Angle: 45 Degrees - Expertly crafted to offer a seamless 45-degree pivot in pipeline orientation, guaranteeing unmatched precision and efficiency.
Connection Method: Butt Weld
Key Material Properties
Base Material: Austenitic Stainless Steel, featuring prominently:
AISI 304 / 304L (1.4301 / 1.4307): This versatile, go-to grade ensures remarkable corrosion resistance and superb formability, perfect for general-purpose use in non-extreme environments such as food, beverage, dairy, and non-sterile pharmaceutical applications.
AISI 316 / 316L (1.4401 / 1.4404): Enriched with molybdenum, this variant offers exceptional resistance to corrosion, particularly against chlorides and pitting, making it the ideal choice for demanding pharmaceutical (WFI, Pure Steam), biotechnology, high-salinity, aggressive CIP/SIP chemicals, and marine settings.
Material Compliance: Complies with esteemed standards like ASTM A270, DIN 11850, ISO 2037, and 3-A SSI, with Material Certificates (MTC) available for quality assurance.
Sanitary Design Features
Surface Finish:
Product Contact Surfaces: Utilize top-tier mechanical or electropolishing methods to achieve superior cleanliness and hygiene.
Ra Value: Typically Ra ≤ 0.8 µm (32 µin) or even finer options (e.g., Ra ≤ 0.5 µm / 20 µin, Ra ≤ 0.4 µm / 15 µin). This highly reflective finish minimizes microbial adhesion and product retention, promoting thorough CIP/SIP cleaning.
Non-Contact Surfaces: Boasts a satin or brushed finish that aligns with core hygiene standards, ensuring cleanliness.
Structural Design:
Seamless or Welded & Re-worked: Crafted through precision techniques like mandrel bending, spinning, or welding + re-forming to ensure smooth, consistent internal contours. Welded elbows are internally polished to match the parent material's smoothness.
Precise Centerline Radius (R): Typically 1.0D, 1.5D, or 2.0D (D = Nominal Diameter), with larger radii (1.5D, 2.0D) effectively minimizing flow resistance, erosion, and enhancing drainability/cleanability. Adheres to DIN 11850, ISO 2037, SMS standards for R-values.
Zero Dead Space: The internal design's smooth geometry eradicates crevices and difficult-to-clean spots, a crucial aspect for maintaining sanitary conditions in fittings.
Dimensional Accuracy: Precision manufacturing guarantees a flawless fit with straight tubing, facilitating seamless automated welding and system integrity. Conforms to dimensional tolerances per DIN 11850, ISO 2037, SMS standards.
Connection Method (Welding)
Weld Preparation: Ends are expertly square-cut and deburred to ensure precise alignment and minimal gap/offset with connecting pipes, adhering to standard allowances.
Welding Process: Automated Orbital TIG/GTAW welding is highly recommended, offering:
High Purity: *Harness the power of inert gas shielding to expertly prevent oxidation, resulting in impeccably clean, flawless welds that speak volumes about quality and precision.
Consistency: Automation is your guarantee of uniform and repeatable weld quality, ensuring excellence with each and every weld.
Smooth Internal Weld Bead: Experience the epitome of seamless or nearly seamless internal weld profiles. Achieved effortlessly through advanced internal purge gas shielding or meticulous post-weld treatment, this ensures unparalleled hygiene and superior performance.
High Strength & Seal Integrity: Forge a robust, leak-proof, and enduring metallurgical bond with every weld, offering uncompromised performance and steadfast reliability.
Post-Weld Treatment (Optional but Recommended): Elevate the durability and aesthetics of weld zones through this additional step, achieving a brilliant, polished finish.: Through electropolishing or mechanical polishing, weld zones not only regain but also surpass the original surface finish and corrosion resistance of the parent material, effectively eliminating micro-imperfections.
Primary Application Areas
Food & Beverage Industry: Ideal for processing milk, juice, beer, soft drinks, sauces, and edible oils, ensuring quality and cleanliness are never compromised.
Pharmaceutical & Biotechnology: Perfect for applications including Purified Water (PW), Water-for-Injection (WFI), Clean Steam (CS), process gases, media, biologics, and API manufacturing, ensuring purity and sterility.
Dairy Industry: Delivering top-tier cleanliness and reliability in dairy processing operations.
Cosmetics Industry: Uphold stringent hygiene and product integrity standards in cosmetic manufacturing processes.
Fine Chemicals (High Purity): Safeguard purity and compliance in critical chemical processes.
Any fluid handling system requiring high cleanliness and sterility assurance: Designed for any application where uncompromising cleanliness and sterility are paramount.
Key Advantages Summary

High Strength & Durability: The sturdy stainless steel build and welded joints ensure a prolonged lifespan, even under rigorous conditions.
Compatible with Automated Production: Engineered for seamless integration into automated orbital welding systems, it boosts production efficiency and consistency.
Key Specifications (To be specified per item)
Nominal Diameter (DN/NPS): Customizable to cater to common sizes, ranging from DN 15 - DN 150 (½" - 6") or tailored to meet specific requirements.
Centerline Radius (R): Available in options like 1.0D, 1.5D, 2.0D, ensuring precise application specifications are met.
Pressure Rating: Typically defined by system design pressure, the robust weld connection inherently provides substantial strength.
Temperature Range: Material-dependent, generally accommodating temperatures from -20°C to +200°C, with the capability of handling even higher temperatures intermittently for CIP/SIP processes.
Applicable Standards: Meets and exceeds standards such as DIN 11850, ISO 2037, SMS, ASME BPE, and 3-A, ensuring global applicability and compliance.
