Steel pressure pipe - water supply

Steel pressure pipe - water supply

Steel pressure pipe - water supply

(OP)
we are considering a steel pipeline with pressures of up to 40 Bar and diameters 600 to 1500 mm. The pipeline will be buried and carry raw water.

I am looking for advice on the need for thermal expansion, pipe jointing and corrosion protection.

Can anyone point me at any good web sites or publications.

RE: Steel pressure pipe - water supply

Sounds like you need prestressed concrete cylinder pipe--a thin steel "leakproof" spiral-welded liner, protected by a layer of cement on the ID and concrete on the OD, with a spiral wrapping of high-strength steel wire for the prestressing.

The concept of this method is very good, but there have been numerous field failures caused by corrosion/other problems of the prestressing wire.  

The problems are easily solved if care is taken and the pipe production is monitored by a knowledgeable person.
