Emergency Repair for Hydraulic Hoses

2023-11-23


During the construction process, when the hydraulic hose of the construction machinery breaks, the following emergency repair methods can be used.

1. Adhesive filling method

When a hydraulic hose in a hydraulic control system ruptures with a pressure between 25-8.0MPa, use the following method: clean the area around the rupture, apply anaerobic adhesive or epoxy resin, and apply either glue 801 or glue 502. Wrap 4-5 layers of tape or canvas strips around the area, forming a knot at each end of the canvas strip. Let dry for 15-20 minutes before use.

2. Bundle method

The bundling method is the appropriate solution for rubber hoses that require emergency repair and have a working pressure below 16MPa. In order to execute this method, you must apply adhesive to the damaged portion of the hose, wrap the bonding part with 2-3 layers of oil-resistant rubber, tightly bind the wrapped rubber with No. 12 iron wire, and allow it to solidify.
