Advantages of Our Stainless steel pipe fittings
Superior Structural Strength & Lifespan
Our fittings undergo precision forging and heat treatment, providing high tensile strength and wear resistance. Compared to carbon steel, they maintain structural integrity much longer in corrosive media, effectively minimizing downtime risks and ensuring a service life of several decades.
Strict Standard Compliance & Seamless Fit
Our products strictly adhere to international standards such as ASTM, ANSI, DIN, and JIS. This ensures that dimensional tolerances, wall thickness, and bevel angles of every elbow, tee, or flange meet top-tier industry requirements, guaranteeing seamless compatibility and improving on-site welding or threading efficiency.
Multi-Stage Quality Inspection for Zero Defects
We implement a comprehensive quality control process, including 100% Positive Material Identification (PMI), hydrostatic testing, X-ray weld inspection, and ultrasonic testing. This rigorous flow ensures a defect-free interior, providing a reliable safety guarantee for high-stakes industries such as oil, chemicals, food, and pharmaceuticals.

FAQs
Do your fittings come with MTC to guarantee that the Nickel content in 316L meets standards?
Yes, all our fittings are accompanied by Material Test Certificates (MTC) according to EN 10204 3.1. We strictly control chemical composition to ensure the Nickel and Molybdenum content of 316L fully complies with ASTM A182 or A403 standards, and we welcome on-site PMI testing.
Which connection type do you recommend for high-pressure transmission systems?
For high-pressure or safety-critical conditions, we recommend Butt-weld or Socket Weld fittings. Butt-weld connections provide the maximum structural integrity and fatigue resistance, while high-pressure threaded fittings are suitable for small-bore instrumentation systems requiring periodic disassembly.
Are your elbows and tees solution-annealed during production?
Yes. After the forming process, all stainless steel fittings undergo rigorous solution annealing. This step eliminates processing stress, restores the austenitic microstructure, and enhances corrosion resistance, effectively preventing stress corrosion cracking during service.
Do you support hybrid customization of standards, such as DIN dimensions with ASTM materials?
Yes. We possess flexible production capabilities and can manufacture according to specific engineering drawings. Whether it’s non-standard wall thickness (e.g., Sch 160 or thicker), specialized angles, or cross-requirements of different international standards, we provide precise fabrication services.
How are pipe bevels and threads protected from damage or rust during long-term storage?
We provide full protection for all outgoing fittings: plastic caps are installed on butt-weld ends, and precision threads are coated with anti-rust oil and fitted with protective plugs. Furthermore, all fittings are packed in reinforced wooden crates or fumigation-free pallets to ensure they remain intact during long-term storage or sea freight.
