Polyethylene pipe

Product catalog summary

Introduction
Polyethylene pipes are highlighted as an effective alternative to traditional materials like cast iron, steel, and concrete due to their technical and economic benefits. Their widespread use is attributed to unique properties that enhance performance and cost-efficiency.

General Features

Abrasion Resistance: Superior to steel and concrete, suitable for transporting solid particles and dredging.
Flexibility: High flexibility allows absorption of vibrations and stress, ideal for unstable areas.
Lightness: Low specific weight facilitates easy transportation and installation, reducing costs.
Corrosion Resistance: Chemically inert, resistant to cracking, corrosion, and microbial growth.
Chemical Resistance: Withstands a wide range of chemicals.
Thermal Stability: Stable under normal temperature variations.
Low Temperature Performance: Effective at temperatures as low as -60°C.
UV Resistance: Carbon black addition prevents UV degradation, suitable for outdoor storage.
Non-Toxicity: Complies with health standards for potable water transport.

Technical Features
Detailed specifications for PE 80 and PE 100 high-density polyethylene include:

Density: 954 kg/m3 for PE 80, 958 kg/m3 for PE 100.
Yield Strength: 22 MPa for PE 80, 23 MPa for PE 100.
Thermal Conductivity: 0.45 W/m.k for PE 80, 0.38 W/m.k for PE 100.
Minimum Required Strength (MRS): 8 MPa for PE 80, >10 MPa for PE 100.

Applications
Used in irrigation, water supply, gas lines, fire hydrants, sewers, and industrial fluid transport. Standards include UNI 7613, UNI EN 12201, and EN 1622.

Product Specifications
Includes dimensions, thickness, and standards for PE 80 and PE 100 pipes with various pressure ratings and size ranges.

Specifications
Manufactured according to UNI 7990:2004 and UNI ISO 4437 Type 316 standards, available in pressure ratings PN 4, PN 6, PN 10, and sizes from 16 mm to 630 mm. High-density polyethylene (PE 80) is used for gaseous fuel, and low-density polyethylene (PE 40) for other applications.

Procedures
Produced in compliance with the Italian Ministerial Decree of 24/11/1984, suitable for buried gas distribution systems.

Formats
Available in 6 m and 12 m lengths, and coils of 50 m, 100 m, 200 m, and 500 m.

Standards and Approvals
IIP-UNI approved for diameters from 16 mm to 110 mm for PN 4, PN 6, and PN 10, and from 20 mm to 630 mm for S 12.5, S 8, and S 5.

Key Data
SDR values provided for different pipe sizes and applications. Safety factor for high-density polyethylene pipes is 3.25.
