2 Speed Wrap Stock expansion joints to minimize downtime Speed Wrap Whatever your industry; power generation, board mill, cement, petrochemical, steel, or if any of your process involves high temperatures, can you afford the downtime caused by expansion joint failure? TICO Speedwrap provides a rapid, economic solution to the problem of failed expansion joints. Our many years of experience of supplying this product have taught us that the emergency answer very often becomes the permanent solution. The Speedwrap outer cover is normally supplied in silicone or fluoroelastomer for resistance to high temperature, acidic conditions and the effects of ultraviolet rays, ozone, etc. For specialized services, alternative elastomers are available. In addition to its prime function as a reinforcement, the PTFE layer is a barrier for flue gases containing SO2 and SO3 resulting from sulfur or sour fuels. Only pure virgin PTFE (polytetrafluoroethylene) is used, as other TFE variations do not offer the required temperature/acid compatibility. The inner insulation layer is manufactured from woven, high temperature continuous filament glass cloth, which is impregnated with a high temperature dry lubricant to avoid abrasion from the flexing of individual glass filaments. Pressures: Up to plus or minus 30" W.G. on larger sizes, with proportional pressure limits increased for smaller sizes. Gas Velocities: Up to 10ft/second without flow liners. For higher velocities, or if abrasive particles are present, flow liners are required to maximize service life. Quick and easy to install Increased flex fatigue life over alternative systems No insulation loss due to vibration shakedown Simple and effective method of field splicing Comprehensive stock of standard sizes and models Competitive prices Rapid response to non-standard requirements Technical sales and design support 2

They are manufactured from a twill-woven fabric of stainless steel wire and glass yarn, proofed with a special high temperature resistant compound.

4 Comflex HT/XA Expansion Joints bridge the gap between metallic and non-metallic expansion joints Comflex HT/XA Expansion Joints Comflex HT/XA Expansion Joints and related products are extremely rugged, maintaining good flexibility throughout their temperature range. They are manufactured from a twill-woven fabric of stainless steel wire and glass yarn, proofed with a special high temperature resistant compound. Typically these products are used on gas turbine exhausts (power generation and marine duties), penetration seals, rotary air heater internal seals for power plants and furnace exhausts at steel mills. HT/XA excels under high ambient temperature conditions. HT/XA is the ideal choice to bridge the gap between metallic and-non-metallic expansion joints. Its unique construction allows large movements in confined spaces. 4

James Walker Comflex offers joints and steel parts for most GT applications with joints successfully working in perhaps the most difficult GT applications, for example Siemens 94.3, GE s frame 9F.

This analysis calculates temperature differentials, stress levels and fatigue life based on start up and shut down cycles of gas turbine.

Comflex Elastomer and PTFE Flue Duct Expansion Joints These two materials are manufactured into expansion joints using only a single layer.

5 Comflex Expansion Joints and Bellows Comflex Gas Turbine Exhaust Expansion Joints The James Walker Comflex range of gas turbine exhaust joints and the adjacent steel parts offer unique solutions to problems such as high temperatures, large movements, pulsations, vibrations and water washing. James Walker Comflex offers joints and steel parts for most GT applications with joints successfully working in perhaps the most difficult GT applications, for example Siemens 94.3, GE s frame 9F. James Walker Comflex joints and steel work have been designed utilizing finite element and heat sink calculations. This analysis calculates temperature differentials, stress levels and fatigue life based on start up and shut down cycles of gas turbine. To support the computer analysis calculations, temperature measurements are taken from the field and workshop test rigs. Comflex Elastomer and PTFE Flue Duct Expansion Joints These two materials are manufactured into expansion joints using only a single layer. The elastomers, usually in materials such as Viton from Dupont or Ethylene Propylene (EPDM), are constructed with layers of reinforcement of fiberglass, wire mesh or Kevlar. PTFE, on the other hand, is the ultimate in chemical resistance. It is highly lightweight, temperature resistant and easy to install. Both materials are available in different thickness, weight and have a variety of reinforcements. This style is usually recommended for difficult applications when moisture, chemicals or vibration is present in the system. The robust nature of the product allows it to be used in heavy dust load applications without the need for an internal sleeve. Comflex Fabric Reinforced Bellows These are used primarily as heavy-duty protectors in many different industries. Typical applications include the protection of screw down gear on rolling mills and hydraulic rams on heavy presses, as well as the fabrication of cooling air ducts on traction motors for diesel-electric locomotives. They are also popular as slide covers. Based on heavy-duty elastomer-proofed fabrics, these bellows are a totally vulcanized construction that provides a particularly rugged product. Various layers are preformed prior to the vulcanizing process. This avoids the weakness inherent in bellows fabricated from separate pieces joined by stitching or other mechanical means. Split bellows are available for easy replacement. 5
