Determine the high-pressure hose, and bend it with the output to experience it; look at the appearance, the high-pressure hose made of good raw materials is bright in color, and it is not easy to blacken. The very simple method is to use a magnet to absorb it, because the difference in composition between the two, The former is not necessarily resistant to chemical corrosion, while the latter is generally stainless steel.
The corrosion resistance of the high-pressure rubber hose depends on the aluminum elements contained in the steel. Basically, the aluminum elements also include nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to fully consider the stainless steel plate in various applications. According to the requirements of the mechanism and characteristics, the stainless steel wires on the steel welded mesh cover are neatly arranged, and it is not easy to fry the wires. This is also the inspection of the high-pressure hose production equipment.
Installation method of high pressure hose
High-pressure hoses are widely used in the field of petrochemical equipment, but there are also some difficulties in use. The key is the selection of the length of the high-pressure hose and improper installation methods. If the length of the high-pressure hose is too long, it will cause system instability. , improve liquid friction, increase industrial equipment damage and vibration and other difficulties;
If the length of the high-pressure hose is too short, it will not be able to achieve the purpose of compensation, shock absorption and noise reduction. Therefore, determining the length is the key work. In addition, the following factors must be fully considered: the characteristics of the chemical substance, the temperature of the operation process, and the operation process. The pressure, the diameter of the connecting pipe, the site category, the interface standard and the offset method, etc.
Proper installation of high-pressure rubber hose is the key factor to ensure full use of its characteristics. It is generally installed after the valve at the root of the pipeline, and there is also a valve behind the high-pressure hose to promote the formation of a conductive soft connection in the middle of the storage tank and the pipeline. The purpose of meaning is to facilitate maintenance and disassembly.
The high-pressure hose has a limited ability to compensate for the offset of the journal under natural conditions. When the installation length is equal to the natural length, it must not be able to bear the strong journal tension and cause cracks, which will lead to pipeline leakage. Therefore, the installation of high-pressure hoses The length should be smaller than the natural length to ensure a certain degree of playability.
Due to the horizontal and journal deflection produced by the high-pressure rubber hose digestion system, in addition to ensuring its playability during installation, it can also be digested according to the pattern of the pipeline. There are two broad ways of threading pipes: L-type and Z-type, and L-type installation wider,
The overall layout environment is neat and unique, reducing the length of the pipeline and reducing the liquid friction, but the journal stress field generated by the pipeline will act on the high-pressure hose and the storage tank, which reduces the service life of the high-pressure hose and the stop valve. Will be damaged, resulting in wholesale leakage of refined oil
