Ductile Iron Gibault Joints for PVC Pipes

Discover the professional solution for jointing and repairing pipes with our range of ductile iron Gibault joints. Designed for superior performance in water networks, these joints guarantee quick installation, a hermetic seal and exceptional durability. They are the preferred choice of experts in agricultural irrigation, water supply networks and civil construction who demand maximum reliability.

What are Gibault Joints and what are they for?

A Gibault joint is a mechanical coupling that joins the plain ends of two pipes without the need for welding, threading or flanges. Its function is to create a robust, watertight connection by means of a compression system. As the bolts are tightened, the end rings press the rubber gaskets against the pipe and the central body, ensuring a hermetic, long-lasting seal.

These elements are fundamental in the water sector, both for installing new networks and, crucially, for pipe repairs. They allow damaged sections to be replaced quickly and effectively, absorbing slight misalignment and vibration, which makes them an economical and reliable solution for infrastructure maintenance.

Key Advantages of Our Gibault Joints

Our selection stands out for a quality of materials and a design that guarantee superior performance and complete peace of mind in every installation.

• Maximum Strength and Durability Our joints are manufactured in Ductile Iron (GGG-50), a material with far greater impact resistance than conventional grey cast iron (GG-25). This prevents cracking or breakage of the rings when the tightening torque is applied, a common problem with lower-grade joints. The epoxy coating protects against corrosion, ensuring a long service life.

• Quick, Safe Installation The mechanical design of the Gibault joint simplifies assembly on site. By eliminating the need for specialised machinery or welding, installation times and labour costs are reduced. A single operative with basic tools can make a secure connection in minutes.

• Guaranteed Hermetic Seal We use high-quality rubber gaskets (EPDM) that conform perfectly to the pipe surface. This system guarantees complete watertightness, capable of withstanding working pressures of up to 16 bar (PN-16), preventing any leak.

• Versatility of Application Although optimised for PVC pipes, their flexibility allows their use on a variety of materials, including polyethylene (PE), resolving multiple connection and repair scenarios.

Main Applications

• Agricultural Irrigation Systems: Ideal for quick repair of bursts in PVC pipes and for connecting new irrigation sectors or hydrants.

• Water Supply Networks: Used in municipal infrastructure to join pipes in distribution networks, guaranteeing security of supply.

• Treatment Plants and Drainage: Suitable for connecting pipes in treatment plants and sewerage systems thanks to their strength and flexibility.

• Industrial Installations and Construction: They provide reliable, demountable connections in piping systems for industrial processes or temporary pipelines on sites.

Quick Installation Guide

Correct installation is the key to performance. Follow these steps for a secure connection:

1. Preparation: Make sure the pipe ends are clean, free of burrs and cut square.

2. Assembling the Components: Dismantle the joint. Slide onto each pipe end first the end ring and then the rubber gasket.

3. Positioning the Body: Place the central sleeve between the two pipe ends.

4. Final Adjustment: Bring the gaskets and end rings up until they contact the central body.

5. Uniform Tightening (Critical Step): Insert the bolts and tighten the nuts gradually and in a cross pattern (like the bolts on a wheel). This distributes the pressure evenly over the gasket, guaranteeing a hermetic seal.

Frequently Asked Questions (FAQ)

What working pressure do these joints withstand? Our ductile iron joints are designed for a nominal pressure (PN) of up to 16 bar (232 PSI). We recommend checking the technical data sheet for each model.

What is the difference between ductile iron and grey cast iron? Ductile iron (GGG-50) has greater tensile and impact strength, which prevents brittle fractures during tightening. Grey cast iron (GG-25) is more brittle and susceptible to cracking under stress, making it a less safe option.

Can I join a PVC pipe to a steel pipe? Yes. To join pipes of different materials, we recommend using a Universal-type Gibault joint, designed to absorb slight variations in diameter and guarantee the seal.

Do I need special tools? No. Only standard open-ended or socket spanners are required to tighten the bolts, which makes them a practical, economical solution.
