Lambda F Box Epoxy - Pyroclad X1

Lambda Fire Box Epoxy - Pyroclad X1

Lambda F Box Epoxy is an insulation system that provides fire protection for valves, flanges, actuators and other equipment.   The Lambda Fire Box is fully tested to meet the strictest on- and offshore specifications for oil and gas installations. This system is built up by insulation material and enclosed by stainless steel (AISI 316). The pieces are fastened with toggle clips in the same material and locked with security pins.

The Lambda F Box Epoxy can be equipped with a drain plug as required for top side installations per NORSOK standard and inspection hatch for easy access to the protected object.  

The system has been tested successfully for blast overpressure at 900 millibar and jet fire with a heat load up to 250kW/m².  

Epoxy Based Jetfire Protection

Pyroclad X1 is the latest breakthrough in epoxy based intumescent fireproofing technology. Pyroclad X1 is designed to provide both jet fire and hydrocarbon pool fire protection for oil and gas installations. This innovative new epoxy intumescent system withstands the harsh environmental conditions of coastal and offshore environments and successfully passed the NORSOK M-501 environmental test program without a topcoat. Its unsurpassed weathering characteristics ensure long performance and integrity of the system throughout the life span of the coating. The Bilfinger Lambda F Box epoxy with Pyroclad X1 has an exterior sheet metal cladding, further enhancing the longevity of the product, and makes it maintenance free.  

The Bilfinger Lambda F Box Epoxy with Pyroclad X1 has been extensively tested and certified in jet- and hydrocarbon fire to IMO 2010 FTP Code Part 3, ISO 22899-Part 1 as well as explosion tests.

Design and Test results  

Lambda F Box Epoxy with Pyroclad X1 are easily installed and are removable to allow for inspection and maintenance. The toggle clips allow for quick and easy installation without the use of tools. The stainless steel surface is maintenance free, and the inside is lined with Pyroclad X1. In case of a fire, Pyroclad X1 material reacts to protect the object. The Pyroclad X1 material is moisture resistant, with an absorption rate of 0.2%.  

Lambda F Box Epoxy with Pyroclad X1 is tested with drain plug and inspection hatch meeting industry best practice design.
