Suddenly leaking pipe joints how to do

In the hydraulic system , both the metal pipe fitting , or hose fittings , there are prone to leakage problems . For ferrule fittings, mostly due to pipeline subject to greater external force or impact, so that the card sleeve loose or deformed face caused by hydraulic adapters , you should check whether the card holder out of round , whether the defect edge , whether the pipe ends intact and nut, compression level , etc., while also eliminating hydraulic hose assemblys force. For flared fittings, mostly due to excessive flaring , quality, undesirable or multiple demolition , resulting in flared cracks or deformation caused by leaks , then you can be re- flared front truncated . If you use a male and female cone top pressure seal , the leakage is mostly due to two cone damage, available on the cone abrasive grit grinding .
    In some with "о" or outer -ring face seal by the occasion , the leakage following reasons : "о" ring aging or deformation caused by leakage ; "о" ring assembly is not in place , so that the two plane connection when pressure is uneven or "о" ring being cut cause leakage ; "о" rings uncompacted , elastic deformation caused by insufficient leakage ; "о" spigot ring groove too deep and cause leaks. In this regard , the need to re-select the same diameter and cross-sectional thick "о" rings can also be sealed with a rabbet plane for cutting grooves or grinding to reduce the rabbet groove depth , so that "о" rings are flexible enough to deformation ( compression should generally be between 0.35-0.65mm ) .
