Large diameter flange rubber hose, also called hose joint, is a product that connects different hoses. Rubber joints have the advantages of pressure resistance, corrosion resistance, wear resistance, oil resistance, etc., and are suitable for hose lines with serious corrosion media such as acid, alkali, salt, etc., such as petrochemical, chemical, metallurgy, pharmaceutical, paper making and other industries.

Large-diameter flange rubber hose is a rubber hose with multiple sealing surfaces composed of an inner rubber layer, a reinforcement layer, and an outer rubber layer. Its function is to withstand the pressure during work, absorb vibration and impact during work, and prevent corrosion and wear of the rubber tube by the medium during work.

Large-diameter flange rubber hoses can be divided into rubber hoses for coal mines, rubber hose flange connection bolt joints for mines, rubber hoses for underground mines, rubber hose flange connection bolt joints for underground mines, and special rubber hose for coal mines.

What are the structural characteristics of large diameter flange rubber hoses:

• The outer rubber layer has been strengthened to give it a certain strength. A set of rubber sealing rings are added to the inner and outer rubber layers to achieve effective sealing between the inner rubber layer and the outer rubber layer to avoid media leakage.
• The reinforced material rubber hose is connected by reducing hoses for reinforcement. It can withstand larger axial thrust when bearing working pressure, and at the same time, it can ensure that the conveyed medium is not lost.
• When the pressure of the conveying medium is greater than the working pressure, unsaturated polyester resin is used as supplementary glue in the inner rubber layer and reinforcement layer of the rubber hose to improve the tensile strength and wear resistance of the hose and prevent the hose from bursting when under pressure.
