high pressure Sandblasting pipe The abrasion resistance and compressive strength of the high pressure sand blasting pipe are very high, but in case of extreme conditions or some improper operations, the high-pressure sand blasting pipe may be broken. How to deal with this situation? It is too wasteful to replace a new sandblasting pipe directly. Are there any other remedial measures? below Sand blasting hose manufacturer Let's give a brief introduction:

1、 Binding method of high-pressure sand blasting pipe

The bundling method is applicable to emergency repair of broken rubber hoses with pressure below 16MPa. The specific method is: apply one of the common adhesives for construction machinery to the hose rupture; Wrap 2-3 layers of oil resistant rubber with a width 2-3 times the length of the broken part (each layer shall be coated with glue); Bind the wrapped oil resistant rubber with No. 12 iron wire until it solidifies.

2、 High pressure sand blasting tube osteosynthesis

When the rubber hose is broken or about to be broken due to the action of external force (fragment breakdown, extrusion fracture) or system overload, the bone bonding method can be adopted: wipe the broken part of the hose clean and cut the broken part; Insert the self-made steel "bone connection" into the cut off hose (in case of special emergency, the steel pipe with the same outer diameter as the hose bone diameter can also be used as the "bone connection"); Clamp the hose and "bone connection" with self-made steel plate clamp (in case of special emergency, No. 8 iron wire can be used to replace self-made steel plate clamp); Clean the connected hose before use.

3、 High pressure sand blasting pipe bonding method

When the rubber hose with the pressure of the hydraulic system between 25-8.0MPa breaks, the adhesive method can be adopted: wipe the area around the broken hose; Apply one of "anaerobic" glue, "epoxy resin" glue, "801" glue or "502" glue (the length of glue coating is about 2-3 times of the length of the broken part) on the broken part of the hose; Use adhesive tape or canvas strip to wind 4-5 layers of adhesive coating (each layer shall be coated with adhesive); Tie the ends of the wrapping tape and the canvas strip into a dead knot; It can be used after 15-20 minutes of solidification.

4、 High pressure Sandblasting pipe Reform law

As the pipe joints of each rubber hose in the hydraulic system are different, at the same time, the high-pressure or ultra-high pressure broken hose should not adopt the "bonding method", "binding method" or "bone bonding method". Therefore, the modification method can be adopted: saw off the pipe joints of the broken hose; Find a substitute hose with pressure bearing capacity and length similar to the broken hose, and saw off its pipe joint; Weld the angle of the coupling of the broken hose to the replacement hose; Clean the welded hose before use.
