#Yes, you can use water for hydrotest.
#Hydro - means having to do with water.
#What is a hydrostatic or hydrotest? A hydrotest of a pipeline occurs when petroleum products that normally flow through the pipe are removed, and replaced with water. The water is then pumped up to a higher pressure level than is normally used when transporting petroleum, and held at that higher pressure for a period of time, generally eight to ten hours.
#Why are hydrotests conducted?
Quite simply to confirm the continued safe operation of the pipeline, ensuring that it's free of any defects. MPL conducts hydrotests as part of its comprehensive pipeline integrity management program.
#Why is water used during the tests?
Because hydrotests are conducted at a higher pressure level than a pipeline's normal operating pressure, if a leak or rupture occurs, it will occur with water in the pipeline, as opposed to petroleum products.

Yes water is used for hydrotest. You can test valves and other elements with water not only pipes.

Yes it is. As is air. However, air being compressible can create a hazard if a joint fails ... you can have pipe whipping around or launching. So water is preferred.

Yes. Hydro means water.

Mostly. It is cheap and fairly uncompressible.
It can actually be any fluid.
Hydraulic fluid is used in ultra high pressure assembly testing.
