Wrap & Seal Pipe Burst Tape

Wrap & Seal Pipe Burst Tape is a self-amalgamating pipe repair tape which seals leaking pipes of all types and diameters even when water pressure cannot be turned off.

It is twice the thickness of other waterproof tapes and stretches by 300% of its length, allowing for more pressure to be applied per wrap.

As Wrap & Seal is wrapped around a pipe, it fuses together to form a solid rubber band exerting maximum pressure over the hole or crack to contain pipe content.

Multiple tapes applied on top of each other will amalgamate in the same way. It is possible to build a repair capable of holding up to 30 bar pressure.

Because Wrap & Seal is effective on live leaks, it avoids costly and disruptive shutdowns of systems. Wrap & Seal is temperature resistant to 200ºC, and is used on pipes carrying hot water and chemicals.

No prior training is required to use Wrap & Seal – simply follow the instructions supplied and apply the tape. It has WRAS Approval, meaning it is certified to British standards as safe to use on pipes carrying drinking water.

Wrap & Seal is used in applications ranging from small domestic plumbing problems to large scale industrial pipe repairs. It is effective on steel, stainless steel, copper, malleable iron, GRP, ceramic, most plastics, clay, concrete, rubber, and lead.

How to fix a leaking pipe using Wrap & Seal Pipe Burst Tape

Fixing a leaking pipe with Wrap & Seal Pipe Burst Tape is straightforward. Depending on the diameter of the pipe and the number of tapes used, repairs can be made in less than 15 minutes.

The repair begins by anchoring Wrap & Seal next to the leak area. Using the centre line of the tape as a guide, you stretch it to its maximum and wrap tightly over the hole in the pipe until the tape runs out.

As you apply Wrap & Seal, it fuses into a solid rubber band, sealing the leak. The unique tapered profile of Wrap & Seal stops water from tracking underneath the tape, maximising surface contact with the pipe.

Each layer of tape increases the pressure resistance of the repair. If the leak is not sealed after application of one Wrap & Seal, further tapes should be added on top to increase pressure resistance.

To determine how many Wrap & Seal are required to make a repair up to a certain pressure on a specific pipe diameter, please use the Repair Calculator.

When repairing holes up to 20mm on pipes in excess of 150mm, a SylPad Pressure Resistance Multiplier can be used in conjunction with Wrap & Seal.

SylPad better concentrates the elastic force of the tape directly over the leak on larger diameter pipework, multiplying pressure resistance by up to three times.

To reinforce pipe repairs made with Wrap & Seal, Sylmasta recommend overwrapping the Tape with a SylWrap Pipe Repair Bandage. The Bandage offers a rock hard, impact resistant layer of protection.

SylWrap can either be purchased separately, or alongside Wrap & Seal as part of the Universal Pipe Repair Kit or the Pipe Repair Contractor Case which contains enough tapes and bandages to make up to six repairs.

Repair Calculator

Wrap & Seal Repair Calculator

The below Wrap & Seal Calculator can be used to determine the recommended 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.

After entering your data, selecting the size of Wrap & Seal will determine how many of that specific tape are required for your repair. Repairs being made 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.

Emergency live leak repair using Wrap & Seal

Demonstration video filmed at Sylmasta HQ to show the live leak repair capabilities of Wrap & Seal.

A pinhole was drilled into a pressurised steel pipe. One 50mmx4m Wrap & Seal was then used to seal the leak in under 10 minutes.

After the repair was completed, pressure was increased to 5 bar. The solid rubber band formed by Wrap & Seal during the repair was easily able to withstand the sudden increase.

The tape was then overwrapped with SylWrap HD Pipe Repair Bandage, which set rock hard to provide an impact-resistant layer of protection.

Leaking step joint repair at Bahrain International Airport

The maintenance team at Bahrain International Airport make a live leak repair to a 100mm UPVC pipe leaking through a step joint.

Wrap & Seal was used to build a repair up and over the step, preventing water seeping out. SylWrap HD then reinforced the repair.

The application took under 30 minutes whilst the system the pipe was connected to remained operational, meaning there was no disruption to the airport.

Using SylPad to increase Wrap & Seal pressure resistance

Demonstration video showing SylPad increasing the pressure resistance of Wrap & Seal during a live leak repair to a 7.2mm hole in a 450mm steel pipe operating at 3 bar.

Such a repair without SylPad would require four 50mm x 4m Tapes. Using SylPad, the leak was sealed with one Tape.

With two further tapes added, the completed repair was capable of holding 9 bar pressure.
