies with ASTM A789 standards.
To safeguard S32750 precision tubes during transit, we employ multi-layered protective packaging. Each tube is individually wrapped in bubble wrap or foam sleeves to prevent surface scratches. Plastic end caps are fitted to protect both ends of the tubes. Finally, all tubes are securely packed into sturdy plywood crates or strapped with steel bands onto wooden pallets to ensure safety and stability during ocean and land transportation.
A1: 6 meters is the most commonly stocked standard length, and we maintain substantial inventory. Additionally, to meet specific project requirements, SMLSCO offers precise custom cutting services. Please specify your exact length requirements and tolerance specifications when requesting a quote. We will provide the most cost-effective solution.
A2: S32750 is a super duplex stainless steel. Its core advantages include:
- Exceptionally high strength (nearly double that of 316L)
- Superior corrosion resistance, particularly in chloride-containing environments
- Significantly enhanced resistance to pitting and crevice corrosion compared to 316L
This makes it ideal for heat exchangers in demanding applications such as marine engineering, chemical processing, and desalination.
A3: Each S32750 tube is clearly marked with either spray-painted or stamped identification in accordance with ASTM A789 standards. The identification typically includes: the SMLSCO brand logo, the applicable standard (ASTM A789), the material grade (S32750), the specifications (OD x WT x L), and a unique heat treatment batch number (Heat No.).
