Industry Applications
• Petrochemical & Chemical Processing: Highly corrosion-resistant austenitic stainless steel fittings engineered for aggressive acidic and alkaline fluid networks.
• Power Generation & Nuclear Plants: High-integrity heavy-wall (Sch 160) fittings designed to withstand extreme high-temperature and high-pressure steam environments.
• Oil & Gas Refineries: Precision-machined fittings ensuring leak-proof connections in complex refinery processing lines.
• LNG (Liquefied Natural Gas) Facilities: Cryogenic-grade stainless steel fittings maintaining structural stability and impact toughness in sub-zero operational conditions.
• Desalination & Water Treatment: Durable, rust-proof components providing long-lasting performance in highly saline offshore and onshore environments.

Commercial Terms & Packaging
Professional Packaging Logistics
• Bevel Protection: All butt-weld fitting ends are fitted with heavy-duty plastic caps to prevent impact damage to the machined bevels.
• Seaworthy Wooden Crates: Smaller forged fittings and standard butt-weld components are sealed in high-strength, fumigated wooden cases to prevent surface scratches and marine corrosion.
• Steel Cradles & Pallets: Large-diameter and heavy-wall (Sch 160) fittings are secured with steel strappings on heavy-duty pallets to ensure safe forklift handling and zero transit movement.

Commercial Terms
• Trade Terms: FOB, CFR, CIF, EXW, FCA.
• Payment Terms: T/T (Telegraphic Transfer), Irrevocable L/C at sight.
• Standard Lead Time: 20 – 40 working days depending on order volume and custom fabrication requirements.
• Quality Documentation: EN 10204 3.1 Material Test Certificate (MTC) provided with every shipment. Third-Party Inspection (SGS, TUV, BV) is accepted.

Frequently Asked Questions (FAQ)
Q: What is the primary difference between ASME B16.9 butt-weld and ASME B16.11 forged fittings?
A: ASME B16.9 butt-weld fittings are welded directly to the pipe ends, making them ideal for large-diameter, high-pressure, and permanent pipework. ASME B16.11 forged fittings are either socket-welded or threaded, typically used for smaller diameter piping systems (usually NPS 4 and under) where rapid assembly or high-pressure ratings (up to 9000#) are required.
Q: Can you manufacture stainless steel pipe fittings with heavy wall thicknesses like Sch 160?
A: Yes. We specialize in heavy-wall stainless steel fabrication. We maintain a robust inventory of raw materials to produce high-performance butt-weld elbows, tees, and reducers up to Sch 160 and XXS for severe industrial applications.
Q: Do your material grades comply with international equivalent standards?
A: Absolutely. Alongside standard ASTM specifications (like WP304L/WP316L), we provide materials that meet international equivalents, such as the Russian GOST standard 12X18H10T (equivalent to ASTM 321), ensuring seamless integration into global projects.
Q: What quality control tests are performed on your fittings?
A: We enforce a strict zero-defect policy. Our non-destructive testing (NDT) includes 100% Visual and Dimensional Inspection, Radiographic Testing (RT) for welded seams, Ultrasonic Testing (UT), and Dye Penetrant Testing (PT) to guarantee the structural integrity of every fitting.
Q: Do you support custom dimensions or non-standard fittings?
A: Yes, our engineering team provides tailored manufacturing solutions. We can produce custom radii elbows, specialized reducing tees, and non-standard wall thicknesses based on your specific project blueprints and technical drawings.
