With the recent rash of natural gas pipeline explosions, many caused by pipeline corrosion, there is a watchful eye on how owners are handling the maintenance and repair of their pipelines. To some companies the problems may seem bigger than life as there are millions of miles of aging natural gas pipelines in the United States alone. Pipeline owners are being forced to take a proactive stance to this problem by identifying areas of their lines which are in need of repair, remediation or restoration.
A product called A+ Wrap manufactured by Pipe Wrap LLC has been identified as an effective method to extend the life of high pressure natural gas pipelines. The product has been tested, approved and meets D.O.T. requirements as a permanent pipeline repair. The repair solution is a strong composite sleeving system which permanently repairs gouges, cracks, dents as well as external defects associated with pipe that has been compromised as much as 80 %. The A+ Wrap system is composed of a two-part putty which is activated when mixed together, along with a composite wrap; it is pliable, water activated and restores pipe to its full-strength condition.
A+ Wrap repairs defects near welded areas (up to 50% wall loss) or along any shapes or configurations including reducers, bends, tees, manifolds or elbows. However, it does not repair cracks, gouges or dents in longitudinal or girth welds.
A+ Wrap requires no special tools for installation and can be installed on wet or dry surfaces or even submerged in water. The product however, can only be installed by trained personnel with factory or representative certification. The manufacturer also requires the installer be recertified annually. In Colorado and the Rocky Mountain States, Linc Energy Systems is a certified trainer.
As with other water-activated composite sleeving systems, A+ Wrap has a smart pig detect-ability element without the drawback of creating cathodic reactions.
Pipe Wrap's A+ Wrap has been identified as an effective alternative to sleeves, welding or complete pipe replacement. With the ever increasing amount of deteriorating pipeline in the United States, I’m sure we’ll hear more about the use of Pipe Wrap to repair or restore our aging pipelines.
