1.DetailsFlexible Pipe Coupling for Ductile Iron PipePipe fittings are designed to accommodate plain ended pipes with different outside diameters.Thus reduces the need for stockholding,as one single coupling is able to connect different pipes materials suchas ductile iron ,Steel,AC and others.Benefit:Perfect sealing GasketThe sealing gasket with good circumferential ribs which provides a easy slide fits for maximum sealing even on pitted,scored or corroded pipes.Excellent coating protectionThe normal painting for universal fittings is RAL5017 fusion bond epoxy coated powder which with good anticorrosion characteristic,and the bolts and nuts are Dacromet,which with good anticorrosion, thermostability characteristic than Zinc Plated.Easy to InstallThe uni-fit range is supplied with carriage bolts, only need a torque wrench,from one end to tightened the nuts to finish the installation, simple and save time.Simple to fitAvailable as standard and long sleeve versions,the uni-fit range allowing for greater cutting tolerances and a greater pipe insertion depth which simplifies the installationEconomic designSuch concave design can reduce the weight of the flange adaptor,so do the economic cost for same products.Features:1.Ductile Iron GGG50 material with FBE coated.2.PN10,PN16 working pressure.3.Equipped with galvanized steel bolts,nuts.4.EPDM or NBR rubber seals5.High Tolerance Mechanical Pipe Fittings.6.Angular deflection +/- 6°7.Other size and range are available on request.2.Data SheetMaterial Specification:PartsNameMaterialGlandDuctileIronGasketEPDM/NBRCenterSleeveDuctileIron/SteelDimensions (mm)SizeRange(mm)BoltingsxNo.InchDNMinMax11/2"DN404858M12x22"DN505973M12x421/2"DN657285M12x43"DN8088103M12x44"DN100109128M12x45"DN125132154M12x46"DN150159182M12x47"DN175192210M12x48"DN200218235M12x410"DN250266291M12x612"DN300315332M12x614"DN350374391M12x816"DN400417437M12x818"DN450480500M12x1020"DN500526546M12x1224"DN600630650M12x12Company Profile:Our Own Factory and 50 Partner Factories Increase Your SelectionValves, pipe fittings and machined parts all in one place.You source a lot of pipeline products and machined parts from China.
