Manholes and Jointing Material

All flanges need to be connected using bolts and nuts as well as gaskets. PVC Pipeline Services supplies both.

Every underground chamber needs to have a manhole cover and frame. This is as per SABS standards. We supply both in a variety of sizes, as well as in two different types of material: choose from ductile iron or polymer concrete manhole covers and frames. Ductile iron is particularly strong, which makes it a good choice for manhole covers and frames. Manhole covers are required to handle excessive loads in terms of weight and traffic, which makes it imperative that they are durable and strong.

Where water supply networks and piping systems are concerned, a gasket is a sealing material that is placed between connecting flanges. They will maintain the leak-proof sealing in all operating conditions, with different types of gaskets available to achieve the seals. They seal irregularities of the face of the flange preventing leakage from the flange joint.

All manhole accessories need to be fully compliant with SABS standards by law. This is why PVC Pipeline Services is here to ensure they meet the proper requirements.

In order to be SABS compliant, underground chambers need to have both a manhole cover and frame. We supply them in a variety of sizes, as well as in two different types of material: choose from ductile iron or polymer concrete manhole covers and frames. Polymer manhole covers are made from a composite material that is bound using resin and fibreglass.
