Flexible Fire Protection Jackets - Advanced Insulation

1 Flexible fire Protection Jackets applications in the oil, gas and petrochemical industries require Flexible , user-friendly fire Protection systems that can be easily fitted without specialist tools. For ease of maintenance such systems should be simple to remove and refit, yet be of durable construction and able to withstand the rigours of service duty. ContraFlex is a range of tailor-made Flexible Protection Jackets developed by Advanced Insulation . ContraFlex is designed to provide high performance thermal Insulation and Protection from jet and / or hydrocarbon fire to equipment which requires frequent maintenance access.

2 As a part of the initial survey we offer to dismantle and dispose of any existing fire Protection in order to fit ContraFlex . DesignThe ContraFlex design team utilises Lectra software integrated with Carlson proprietary software for 3D product realisation and the operation of 32 cutting table installed in a mobile production unit. ManufactureContraFlex is manufactured in the form of a jacket, usually 50-61 mm thick. The thickness of the jacket can vary to suit the requirements of the application. Manufacture can be undertaken either at Advanced Insulation s facilities or, where appropriate, at a project site anywhere in the world. The ContraFlex team is headed up by a principal fabrics engineer who has over ten years experience in the manufacture of the Flexible Jackets and an understanding of their applications within the oil and gas industry.

3 InstallationFull installation instructions are supplied with each jacket, detailing how the components fit together around the protected structure. The Jackets are held in place by simple fastening systems, such as stainless steel fixings and / or Velcro straps. Both ContraFlex and the fixings are designed to be easily removable for maintenance, yet are suitable to withstand exposure at the site.

4 These PFP requirements form an integral part of fire and explosion and mitigation philosophy.

5 J120H30H60H60H1204 Process EquipmentWhile the individual operators standards vary, the manufacturers specify that the maximum operating temperature of pneumatic and hydraulic valve actuators is 130 C and of motor operated valve actuators 110 C. The ContraFlex Jackets have H30 temperature rise of 11 C and J30 temperature rise of only 30 C. This allows for ambient temperature of equipment of over 55 C and the maximum temperature of equipment in direct sunlight can reach 85 C. StructuresContraFlex is typically used to protect riser clamps, pipe supports and pipelines to ensure that the surface temperature is maintained below 400 C during a J60/J120 event. The bespoke design and fixings enable ContraFlex Jackets to be secured to large structures when required.

6 Each segment of a jacket is designed to be easily handled by one or two people and incorporates lift points to enable individual segments to be lowered to the ground. Weight of each segment is clearly marked on it. 3. Electrical & InstrumentationContraFlex fire Protection for electrical junction boxes is designed to restrict internal temperature rise and to protect the junction box from overheating.

These tests were applied to both tubular and planar test specimens made of carbon steel and protected with ContraFlex passive fire Protection system. The test was undertaken in accordance with the International Standard ISO 22899-1 Determination of the Resistance to Jet Fires of Passive fire Protection Materials, Part 1: General Requirements.

9 The thermal and mechanical loads applied to the material by the jet fire as defined in this standard are similar to those created in large-scale jet fires resulting from high-pressure releases of natural gas. The facility used for this test is independently certified by Lloyds Register for compliance with BS EN ISO/IEC 17025:2000. The ContraFlex jet fire test was witnessed by representatives of Lloyds Register. Key ResultsContraFlex J120 test specimen was subjected to a propane jet fire with an average mass flow rate of kg/s-1 The maximum temperature rise recorded in the specimen by the end of the test was 123 C. After the test, ContraFlex jacket appeared to have suffered only minimal damage to the outermost layer of material.
