With the ever-increasing requirements for safety, efficiency and cost reduction, waste heat recovery and energy conservation are major concerns within the oil & petrochemical industry.

The ULVA Insulation Jackets (IJS) have been specifically developed with the assistance of the petrochemical industry to help overcome some of the inherent problems associated with traditional insulation systems. Valves, flanges, complex pipelines and instrumentation equipment are often left un-insulated because of the complexity of their shape. Our custom-designed jackets ensure every piece of equipment can be readily covered.

ULVA IJS are designed for use in the harshest of conditions experienced in and around onshore/offshore coastal marine environments. No surface preparation is necessary as the materials used in the jacket construction are inert and will not contribute to corrosion.

Inner & outer Materials
Woven glass fibre fabric (weight at least 440g / m2) both sides coated with 80g/m2 of silver silicone rubber. Fabric certified to BS 476 surface spread of flame.

Insulation Infill
Flexible mineral fibre, foil faced one side with a minimum density of 60 kg/m3. Insulation thickness is determined in accordance with British Standard 5422. For higher performance applications either ceramic fibre or needle mat (E glass) can be used.

ULVA IJS are designed for use in the harshest conditions that can be experienced in and around onshore / offshore coastal marine environments. No surface preparation is necessary as the materials used in the jacket construction are inert and will not contribute to corrosion.

Sewing Thread
A lubricated polyester thread is used on all jackets operating below 200oC.
For temperatures above 200oC either Nomex Kevlar or stainless steel can be used.
All seams are stitched together with a minimum of 6 to 8 stitches per 25 mm.

Side Sealing / Joints / Split Fastening
The use of pull cords, either Nylon or Nomex Kevlar achieves side sealing. All joints or splits are fastened with heavy duty Velcro.

Drainage
All jackets can be fitted with a stainless steel or brass eyelet at the lowest point to facilitate the escape of water ingress and to act as a "tell tale" identification port for leaking fluids.

Speciality IJS
Different materials and construction methods are available for a wide range of environmental conditions and operating temperatures from - 50oC to 1000oC
