Hydrocarbon and jet fire protection boxes and jackets
The Lambda ‘F’ products have been tested and certified to withstand hydrocarbon and jet fire with temperatures ranging from 250kW/m² to 350kW/m² (IMO 2010 FTP Code Part 3, ISO 22899-Part 1 and Extended OTI 95634).
The ‘F’ product range is made with high-performing materials, including:
- Polymer-based insulation material, powered by Favuseal™
- Intumescent epoxy-based material: carboline pyroclad X1
- Traditional insulation materials
The Bilfinger Lambda ‘F’ jet fire boxes are completely maintenance-free, which reduces the overall total operation cost compared with similar products.
The ultra-slim design is also featured in the Bilfinger Lambda ‘F’ pipe product, which is an innovative solution for insulating pipes in confined spaces. It has been tested and certified by DNV-GL.
The products are fully tested with inspection hatches and drain plugs, and include extensive documentation such as mass, surface area and operating temperature. The hydrophobic materials effectively reduce corrosion under insulation.
Pipe penetration seals for bulkheads and decks
The Lambda ‘F’ pipe penetration seal (PPS) is a patented, customisable and flexible insulation system designed as a fire and gas seal for bulkheads and decks.
It is fully certified by DNV for Classes A0, H0, A60 and H60 and tested for jet fire with a heat load of up to 250kW/m² (ISO 22899-Part 1). The Lambda PPS is a flexible, easy-to-install solution that facilitates pipe inspection and maintenance.
Protective fire jackets for flanges and bolts
The Lambda ‘F’ BoltCare is a flexible jacket designed for fire protection for flanges and bolts, where the pipe itself does not require insulation.
The BoltCare jacket is tested for jet fire with a heat load of 350kW/m² (OTI 95634) and extreme weather. This is an advanced and flexible product regarding flange inspection and maintenance.
Acoustic insulation for high-frequency environments
The Lambda ‘A’ sound-reduction solution consists of both curtains and an installation system. The acoustic insulation can also be applied as flexible jackets for valves, flanges, pumps or other equipment.
Noise levels are reduced by up to 20dB in high-frequency environments and the solution is tested and approved in accordance to NORSOK Classes 6 and 7.
Cryogenic insulation solutions
The Lambda Cryo Box is a prefabricated cryogenic insulation system that is designed and tested to insulate valves and flanges with operating temperatures down to -163°C / -261°F. The solution can be removed and reinstalled multiple times, which means significant cost savings.
The Lambda Cryo Box is customised and assembled at Bilfinger’s workshop and its installation requires no heavy work or hot work onsite, resulting in the involvement of fewer personnel, a more efficient installation and a safer working environment.
The solution applies to NORSOK Classes 2, 4 and 9, and is also available in combination with Lambda fire box or jacket for equipment requiring Class 5 insulation.
Thermal insulation systems
The Lambda multipurpose thermal insulation jacket is used as both thermal, sound and personnel protection for NORSOK Class 1, 4 and 6 applications. The solution can be used in various production environments such as power plants, process, marine, and oil and gas industries.
Bilfinger’s customisable thermal insulation system can be delivered as flexible jackets or boxes in stainless-steel. Its insulation material and thickness can vary, depending on the client’s requirements.
All seams are sewn with Kevlar thread and sealed with silicone, which prevents leakage.
Combined fire, acoustic, cryogenic and thermal solutions
Lambda has accumulated experience with combination solutions, as a result of more complex requirements involving insulation for several NORSOK classes or other standards for equipment.
The challenge with combination solutions is often related to meeting all requirements, while keeping the insulation thickness at a minimum.
