LOW MID CORR SERIES
MDC metal bellows are known for their superior flexibility. The bellows are able to compensate for large movements in the axial, lateral and angular direction or mechanical vibration. MDC bellows ensure the lowest possible forces combined with extreme longevity.
This makes MDC expansion joints ideal components that minimize stress and strain in pipes and extend the life of any system exposed to elevated and varying temperatures.
MDC flexible bellows connectors ensure that suction and discharge nozzles of pumps and compressors are protected from high forces and moments and that vibration is not transmitted into the piping system. This increases the durability of rotary equipment and reduces noise level throughout the entire system. Mark David Canada Inc. offers standard LOW/MID corrugation bellows expansion joints.

They are an economical solution to compensate for moderate to large thermal expansion in various piping systems. The highly flexible bellows allow movements in axial and lateral directions and/or angular rotation.
LOW/MID "CORR" expansion joints are designed in two pressure ratings as standards: 50 and 150 psig. Standard bellows are made of T321 stainless steel in diameters from 2.00” to 24.00” and are offered in SHORT and LONG styles. RFSO, plate, and Vanstone flanges as well as weld ends are part of standard design. Should your application call for corrosive media, we can supply bellows in T316 SS, Inconel, Incoloy or Titanium.

Higher than standard pressure ratings are also available with thicker or multi-ply bellows. Our shop can provide you with virtually any special connection, such as special drilled round flanges, square flanges, etc. Various accessories include flow liners, external shroud (cover), rods (limit, tie or control). See “Special Joints” section of this site for further examples of custom expansion joints.
