IFAN Floor Heating PEXa Pipe – Flexible Cross-Linked Polyethylene Tubing for Underfloor Heating

Product Overview

PEXa Pipe is engineered for modern underfloor heating installations, residential hot and cold water distribution, and other suitable plumbing applications. Manufactured from new, high-quality raw materials, this tubing uses the peroxide cross-linking process to create a highly cross-linked polyethylene structure. The resulting material combines flexibility, thermal stability, pressure resistance, and long-term performance under appropriate operating conditions.

Key Features of IFAN PEXa Pipe

1. Peroxide Cross-Linked Material

IFAN PEXa pipe is produced using peroxide cross-linking technology, which forms a three-dimensional molecular network within the polyethylene material. This structure improves resistance to heat, mechanical stress, and deformation compared with ordinary non-cross-linked polyethylene pipe. The high degree of cross-linking supports dependable performance in properly designed heating systems.

2. Multiple Sizes and Pressure Ratings

Available in nominal sizes from 16–32 mm, with wall thicknesses ranging from 1.8–4.4 mm, IFAN PEXa tubing accommodates different project specifications. Pressure ratings include PN12.5, PN16, and PN20, subject to the applicable product dimensions and technical specifications. Buyers can select suitable configurations according to system design, operating temperature, pressure, and local standards.

3. Excellent Flexibility for Floor Heating

Flexible PEXa tubing can follow curved installation routes with fewer elbows and intermediate joints. This characteristic is particularly useful when laying underfloor heating circuits across rooms and around designated obstacles. Reducing unnecessary connections can simplify installation and help minimize potential leakage points.

4. High-Temperature and Low-Temperature Performance

IFAN PEXa pipe is designed for heating applications requiring thermal stability. Under suitable system conditions, it can operate continuously at temperatures up to 95°C, with short-term exposure to temperatures up to 110°C where permitted by the product specification. Its material properties also support low-temperature performance down to approximately -70°C under appropriate conditions. Actual service life depends on temperature, pressure, installation quality, and operating cycles.

5. Pressure Resistance and Thermal Memory

The cross-linked structure helps the pipe withstand pressure and repeated temperature changes when used within its rated limits. PEXa also features thermal memory: when a compatible deformation occurs, controlled heating may help the pipe recover its original shape. Heating and repair procedures must follow the manufacturer's instructions to avoid damaging the tubing.

6. Compatible Accessories and Protective Sleeves

For added installation flexibility, IFAN PEXa pipe can be combined with suitable insulation sleeves or corrugated protective conduits. Depending on the connection design and applicable standards, compatible fittings may include PPSU push-fit fittings, press fittings, sliding-sleeve fittings, and compression fittings. Correct sizing and fitting compatibility are essential for a secure connection.

Applications and Benefits

PEXa pipe is especially suitable for hydronic underfloor heating, where warm water circulates through tubing installed beneath the floor surface. Its flexibility helps installers create smooth heating loops and reduce connection points within the floor structure.

When integrated with an appropriate manifold, thermostat, and control system, support independent room or zone temperature adjustment. This allows users to regulate heating according to individual room requirements and improve indoor comfort. Proper hydraulic balancing and system design are important for consistent heat distribution.

PEXa tubing also offers resistance to corrosion and does not develop internal rust like conventional steel pipe. Combined with appropriate insulation, correct installation, and operation within the specified temperature and pressure limits, it can provide dependable service for residential and commercial heating projects.
