U-PVC FITTINGS WITH RUBBER RING SOCKET FOR CONDUCTS OF FLUIDS UNDER PRESSURE
Overview
This technical document is a comprehensive price list and specification guide for rigid PVC (U-PVC) fittings with rubber ring sockets, designed for pressurized fluid conduits. It covers product specifications, standards compliance, hygienic certifications, jointing procedures, performance data, detailed product dimensions, weights, pricing, and sales conditions. The document is multilingual (Italian, English, French, German) to serve a broad European market.
1. Specifications and Standards
The fittings comply with international standards EN ISO 1452, DIN 8063, ISO 2045, and ISO/DIS 6455, suitable for transporting pressurized fluids including potable water, wastewater, and food-grade liquids (oil, wine, milk).
- Minimum Required Strength (MRS): ≥ 25 MPa over 50 years (ISO 9080)
- Specific Weight: 1.35 - 1.46 g/cm³ (ISO 1183)
- Yield Load: ≥ 45 MPa (EN ISO 6259)
- Yield Elongation: ≥ 80% (EN ISO 6259)
- Young's Modulus: ~3000 MPa (EN ISO 6259)
- Longitudinal Tension: ≤ 5% (ISO 2505)
- Softening Temperature (Vicat): > 80°C (ISO 2507)
- Impact Strength: ≤ 10% (EN 744)
- Internal Pressure Resistance: 42 MPa for 1 hour at 20°C (ISO 1167)
- Joint Tightness Under Pressure: > 1 hour (ISO 1167)
- Shore Hardness D: 80-84 (ASTM D676)
- Thermal Conductivity: 0.13 Kcal/h·m·°C (DIN 52612)
2. Hygienic and Sanitary Certifications
Manufactured from Lareter rigid PVC pipes, the fittings meet hygienic standards for pressure conduits in multiple countries:
- Italy: Ministry of Health Decrees D.M. 21.03.1973 and D.M. 174/2004
- France: A.C.S. certification by I.P.L.
- United Kingdom: WRAS certification for public water supply
- Germany: Potability certification by Hygiene-Institut on behalf of DVGW
3. Jointing System - Rubber Ring Socket
The fittings utilize an elastomeric rubber ring socket joint that automatically compensates for thermal expansion and contraction, ensuring hydraulic tightness by applying uniform pressure around the pipe circumference.
Installation Steps:
- Clean gasket seat thoroughly
- Apply lubricant to facilitate gasket insertion
- Place gasket correctly in the socket
- Insert cleaned pipe end into the socket
4. Operating Performance and Pressure Ratings
Working pressure depends on temperature and pressure category (PN6, PN10, PN16) as per DIN 8061-62:
| Category | Temperature (°C) | Working Pressure (bar) |
|---|---|---|
| PN 6 | 20 | 6 |
| PN 10 | 20 | 10 |
| PN 16 | 20 | 16 |
| PN 6 | 40 | 4 |
| PN 10 | 40 | 6 |
| PN 16 | 40 | 8 |
| PN 10 | 60 | 2 |
| PN 16 | 60 | 3 |
5. Product Range and Pricing
The document details a wide range of fittings including sleeve sockets, bends (various angles), reduced sockets, male/female joints, tees, adapters, and reducers. Nominal diameters range from 50 mm to 400 mm, with weights and prices differentiated by pressure rating (PN10, PN16, and some PN8, PN5).
Example Pricing Data:
| Diameter (mm) | Length (mm) | Weight PN10 (g) | Weight PN16 (g) | Price PN10 (€) | Price PN16 (€) |
|---|---|---|---|---|---|
| 50 | 295 | 170 | 180 | 15.77 | 18.53 |
| 110 | 317 | 720 | 1080 | 25.44 | 40.61 |
| 400 | 642 | 27550 | 29000 | 527.39 | 591.97 |
6. Additional Product Categories
- Thermoformed bends (45° and 90° with radius R=1.5D)
- Guillotine shutters for sewage with pressure resistance and accessories
- HDPE hydrants with flanged connections including "BAUER" flange versions
- Polyethylene check valves
- Gaskets and accessories such as flat and pressure gaskets, adhesives (Tangit), cleaners, and lubricants
7. Installation and Usage Recommendations
- Use rubber ring socket fittings to ensure leak-proof joints under pressure
- Select fittings matching pipeline diameter and pressure rating
- Choose appropriate bend angles and joint types to optimize pipeline routing and minimize flow resistance
- Refer to weight and price tables for cost and logistics planning
- Use fittings with reduced pressure ratings (PN8, PN5) only where appropriate
8. Sales Conditions and Legal Information
- Delivery dates are indicative and subject to unforeseen events (e.g., epidemics, strikes, raw material shortages, force majeure)
- Claims must be made within 8 days of receipt; late claims or returns without prepaid postage are rejected
- Goods travel at purchaser's risk, even if sold free delivered
- Non-payment or partial payment may lead to suspension of deliveries and contract termination
- Claims or disputes do not justify payment delays; payments must be current for claims to be considered
- Late payments incur commercial interest; after 10 days overdue, sight drafts may be issued without notice
- Standard packaging is free; special packaging (cardboard, iron, wooden crates) incurs additional costs
- All disputes are subject exclusively to the jurisdiction of the Rovigo court, Italy, under Italian law
- Products can be tested free of charge by the Italian Institute for Plastics (IIP) upon request
