SylWrap Pipe Repair Bandages are water-activated and set rock hard in minutes, helping to strengthen and repair damaged and leaking pipework

SylWrap HD Pipe Repair Bandage

SylWrap HD Pipe Repair Bandage

SylWrap HD Pipe Repair Bandage is a water-activated composite wrap which strengthens and protects pipework, extending the lifespan of systems.

Applying SylWrap HD to a pipe increases pressure resistance, chemical resistance and hoop strength. A Pipe Repair Bandage will reinforce leak and damage repairs made using epoxy putties, pastes, coatings, or pipe repair tape by providing a rock-hard, impact resistant layer over initial sealant materials.

SylWrap HD is effective on pipes of all sizes made of steel, stainless steel, copper, malleable iron, GRP, ceramic, most plastics, clay, concrete, rubber, and lead. The fast-working resin infused in SylWrap HD means that the Bandage will begin to cure within minutes, allowing for rapid repairs to be made without the need for any formal training.

It is used in a wide range of industries. Desalination plants, wastewater treatment works, nuclear power plants and fire stations have all used SylWrap HD for pipeline reinforcement. The high chemical resistance of the Bandage enables it to repair hydrogen lines and sulphuric acid lines.

Water utilities companies in the United Kingdom keep SylWrap HD on their vans for reinforcing repairs to leaking pipes and burst water mains. SylWrap HD has WRAS Approval, meaning it is certified to British standards as safe to use on pipes carrying drinking water.

Sylmasta manufacture a specialist composite repair wrap for use in marine applications. SylWrap CR is infused with corrosion inhibitors to protect and strengthen metalwork against all forms of corrosion.

SylWrap Pipe Repair products are WRAS approved, one of the highest pipe repair accreditations that a product can achieve

How to strengthen and protect pipework with SylWrap HD

SylWrap HD is easy to use. Dipping the Bandage into water activates the resin. The Bandage is then wrapped around the pipework requiring strengthening or protection with further water used to smooth it down as the application continues.

SylWrap HD has a work time of 2-5 minutes. A functional cure is achieved in 30 minutes and a full cure with maximum properties in 24 hours.

To determine the size and quantity of SylWrap HD needed for a specific application, please go to the Repair Calculator Tab and enter your repair data.

Repair Calculator

SylWrap HD Pipe Repair Bandage Repair Calculator

The SylWrap Calculator determines the optimum SylWrap HD application for your pipe repair.

Enter the diameter of the pipe in millimetres, the length of the area to be repaired 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.
