LPS Products General Brochure

Carbon steel pipe provides optimum strength and ductility for pipelines. However, the leading cause of steel pipeline failure is internal corrosion. LPS’ mission is to make pipelines last longer by making internally lined/coated pipelines easy to construct with consistent joint quality.

LPS technologies permit fast and standard construction methods for steel pipe with internal linings and coatings:

FlexSleeve^® & CCB^® Sleeve are internal weld sleeves used for pipe that is internally coated with thin-film coatings such as epoxy or polyurethane. They are inserted into joints during new pipeline construction and protect the weld zone from corrosion. They prevent the need for manual or robotic internal joint coating, which significantly slows down construction and often suffers from quality issues. Weld sleeves are also a good alternative to costly and leak-prone bolted flange connections.

The innovative LinerLock^TM system combines the corrosion-free benefits of non-metallics with the high-pressure strength of carbon steel pipe. Shop-lined steel pipe arrives in the field with thick, flexible, thermoplastic liners ready to construct without any subsequent field-lining steps. Standard girth welds or mechanical interference fit (MIF) joints are used. LinerLock^TM is a complete liner system, including fittings and practical methods for field cuts/tie–ins.
