Leakage of the high-pressure hose fittings


High pressure hose joint leakage following reasons: "о" ring deformation caused by aging or leakage; "о" ring assembly is not in place, so that when the two planes uneven pressure connection or "о" ring is cut causing leakage; " о "ring uncompressed, less elastic deformation caused by leakage;" о "Mouth-ring groove too deep and cause leaks. In this regard, the need to re-select the same diameter and cross-sectional coarse "о" rings, also
american hose fittings
You can seal the mouth with a groove on the plane were cut or grinding, in order to reduce the groove depth mouth only, so "о" ring has sufficient elastic deformation (compression should normally be between 0.35-0.65mm) . For the use of oil sheet, wool felt, soft steel board, combined sealing gasket or pipe joints leak sealant, No matter what the material, you should first check the seals without damage, deformation, aging and rough through the large, etc. and then take the appropriate measures.

High pressure hose fittings installation considerations


(1) hose in motion or stationary, can not excessive bending, it can not be bent in the roots, at least to start bending at 1.5 times its diameter;
(2) The 60 Cone seal hose fitting is moved to the extreme position not pull it too tight, it should be more relaxed;
(3) try to avoid the Multiseal metric hose fitting twisting deformation;
(4) hose as far as possible away from the heat radiating member, fashion necessary insulation boards;
(5) Avoid hose external damage, such as the use of the same term friction surface of the member;
(6) If the hose caused by excessive weight deformation, should support members.

Metal hose materials are generally divided into three categories:

A class of materials: that used in the production process, may have a direct, significant impact (such as key features of the product, performance may have a direct impact) on the production of quality raw materials.
Class B material: refers to use in the production process, the potential indirect impact of raw materials or more important to the product quality.
Class C materials: refers generally aid, the impact on product quality or slight raw materials.
Since the production of the main parts of the Interlock Hose Fittings is austenitic stainless steel, thus ensuring the hose excellent heat resistance and corrosion resistance, the hose very wide operating temperature range, is -196-600 degrees, the use of hoses by pipelines through the medium of corrosive select the appropriate grades, you can ensure that the corrosion resistance of the hose.
Hose Scope: the need for adequate flexible delivery tube, to prevent vibration premises piping, steam, gas, air, heavy oil, petrochemical, chemical-pharmaceutical etc. apply.
Metal hose has good flexibility, fatigue resistance, high pressure, high temperature resistance, corrosion resistance, and many other features, it is relative to other hoses (rubber, hydraulic hose cutting machine) of life would be much higher, so it but also has a higher overall economic efficiency. With the development of modern industry, the high temperature, high pressure of demand for corrugated metal hoses also getting bigger and bigger.
