Welding Capability & Process Range:<\/h2>\n\n\n\n

Material Coverage:<\/h3>\n\n\n\n

We manufacture Duplex Stainless Steel elbow products using Duplex 2205, Super Duplex 2507, S31803, S32205, and other corrosion-resistant alloy grades. In addition to duplex materials, our facility also supports carbon steel and austenitic stainless steel fabrication for mixed-material piping systems. Wall thickness capability ranges from 2.0 mm to 60 mm depending on pressure ratings and application requirements.<\/p>\n\n\n\n

Welding Methods:<\/h3>\n\n\n\n

Our production facility supports TIG, MIG\/MAG, SAW, orbital welding, and automated pipe welding processes. TIG welding is widely used for precision Duplex Stainless Steel elbow fabrication to achieve stable root penetration and controlled heat input. MIG welding improves efficiency for medium-wall piping assemblies, while SAW is suitable for heavy-wall industrial elbows requiring high-strength weld penetration and stable metallurgical properties.<\/p>\n\n\n\n

Tube Bending Capability:<\/h3>\n\n\n\n

Integrated CNC pipe bending equipment enables customized Duplex Stainless Steel elbow production with reduced weld seams and optimized flow performance. Supported pipe diameters range from \u00d821 mm to \u00d8820 mm with wall thickness from 2.0 mm to 30 mm. Minimum bending radius reaches 1.5D, while bending angle tolerance is controlled within \u00b10.2\u00b0, ensuring accurate fit-up and reduced installation adjustment during field assembly.<\/p>\n\n\n\n

Quality Assurance System:<\/h2>\n\n\n\n

Process Control:<\/h3>\n\n\n\n

All Duplex Stainless Steel elbow production follows approved WPS\/PQR procedures with strict heat input control and welding parameter monitoring to maintain proper ferrite-austenite balance. Welding consumables are stored under controlled environmental conditions with full batch traceability.<\/p>\n\n\n\n

Non-Destructive Testing:<\/h3>\n\n\n\n

VT, PT, MT, UT, and RT inspections are available according to customer specifications and international pipeline standards. Duplex Stainless Steel elbow products commonly undergo PT inspection for surface crack detection and UT or RT examination for pressure-service weld verification.<\/p>\n\n\n\n

Dimensional Inspection:<\/h3>\n\n\n\n

CMM systems, laser measurement equipment, and pipe geometry inspection tools are used to verify angle precision, wall thickness, concentricity, and dimensional tolerances. Each Duplex Stainless Steel elbow can be identified with weld seam numbering and QR-code traceability systems. Material certificates, PMI reports, ferrite testing records, NDT reports, hydrostatic test reports, and welding documentation are available with shipment.<\/p>\n\n\n\n

Delivery Capability & Response Speed:<\/h2>\n\n\n\n

Production Capacity:<\/h3>\n\n\n\n

Our fabrication facility maintains monthly output exceeding 100 tons of Duplex Stainless Steel elbow products and corrosion-resistant piping assemblies. Standard production lead time is typically 2\u20134 weeks depending on diameter size, material grade, and inspection requirements.<\/p>\n\n\n\n

Fast Response:<\/h3>\n\n\n\n

For prototype and small-batch Duplex Stainless Steel elbow projects, we provide rapid sample production within 3\u20137 days. Expedited manufacturing schedules are available for offshore shutdown projects, emergency pipeline maintenance, and urgent industrial procurement requirements.<\/p>\n\n\n\n

Production Management:<\/h3>\n\n\n\n

Integrated ERP and MES systems manage procurement, fabrication, inspection, machining, and logistics processes in real time. This ensures stable workflow management, transparent scheduling, and reliable on-time delivery for recurring Duplex Stainless Steel elbow supply contracts.<\/p>\n\n\n\n

Customer Case for Duplex Stainless Steel elbow:<\/h2>\n\n\n\n

An offshore engineering contractor in Southeast Asia required Super Duplex Stainless Steel elbow assemblies for seawater cooling pipeline systems operating in high-corrosion marine environments. The project demanded strict ferrite control, full PMI verification, and complete RT inspection for all pressure welds. After evaluating our duplex welding qualifications, inspection capabilities, and sample weld performance, the customer selected our factory as a qualified long-term supplier. By optimizing welding sequences and CNC bending configurations, we reduced heat distortion and improved flow transition quality. According to customer feedback, the delivered Duplex Stainless Steel elbow products demonstrated stable corrosion resistance, reliable dimensional consistency, and excellent weld integrity, helping shorten offshore installation time and reduce maintenance risks.<\/p>\n\n\n\n
