4.75mm～5.25mm, hardness HRC is 30～40.
Described inner tube is wearing layer, and material uses 45Mn2, and outside dimension exists at 148mm～150.8mm, wall thickness
4.75mm～5.25mm, hardness HRC is 40～50.
Described outer tube and inner tube by hydraulic press be closely set with compound, press-fit and combine.
2 described mounting flanges use inside and outside 2 road girth joints to be set with and are fixedly welded on end, outer tube two ends.
2 described seams are separately positioned on the outer flange face of end, two ends mounting flange and protrude outer tube and inner tube suit
At end surfaces 2mm after Fu He, expand with heat and contract with cold because of Summer and winter or outer tube and inner tube during heat treatment is flexible poor for adjusting.
Described closure gasket groove is arranged on the outer flange face of left end mounting flange, and when being used for connecting, mounting O-shaped seals
Circle.
2 described loose flanges are set with and are arranged on outer tube two ends, the inner side of 2 mounting flanges.
8 described bolts hole are that circumferential 8 deciles are arranged at loose flange radial outer end, install and connect when being used for connecting
Bolt.
Described O RunddichtringO is arranged in closure gasket groove, 8 described M24 connecting bolts, circular washer, spring washers
By loose flange, this utility model is linked together with another basic utility model.
Compared with prior art, the beneficial effects of the utility model are: in a kind of construction disclosed in this utility model
Concrete pumping composite conveying pipe, structure uses outer tube to be set with inner tube structure form design, and its conveyance conduit is intrinsic pressure
Power maximum can reach 50MPa, can meet wearability and the requirement of antiknock ability of supertension concrete pump, additionally inner tube abrasion
After, by hydraulic press, the inner tube after abrasion can be extruded, the more compound inner tube of suit again, after pipe end seam turnery processing
Reuse so that this utility model can be reused, and saves resource, reduce manufacture purchase cost, solve existing skill
Deficiency present in art, can be widely applied to various use in construction.
