VIP-WECO TRENCHLESS REPAIR SEAL

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.

Our VIP-WECO are WRAS approved, 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
