Maintenance is generally throughout all kinds of industries an important topic. A famous example is the car industry: You have to get your car regularly to the garage for check-ups and maintenance if needed. The ball valve industry is no exception to this. Valves have to be maintained in order to keep it functioning. In times like these, maintenance is playing a more important role than perhaps before. Maintaining a valve, instead of replacing or re-designing, can sometimes be very cost effective for the end users.
Maintaining valves the right way; By Nwaoha Chikezie of CASEI
Valve maintenance is the best way of managing control valves, in order to control fluid flow. When making repairs on valve types, use the available manufacturer’s technical manuals. As soon as a leak is detected quickly determine the cause, and then apply the corrective maintenance. Maintenance may be as simple as tightening a packing nut or gland. A leaking flange joint may need only to have the bolts tightened or to have a new gasket inserted. Scale if allowed to collect, will cause leakage. Loose hangers permit sections of a line to sag, and the weight of the pipe and the fluid in these sagging sections may strain joints to the point of leakage.
