FCCU Regenerator Stand Pipe Expansion Joint – Cold wall design Universal with Pantographs. Two ply monitored Inconel 625 LCF bellows. Design temperature: 760 °C (medium) 538 °C (bellows)

METAL EXPANSION JOINTS Thermal growth, equipment movement, vibration or pressure pulsation may generate movement in a piping system. When this movement is not absorbed by the piping system itself, an expansion joint is the perfect solution. An expansion joint is a device primarily formed by flexible bellows used to absorb movements in a piping system while containing pressure and a medium running through it. ADVANTAGES The basic advantages to be gained from using Expansion Joints are: —— Little space required for installation —— Absorption of movements in multiple directions due to their...

QUALITY CONTROL AND TESTING Expansion Joints are thought of as high engineering products to which end our Quality Control Department carefully monitors each of the different steps involved in the production process itself, right from the moment the raw materials are purchased up to the final controls and tests carried out on each Expansion Joint which come off our production line. All the quality controls and tests we carry out are based on our Quality Control Manual, approved under ISO 9001, as well as our Quality Procedures. All our Expansion Joints undergo a series of controls and tests...
