The Sanitary Stainless Steel BPE 90° Elbow and Tube is suitable for process systems in the biopharmaceutical, biotechnology, pharmaceutical, food & beverage, dairy, semiconductor, cosmetics, and other high-purity industries. It can be supplied for applications requiring ASME BPE, 3-A, EHEDG, and FDA-related hygienic requirements, subject to the selected material, finish, configuration, and applicable documentation.
AVM provides 45°, 90°, and 180° configurations, with butt weld and Tri-Clamp connection options for different sanitary piping layouts.
AVM sanitary stainless steel elbows are available in 45°, 90°, and 180° configurations. The 45° option is used where a gradual change in pipeline direction is required, while the 90° elbow is suitable for perpendicular pipe connections. The 180° return bend allows the pipeline to reverse direction within a compact process layout.
The 90° elbow is available in 1.0D short-radius and 1.5D long-radius configurations, allowing engineers to select the appropriate geometry according to available installation space and piping requirements.
The fitting is available with butt weld and Tri-Clamp connections. Butt weld connections provide a permanent hygienic joint for fixed process piping, while Tri-Clamp connections allow faster installation, disassembly, inspection, and maintenance.
Connection selection should be based on the existing tube system, applicable piping standard, installation method, and maintenance requirements.
The sanitary elbow and tube system covers 1/2" to 6" OD tube sizes. This range allows the fittings to be integrated into different process piping configurations, from smaller high-purity lines to larger fluid transfer systems.
AVM sanitary elbows are manufactured from ASTM A270 TP304L or TP316L stainless steel. TP304L is suitable for many general sanitary processing applications, while TP316L provides improved corrosion resistance for more demanding process environments and high-purity applications.
The material selection should consider the process medium, temperature, corrosion conditions, cleanliness requirements, and applicable project specifications.
The internal bore is manufactured with a smooth surface designed to reduce product retention and provide a cleaner flow path. The standard mechanical polishing option achieves Ra ≤ 0.51 μm (20 μin), while electropolished versions can achieve Ra ≤ 0.38 μm (15 μin).
A controlled surface finish is particularly important in applications where residual product, microbial contamination, or difficult cleaning can affect production quality.
The internal structure is designed to minimize crevices and areas where process media can remain after draining. This supports more effective cleaning and helps reduce residual material during process changeover.
The design is suitable for systems using CIP and SIP procedures, subject to the complete system configuration and operating conditions.
The Sanitary Stainless Steel BPE 90° Elbow and Tube is designed for high-purity process piping applications with reference to ASME BPE requirements. Material selection, surface finish, dimensions, connections, and fabrication requirements can be specified according to the requirements of the project.
The sanitary design is suitable for hygienic processing systems where 3-A and EHEDG hygienic design principles are required. Smooth internal surfaces, reduced product retention, and drainable construction support applications where cleanability and contamination control are important.
The fitting can be configured for applications requiring FDA-related material compliance, subject to the selected sealing materials, product-contact materials, and applicable documentation. Buyers should specify the required FDA documentation or compliance requirements before ordering.
For projects requiring formal certification or specific compliance documentation, AVM can confirm the applicable ASME BPE, 3-A, EHEDG, and FDA-related requirements according to the actual product configuration.
The sanitary elbow is used in high-purity process piping for pharmaceutical and biopharmaceutical production, including fluid transfer, formulation systems, purified water distribution, process equipment connections, and other hygienic applications.
Typical applications include fermentation systems, bioreactor piping, clean fluid distribution, process vessels, sampling systems, and other biotechnology equipment where contamination control is important.
The fitting can be installed in sanitary piping for dairy, beverage, liquid food, juice, brewing, and other food-processing systems where smooth surfaces and effective cleaning are required.
The elbow is suitable for high-purity fluid piping in semiconductor-related applications where controlled surface finish, stainless steel material quality, and low-retention flow paths are important.
The fitting can also be used in clean utility and high-purity fluid systems where hygienic connections and controlled internal surfaces are required.

Buyers should select TP304L or TP316L according to the process medium and corrosion conditions. For more demanding high-purity or corrosive applications, TP316L is commonly considered where its enhanced corrosion resistance is required.
The tube OD must match the existing process piping system. Buyers should confirm the required size before ordering to avoid installation problems or additional transition fittings.
Butt weld and Tri-Clamp connections serve different installation requirements. Butt weld is suitable for permanent piping systems, while Tri-Clamp is more convenient where equipment needs to be frequently disconnected for inspection or maintenance.
Surface finish should be selected according to the actual cleanliness requirements of the process. Mechanical polishing can meet many sanitary applications, while electropolishing is suitable for projects requiring a lower surface roughness and enhanced high-purity surface condition.
For pharmaceutical, biotechnology, semiconductor, and other regulated projects, buyers should confirm whether the project requires ASME BPE, 3-A, EHEDG, FDA-related compliance, material certificates, or specific inspection documentation before production.
AVM provides Sanitary Stainless Steel BPE 90° Elbow and Tube for hygienic and high-purity process piping systems. Products can be configured according to material grade, angle, radius, tube size, connection type, surface finish, and applicable sanitary requirements.
For projects with strict documentation requirements, AVM can confirm the applicable material and compliance documents according to the final product configuration. This allows buyers to define technical requirements before production rather than modifying the piping specification after delivery.
AVM Sanitary Stainless Steel BPE 90° Elbow and Tube is available in ASTM A270 TP304L and TP316L stainless steel. TP304L is suitable for general hygienic applications, while TP316L is preferred for applications requiring higher corrosion resistance or more demanding high-purity process conditions.
The sanitary elbow is available with mechanically polished or electropolished internal surfaces. Mechanical polishing can achieve Ra ≤ 0.51 μm (20 μin), while electropolishing can achieve Ra ≤ 0.38 μm (15 μin). The appropriate finish can be selected according to the cleanliness and surface roughness requirements of the process system.
AVM supplies sanitary BPE elbows and tubes in sizes from 1/2" to 6" OD. Buyers should confirm the required tube outside diameter and applicable dimensional standard to ensure compatibility with the existing sanitary piping system.
Yes. The 90° sanitary elbow is available in 1.0D short-radius and 1.5D long-radius configurations. The appropriate radius can be selected according to pipeline layout, available installation space, and process requirements.
The product is available with butt weld and Tri-Clamp connections. Butt weld connections are suitable for permanent hygienic piping, while Tri-Clamp connections provide easier installation, disassembly, inspection, and maintenance.
