What cause concrete hose blocked
Bundling Method
The bundling method works for emergency repairs of rubber hose ruptures—just make sure the pressure stays below 16MPa. Here’s how to do it: Apply oxygen resin glue to the ruptured area of the soft rubber hose. Next, wrap 2–3 layers of oil-resistant rubber over the rupture. Use rubber strips that are 2–3 times longer than the rupture itself, and coat each layer with glue. Finally, tie the wrapped rubber tightly with No. 12 iron wire and let it solidify.
Bone Setting Method
This method helps when a nitrile rubber tube’s rupture is severe—either from external force or system overload, making it nearly broken. First, wipe the rupture clean and cut off the damaged section. Then insert a steel “bone” into the cut end of the hose. In urgent situations, you can use a steel pipe instead, as long as its outer diameter matches the hose’s bone diameter. After inserting the “bone,” clamp the hose and “bone” together with a homemade steel plate clamp. Remember to clean the repaired hose before using it again.
Restructuring Method
Hydraulic systems use flexible rubber pipes with different joints, so the bundling method isn’t ideal for high-pressure hoses. Instead, try restructuring: Remove the pipe joint from the ruptured hose. Find a replacement rubber pipe with similar pressure capacity and length. Saw off its pipe joint. Then weld the angle of the ruptured hose’s original joint onto the replacement hose.
These three methods can repair broken rubber pipes. Still, prevention is better: Choose high-quality hoses, focus on proper daily use, and maintain them regularly. This will reduce the chance of ruptures in the first place.
