THORBURN FLEXIBLE PIPING SPECIALIST EXTRA-FLEX MODEL "EFS/EFD" EXTERNALLY PRESSURIZED EXPANSION JOINTS COMPARE THESE ADVANTAGES ■ Up to 16" axial movement ■ Leak-proof and no packing ■ Maintenance free ■ Design pressures up to 1000 psi ■ Temperatures up to 1500ºF Fully assembled Thorburn Extra-Flex Model EFS Typical schematic of Thorburn Extra-Flex externally pressurized axial expansion joint system. Shown is Thorburn Model EFS single bellows design. Cross-sectional view of Extra-Flex EFS expansion joint system APPLICATIONS ■ Replaces costly equalizing expansion joint system ■ Replaces space confining pipe loop ■ Replaces maintenance required slip joints ■ Ideal for long pipe run steam lining that require high pressure/ temperature containment with lots of axial movement What is Thorburn Extra-Flex expansion joint system? Thorburn Extra-Flex expansion joint system is designed so that the pressure is external to the convolutions. This unique construction eliminates squirm, thus long axial movements are made possible even at higher pressures and temperatures. THORBURN EXTRA-FLEX ADVANTAGES Full thickness cover Extra-Flex cover contains the full line pressure of the system, thus if bellows failure were to occur, the media could not escape radially outward and harm personnel in the area. Self draining Extra-Flex convolutions make it impossible for media collection in the bellows to cause any corrosive attack on the bellows element. The sediment or residue collects at the bottom of the casing for easy venting. Purge and drain connector Extra-Flex vent to assure fluid filled line and allow draining of any sediment. Reduce installation costs Extra-Flex bellows element is completly enclosed and there are no critical surfaces that require special precautions when handling the expansion joint during installation. None of the slip joint disadvantages Thorburn's Extra-Flex does not require maintenance or need lubrication or repacking, therefore making it ideal in areas where accessibility is limited. Page 53
