Description

Product details

Dairy and sanitary fittings are highly polished, crevice-free components engineered to meet strict hygiene standards. They prevent bacterial growth, withstand clean-in-place (CIP) sterilization, and provide leak-proof connections across high-purity industries. [1] ## ⚙️ Technical Specifications * Size Range: 1/2“ O.D. to 10” O.D. (Outside Diameter). * Design Standards: DIN, Tri-Clover (Tri-Clamp), IDF, SMS, RJT, BSP, and NPT. * Material Grades: Stainless Steel ASTM A403 WP304, 304L, 304H, 310, 316, 316L, 321, 321H, and 347. * Target Industries: Dairy, breweries, food & beverage, soft drinks, pharmaceuticals, cosmetics, distilleries, and sterile chemical processing. [2, 3] ------------------------------ ## 📋 Sanitary Component Classification## 1. Tri-Clover & Quick-Disconnect Union Components * Sanitary Ferrules: Flanged sleeves welded or expanded onto tube ends to create a hygienic mating surface. * Clamp & Gasket: A heavy-duty mechanical clamp joins two ferrules together, squeezing an elastomeric gasket between them to ensure a zero-leak seal. * Sanitary Adapters & Hose Ferrules: Transitions smooth-bore sanitary tubing safely over to threaded systems or flexible hoses. ## 2. Directional, Branching & Flow Manipulation Fittings * 90° & 45° Clamp/Welded/Threaded Elbows: Smoothly reroute fluid lines without dead corners where product could stagnate. * Sanitary Tees, Crosses, & Laterals: Form multi-directional junctions for distribution. * Sanitary True Y / Sanitary U Bends: Specialized splits and loops designed to maintain laminar flow profiles and cleanability. * Sanitary Reducers: Concentric or eccentric fittings that transition between mismatched tube diameters. ## 3. Sanitary Valves & Flow Control * Butterfly Valves (Welded, Clamped, Threaded, 3-Piece, Flanged): Space-saving quarter-turn valves used for high-frequency isolation. * Sanitary Ball Valves (2-Piece & 3-Piece Clamped): Provide a full, unrestricted bore for viscous or high-flow media. * Diaphragm & Zero Dead Leg Valves: Top-tier isolation components that prevent stagnant media zones, highly critical in pharmaceutical loops. * Plug (Cock) Valve & Non-Return Valve: Respectively handle manual throttling or prevent system backflow. ## 4. Inspection, System Cleaning & Closures * Sight Glass (Butt Weld & Clamp End): Inline transparent viewports to monitor product clarity, color, and flow conditions. * Spray-Cleaning Ball: Fixed or rotary fluid devices mounted inside tanks for automated CIP tank washing. * Conical Strainer: Traps particulate matter before it can damage downstream pumps or valves. * Sanitary End Caps & Thermometer Caps: Securely seal off open lines or integrate temperature sensor probes into the flow stream. ------------------------------ ## 🧴 Why Material Selection Matters (304L vs. 316L) * 304L Stainless Steel: Ideal for standard food, dairy, and beverage lines where corrosion risk is moderate. * 316L Stainless Steel: Crucial for high-acid environments (citrus, tomatoes), breweries, and pharmaceutical loops because it resists pitting from harsh CIP chemicals and chlorides. Are you sizing a system for a specific flow rate, or do you need to check the temperature rating for the gaskets (like EPDM, Silicone, or Viton)? Let me know how I can help you further.
