Product Description

 

U PIPE FITTING PRODUCT MANUAL

1. Product Overview

• Definition: A U-shaped pipe fitting designed to redirect fluid flow, secure pipelines, or enable specific functions (e.g., siphon effects).
• Types:
  • U-Bolts: For pipeline/equipment fixation (materials: stainless steel, carbon steel).
  • U-Clips: Reinforced fasteners for high-pressure/vibration environments.
  • U-Bends: Weldable or threaded fittings for directional changes.
• Materials: Stainless steel (304/316L), carbon steel, copper, PVC, UPVC, PPR, etc., tailored for diverse media and environments.

2. Technical Specifications

 

Parameter	Details
Size Range	Diameter: M6-M64 (1/4"-2-1/2"), U-width: 22mm-328mm (customizable)
Pressure Rating	Stainless steel: PN16-PN40 (high-pressure); Plastic: PN10 (low-pressure)
Temperature Range	Metal: -80°C to 450°C (material-dependent); PVC-U: -10°C to 60°C
Standards	GB/T9948, GB/T13296, ASME B16.9, DIN 2616

3. Key Advantages

• Corrosion Resistance:
  • Stainless steel: Ideal for chemicals/marine environments.
  • PVC-U: Excellent acid/alkali resistance for drainage systems.
• Easy Installation:
  • Lightweight design (e.g., PVC-U: 1/5th the density of iron).
  • Modular design for rapid assembly.
• Fluid Efficiency:
  • Smooth interior reduces resistance, boosting flow by 15-30%.
  • Siphon design accelerates drainage.
• Customization:
  • Non-standard sizes, specialty alloys (e.g., Hastelloy), and specialized shapes (e.g., Π-shaped).

4. Applications

7. Selection Guide

1. Media & Temperature:
   • Corrosive media: 316L stainless steel or PVC-U.
   • High-temperature: Carbon steel or alloy steel (e.g., A234 WP11).
2. Pressure:
   • High-pressure: Seamless steel + welding.
   • Low-pressure: PVC-U + adhesive bonding.
3. Space Constraints:
   • Compact areas: Small U-bends (DN15-DN50).
   • Large diameters: Welded U-pipes (≥DN600).
