Product catalog summary

Introduction to PE 100 Fittings
PE 100 fittings are utilized in applications such as water and gas distribution, irrigation systems, and industrial facilities. They are valued for their impact resistance, corrosion and chemical resistance, flexibility, and lightweight nature, which reduces transportation and handling costs.

Electrofusion and Butt Welding
Electrofusion: This technique uses resistance wires within the fitting to create non-detachable welded joints. It is easy to install, compatible with various pipe types, and suitable for all fitting sizes with the same machine, especially recommended for sizes up to 90 mm.
Butt Welding: This method involves aligning and pressing the welding faces against a heating element until the welding temperature is reached. It is ideal for larger diameters and requires careful execution for smaller sizes due to thinner walls.

Material Properties of PE 100
PE 100, a third-generation polyethylene, offers superior density and mechanical properties compared to previous versions. It complies with EN 12201 and EN 1555 standards for drinking water and gas supply systems, with a density of 930 kg/m³, a melt-flow index of 0.3-0.5 g/10 min, and a longitudinal expansion coefficient of 0.13 mm/m.k.

Geometric Properties and Nominal Pressures
The Standard Dimension Ratio (SDR) defines the relationship between outer diameter, wall thickness, and nominal pressure. For PE 100, SDR 11 corresponds to PN 16, and SDR 17 corresponds to PN 10, crucial due to varying international safety factors.

Specifications and Standards
The document highlights the importance of SDR in correlating wall thickness with outer diameter, considering international safety factors of 1.6 and 1.25. It specifies geometric properties and nominal pressures according to EN 1555 and EN 12201, with examples like PE 100 SDR 11 PN 16 and PE 100 SDR 17 PN 10.

Applications
Applications include wastewater transport, water treatment, solid transport, water and gas distribution networks, irrigation systems, and swimming pools.

Welding Techniques
Electrofusion is a simple and quick technique for creating non-detachable welded joints using electrofusion couplers and equipment. It involves resistance wires within the electrofusion socket, with recommendations for barcode systems to automate welding parameters.

Material and Safety
PE material complies with EN 12201 and EN 1555 standards, with a welding voltage below 40V. The welding zone must be protected from adverse weather, and fittings come with a welding control indicator. The process should be conducted by trained personnel, following DVS 2207 part 1 specifications.

Preparation and Assembly
Preparation involves cutting the pipe perpendicularly and cleaning surfaces with alcohol. Welding faces must be treated immediately before welding, with pipes secured to prevent movement. Maximum pipe ovalness is limited to 1.5% of the outer diameter.

Welding Process
Welding parameters can be input automatically via a barcode reader or manually. The sequence is fully automated, with the machine controlling and recording all data for documentation. Post-welding, indicators should be checked to ensure completion, though they do not guarantee weld quality.

Specifications and Equipment Requirements
Specifications for butt welding of thermoplastics are based on DVS 2207 part 1 standard, requiring a special welding machine for secure clamping and proper alignment. Heating surfaces must be flat and parallel, with a temperature variation not exceeding 10ºC.

General Conditions
The welding area should be protected from adverse weather to prevent temperature variations in the parts to be joined.

Preparation Before Welding
Before welding, the heating element's temperature should be checked with a thermometer. It must be cleaned with dry, lint-free paper before each weld. Components should be planed and aligned according to ISO 12176-1 standards.

Welding Procedure
Different pressures are applied during equalization, jointing, and pre-heating phases. Parts are pressed against the heating element until a bead forms, then joined with adequate pressure, maintained during cooling. A double bead should form around the circumference, and joints must cool completely before pressure testing, with a minimum wait time of one hour after the last weld.

Data and Parameters
Tables include specific parameters for different pipe diameters, with code references, SDR, PN, and dimensions for 90º and 45º elbows, indicating necessary specifications for various joint configurations.
