The standard rigid coil system PermaWrap® comes in 5 different widths, suitable for pipe diameters from 4” up to 60”. The most used width is 12” wide and has 8-layers. It can be used for most of the defects in transmission pipelines. In case a defect is smaller, a 6” wide or a 9” wide PermaWrap® can be installed. A cost effective solution. If a defect is bigger, PermaWrap® 15” or 18” will suit your needs, without installing two 12” wide sleeves. The unique feature of PermaWrap® is the fact the sleeve is magnetically detectable. It will become a standard solution for a permanent repair with external wall loss up to 80%.

Girth welds and rigid coil systems are not a good combination. In current practice several sleeves have to be installed for one repair to make it a compliant repair. This is not only costly be also time consuming. WeldWrap® is the solution in these situations. With its superior laminate construction WeldWrap® will repair the girth weld with one single rigid coil system. All features and compliances of PermaWrap® are also applicable to WeldWrap®.
