Why PU hose is better for a suction machine
Tank truck hose is a flexible and oil resistant hose. It is on the tail of a tank truck to deliver various oils like fuel, diesel, etc. Tank truck hose can be made from different materials. Then next let me introduce you some types of such oil hose.
Metal Hose
Metal hose is the traditional material for tank truck delivery hoses. It is mainly made of stainless steel, carbon steel and other metals. Metal hoses have high strength and wear resistance. But it is heavier. Therefore, installation and maintenance are more complicated. In addition, metal hoses tend to harden at low temperatures, affecting transportation efficiency.
Synthetic rubber hose
Synthetic rubber hose is a new material that has gradually replaced metal hoses in recent years. It has the characteristics of light weight, wear resistance and anti-aging. And has good flexibility. However, in high temperature and high pressure environments, synthetic rubber hoses are prone to deformation and aging. So compared to metal hoses, the service life is relatively short.
Polyurethane hose
Polyurethane hose is a new type of tank truck delivery hose material that has developed rapidly in recent years. It has the advantages of high strength, wear resistance, anti-aging, and light weight. And has a longer service life. However, polyurethane hoses are more elastic. Therefore, it is easily affected by external impact, resulting in damage.
Compound hose
Composite hose is a new type of tank truck conveying hose that combines multiple materials. It combines the advantages of various materials, such as strength, wear resistance, lightness, etc. And has a longer service life. However, composite hoses are more expensive to manufacture. Therefore it is difficult to apply on a large scale.
It should be noted that hoses made of different materials have different characteristics, uses and scope of application. Therefore, when selecting the material of the tank truck delivery hose, actual needs and working conditions should be considered. This ensures that the hose can complete the conveying task safely and effectively. At the same time, pay attention to following relevant safety regulations and standards.
