MCL Unitex Limited are specialist manufacturers of flexible and rigid passive fire protection systems and have extensive experience in the design, construction and installation of fire seals and fireproof enclosures for the oil, gas, petrochemical and refining industries worldwide. Their pipe penetration seals are in use across the globe and have a reputation for reliability and longevity.
Firetex seals and enclosures, and their metallic enclosure systems are multi-component systems made up from high temperature resistant cloths, glass cloths, insulation felts and blankets, metal foils, silica-aerogel panels and high grade stainless steels. Silicate fibre products are employed which have a patented fibre formulation giving enhanced solubility characteristics in the human body.
To provide protection against harsh environments such as those experienced offshore, MCL’s flexible systems have an elastomeric membrane coating which has been tested to DIN53436H. MCL’s seal and enclosure systems are independently tested following the hydrocarbon fire time vs. temperature curve for a period of two hours in accordance with the Department of Energy Specification – Issue 1: 1990, adopting the appropriate procedures of the exchange of notes and the International Conference on the Safety of Life at Sea (SOLAS), as amplified by the International Maritime Organisation (IMO). Throughout testing, MCL’s systems have maintained their integrity, stability and insulation properties and accordingly carry certification issued by either Lloyds Register or Det Norske Veritas. In addition to fire testing, the Firetex range of penetration seal systems have been subjected to independent blast over pressure testing and have proved their ability to maintain stability and integrity in blasts of up to 1.3 bar g.
