Non-standard Flange
SDFL
The 304 stainless steel sanitary grade quick-loading clamp joint is a hygienic connection component for process piping that is opened, cleaned and re-sealed on a regular basis. Its clamp-style union joins sanitary tubing, valves, pumps and process equipment without welding at the joint face, shortening line changeover and maintenance time in food, beverage, pharmaceutical and biotech processing. It is manufactured in-house by Shangdian Flange Pipe Fittings Co., Ltd. with standard material verification and surface finishing discipline.
The quick-loading clamp joint is produced from 304 stainless steel with a smooth, cleanable bore and a sanitary-grade surface finish suited to hygienic duty. The clamp-style body supports rapid assembly and disassembly with a standard clamp, simplifying cleaning between runs and line modification. Non-standard dimensions and connection configurations are manufactured against customer drawings and project requirements, matching existing line layouts without redesign.

The standard material is 304 stainless steel, selected for corrosion resistance and cleanability in hygienic service. For processes with higher chloride or temperature demands, 304L, 316L and related stainless grades are also supplied, and custom special alloy grades are available upon request. Every batch is verified by 100% PMI spectral inspection with composition traceable to the mill melt number, for a documented chain from melt to finished part.
Each clamp joint moves through a controlled in-house process: raw material PMI spectral inspection, closed-die hot forging on a hydraulic forming press, solution heat treatment on a continuous line, precision CNC machining on 5-axis machining centers, semi-finishing dimensional and surface inspection, and surface finishing by pickling and passivation, mechanical finishing or electrolytic polishing. Final dimensional checks, non-destructive testing where specified and surface inspection complete the sequence before export packaging.

Quality control starts with material: 100% PMI spectral analysis per batch, fully traceable to the mill melt number. Dimensional control uses high-precision instruments to hold tolerance compliance with the applicable international standards. Penetrant, ultrasonic and radiographic tests are available on request, and sanitary-grade electrolytic polishing is followed by a cleanliness test. Third-party inspection witnessed by SGS, BV or TUV is supported for independent verification before shipment.
The clamp joint can be manufactured to customer drawings, samples or project specifications. Non-standard dimensions, connection configurations, special materials and sanitary-grade surface treatments can be specified. Engineering support covers working-condition analysis, material selection and piping solution design, and laser marking is available for logos, part numbers, batch numbers or project identification. OEM and ODM services support consistent private-label supply.
Clamp joints are packed in export wooden cases with sealing faces protected by protective caps, 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 consignment, so clearance and incoming inspection can proceed without extra requests.
The 304 stainless steel sanitary clamp joint connects hygienic process lines in the food, beverage, pharmaceutical and biotech industries, joining tubing, valves, pumps and equipment with a clamp-style union that supports rapid assembly, disassembly and cleaning.
