Valve kp-lok.com is an amazing component used in flow control system, but it could become problematic if not isolated. To do a marvelous plumbing job, creativity is required, and so it is in every piping system construction. Shortcuts in workmanship can be tempting, but in the end, it pays to do the right thing than looking for a quick fix as it will cost more in the end. When dealing with valves in plumbing jobs, there are red flag matters to watch out for if achieving top quality job is desired. A plumber knows that his piping construction will one day need maintenance, and thus would plan control valve isolation at the planning stage to make future maintenance work easier. Not factoring proper valve isolation in the design and implementation flow control system is a red flag every valve engineer must guide against.
In planning plumbing work design, it is important to guide against possible red flags by considering the proper place to location valve isolation so that when the piping system is being maintained due to scheduled maintenance or emergency repair, the entire system will not have to shut down or be in trouble pending resolution of an impending problem.
Control valve isolation
Not isolating control valve or the isolation is done shoddily means red flag that due care is required to plan it. As the pipeline is being planned, there is need to consider areas along the pipeline route, the appropriate places to plan isolation. Valves like butterfly, ball, check, and globe have their relevance in a plumbing system. Unless the right valve is used at the right place, wrong use of valve during flow system construction may lead to a future problem that can rubbish the entire work.
Chambers where control valve has no way of isolation
Valuable real estate space is consumed by valve chambers and control valve. However, you need to make provision for enough space for personnel to work during maintenance. You can use butterfly valve where it impossible to install gate or any other valve. Remember that the maintenance personnel and even the pipeline operator may need access to such place in the future. Therefore, create enough space where the isolation valve is located.
Installations with no pressure gauges or provisions to temporarily install one
Some utilities do have calibrated test gauges that move from site to site; such facilities are facilities offer their connections to access their sites. However, the concern is those pipeline facilities that lack such fittings. A good practice when installing a valve is to make provision for anyone setting the valve to see the actual pressure right at the valve. Such practice allows for effective setting when the person who is to set the valve can see what they are setting. The use of telemetry capabilities and supervisory control and data acquisition (SCADA) provides for anyone at the site to see what the pressure is running through a valve, with that you know what you want to face before you even start to work.
Valve chambers with no piping allowances for the removal of the main components. Ideally, piping installers do not bolt everything is a concrete chamber without provision for some coupling for easy maintenance in the future. A piping construction where the components are tightly bolted without a plan for maintenance will hinder repair works in the future. Therefore, valve construction must provide for maintenance of the system at some points in the future, not doing this right from the point of design and installation of a piping system is a red flag that must be avoided.
