Polyethylene Pipework Systems
Polyethylene, often referred to as PE, is a widely used thermoplastic pipework
material for pressure, infrastructure, utility, and industrial applications. It is commonly selected where flexibility, corrosion resistance, low weight, abrasion resistance, low maintenance, and reliable long-term performance are important.
PE pipework is used across water, gas, wastewater, industrial, buried pipeline,
surface pipeline, and temporary pipework applications. It is particularly useful where secure jointing, ease of handling, and resistance to ground movement or challenging installation conditions are required.
At IPS, we supply polyethylene pipework systems including AGRU Kunststofftechnik GmbH AGRULINE PE 100-RC pressure pipe systems, fittings, flanges, backing rings, gaskets, valves, electrofusion fittings, socket fusion fittings, fusion spigot fittings, and supporting accessories.
PE systems should always be specified using the correct resistance class, pressure rating, SDR, temperature conditions, jointing method, installation environment, and chemical compatibility for the application. Final suitability should always be checked against the relevant technical data before specification or installation.

Key features of polyethylene pressure pipework systems
Fusion-welded polyethylene pressure piping is used across drinking water, gas and
wastewater networks. Systems such as AGRULINE are built from PE 100-RC pipes,
fittings and accessories, and are designed for a long service life and leak-tight joints
when correctly designed, installed and operated in line with the applicable standards.
The high stress crack resistance of PE 100-RC supports that long service life, and
the homogeneous, force-locked joints provide long-term leak-tightness.
Flexible and impact resistant
Polyethylene is flexible and has strong impact resistance, making it suitable for buried pipelines, surface pipelines, temporary pipework, and installations where ground conditions may be uneven or unstable. Its flexibility can support easier installation and help accommodate movement. The system must still be designed correctly for pressure, temperature, jointing method, support, ground conditions, and external loads.
Corrosion and chemical resistance
PE does not corrode like metallic pipework and offers good resistance to many substances encountered in industrial, utility, and infrastructure applications. Chemical suitability depends on the exact medium, concentration, temperature, pressure, and operating conditions. PE is not suitable for strong oxidising acids, so compatibility should always be checked against the relevant chemical-resistance data before specification.
Welded joint integrity
PE pipework is commonly joined using heat-fusion methods such as butt fusion, socket fusion, and electrofusion welding. AGRULINE is jointed by heated tool butt welding or electrofusion welding, producing homogeneous, force-locked connections. These methods can create secure, reliable joints when the correct equipment, preparation, welding procedure, and operator training are used. Mechanical fittings, flanges, and transition connections may also be used in selected installations, depending on the system design and service conditions.
Lightweight and easy to handle
Polyethylene has a relatively low weight compared with many metallic pipework materials, making it easier to transport, handle, and install on site. Depending on size and pressure class, some PE pipe may also be supplied in coils to support efficient installation. Above-ground PE pipework requires suitable support. Support spacing, expansion allowance, temperature, pipe size, pressure class, and layout should all be considered before installation.
Smooth internal bore
PE pipework has a smooth internal surface, helping to support efficient flow and reduce friction losses. Combined with homogeneous jointing, this supports excellent flow characteristics and helps maintain system performance when the pipework is correctly sized, installed, and operated within its stated limits.
Suitable for demanding installation methods
PE systems are often selected for buried and infrastructure applications because of their flexibility, welded jointing options, and suitability for long pipeline runs. AGRULINE is suitable for both new installations and trenchless pipe rehabilitation, including sand-bed-free installation and alternative, no-dig installation methods. The specific product range, ground conditions, approvals, pressure class, and installation method should always be reviewed before selection.
