compression coined with corrosion of pressure rings or collars or the bolts may aggravate the breakdown. Following procedure may be followed: 1. Internal mobilization. 2. Detection of pipe failure: Inspection of site 3. Notifiion of interruption in water 6.

hodic Protection: This provides the protection to the underground pipe from the corrosion by electrolytic process in subsoil water, whenever in e-m-f is induced’ in it (when pipe material is a good conductor e.g. carbon.

All water supply systems use a coination of pipes (of different dimensions and materials), valves and outlets to deliver water to building users. Some water supply systems also use storage pipess and pumps. Designing a water supply system involves getting all of these elements right so that clean water is delivered to the user at the appropriate rate and temperature.

Corrosion control for offshore pipelines is typically achieved with a coination of pipe coatings supported wilh hodic protection to cover coating holidays or defects. The nature of offshore pipelines dictates that the most cost effective and reliable method of providing the hodic protection component is the use of zinc or aluminum alloy bracelet anodes.

Corrosion from this source may be of the pitting type, the pits being filled with soft, foul-smelling sulphides. The microbiologist can identify the bacteria from samples of water and corrosion products. In estuaries and harbours where water is polluted with organic

Water Main Installation Pipe Assely • Pipe laid in trench at design grade and asseled using come-along or pry bar • However typically pushed together with excavator, there is a risk pushing the pipe into the bell to far and damaging the bell • On PVC pipe

PVC is invulnerable to underground external corrosion as well as internal pipe corrosion. This eliminates the need to specify corrosion protection methods that have become standard procedure for piping. With PVC, long-term durability is not compromised.
