Structure: the main by liquid resistant synthetic rubber layer, layer, I, II, III layer steel wire braiding layer, weather resistant synthetic rubber adhesive composition. But according to the design principle of high pressure hose, III layer woven hose in hose pressure does not play any role, waste materials, increase the self weight of the hose, lower hose flexure. So, national standards were not the hose standard. Some enterprises of the old engineer continues to use the old standard, so in the design still people choose this type.

Application de tuyau à haute pression: industrie du charbon de tuyau à haute pression, industrie pétrolière de tuyau à haute pression \ n Industrie de charbon de tuyau de haute pression \ n L'industrie de charbon avec le tuyau hydraulique principal de tuyauterie. Au cours des dernières années, certaines exigences de pression de support hydraulique de mine de charbon a augmenté, une partie du tuyau tissé de fil d'acier ne peut pas répondre aux exigences de performance, les exigences d'utiliser un tuyau d'enroulement de fil. En outre, afin d'éviter la pollution de la poussière de charbon dans le processus d'extraction du charbon et améliorer la sécurité de production et augmenter les variétés d'huile de charbon, tels que l'exploration du charbon dispositif de trou de tube télescopique pour mine souterraine injection, opération de jointoiement. Selon les rapports, les fabricants nationaux ont la production et par plus d'une douzaine d'essais de charbon, d'autres produits importés similaires. \ N \ n Tuyau haute pression industrie pétrolière \ n \ n La stratégie de développement pétrolier offshore du 21ème siècle en Chine se concentre sur le développement et pétrolier offshore. Par conséquent, l'industrie pétrolière, en plus de l'utilisation de tuyaux de forage, des tuyaux vibrants, également appelé l'utilisation de tubes d'huile de mer peu profonde. L'oléoduc sous-marin a été la production nationale, mais les tubes à huile flottants ou semi-flottants et les tuyaux d'huile de mer profonde dépendent encore des importations. Avec la mise en œuvre de la stratégie de développement pétrolier offshore de la Chine, l'extraction pétrolière offshore sur les exigences de performance des tubes continuera à améliorer.

\ n \ n \ n Cause de l'endommagement du tuyau haute pression \ n \ n La qualité de fabrication du tuyau haute pression est mauvaise

(1) high pressure hose pipe wall of the inner layer and the outer layer is oil resistant rubber, middle (2 ~ 4) cross woven wire or wire winding. The poor quality of the hose will appear: tube wall thickness, steel wire braided tight, too loose or steel wire layer is too small; pressure hose after deformation (elongation, shortening or bending deformation) larger; the outer rubber seal difference lead to corrosion of steel wires; inner rubber seal is poor the high-pressure oil easily into the wire layer; layer and the steel wire layer adhesion problems. Above will enable hose to bear force is reduced, eventually in the tube wall is weak at appears to burst.

(2) hose and joint assembly of withholding the amount and withhold speed selection improper, or joint structure and material, the size of the selection is not reasonable, can lead to hose and joint pressure too tight or too loose, causing the early damage of the joints. Damage accumulated directly into the pressure hose used hydraulic hose assembly, if the withholding amount is too small, i.e., joint and pressure too loose in the role of a hose in early May from the joint in prolapse; if the withholding amount is too large, joint and too tight, easily lead to hose inner layer by the local damage, cracks, high pressure oil from the ruptured wire layer, and then along the wire between the gap and fled to the coat tail jet, or has been along the wire layer channeling to somewhere, so that the outer rubber drum kits and even rupture. Hose and connector in the assembly, if the withholding rate is too fast, easy to cause the inner rubber and steel wire layer fracture and the hose in the use of premature damage.

(3) in addition, joint design is unreasonable, the processing quality is poor, resulting in gum damage; if the joint material selection improper, in withholding is easy to deform, thus affecting the quality of crimping, hose life relationship.
