Compound pipeline complex pipeline 300 convey material when, although material and the directly contact of pipe matrix 310,
But with the compound pipeline complex pipeline of pipe intrinsic silicon pasted with ceramic veneer block in the prior art when ceramic block comes off
It is different.In the compound pipeline complex pipeline of prior art, because ceramic block can be in compound pipeline complex pipeline when coming off
Pit is internally formed, causes the flowing of internal flow to be had greatly changed in pit, recessed
Easily generator tube matrix abrasion at hole, pit turns into the weakest link of compound pipeline complex pipeline.And the 3rd
The compound pipeline complex pipeline 300 of embodiment exists without pit, and the flowing of internal flow will not occur larger
Change, is constantly in the state of smooth flow, so the pipe body portion between wear-resistant block, though
So can also be washed away by fluid, but will not be occurred most as compound pipeline complex pipeline of the prior art
Weak link.Additionally, in the compound pipeline complex pipeline 300 of 3rd embodiment preferably by wear-resistant block it
Between distance be set smaller than the size of the particulate matter carried in material to be conveyed, such particulate matter
Pipe matrix that will not be individually between wear-resistant block is rubbed, and particulate matter is transported inside compound pipeline complex pipeline
When dynamic, certain part of particulate matter is necessarily contacted with wear-resistant block, and such wear-resistant block just can be preferably
Wear-resisting effect is played, the pipe matrix between wear-resistant block then can preferably play shock proof effect.
In order to further increase the case hardness and service life of composite pipe body 300, can also be right
The composite pipe body 300 after abrasion-proof structure 320 is formd on pipe matrix 310 to be heat-treated.
Under impact strongly, the wear-resisting tube layer of first embodiment and second embodiment has
Delamination is likely to occur, and the abrasion-proof structure of the wear-resistant block form of 3rd embodiment can be effective
Avoid delamination.The composite pipe body 300 of 3rd embodiment is applied to what thump wore and tore by force
Working condition.
