The lightweight new tools, initially available in North America before a global launch later in 2013, are self-centring, self-adjusting and reduce installation guesswork. Their low weight means typical sizes can be handled more quickly and efficiently.

Their main application is for branch-line pipework, where they can isolate the line completely; create a vapour barrier for hot work or localise a line for flange weld testing.

Aluminium variants have been available from Hydratight in Europe for some time, where they have proved very successful: “The technology is a perfect complement to Hydratight’s many current products and services,” said Western Region leader Steve Earney.

“As a company we offer many solutions to ensure bolted pipework integrity. The in-line weld test tools are a natural extension of our general pipework integrity products. It makes it possible, in many cases, to have one technician do work that previously had to be done by two people, and to the same level of accuracy.”
