Macoga - Full Face Rubber Flanged Expansion Joints - MAC-FT
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.
Expansion joints expand in length when under pressure. The force created by this pressure is designated as Pressure thrust. Where the pipe supports and anchors are not designed to absorb this force, tie rods across the joint must be incorporated. Tie rods are designed to take the full pressure thrust and tie rods supports are integrated in the flanges (retaining rings) so there is no thrust on counter flanges.
Recommended on most applications to prevent damage due to excessive pipe movements, each rod incorporates double nuts on each end to keep the expansion joint from over elongating and spherical washers to allow lateral and some angular
movements (2 tie rods only).
