Common fault analysis of each layer of steel wire braided hose

With the rapid development of science and technology, the quality requirements of steel wire braided hoses are getting higher and higher, which belong to hydraulic hoses. For those who use hydraulic hoses for the first time, the environment in which the hydraulic hoses are used will directly affect their use. Hydraulic hoses are generally used in the industrial industry and are very common, so basically the demand is also large.
However, if people do not pay attention to the use environment and use it in a strong acid and alkali environment, the hydraulic hose will naturally be corroded. Or used in some high temperature places, the steel wire braided hose may be melted. Common causes of hydraulic hose failure:
1. Failure of the inner rubber layer
Significant swelling of the tube may be due to the material of the tube being corroded by the passing medium, or the temperature exceeding the specified temperature. Therefore, when replacing the hose, it is very important to know whether the hose is compounded with the passing medium and whether it can withstand the working temperature. If not, you need to change to a better quality steel wire braided hose.
Second, the outer rubber layer failure
When the outer rubber layer is found to be cracked, first observe whether the inner rubber layer has any problems. If there is no problem with the inner rubber layer, it may be that the outer rubber layer has been cut by a sharp object, or has been cracked by severe cold. Therefore, do not move the hose in a cold outdoor environment. If there is a bulge in the cover, first check whether it is a quality problem or improper use. See Tube Layer Failures.
3. Enhancement layer failure
The reinforcement layer is mainly made of steel wire braided or wound, all of which are metal fabrics. If it is corroded, it is easy to rust, which will weaken its strength and cause it to rupture under high pressure. This condition is usually accompanied by cracking and abrasion of the cover. If the joint breaks, it may be because the joint is not tight enough to allow moisture to enter the reinforcement.
The above are the common reasons for the failure of each layer of the steel wire braided hose. During the application process, attention should be paid to the abnormality of the hose to ensure the safety during use.
Our company LT581 SAE 100R12 four-layer steel wire wound high pressure hydraulic oil pipe, heat-resistant oil synthetic rubber, 4-layer steel wire winding layer, the temperature range is -40°C~+121°C (-40°F~+250°F), with excellent hydraulic Fluid compatibility, this series of hoses perform high performance characteristics, and are perfectly presented in design, manufacturing and other processes and finished product testing. It is mainly suitable for the use of petroleum-based hydraulic oil and is suitable for harsh operating environments.
