High-pressure hoses are now widely used in hydraulic systems. Both the coal industry and the oil industry can see the hose. High pressure hose is the first safety issue during operation, so its quality must be guaranteed. Recently, users have asked us how to prevent the leakage of high-pressure hose fittings. Today, we will explain in detail how to prevent the leakage of high-pressure hose fittings, thereby improving the safety of operations.
For the card-type pipe joints, most of them are subjected to large external forces or impact forces, causing the looseness of the ferrule or the deformation of the pipe end surface to cause leakage. At this time, check whether the ferrule is out of round, whether there is a defect in the cutting edge, and whether the pipe end is defective. The integrity and the degree of clamping of the clamping nut, etc., while also eliminating the external force of the pipe. For flared pipe fittings, due to excessive flares, unsatisfactory quality or multiple dismantling, resulting in flaring deformation or cracks, etc., leakage can occur. At this time, the front end can be cut off and re-expanded. If the male and female cone top pressure is used for sealing, the leakage is mostly due to damage on the two taper surfaces, and the conical surface can be ground by using abrasive sand. In some cases where the “о” ring is sealed against the end face or outside diameter.
The main methods for effectively preventing the leakage of high-pressure hose fittings are these. We must strictly abide by the operating instructions. Only in this way can we operate safely and improve the efficiency of our engineering.
