This sanitary elbow complies with multiple industrial and sanitary standards, including ANSI B16.9 / ASME B16.9, MSS-SP-83, EN 10253, DIN 2605, JIS B2311, JIS B2312, ISO 4144, ISO 1127 and BS 3799. For hygienic application scenarios, products can be produced in accordance with corresponding sanitary standards according to project requirements.
The standard sanitary elbow adopts 304 or 316L austenitic stainless steel, which has stable chemical properties and is not easy to precipitate harmful substances in contact with food and pharmaceutical media. The material has resistance to corrosion from weak acid, weak alkali and water-based media, adapting to conventional cleaning and disinfection procedures. For special corrosive media or high-temperature working conditions, other material grades listed in the parameter table are available.
The elbow is formed by push-forming technology, which ensures uniform wall thickness and smooth internal and external transitions. Welds are treated with smoothing process to eliminate protruding weld beads, avoiding material accumulation and bacterial growth points. The forming process maintains the original corrosion resistance of the base material to the maximum extent.
Both inner and outer surfaces of the elbow undergo mirror polishing treatment. The polishing process reduces surface roughness, lowers fluid flow resistance, and reduces material residue on the pipe wall. This surface treatment supports CIP (Clean-in-Place) and SIP (Sterilization-in-Place) procedures, meeting the hygienic management requirements of production lines. Additional surface treatment options include grinding, sandblasting, spray painting, galvanizing and marking for industrial application scenarios.
This sanitary elbow is suitable for fluid transmission pipelines in food and beverage production, including dairy processing, beverage filling, brewing, edible oil processing and catering supply systems. It can be used for conveying water, milk, juice, edible oil and other food-grade media within the applicable temperature range.
In the pharmaceutical and fine chemical industries, the elbow can be applied to clean fluid transmission systems, pharmaceutical ingredient pipelines, and water treatment systems for production workshops. Its smooth surface reduces cross-contamination risk and supports regular disinfection operations. For special industrial scenarios such as petrochemical industry, waste gas systems, power plants, shipbuilding and water treatment, industrial-grade elbows with corresponding material and pressure ratings are available.
Each batch of products undergoes dimensional inspection, surface finish testing, wall thickness verification and pressure tightness test before delivery. The production process complies with ISO 9001 quality management system, ISO 14001 environmental management system and ISO 45001 occupational health and safety management system. Products support third-party inspection by authorized agencies according to customer requirements.
Regular specifications of sanitary elbows are kept in stock for fast delivery. For bulk orders, production scheduling is arranged according to order quantity and specification complexity. Factory direct supply structure eliminates intermediate links. Products support bulk full-container export, and packaging can be customized according to transportation requirements.
For commercial procurement projects with specific requirements, the following customization services are available:
Custom dimensions including non-standard outer diameter, wall thickness and elbow angle
Optional connection types: welding, clamp, thread and other sanitary connection forms
Adjustable surface finish levels according to hygienic grade requirements
Custom material grades for special media and temperature working conditions
Custom packaging and marking services for project identification
This sanitary elbow adopts internal and external mirror polishing treatment as standard. Specific surface roughness values can be provided according to customer requirements, and different finish levels are available via customization.
This elbow complies with ANSI B16.9, EN 10253, ISO 1127 and other international industrial pipe fitting standards, and can be produced according to corresponding sanitary standards for hygienic projects.
The standard 304/316L stainless steel material and mirror polished surface are designed for hygienic fluid scenarios including food and beverage transmission. For specific food contact certification requirements, please confirm with the sales team before ordering.
Yes, non-standard dimensions, various connection types and special material grades can be customized according to customer drawings or project requirements.
The elbow, pipe and flange should use the same nominal diameter, wall-thickness series and dimensional standard. The connection ends must also be compatible, such as welded, clamped or threaded connections. Matching these specifications helps prevent installation misalignment and sealing problems.
Yes. Sanitary elbows can be produced according to customer drawings or piping requirements. Customization may include the outside diameter, wall thickness, bend radius, connection type and surface finish. Please provide a drawing or complete dimensional information for evaluation.
Yes. Material certificates and relevant inspection reports can be provided. The material grade and key dimensions can be checked before shipment to help ensure compatibility with sanitary, pharmaceutical, food-processing or other clean-piping applications.
Yes. Matching flanges, elbows, tees, reducers, crosses and end caps can be produced according to the same piping standard. Purchasing the components from one supplier can reduce dimensional differences and improve installation compatibility.
