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 ) . For the use of oil and rubber, wool felt, soft steel cardboard, combined sealing gasket or sealant hydraulic hoses joints , whether any material , you should first check the seals for damage , deformation, aging and rough through the large , etc. and then take the appropriate measures.

Card sets of pipe joints double fittings is how to install

Joint treatment: Make sure the connector inside the front and back ferrule is not missing , and is in the correct position.Do not appear like the following scenario : front , back ferrule, front ferrule direction of dislocation hold against the back ferrule direction lost hold against the back ferrule to prevent such situations is this: do not easily loosen or tighten the nut, next . Pipe handling : inserthydraulic adapter surface should be smooth part intact, avoid scratches and other defects. As shown in the bottom of the tube surface is scratched , the sealing joints affected . To end the tube axis perpendicular to the tube , the tube mouth without glitches. If you want to bend hose fitting , the pipe ends to set aside a certain length , see below L value , connector manufacturers to follow the advice given value , otherwise it will affect the pipe insertion and sealing. III. Note fittings matching size and pipe size . If OD3/8inch and OD 10mm hydraulic hoses , diameter close, but not with OD10mm OD3/8inch the tube connector , and vice versa is also true . Manufacturers usually in metric fittings made ​​a mark , the installation should pay attention to distinguish .

Flared fittings pre-installed

Pre-installed , you should try to keep the tube and the coaxial connector body , if the pipe deflection is too large will cause seal failure.
    Preloaded force should not be too large. Should make the inner edge ferrule tube wall just embedding , card sets there should be no significant deformation . During pipeline connection, then the provisions of the tightening force assembled . φ6-10mm ferrule tightening force of 64-115N, φ16mmr 259N, φ18mm for 450N. If the pre- deformed when the card holder will lose the seal.
2 , prohibits adding sealant filler. It was sealed in order to achieve better results, apply sealant put on the card , the results sealant being washed into the hydraulic system , causing the hydraulic components orifice blockage failures. 3, the connecting pipe should be sufficient deformation of the tube margin , to prevent the tube subjected to tensile stresses. 4, the connecting pipe should be avoided when it suffered lateral force , lateral force caused Mifengbuyan over the General Assembly . 5, the connecting pipe should be a good one tight , to avoid multiple disassemble , otherwise it will seal performance deteriorated.
