Features of food grade PU material suction hose
Wear resistant hose is a common type of hose in construction. Because of the characteristics of the medium it transmits and the special reasons of the medium, the hose wears very much. It usually transports concrete, mud and other media with positive and negative pressure. Under special working conditions, the medium may contain corrosive substances, such as acidic and alkaline components. This requires that the rubber inside the pipe body must not only have the characteristics of wear resistance and pressure resistance, but also have certain corrosion resistance under certain conditions.
Safety of wear-resistant hoses
If there are certain requirements for safety and working pressure, it is generally used for type B. Its working pressure is about 5MPa~7MPa. It is usually used in occasions with certain requirements for safety. Because it takes into account both cost and safety, its cost performance is relatively moderate. The inner and outer rubber of the abrasion resistant hose are made of synthetic rubber. Therefore, wear resistance is guaranteed to a certain extent. Since the reinforcement layer will also use steel wire, its maximum bursting pressure is also improved to a certain extent.
Life of wear resistant hoses
The life of wear resistant hoses is usually measured by the volume passed. Cubic meters are generally used as the unit of measurement. Generally, the inner rubber layer of pipes used in construction will be worn after 2-3 months of use. The replacement requirements are different under different working conditions. The parts that are most prone to wear are usually the joints and the pipe body. The second most prone to wear is the part that is most prone to bending during operation. The bending part is under the greatest pressure during operation, so this part is also the most prone to wear.
