Core Definition & Function
Product Type: Pipe Fitting - Elbow
Angle: 45 Degrees - Expertly designed to seamlessly alter pipeline direction by a precise 45 degrees, facilitating efficient flow management.
Connection Method: Butt Weld
Key Material Properties
Base Material: Austenitic Stainless Steel, primarily:
AISI 304 / 304L (1.4301 / 1.4307):** A robust general-purpose grade offering outstanding corrosion resistance and formability. Perfectly suited for non-extreme corrosive environments, such as in food, beverage, dairy, and non-sterile pharmaceutical applications.
AISI 316 / 316L (1.4401 / 1.4404): Enhanced with molybdenum for superior defense against corrosion, especially in chloride-rich and pitting environments. Ideal for pharmaceutical applications (WFI, Pure Steam), biotechnology, high-salinity conditions, aggressive CIP/SIP chemicals, and marine use.
Material Compliance: Fully conforms to essential industry standards such as ASTM A270 for seamless and welded austenitic stainless steel sanitary tubing, along with DIN 11850, ISO 2037, and 3-A SSI. Material Certificates (MTC) are readily available for assurance.
Sanitary Design Features
Surface Finish:
Product Contact Surfaces: High-grade mechanical polishing or electropolishing ensures impeccable cleanliness.
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), creating a mirror-like finish that drastically minimizes microbial adhesion and product retention, thereby facilitating complete and efficient cleaning (CIP/SIP).
Non-Contact Surfaces: Features a satin or brushed finish that reliably meets basic hygiene standards.
Structural Design:
Seamless or Welded & Re-worked:** Crafted with precision processes such as mandrel bending, spinning, or welding plus re-forming, these elbows ensure smooth, continuous internal contours. Welded elbows undergo meticulous internal finishing to achieve smoothness that matches the parent material.
Precise Centerline Radius (R): Typically within 1.0D, 1.5D, or 2.0D (D = Nominal Diameter). Larger radii, such as 1.5D or 2.0D, substantially reduce flow resistance (pressure drop), minimize erosion, and significantly enhance drainability and cleanability. Compliant with R-values specified in standards like DIN 11850, ISO 2037, and SMS.
Zero Dead Space: The smooth internal geometry is meticulously engineered to eliminate crevices and hard-to-clean areas, a fundamental requirement for top-tier sanitary fittings.
Dimensional Accuracy: Precision manufacturing guarantees an exact fit with straight tubing, promoting seamless automated welding and preserving system integrity. Adheres strictly to dimensional tolerances outlined by relevant standards (DIN 11850, ISO 2037, SMS).
Connection Method (Welding)
Weld Preparation: Ends are expertly crafted with square-cut and deburred faces to ensure precise alignment and minimize gap/offset with the mating pipe, staying within standard allowances.
Welding Process: Automated Orbital TIG/GTAW welding is highly recommended for this product, offering:
High Purity: Inert gas shielding effectively prevents oxidation, resulting in exceptionally clean welds.
Consistency: Automation ensures uniform and repeatable weld quality, delivering reliable results every time.
Smooth Internal Weld Bead: Achieve a seamless, nearly flush internal weld profile that enhances your system's efficiency. This is accomplished through the innovative use of internal purge gas shielding or refined post-weld treatment, ensuring optimal performance.
High Strength & Seal Integrity: Forge a permanent, leak-tight metallurgical bond that stands the test of time, providing unparalleled strength and seal integrity for your systems.
Post-Weld Treatment (Optional but Recommended): Enhance the longevity and performance of your weld zones with this recommended finishing touch.: Elevate your weld zones by undergoing electropolishing or mechanical polishing. This process restores the surface finish and corrosion resistance to match the parent material, effectively eliminating micro-imperfections.
Primary Application Areas: Discover the versatility of this product across diverse industries.
Food & Beverage Industry: Perfect for milk, juice, beer, soft drinks, sauces, and edible oil processing lines, ensuring cleanliness and safety.
Pharmaceutical & Biotechnology: Ideal for Purified Water (PW), Water-for-Injection (WFI), Clean Steam (CS), process gases, media, biologics, and API manufacturing, guaranteeing high purity and reliability.
Dairy Industry: Tailored solutions for maintaining the highest hygiene standards in dairy production.
Cosmetics Industry: Ensure product purity and safety with impeccable standards.
Fine Chemicals (High Purity): Designed for high-purity applications, meeting rigorous industry demands.
Any fluid handling system requiring high cleanliness and sterility assurance: A critical component for systems demanding top-notch cleanability and sterility.
