1.Get well-reading before installing . Check parts to ensure that no damage has occurred during transit and that no parks are missing. Check the dimeter of the pipe and clamp specificions (on label)to ensure you have the proper clamp for your application. 2.Clean and eliminate any irregularities on the pipe ends. 3.On each pipe end, make a mark at a distance equal to half the width of the coupling. 4.Without openging the coupling, slide the coupling over on pipe end. 5.Bring the other pipe end a facing popsition. Make sure the pipes are aligned concentrically and that both pipe ends are curreclty supported. See tolerances indicated on the label. 6.Place the coupling between the marks and make sure that the armor is under the bolts. Do not exceed the torque requirements indicated on the product label. 7.Tighten the bolts alternately and evenly to the required torque. If there are three bolts, start with the center bolt, and begin tightening. Do not rotate the coupling or the pipe during or end tightening.
Confirm the pipe O.D and leak point of which you want to repair. Choose the a right clamp type(single or double band, the width or length etc). Choose the right size belong to the pipe O.D. You are going to repair. E.g When pipe O.D ≤300mm, the clamp you choose should be at 80mm wider away from the leak point. When pipe O.D≥300mm, the length shoud be at least 100mm wilder for covering the leak point. Once urgert repair needed to be doned on lagrg pipes, assemble some small range clamps to one several band repair clamp. 1.Make sure of the exact pipe O.D, which needed to be repaired. 2.Choose two or three small range clamps, make sure the sum of their range is equal to the O.Dof the pipe which you want to repair. E.g when repraiing a DN500mm DI pipe, O.D510mm, choose three DN150 clamps which range is 159-170 to make them be right size for this DN500. 3.The small clamps you use to assemble to a big one is not necessary to be the same size, but it would be better to the same.
