Durable 90° Stainless Steel Elbow for Sanitary Piping Systems

Core Definition & Function
Product Type: Pipe Fitting - Elbow

Angle: 90 Degrees - Ingeniously crafted to redefine pipeline direction with flawless accuracy at a perfect 90-degree angle, offering unmatched precision and reliability.

Connection Method: Butt Weld


Key Material Properties
Base Material: Austenitic Stainless Steel, prominently featuring:
AISI 304 / 304L (1.4301 / 1.4307): This versatile, all-purpose grade shines with exceptional corrosion resistance and superior formability. Perfectly suited for most non-severe corrosive settings, including industries such as food, beverage, dairy, and pharmaceuticals (non-sterile).

AISI 316 / 316L (1.4401 / 1.4404): Enhanced with molybdenum, delivering unparalleled corrosion resistance, effectively combating chlorides and pitting. The favored selection for pharmaceutical (notably WFI, Pure Steam), biotechnology, high-salinity, aggressive CIP/SIP chemicals, and marine sectors.

Material Compliance: Conforms to esteemed standards such as ASTM A270 (Seamless and Welded Austenitic Stainless Steel Sanitary Tubing), DIN 11850, ISO 2037, 3-A SSI, and more. Material Certificates (MTC) are available for added assurance.


Sanitary Design Features
Surface Finish:
Product Contact Surfaces: Utilize top-tier mechanical polishing or electropolishing techniques, ensuring optimal cleanliness with each contact.

Ra Value: Typically Ra ≤ 0.8 µm (32 µin) or even finer (e.g., Ra ≤ 0.5 µm / 20 µin, Ra ≤ 0.4 µm / 15 µin). This splendid mirror-finish reduces microbial adherence and product retention, facilitating thorough CIP/SIP cleaning.

Non-Contact Surfaces: Finished with a sophisticated satin or brushed look, meeting essential hygiene protocols.

Structural Design:
Seamless or Welded & Re-worked: Expertly crafted using precision techniques like mandrel bending, spinning, or welding + re-forming, ensuring continuous and smooth internal contours. Internally finished welded elbows match the pristine smoothness of the parent material.

Precise Centerline Radius (R): Options include 1.0D, 1.5D, or 2.0D (D = Nominal Diameter). Larger radii (1.5D, 2.0D) dramatically reduce flow resistance, erosion, and enhance drainability and cleanability. Compliant with R-values dictated by DIN 11850, ISO 2037, and SMS standards.

Zero Dead Space: The impeccably smooth internal geometry eradicates crevices and challenging-to-clean sections- vital for maintaining immaculate sanitary conditions in fittings.

Dimensional Accuracy: Crafted with high-precision manufacturing for an exact fit with straight tubing, facilitating seamless automated welding and ensuring system integrity. Adheres to dimensional tolerances per the relevant standards (DIN 11850, ISO 2037, SMS).


Connection Method (Welding)
Weld Preparation: Equipped with meticulously square-cut, deburred faces, guaranteeing precise alignment and minimal gap/offset with mating pipe (within standard allowances).

Welding Process: Automated Orbital TIG/GTAW welding is highly recommended. This sophisticated process offers:
High Purity: Experience unparalleled purity with our advanced inert gas shielding technique, expertly designed to prevent oxidation. This ensures each weld is impeccably clean and flawless, reflecting the superior craftsmanship behind every connection.

Consistency: Our state-of-the-art automation technology guarantees uniform, high-quality and repeatable welds every single time, offering you peace of mind with reliable performance.

Smooth Internal Weld Bead: Enjoy a seamless or virtually seamless internal weld profile, made possible by internal purge gas shielding or precise post-weld treatment. This ensures impeccable hygiene and optimal performance, meeting the highest standards of cleanliness effortlessly.

High Strength & Seal Integrity: The weld produces an exceptionally strong, leak-proof, and durable metallurgical bond, providing unwavering performance and reliability across all applications.

Post-Weld Treatment (Optional but Recommended): Elevate the durability and aesthetic of weld zones with this step, achieving a mirror-like polished finish that enhances both appearance and lifespan.Surface Finishing: Post-weld zones may be electropolished or mechanically polished, restoring and even enhancing the surface finish and corrosion resistance. This process ensures the elimination of micro-imperfections, matching or surpassing the parent material's quality.



Primary Application Areas
