LPS’ SealSleeve™ allows for welded joints of steel pipe that has internal thermoplastic liners (such as HDPE). It permits full-penetration welded joints and fast field construction while protecting the weld zone from corrosion with the same plastic polymer the pipe is lined with.
Watch this hydrostatic pressure test to more than 500 bar (7,000+ psi) without a weld – proving that SealSleeve™ prevents liquids from reaching the weld zone.
