PROTECTION OF BURIED PIPELINES

The results of trials lasting up to 15 years on the corrosion of buried pipes have been assessed by the British Iron & Steel Research Association. Five sites were used, four of them natural soils of more than average corrosiveness and one synthetic corrosive ground. The most important general conclusion from these investigations is that efficient protective coatings of the types which have already been in industrial use for the last 20 years will prevent serious corrosion of buried pipes, provided they are not damaged during transport and laying. Since it is now customary to apply cathodic protection as well as coatings, it can be assumed that good modern practice will reduce the danger of soil corrosion of buried pipelines to negligible proportions. Thus, the material used in making the pipe is of little significance with regards to corrosion and may be chosen purely on the grounds of economy and mechanical properties. Iron and steel pipes were especially well protected against pitting by a 0.25 in. thick bitumen sheathing.
