3 Page 28 Terms and 1 How to Order Metraflex Metal EXPANSION JointsCertain basic information about the pipeline System is required in order to select and order EXPANSION joints. Data required about the System includes: 1. Maximum Working Pressure 2. Working Temperature 3. Axial, Lateral or Angular Movement 4. Cycles Required 5. Pipe Size 6. End Fittings - Flange, Weld, Groove or Combination 7. Bellows Material 8. Velocities 9. Accessories - Liners, Covers, Tie Rods Metal Bellows EXPANSION joints offer a cost effective alternative to other EXPANSION devices while optimizing the productive life of a Piping EXPANSION joints are designed to last as long as the System .

4 They are maintenance-free. Sealing problems and large space requirements of other EXPANSION devices are eliminated with bellows EXPANSION units meet the Standards of the EXPANSION JOINT Manufacturers Association (EJMA) and military specification MIL-E-17813. Consult factory for specific type and has been supplying industry with quality Piping products for over 40 years. Our reputation for superior products and technical support sets us apart from our addition to non-metallic EXPANSION joints, Metraflex is a supplier of metallic EXPANSION joints, braided hose, EXPANSION loops, pulsation dampeners, and other specialty Piping products using bellows technologies.
