Pipe Patcher

Lile ductile iron repairer improves the mechanical properties of the shell on the basis of the existing repairer, and the novel sealing structure improves the compression resistance and sealing performance. The surface is sprayed with epoxy resin powder, which improves the corrosion resistance of the repairer. Extended service life.

Classification and code regulations according to applicable pipeline types

(1) Plastic pipe socket mender

Model representation method: it is composed of pipe type code and pipe nominal size.

For example, P110 represents a socket repair device for plastic pipe with an outer diameter of 110.

(2) Plastic pipe straight plug repair device

Model representation method: it is composed of pipe type code, pipe nominal size and patcher length.

For example, p200x300 refers to the in-line patcher for plastic pipes with a diameter of 200, and the length of the patcher is 300mm.

(3) PE, PVC plastic pipe reducing connection repair device

Model representation method: it is composed of pipe type code, nominal size of main pipe / Engineering size of branch pipe. For example, P110 / 63 represents the repair device for plastic pipes with an outer diameter of 110 for the main pipe and 63 for the branch pipe.

(4) PE, PVC plastic pipe tee connection repair device

Model representation method: it is composed of pipe type code, nominal size of main pipe - nominal size of branch pipe and s.

For example, P110 / 110s refers to the plastic pipe equal diameter universal repair device with the outer diameter of main pipe 110 and the outer diameter of branch pipe 110.

For example, P200 / 160S refers to the three universal repairers for plastic pipe reducing with the outer diameter of the main pipe of 200 and the outer diameter of the branch pipe of 160.

(5) Ductile iron pipe socket mender

Model representation method: it is composed of pipe type code and pipe nominal size.

For example, H50 refers to socket repair device for cast iron pipe with nominal diameter of 50mm.

(6) Ductile iron pipe in-line repair device

Model representation method: it is composed of pipe type code, pipe nominal size and patcher length.

For example, h200x300 refers to the in-line patcher for ductile iron pipes with a diameter of 200, and the length of the patcher is 300mm.

It is widely used in the rapid repair of pipes of various materials in petroleum, chemical, light industry, medicine, food, construction, municipal and other industries.
