Custom Food&Industrial Grade Rubber Hose
Detail
1. Hose structure is usually divided into three categories as follows:
1.1 Rubber hose with reinforced layer structure
1.1.1 Fabric reinforced rubber hose
1.1.2 Metal reinforced structural rubber hose
1.1.3 According to the structure of reinforcement layer
1.1.3.1 Laminated rubber hose: rubber hose made of coated fabric (or rubber cloth) as skeleton layer material, can be fixed with steel wire outside.
Features: clip cloth pressure hose is mainly made of plain woven cloth (its warp and weft density and strength are basically the same), cut by 45°, splicing, and wrapped. It has the advantages of simple manufacturing process, strong adaptability to product specifications and layer range, and good stiffness of pipe body. But it's inefficient.
1.1.3.2 Braided rubber hose: the rubber hose made of various wires (fiber or metal wire) as the skeleton layer is called braided rubber hose.
Features: The braided layers of the braided hose are usually interwoven according to the balance Angle (54°44 '), so the hose of this structure
It has good bearing performance, good bending performance and high material utilization ratio compared with the laminated rubber hose.
1.1.3.3 Winding rubber hose: The rubber hose made of various wires (fiber or metal wire) as the skeleton layer is called winding rubber hose. Features: similar to braided hose, high pressure strength, impact resistance and good flexure performance. High production efficiency.
1.1.3.4 Knitting hose: the hose made of cotton thread or other fibers as the skeleton layer is called knitting hose.
Features: knitting thread is interwoven on the inner tube billet at a certain Angle with the shaft. The intersection is sparse and generally consists of a single layer structure
