The body material can be ductile iron ,carbon steel or stainless steel.Gasket material is EPDM or NBR.Tie bars can be gal.steel ,hot dip gal.steel,Stainless steel or as per client request. Sr.No.NameMaterial1Long bodyDuctile Iron2Short bodyDuctile Iron3RetainerDuctile Iron4GasketEPDM/NBR5Tie rodsCS/SSManual for dismantling jointInstallationThe installation will be made using the tie rods.Tie rods must extend until the flange of the valve or of the piece connected to the dismantling joint.Bolts used for the assembly must have the same metric and quantity of DN that flanges used.Its length will have to be sufficient so that the ends of the nuts and bolts exceed at least of 1centimeter of the external bolts.Installation process:Step 1:It is advised to check the length of final assembly fo the dismantling joint,so that it is closest to its nomial measurement,to facilitate the seembly and the disassembling of this one.Step2:The correct position for the assembly of the dismantling joint will be,water downstream from the female part and water upstream of the male part.Note:for pipes with a water direction in the two sides(pipes of discharge),the dismantling joint will make the sealing in the two directions when the flow of water is contrary to the assembly indicated above,the pressure loss will be superior.Step3: To unscrew the bolts which tighten the intermediate flange as well as the internal bolts of the flanges of connection,to check that the male/female sliding is slowly made in order to avoid any stretching and /or scratch between the fixed and mobile parts(pyramidal joint,male and female).Step 4: To place the dismantling joint in its final position,making sure that the position of the holes of the flange coincides with the position of the holes of the pieces to connect.Note:The maximum tolerable angular deflections for the flanges(parallelism) of pieces to be connected will not exceed the following value of 0.25°X1000/DN considering only the connection which is carried out with the  tie rods does not enable a greater deflection than that caused by the tie rods with the holes of the flanges.Please more details,please contact us .Our Process for dismantling joint production is as belowWe Produce our product strictly according to ISO9001 quality control system,and we have WRAS ,DVGW, ,ISO14001 certificate for powder,and WRAS certificate for EPDM gasket.Photos as below are for your referenceour Package is sea worthy polywood box or pallet,photos are as belowWe control our quality according to ISO9001 ,photos as below is for your referencewelcome your enquiry ,we will do our best to support.
