Product Introduction & Specifications of Ductile Iron Flange Adaptor

Flanged Adaptors are designed for pipelines, As a wide tolerance system.

It will fit most standard pipe materials and therefore dramatically reducesthe number of dedicated Flanged Adaptors which need to be stocked for maintenance purposes.

It is suitable for steel, GRP, PVC, PE, Ductile Iron, Cast Ironand Asbestors Cement.

When connecting PE pipes, It is important that pipe inserts are fitted to the PE pipes.

Packing and Installation Instructions of Ductile Iron Flange Adaptor

1. Examine the pipe ends and ensure they are round, smooth, free from bulges, dents and score marks and within the outside diameter range given on the adaptor label. Weld beads mustbe ground flush maintaining correct surface profile. Ensure that pipe ends are free from scale rust or any loose debris or other surface defect that may affect coupling performance.

2. Check grade of gasket is suitable for conveyed medium.

3. If the adaptor has T bolts between the main flange body and end ring ensure that their heads are correctly located in the recesses in the back flange face.

4. Place the adaptor onto pipe end. Adjust the setting gap between pipe end and adaptor as necessary. Ensure that the pipe end is concentric with the bore of the mating flange.

5. Fit flange gasket and ensure it is concentric with the flange connecting bolts, procedures. Bolt the adaptor to the mating flange using standard bolting.

6. Tighten diametrically opposed T bolts/studs giving the nuts one or two turns at a time to thoroughtly draw up the end ring evenly. The nuts must be tightened, working around the flange adaptor as many times as necessary. On completion, radial gap between pipe and flange adaptor end ring should be even all the way round. Rubber may be seen to extrude into the gap.
