VIP-Polymers have for a number of years developed and manufactured a range of sealing gaskets for pipe fittings and repair clamps used on a variety of applications:

End load restraint systems Repair couplings Repair clamps (using “waffle pattern” repair mats) Stepped couplings Flange adaptors Dismantling joints Shoulder couplings Gripper couplings

With an advanced rubber to metal bonding facility available in-house, we can also offer reinforced repair mats incorporating components made from stainless steel, lead, aluminium, copper and iron. Large compression and injection moulding presses enable us to offer components up to 2.4 metres wide whilst our extrusion facility enables us to produce profiles of up to 300mm width.

Approvals

Many of the compounds we use to manufacture repair clamp gaskets hold multi-region potable water approvals. This means our customers enjoy the benefits of reduced inventory as stocks of gaskets for different global regions are no longer necessary.

VIP-Weco – Fully installed in as little as 40 minutes!

Since the 1960s VIP-Weco internal pipe seals have been used worldwide for trenchless rehabilitation of pipes and sewers for industrial water, drinking water, waste water, fuel and gas.

VIP-Weco use WRAS approved material, comply fully with BS6920 and have a typical life expectancy of 50+ years.

During the installation process, rubber sleeves made of EPDM or NBR compounds are applied over the damaged area of the inner wall of the pipe. The rubber sleeve is then held in place by stainless steel retaining bands allowing up to 20 bar of internal or up to 2.0 bar of external pressure.

Following installation of clamping bands in the corresponding grooves of the sleeves, a safe, durable and low-cost mechanical sealing solution is achieved. Typical installation time of circa 40 minutes per seal.

For special applications, we develop customised sealing solutions on request.

In addition to the VIP-Weco seals, our services include:

• Pipeline repair & rehabilitation consultancy services
• Installation and testing of VIP-Weco seals where required
• Training and accreditation for third party installation of the VIP-Weco sealing system
