Core Definition & Function
Product Type: Pipe Fitting - Elbow
Angle: 45 Degrees - Designed to change pipeline direction by 45 degrees.
Connection Method:Butt Weld
Key Material Properties
Base Material:Austenitic Stainless Steel, primarily:
AISI 304 / 304L (1.4301 / 1.4307):** General-purpose grade offering excellent corrosion resistance and formability. Suitable for most non-extreme corrosive environments in food, beverage, dairy, and pharmaceutical (non-sterile) applications.
AISI 316 / 316L (1.4401 / 1.4404): Molybdenum-enhanced for superior corrosion resistance, particularly against chlorides and pitting.Preferred for pharmaceutical (especially WFI, Pure Steam), biotechnology, high-salinity or aggressive CIP/SIP chemicals, and marine applications.
Material Compliance: Conforms to relevant standards such as ASTM A270 (Seamless and Welded Austenitic Stainless Steel Sanitary Tubing), DIN 11850, ISO 2037, 3-A SSI. Material Certificates (MTC) available.
Sanitary Design Features
Surface Finish:
Product Contact Surfaces:High-grade mechanical polishing or electropolishing.
Ra Value: Typically Ra ≤ **0.8 µm** (32 µin) or finer (e.g., Ra ≤ 0.5 µm / 20 µin, Ra ≤ 0.4 µm / 15 µin). Mirror-like finish minimizes microbial adhesion and product retention, facilitating thorough cleaning (CIP/SIP).
Non-Contact Surfaces: Satin or brushed finish meeting basic hygiene requirements.
Structural Design:
Seamless or Welded & Re-worked:** Manufactured via precision processes (e.g., mandrel bending, spinning, or welding + re-forming) ensuring smooth, continuous internal contours. Welded elbows undergo internal finishing to match parent material smoothness.
Precise Centerline Radius (R): Typically 1.0D, 1.5D, or 2.0D (D = Nominal Diameter). Larger radii (1.5D, 2.0D) significantly reduce flow resistance (pressure drop), erosion, and enhance drainability/cleanability. Compliant with R-values specified in DIN 11850, ISO 2037, SMS standards.
Zero Dead Space: Smooth internal geometry **eliminates crevices and hard-to-clean areas** - a fundamental requirement for sanitary fittings.
Dimensional Accuracy: High-precision manufacturing ensures **exact fit** with straight tubing for seamless automated welding and system integrity. Complies with dimensional tolerances per relevant standards (DIN 11850, ISO 2037, SMS).
Connection Method (Welding)
Weld Preparation:Ends feature square-cut, deburred faces for precise alignment and minimal gap/offset with mating pipe (within standard allowances).
Welding Process:Automated Orbital TIG/GTAW welding is strongly recommended. This process delivers:
High Purity:*Inert gas shielding prevents oxidation, ensuring clean welds.
Consistency: Automation guarantees uniform, repeatable weld quality.
Smooth Internal Weld Bead: Produces a flush or near-flush internal weld profile, achievable via internal purge gas shielding or post-weld treatment.
High Strength & Seal Integrity:Creates a permanent, leak-tight metallurgical bond.
Post-Weld Treatment (Optional but Recommended): Weld zones may undergo electropolishing or mechanical polishing to restore surface finish and corrosion resistance equivalent to the parent material, eliminating potential micro-imperfections.
Primary Application Areas
Food & Beverage Industry: Milk, juice, beer, soft drinks, sauces, edible oil processing lines.
Pharmaceutical & Biotechnology:Purified Water (PW), Water-for-Injection (WFI), Clean Steam (CS), process gases, media, biologics, API manufacturing.
Dairy Industry.
Cosmetics Industry.
Fine Chemicals (High Purity).
Any fluid handling system requiring high cleanliness and sterility assurance.
Key Advantages Summary
Exceptional Hygienic Performance: High surface finish, dead-space-free design, suitable for thorough CIP/SIP cleaning and sterilization.
High Seal Integrity & Reliability: Welded connection provides a permanent, leak-proof seal.
Superior Corrosion Resistance:High-quality stainless steel (esp. 316L) withstands corrosive media and cleaning agents.
Smooth Flow Path: Precise radius and high finish ensure laminar flow, minimizing pressure drop, turbulence, and product degradation/retention.
Easy Cleaning & Maintenance:Simple structure, no moving parts, smooth surfaces facilitate cleaning.
High Strength & Durability:Stainless steel construction and welded joints ensure long service life.
Compatible with Automated Production:Ideal for integration into automated orbital welding systems, enhancing efficiency and consistency.
Key Specifications (To be specified per item)
Nominal Diameter (DN/NPS):e.g., DN 15 - DN 150 (½" - 6") or other common sizes.
Centerline Radius (R): e.g., 1.0D, 1.5D, 2.0D (D must correspond to specific size).
Pressure Rating: Typically determined by system design pressure; weld connection inherently offers high strength.
Temperature Range: Dictated by material; generally suitable for -20°C to +200°C (higher intermittently), accommodating CIP/SIP needs.
Applicable Standards: e.g., DIN 11850, ISO 2037, SMS, ASME BPE, 3-A.
In Summary:The Sanitary Stainless Steel 45° Welding Elbow is a precision-engineered pipe fitting designed for industries demanding the highest hygienic standards. Manufactured from compliant stainless steel (304L/316L), featuring a high-polish finish (Ra ≤ 0.8µm), dead-space-free design, and precise bend radii (typically 1.5D), it utilizes clean orbital welding for permanent, leak-tight connections. Its core value lies in delivering exceptional hygiene, cleanability, reliable sealing, and compliance with rigorous certifications (3-A, EHEDG, FDA, GMP), making it an essential component for reliable, aseptic 45° directional changes in critical fluid systems within food, pharmaceutical, and bio-processing sectors.
