Macoga - Αντικραδασμικά - MAC-FR / Rectangular
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.
Rectangular Expansion Joints are generally designed for low positive pressure and vacuum applications in the power, chemical, petrochemical, and steel
industries.
These expansion joints can be fabricated with single and multiple arches. Due to the fact that there are no standard dimensions for rectangular pipes, each rectangular expansion joint is custom designed. They can be built with more than one convolution.
Regardless of accessories, such as tie rods, hinges, liners, covers, etc. these models absorb all the movements in any one length of piping, but are mainly used to absorb axial movements. Like circular expansion joints, unrestrained units do not contain pressure thrust so adequate anchors and guides must be provided, and they can be used only in piping systems that incorporate correctly designed anchors and pipe alignment guides.
