Expansion Joints Metal
Metal COFLEX®M expansion joints represent the most widely items used in the industry, although their ideal use is on piping connected on one side to a moving part and on the other side to a fixed one where neither rubber nor fabric joints can be used.
COFLEX®M joints can be manufactured using the most suitable metal material, which could be either carbon steels or a wide choice of stainless steel, or Monel®, Inconel®, Hastelloy®.
COFLEX®M expansion joints can be made starting from DN10 to DN8000, round or rectangular shaped.
Most of this type of joints are made by multilayer walls that once assembled undergo a plastic deformation allowing them to get the characteristic convoluted shape.
Metal COFLEX®M expansion joints can be installed on:
· Piping conveying very low or high temperature flui
· Conveyance of toxic or explosive gaseous fluids
· Systems where there is high pressure saturated steam
· Turbine and diesel engines exhaust duct
· Turbine and boilers exhaust duct
· Any kind of system/installation, where temperature, expansion and safety must be safeguarded.
According to the latest Directive 97/23/CE (directive PED) about pressure equipment, customers are to fill in the appropriate attached form PED COFLEX®M allowing Cofi’s Engineering Dept. to submit the most appropriate offer.
For each joint, a calculated theoretical lifetime is expected according to a stress analysis performed by means of proper software that fulfills the E.J.M.A. standards (Expansion Joint Manufacturers Association).
Furthermore, COFI Ltd. can supply Metal COFLEX®M expansion joints already approved by Rina and other Shipping Registers.
