A SylWrap Universal Pipe Repair Kit enables a user to fix a live leak on a pipe within 30 minutes without any formal training

SylWrap Universal Pipe Repair Kit –
For Live Leak Repairs

The SylWrap Universal Pipe Repair Kit enables any user to make a permanent, composite repair to pipework suffering from a live leak by following a simple two-stage process.

Pipelines do need to be drained before repair because the Universal Kit is effective even where pressure cannot be turned off. This avoids the time-consuming shutdown of equipment and provides a cost-effective alternative to replacement.

Repairs can be made in under 30 minutes to pipes of all sizes made from steel, stainless steel, copper, malleable iron, GRP, ceramic, most plastics, clay, concrete, rubber and lead.

The Kit seals leaks on difficult elbow joints, tee joints, welded joints and other challenging, non-straight pipe sections – offering a flexible alternative to heavy, bulky pipe repair clamps.

Repairs are pressure resistant up to 30 bar, temperature resistant to 200ºC and effective on pipes carrying hot water and chemicals. It has WRAS Approval, meaning it is certified to British standards as safe to use on pipes carrying drinking water.

Sylmasta also supply the SylWrap Pipe Repair Contractor Case for users carrying out regular pipe repairs. The Case is easy to store on the van or on site and contains enough Universal Kit products to make up to six live leak repairs.

Water companies in the United Kingdom, Canada, Mexico and Malaysia use SylWrap Contractor Cases for the speed and ease with which they repair live leaks on the public supply network.

Other industries using SylWrap Kits include quarries, mines, wastewater treatment, district heating, agriculture, petrochemical plants, oil rigs, nuclear power stations, freight ships, super yachts and within public buildings including hospitals, hotels and airports.

How to make a live leak pipe repair with a SylWrap Universal Pipe Repair Kit

The SylWrap Universal Pipe Repair Kit contains two sealing materials – Superfast Steel Epoxy Putty and Wrap & Seal Pipe Burst Tape – and a SylWrap HD Pipe Repair Bandage.

Superfast Steel for offline pipe repair

Superfast Steel is a fast-working epoxy putty in a pre-measured stick for sealing holes and cracks in pipes where water pressure can be turned off. It also removes step from joints and improves the condition of pitted pipe surfaces prior to the application of Wrap & Seal.

Users knead the epoxy putty by hand until it turns a uniform grey colour. It is then pushed into cracks whilst soft. Within 5-10 minutes, Superfast Steel hardens to form a solid, watertight material filling the hole.

When pipe reprofiling, Superfast Steel is pressed firmly onto the area requiring improvement. It creates a flat, smoother surface which is easy to apply Wrap & Seal onto.

Wrap & Seal Pipe Burst Tape for live leak pipe repair

Wrap & Seal Pipe Burst Tape is a self-amalgamating waterproof pipe repair tape capable of sealing live leaks. An online repair starts by anchoring Wrap & Seal next to the leak. It is then wrapped directly over the leak area.

The tape stretches by 300 percent its length. It fuses into a solid rubber band as it is wrapped towards and then directly over the leak. The rubber band exerts pressure over the leak to contain pipe content.

Additional tapes applied on top of each other will amalgamate in the same way. Multiple Wrap & Seals can build a live leak repair resistant up to 30 bar.

SylWrap Universal Pipe Repair Kits covering pipework in excess of 150mm include a SylPad Pressure Resistance Multiplier.

SylPad used in conjunction with Wrap & Seal better concentrates the elastic force of the tape directly over holes up to 20mm on larger diameter pipes.

Using SylPad multiplies pressure resistance by up to three times. This enables a faster repair by reducing the number of tapes needed.

If you are undertaking a high-pressure application, please go to the Repair Calculator tab and enter your repair information. The calculator will then determine the number of tapes required for your application.

Each Universal Kit comes with one Wrap & Seal. Additional tapes are purchased separately where required.

Reinforcement with SylWrap HD Pipe Repair Bandage

The second and final stage of the repair is reinforcement with SylWrap HD Pipe Repair Bandage after application of the sealing material.

Wetting the bandage activates the resin. The bandage is then wrapped around the pipe and smoothed with water. It sets within 5 minutes to provide a rock-hard, impact-resistant layer of protection for a permanent repair.

Repair Calculator

Wrap & Seal Repair Calculator

The below Wrap & Seal Calculator recommends the number of Wrap & Seal Pipe Burst Tapes required to seal a live leak based on pipe diameter and pressure.

Enter the diameter of the pipe in millimetres, water pressure and the size of the hole requiring sealing in millimetres. The safety factor is a multiple to include a margin of safety. For example, if pipe pressure is 5 bar and you want a safety factor of two, the calculator will formulate a repair capable of withstanding 10 bar.

Once data is entered, selecting the size of Wrap & Seal determines how many of that specific tape are required for a repair. Repairs to pipes in excess of 150mm diameter with Wrap & Seal PB-50x4m or PB-50x11m should be made in conjunction with SylPad.

Calculations serve as a guide to potential maximum pressure resistance only. Actual pressure resistance depends upon pipe material, condition, hole size, leak type and tension maintained during wrapping. If you are unsure, more than one Wrap & Seal can be used to stop the leak.
