2 ,This product installation convenient,quick,need only one person,a wrench can easily finish pipe repair,no longer needs a large number of workers,can need not stopped completely,not replace pipe pressure of piping of fast repair,the circular arc of the degree requirements for pipe low.

3, The stainless steel material,have anticorrosive,high toughness,hardness and other characteristics.

4 ,Band type of repair clamp have Double sealing ring,aft into tapered,as long as it is within the scope of arms hoop size,where all can realize effective overlap,uniform seal.Sealing ring sruface for fine mesh,can adapt to rough,the irregular surface porous pipes,around the entire pipeling sealing circle form effective.

5, This product use the card buckle type connection mode,and the product scope biggest suitable diameter can be up to 30 mm,can greatly reduce inventory,the product specification can be from DN1500-repair width can be up to 2000mm,almost can meet the size of pipe.

How to choose

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.

Installation Instruction

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.
