Abstract

Using a high-rise building water piping after hydrostatic test of the reliability of the leak to be completed ifthe pressure is maintained until the leak is not commercially available considered. Due to the nature ofhigh-rise buildings and the construction period will take several years from the lower levels of use of thewater supply and fire fighting water pipe construction is in progress, the order of which I do most of the firstpipe to the construction and more than three years. So kind of riser pipe is complete, install the valve in thebasement by installing an automatic pump to maintain a constant pressure after hydrostatic test and after eachfloor plumbing piping is complete, the progress of the hydrostatic test without undergoing a separate branchpipe the valve is opened automatically when the number of the pressing pressure of the structure. I kind of doand keep working pressure of pipe until the completion of the construction work to keep the damage to humanerror when it is intended to prepare. In winter, the frost protection and an alternative to drainage water pipe isdamaged or deformed, even if unaware of the finishing work to the building, the use of the damage caused bya leak in a after construction of finish work to be expected. Alternative to reduce this damage if the pressuretest without fear of freezing to help maintain long-term commercial pressures may be considered.Keyworld : Hydrostatic test, Pneumatic test, Temperature compensation of pressure
