Precautions when purchasing and using steel wire hose

Polyurethane steel wire hose products are made of special TPU embedded spiral steel wire, which is wear-resistant (3-4 times better than rubber; 6-7 times soft PVC), anti-aging, tear-resistant, highly transparent, and can observe the suction and conveying process , Light weight, good elasticity, good resilience and low temperature compressibility and other properties, with ultra-high strength and ultra-long service life. The hose made of PUR material has the properties of stretch resistance, strong tension, high tear strength, abrasion resistance, flexure resistance, penetration resistance, low temperature resistance, hydrolysis resistance, etc., and has good resilience and service life. long. Flame-retardant requirements meet; UL94-HB standard, in line with ROHS regulations, grounding through spiral wire can discharge static electricity. It does not contain plasticizers, is non-toxic and tasteless, and is a high-performance environmentally friendly hose.

   First, determine the diameter of the hose. Wire hoses are generally connected by hose clamps, which is convenient and simple. Therefore, it is necessary to determine the size of the hose diameter before purchasing. Generally speaking, the diameter of a steel wire hose refers to the inner diameter of the hose or the outer diameter of the steel pipe.
   Second, determine the type of hose, plastic rib, steel wire or static electricity. According to the different materials to be transported, determine the type of hose required. The static conductive hose is mainly used to transport some substances that are prone to static electricity, and the plastic hose is used to transport or suck some wear-resistant dust or dry materials.
   Third, determine the wall thickness of the hose, based on pressure, etc. Generally speaking, the thicker the wall thickness of the hose, the worse the bendability and the better the wear resistance. Therefore, the selection will be determined according to the wear resistance and pressure resistance of the conveyed material.
   Fourth, under normal circumstances, it should be within the appropriate temperature and the indicated range. One of the main purposes of this is to better protect the hose. Because it is a chemically synthesized product, the requirements for the environment are relatively higher, especially to master the specific temperature conditions, it will be very important. Of course, in this process, the specific pressure situation and the corresponding temperature situation should be considered comprehensively. After the swelling situation occurs, it should be combined with the actual situation and corresponding analysis should be carried out. Eliminate related problems.
   Fifth, of course, in this process, it is also very important to consider the corresponding amplitude frequency. After the use is completed, it should be stored accordingly. When storing, it should be placed in a place with relatively good ventilation performance. The specific dimensions should also be measured to avoid the corresponding sunlight and light exposure. Therefore, at this time, it is relatively important to grasp the precautions for steel wire hoses.
Sixth, at the same time, you should also have an understanding of the assembly situation. In the process of assembly, you should choose the size of the hose. In the process of installation and matching, you should choose the shape of the hose. Properly deal with it. When the corresponding connector is installed in the hose, please reconfirm the stability of the corresponding interface. If the overall stability is strong, the corresponding effect will naturally be more obvious.
   Seventh, there should be regular inspections, and if abnormalities are found, they should be truthfully registered. In the process of using the polyurethane steel wire hose, the overall life span mainly depends on the physical and chemical properties of the carrier. At the same time, the specific temperature, the corresponding flow rate, and the specific pressure are also mastered and understood.
