Repair without interrupting the water supply using the repair sleeve

The repair sleeve is a piece of equipment that can be used to repair damaged pipes or prevent water leaks in fragile areas of the network.

Repair without interrupting the water supply using the repair sleeve

When it comes to working on water networks, reliable and effective solutions are needed to minimise service interruptions while guaranteeing a continuous supply of drinking water. The repair sleeve is a key innovation in this field, offering a fast and suitable method of repairing damaged pipes without interrupting the supply.

The repair sleeve is a solution specially designed to seal leaking or ruptured pipes, while maintaining the water supply to users. This system consists of a metal cylinder (often made of steel, stainless steel or cast iron) that wraps around the damaged pipe in order to repair it temporarily or permanently, depending on what type of work is being carried out.

 

One of the main advantages of the repair sleeve is that it enables repairs to be made without having to cut off the network, thus avoiding the inconvenience associated with interrupting the water supply. This solution is ideal for operations in urban areas, where interruptions can affect a large number of homes or businesses. With this system, operators can respond quickly and effectively, while keeping service interruptions to a minimum.

Advantages of the repair sleeve

The repair sleeve has many advantages, making it a preferred solution for water network operators:

  • Repair without interrupting the service: By design, the sleeve allows the flow of water to be maintained while the repair work is being carried out, which is essential to guarantee continuity of service, even in the event of a fault.
  • Adaptable: This coupling system comes in a variety of configurations, sizes and materials and can be adapted to a wide range of pipes, both old and new. It can be applied to all pipe materials and is suitable for different types of use (isolated hole, fitting, crack, clean break).
  • Easy to fit: The sleeve is designed to be quick to fit, using standard tools, thereby reducing work time and making emergency repairs easier.
  • Versatile: It is equally suitable for temporary repairs and long-term operations, as required by the specific needs of the network.
  • Preventive: If part of the network is considered to be fragile, a repair sleeve can be fitted before a potential leak occurs.

Repair products, commonly referred to as "repair sleeves", come in a number of different shapes and sizes and are available in the EIE catalogue:

  • Sleeves (for ruptures and "leaky" butt joints)
  • Saddles (to repair a leak in a pipe with a clearly defined hole)
  • Flanges (to prevent or repair a leak on a fitting)
  • Made-to-measure repair parts

 

Technical innovation to serve networks

Some repair sleeves, such as those developed by the Claire Group, are designed to cater for specific situations. For example, the sleeve patented by EIE, a subsidiary of the Claire Group, can compensate for angular or in-line offsets, which are a common occurrence when pipes are exposed to displacement or major cracks.

This articulated sleeve can be used to repair misaligned pipes, by adapting to ground movements or impacts sustained by the pipes. It can compensate for angular offsets of up to 10° on pipes with diameters of less than 300 mm, and in-line offsets of up to 15 mm for small diameters.

A ready-to-use solution for operators

The repair sleeves available from the Claire Group are part of a complete range of solutions for the maintenance of water networks. These solutions cover the repair of pipes using a broad range of equipment for all uses (sleeves, saddles, flanges and made-to-measure parts), which is essential to stop leaks and protect Water resources.

With its robust design and straightforward installation, the repair sleeve guarantees effective operations that safeguard water networks over the long term.

This is a particularly useful and responsive system once a leak has been pinpointed, to swiftly rectify the problem of water loss. To safeguard against broken pipes, it is advisable to monitor the drinking water network at all times. With water network monitoring systems, risks can be anticipated before they become critical.
