Insulation and Fluid Sealing Innovations
Submitted by: Dan Alexander, Atlantech Distribution
Like many well established industries, the marine insulation and fluid sealing industries usually lack the glitz and glamour of newer trendier industries. This is particularly true as it relates to Navy ship repair and well established Mil-Spec’s that can create barriers to the introduction of new products. It still remains imperative as an industry that we continue to be aware of new developments and technologies that have the potential to provide our customers with better performing, longer lasting products. To this end the following information is presented for your consideration.
Insulation and fluid sealing products are closely linked to energy conservation and personnel protection. As energy costs rise the need to conserve or obtain a better yield from every unit of energy becomes increasingly relevant. Aboard ship a multitude of pipes carry hot, cold and combustible fluids and gases that provide vital resources to ship personnel and equipment. Real cost savings can be realized if these pipes and vessels are insulated properly and the fluids they transport are properly contained. Unfortunately unintended human contact with unprotected pipes or vessels, as well as leaks and spills from pipe flanges and joints can result in serious bodily injury. Therefore, the proper application of these products although typically overlooked are essential to the safe and efficient operation of a ship. Fortunately we have highly qualified suppliers and contractors in our area that offer the most up to date solutions to meet the strenuous demands of our market.
One new development in the insulation industry is Eslin a product developed by Visionary Industrial Insulation as an alternative to calcium silicate pipe cover and board. The manufacturer claims this product will reduce heat loss by 40% when compared to calcium silicate in hot equipment and piping applications because of its exceptionally low thermal conductivity. The result is a material that is lighter and requires less space while providing equal or better performance. This is achieved through a manufacturing process that combines specially processed needled mat and inorganic binders to form a non-combustible, high temperature insulation ( up to 1400 F)with superior thermal performance and excellent fire resistant properties. The product is compliant with the following; MIL-STD-1623, MIL-I-16411-F, MIL-I-24244C.
New from Garlock Sealing Technologies is Therma-Pur style 4122 gasketing material designed for use in high temperature applications (1800 F). The material is able to withstand high temperature whether continuous or in thermal cycling conditions. Additional benefits include; easy release from flanges making removal of gaskets fast and easy. It also resists water and provides electrical isolation thus reducing the possibility of corrosion between flanges made of dissimilar metals. Specific applications include marine and land based exhaust systems, incineration processes and turbocharger equipment.
