With regard to the hoses, the process can be divided into one-step PVC lay flat hoses and half-step lay flat hose. At present, some countries are still using half-step PVC lay flat hoses, and the half-step PVC lay flat hoses manufacturing process produces products of poor quality and time-consuming and labor-intensive. For some reasons, they also use this old process, and one-step method. The hose process is completed in one step without the need for other operations, and the manufactured flat hose is high in quality and easy to operate.
According to the field can be divided into industrial water hose, agricultural water hose, fire protection PVC flat water hoses, mining PVC lay flat hoses. Industrial grade PVC lay flat hoses require high working pressure, corrosion resistance and high temperature resistance are the main features of industrial grade PVC water hose. Agricultural water hoses do not require high working pressure and burst pressure, because the wear resistance is good in the field.
Fire-fighting pvc water hose is the most demanding, because in the process of re-fighting, if the fire fighting PVC lay flat hoses will cause bad consequences once the problem arises, the maintenance of the fire hose is also extremely high. The fire protection PVC lay flat hoses must be hung after use. Let dry in a cool, dry place. Mining grade PVC lay flat hoses are mostly used in mining – flexibility – wear resistance – corrosion resistant – high temperature PVC lay flat hoses, laying in the mining PVC lay flat hoses is too much trouble so in the process of using PVC lay flat hoses The pressure standard itself, so that the life of water hoses will be very long.
