Expansion Joints are a combination of grooved couplings and short nipples, joined in tandem to provide increased expansion. The nipples are preciselygrooved to provide full linear allowance at each joint.
Grooved pipe couplings and fittings are used to join and pipes in both wet and dry system. They provided some flexibility in terms of movement and deflection to the piping system. The concept of grooved coupling was invented in 1925 when Victaulic design the first mechanical coupling.
We can provide all types Victaulic couplings. Designed to make installation and connecting your Reverse Osmosis and Ultra Filtration systems fast and easy. Reducing field man-hours to a minimum. Victaulic couplings come in a variety of styles and with any type of gasket to suit your needs. Style 75 is a flexible coupling designed for moderate pressures up to 34.5 bars. Style 77 is recommend in system with working pressures up to 69 bars while still allowing flexibility to absorb movements in the system. From brackish or seawater intake to membrane assembly and water distribution.
