SylWrap HD Pipe Repair Bandage

SylWrap HD Pipe Repair Bandage is a composite fibreglass wrap with a water-activated resin which sets rock hard in minutes to provide high-strength reinforcement of leaking or damaged pipes.

A SylWrap Repair Bandage strengthens pipes and structures made from steel, copper, malleable iron, GRP, ceramic, clay, and most plastics. The Pipe Repair Bandage increases pressure resistance, chemical resistance and hoop strength, and extends the lifespan of metalwork and other materials.

SylWrap HD is also used to reinforce repairs made with other Sylmasta products. Applying SylWrap HD over a leak sealing material such as Superfast Epoxy Putty or Wrap & Seal Pipe Burst Tape provides a rock hard, impact resistant layer over the initial sealant, offering a permanent solution. SylWrap HD has WRAS approval and so can be used with drinking water.

SylWrap Bandages have been used to make repairs in desalination plants, wastewater treatment works, nuclear power plants, fire stations and to water supply lines. Their high chemical resistance have seen them fix hydrogen lines and sulphuric acid lines while many water utilities companies keep SylWrap HD on their vans for reinforcing repairs to leaking pipes and burst water mains.

The below calculator can be used to determine the optimum SylWrap HD application for your pipe repair.

Enter the diameter of the pipe to be repaired, the length of the damage area and the pressure resistance required.

The safety factor is a multiple to include a margin of safety. For example, if pipe pressure is 10 and you want a safety factor of two, then the calculator will formulate a repair capable of withstanding 20bar.

Once you have entered your data, the calculator will show the size of SylWrap HD, the quantity of bandages required, and the number of layers which should be wrapped.
