MCL Unitex is a specialist worldwide manufacturer of flexible passive fire protection systems, and has extensive experience in the design, testing, construction and installation of fire seal systems and fireproof enclosures for the oil, gas, petrochemical and refining industries.
The company's experienced engineering staff may also be called upon to design bespoke solutions and to further manage testing and certification.
MCL is a member of the ISL Technology Group.
Blast-proof pipe penetration seals for offshore applications
The Firetex pipe penetration seal is a quick-to-install wrap-around style seal with approvals from A0 to H120, designed to suit any pipe / sleeve ratio from 15mm to 1,067mm diameter.
Our seals have been successfully tested to withstand blast overpressures of up to 1.35bar(g), and will accommodate movement of +/-25mm in any plane as standard, though tailored solutions can also be constructed for applications involving excessive movement on request.
Skirt sealant products for hazardous worksites
Firetex skirt seals have proven to deliver heavy-duty, cost-effective protection in both module-to-module and module-to-deck scenarios.
Our skirt sealing products also provide protection from A0 through to H120 for large rectangular ductwork penetration seals, and have been extensively field-tested to ensure safeguarding from blast overpressures of up to 1.16bar(g).
Fire protection seal systems for offshore oil and gas rigs
Our Jettex range of seal products are enhancements of the Firetex range of products.
The seal systems maintain their hydrocarbon fire protection properties, but are strengthened further with a second element to protect against the additional mechanical forces of a jet fire hazard.
An additional third element is also added in our J120 sealant systems, in order to deliver the most comprehensive protection currently possible on the market.
IMO-approved fireproof enclosures to protect critical equipment
MCL's fireproof enclosure systems are based on a similar material technology to our sealant products, but with the addition of greater silica fibre blanket thicknesses. These enclosure systems are intended to protect critical equipment such as valve actuators in the event of hydrocarbon fire hazards and potential jet fires.
Normally manufactured as a close-fitting jacket, the enclosure is specifically designed to meet client specifications, which ultimately dictate the period of protection and the limiting cold face temperature of the protected item.
Considerable testing has been undertaken over many years and test data has been used as the basis of our predictive software program Calpro. This facility allows us to better analyse customer requirements and predict performance outcomes.
MCL Unitex seal and enclosure systems are independently tested by IMO-approved third party test houses. Throughout testing MCL's systems have maintained their integrity, stability and insulation properties, and accordingly carry certification issued by Lloyd's Register of Shipping, Det Norske Veritas (DNV) and / or the American Bureau of Shipping (ABS).
The Firetex range of penetration seal systems has been subjected to independent blast over-pressure procedures, in addition to hydrocarbon furnace fire testing, and has proved its ability to maintain stability and integrity in blasts of up to 1.35bar(g).
Our systems have also been subjected to jet fire testing and carry further approvals up to J120, following the establishment of an internationally approved test methodology.
ISO 9001-certified fireproofing solutions for marine environments
At MCL Unitex we manufacture our seal and enclosure systems to strict quality control procedures, in accordance with the requirements of ISO 9001. Formal accreditation is held through BSI, which audits our operations annually.
Copies of our certificate and quality manual are available on request and any client audit is welcomed.
Firetex seals and enclosures are multi-component systems made from ceramic and silica high-temperature-resistant cloths, glass cloths, insulation felts and blankets, metal foils and high grade stainless steels.
Silicate fibre blanket products are also employed, which have a patented fibre formulation giving enhanced solubility characteristics in the human body.
These component parts have been proved to be totally innocuous under fire conditions. COSHH data sheets are available on request.
