PetrochemicalSIG Technical Insulation has invested in stocking a wide range of products to meet the high standards of the Petrochem and Chemical industries.
Insulation requirements on Petrochemical plants are very diverse, from large specialised storage tanks, process heaters, thermal oxidisers and incinerators with applications across a wide temperature range.
Over the years, we have supplied material to all of the UK’s Petrochemical plants, from Sullom Voe in the Shetland Islands to Exxon Fawley and BP Wytch Farm in the South of England.
Power GenerationThe secret to successfully supplying the Power Generation industry is having the right stock on the ground when required – especially during annual shutdowns.
Here at SIG Technical Insulation we are committed to having a constant dialogue with our customer base, this has allowed us to demonstrate our capabilities in this area time and again, ensuring our customers get the right product at the right place at the right time.
SIG Technical Insulation can offer advice and the supply of products for all types of boilers. We have products that are designed to withstand corrosion, erosion and thermal conditions that are experienced in this environment.
SIG Business Support SIG has teamed up with a number of carefully selected third parties to offer our customers a combined, unique and market leading package of financial services. SIG customers can exclusively benefit from discounted rates and in some cases privileged access to business enhancing products not freely available elsewhere to help secure additional finance, increased cash flow and enhanced internal risk processes.
Visit us today at: www.sigfinancetools.co.uk to find out how you can achieve competitive advantage and ensure your business is protected and financed for future growth.

Original Equipment Manufacturers (OEM)AluminiumSIG Technical Insulation has for many years been supplying materials for the manufacture of such equipment as Boilers, Kilns, Ovens and Furnaces.
Again SIG Technical Insulation has demonstrated capabilities in solution providing and innovation.
A number of products including Aerogels, Microporous, Vermiculite, Refractory bricks, Electrical elements, Rock fibre are readily available at our sites.
Non-ferrous products are in high demand and the industry continually strives to increase productivity whilst reducing running costs by means of process and efficiency improvements. SIG Technical Insulation are ideally set up to support both end users and contractors in achieving these improvements with an offer of materials for melting and holding furnaces as well as the casting process.
Included in our range are products with superior non-wetting properties.
Iron and SteelOffshore and MarineSIG Technical Insulation provides a number of Refractory and High Temperature materials to assist steel makers in the production of their products.
SIG Technical Insulation can offer a local service to these sites.
Products range from Alumina silica bricks, Insulating bricks, RCF & (AES) Wool products, Microporous and Monolithic products.
The importance of safety is paramount within the Offshore and Marine industries, SIG Technical Insulation have the expertise and range of products to insulate and protect the many and varied applications found Offshore, including Cryogenic, High Temperature and Personal Protection. Fire Protection in this Offshore environment is always taken very seriously, with many authorities involved in the certification of bulkhead and deckhead insulation, such as IMO/SOLAS, Lloyds, Det Norsk Veritas and the British Admiralty.
Other applications include exhaust insulation, hydrocarbon fire insulation, fire seals and drench systems, as well as the insulation of accommodation. SIG Technical Insulation has been the leader in this field for many years. We have introduced many innovations to the Offshore market, in particular where corrosion under insulation is a serious problem and time saving solutions are at a premium due to the additional costs associated with Offshore contracts.

“Alkaline Earth Silicate” (AES) Wool Products
For more information, please visit www.sigtechnicalinsulation.co.uk
(AES) Wool Products are manufactured by melting a mixture of calcia/magnesia & silica, and blowing or spinning the melt to produce fibres. These fibres can then be needled together, forming a mechanically strong binder-less product or mixed with a binder and pressed to form boards. They offer products with similar performance to Refractory Ceramic Fibres without the potential health and safety concerns.
(AES) Wool Products have a classification temperature of up to 1300°C; the classification temperature is the temperature at which the product suffers a permanent shrinkage of less than 4% over a 24 hour period.
The fibres have been designed to have low bio-persistence to encourage their breakdown within the body if inhaled or ingested. Exonerated from any carcinogenic classification under nota Q of directive 97/69EC.

UP TO 1100ºCCalcium Silicate is a traditional insulation material that has been used for many years. Its main benefits are its relatively high temperature limits (depending on type), its strength and appearance and the fact that it can be cut or moulded into a wide range of shapes and components for hot insulation uses.
As well as being available in pipe sections, lags and slabs, this type of material is also available in a cementitious form for direct application to complicated shapes or for finishing uneven surfaces.

Furnace InspectionsSIG Technical Insulation provide a variety of furnace inspection services. With our knowledge of modern refractory materials and installation techniques we can help you improve efficiency, reliability or even just to reduce cycle times.
Thermographic SurveysBy means of an external furnace survey utilising a Thermographic camera or gun we can assess the energy loss through the casing, advising current and future potential problems within the furnace.
This allows an easy calculation to be made showing energy wastage and potential savings in both energy and money.
Heat Loss – Actual LiningHot Face 650°C Emissivity 0.9 Wind Speed 0.00 m/s Ambient Temp 20°C
Total Heat Loss = 26926 Whr
Heat Loss – New Lining Hot Face 650°C Emissivity 0.9 Wind Speed 0.00 m/s Ambient Temp 20°C
Total Heat Loss = 12348 Whr
This is a reduction of 54% in Energy Wastage
Refractory InstallationsWe work alongside a network of accredited partners to provide a full installation service for the majority of applications and Industries, providing a one-stop solution from Thermographic Survey, Inspection, Supply through to Installation and Sign off.
