MAC-F, MAC-FT, MAC-FP, MAC-FC, MAC-FB, MAC-FR & MAC-O Series
High quality custom-made expansion joints supplied with split or fixed steel backing flanges. The full face flanges are integral with the body of the joint and drilled to conform the bolt pattern of the companion flanges of the pipe line.
Rubber bellows: Reinforced EPDM, EPDM HT, Nitrile, Spec. Nitrile, Nitrile white, Hypalon, SBR, Viton®, Chloroprene, etc.
Flanges: shot-blasted and painted carbon steel as standard. Also available in hot dip galvanized carbon steel, stainless steel, etc. Drilled to EN, ANSI, AWWA, JIS standards or any specific dimension.
For vacuum applications, an internal vacuum ring is incorporated.
MAC-F and MAC-FT can be supplied with one or more arches. Dimensions from DN 15 to DN 6000.
These expansion joints can be fabricated as a single and multiple arched elements with flanged connections, plus a system of articular supports that allow for angular movement in one plane only.
The hinged mechanism is designed to accept full pressure thrust.
These expansion joints can be fabricated with more than one convolution.
These units do not allow axial movement. However,some types of hinged systems can be provided with slotted holes for the hinge pins, to allow limited axial displacement. The “slotted hinge” units cannot resist the pressure thrust forces and therefore proper anchorage must be provided.
