Quality Assurance MCL Unitex Ltd manufacture their seal and enclosure systems to strict quality control procedures and practices in accordance with the requirements of ISO 9001. Formal accreditation is held through BSI who audit our operations annually.

Health & Safety MCL’s seals and enclosures are multi-component systems made up from ceramic and glass cloths and felts, metallic foils, silica areogel insulation and high grade stainless steels. Ceramic blankets have been replaced by body soluble silicate formulations and elastomeric and silicone membrane coatings have been tested and found to be totally innocuous under fire conditions. COSHH data sheets may be supplied with all of our systems.

Approvals & Testing All MCL systems are tested by independent, accredited test houses such as the IMO approved Loss Prevention Council at Borehamwood and HSE Laboratories at Buxton. Throughout testing, MCL’s systems have maintained their integrity, stability and insulation properties and accordingly carry certification issued by Lloyds Register of Shipping, Det Norske Veritas or American Bureau of Shipping. Following a rigorous pre-qualification process and a review of our company’s quality assurance credentials and financial stability, MCL have successfully registered with the Achilles Joint Qualification System

Hydrocarbon Fire Testing After 2 hours exposure to temperatures over 1100 degC. Pipe seal and module seal pre-test.

Jet Fire Testing Jet fire testing is the most onerous of all system qualifications. The UK’s Health & Safety Executive Standard OTI 95 634 has been adopted internationally and more recently, the ISO 22899-1 standard dictates our test programmes.

The Benefits of Choosing MCL’s Firetex Pipe & Module Sealing Systems Fully Certified Systems After extensive and successful testing, MCL can offer certified systems to meet A0 & H0 and H60 to H120 hydrocarbon fire conditions with blast overpressures up to 1.35 bar g. Further enhancements qualify these systems for J30, J60 and J120 applications.

The Benefits of Choosing MCL’s Firetex Pipe & Module Sealing Systems Versatile Beyond standard concentric pipe-in-sleeve arrangements, MCL’s designers can provide solutions for eccentricity, bend and tee penetrations, non-sleeve situations and multi-pipe penetrations. A comprehensive guide is available supported by an extensive catalogue of data sheets.

The Benefits of Choosing an MCL Enclosure A Fully Certified System The MCL enclosure systems have been extensively tested and certified and have proven to maintain their integrity throughout the high temperatures of a hydrocarbon fire and additionally, the enormously erosive effects of a jet fire.

The Benefits of Choosing an MCL Enclosure Cost Effective MCL design their jacket enclosures with a close attention to ease of installation. Fire grade Velcro and stainless steel worm drive straps and bands, instead of awkward lacing wires, make the system simple to install with no need for special tools or specialist installer skills. Access panels may be included to enable quick and easy visual inspections.

The Benefits of Choosing an MCL Enclosure Durability The enclosure’s insulation core and jet fire resistant element are totally encapsulated in a tough silicone coated glass cloth giving it exceptional robustness in a wide range of environmental conditions. Nylon quilting studs are used to ensure that insulation materials stay firmly in place throughout the design life of the jacket.

The Benefits of Choosing an MCL Enclosure Versatility MCL’s designers can design their enclosures as jackets directly fitting to equipment or, where the subject equipment is awkward in shape or has control components attached, the enclosure may be designed to fit onto space frames.
