Threaded Fittings
SDFL
The 304/316L stainless steel threaded 90 degree elbow changes the direction of a piping run through a threaded connection, keeping installation weld-free and simplifying later disassembly for maintenance or reconfiguration. It is manufactured as a forged threaded fitting in line with ASME B16.11 dimensional requirements, and the size-stamped body makes specification checks straightforward during receiving inspection. Produced in-house by Shangdian Flange Pipe Fittings Co., Ltd., the threaded elbow is a practical stock item for maintenance, replacement and new line builds.
The threaded 90 degree elbow provides a 90-degree directional change with precision-machined threaded ends, so crews can connect schedule-matched pipe without welding equipment at the joint. The body is size-stamped for quick identification on site, and smooth machined surfaces support a clean installation. Non-standard dimensions and thread configurations can be manufactured against customer drawings and project requirements, matching existing systems without rework.

The threaded 90 degree elbow is available in 304 and 316L stainless steel, with 304L and related stainless grades supplied on request. Both material options are covered by the factory's standard verification: every batch receives 100% PMI spectral inspection, and the chemical composition is traceable to the original mill melt number. For industrial clients running aggressive media or chloride-bearing environments, the 316L stainless steel threaded elbow provides the added corrosion margin needed for longer service life.
Each threaded elbow passes through a controlled in-house sequence: raw material PMI spectral inspection, closed-die hot forging on a hydraulic forming press, solution heat treatment on a continuous line, and precision CNC machining on 5-axis machining centers with high-precision CNC lathes. Semi-finishing dimensional and surface inspection is followed by surface finishing, and final steps cover dimensional testing, non-destructive testing where specified and a surface defect check. With the full chain operated in-house, material records and process control stay under one roof from melt to finished elbow.

Quality control begins with material verification: 100% PMI spectral analysis per batch with full traceability to the mill melt number. Dimensional control uses high-precision inspection to hold tolerance compliance with the applicable international standards, and penetrant, ultrasonic and radiographic tests are available on request. Third-party inspection witnessed by SGS, BV or TUV is supported, giving business buyers an independent check before the elbow leaves the factory.
The threaded 90 degree elbow can be produced to customer drawings, samples or project specifications, including non-standard dimensions and thread configurations. Special materials can be specified for corrosion or temperature demands, and engineering support covers working-condition analysis, material selection and piping solution design. Laser marking is available for logos, part numbers, batch numbers or project identification, and OEM and ODM services support consistent private-label supply.
Threaded elbows are packed in export wooden cases with sealing surfaces and threads protected against transit damage, and each case carries custom shipping marks, batch numbers and material traceability marking. Shipping options include FCL and LCL sea freight, air freight and international express delivery. A full set of export documents, material test reports, certificates and packing lists accompanies every order, so the receiving team can clear customs and complete incoming inspection without additional requests.
The 304/316L stainless steel threaded 90 degree elbow is used wherever a piping run must change direction without welding, including maintenance and replacement work, utility lines and process piping where threaded connections are preferred for disassembly and reconfiguration.
