Steel pipes
The Construction of these pipes is similar to wrought iron pipes, it is occasionally used from main lines and at such places where pressure are high and pipe dia is more. Steel pipes are more stronger, have very light weight and can withstand high pressure than cast iron pipes. They are also cheap, easy to construct and can be easily transported.
The disadvantages of these pipes is that they cannot withstand external load, if partial vacuum is created by emptying pipe rapidly, the pipe may be collapsed or distorted. These pipes are much affected by corrosion and are costly to maintain The life of these pipes is 25 to 50 years, which is much shorter as compared to cast Iron Pipes Steel pipes are not used in distribution system, owing to the difficulty in making connections.
• The joints in steel pipes may be made of welding or riveting, longitudinal lap joints are made In riveted steel pipes up to 120 cm dia.
