Lambda Pipe Penetration Seal (PPS)
Lambda Pipe Penetration Seal (PPS) is a tailored and flexible insulation system designed as a fire and gas seal for pipe penetrations installed in bulkheads and decks. It is fully tested and certified to meet the strictest on- and offshore specifications for oil and gas installations.
This system is patented to Bilfinger Industrier.
Lambda PPS is a tailored pipe penetration seal and certified by DNV for classes A0 and H0, A60 and H60. The system has also been tested for jet fire with a heat load of 250 kW/m² (ISO 22899-1). The Lambda PPS is flexible, easy to install and makes pipe inspection and maintenance efficient. This solution is also tested for extreme weather according to NORSOK and in cooperation with DNV. All seams are sewn with Kevlar thread and sealed with silicone, to avoid water ingress.
Our PPS system is built up by a core of insulation material and stainless steel foil (for jet fire rated PPS), enclosed by a custom-built silicone fabric. The pieces are joined with Velcro in the overlap and the system is secured with stainless steel bands, ensuring the integrity of the insulation properties.
In addition to exceeding functional requirements, all Lambda products are designed for quick and easy removal and re-installation with a minimum use of personnel and tooling.
