Description
Technical field
This utility model relates to corundum multiple tube technical field, is specially a kind of New Polycrystalline body corundum multiple tube.
Background technology
At present, Wear-resisting pipe fitting and traditional steel pipe, wear-resistant alloy cast steel pipe, glass-ceramic tubre and steel is moulded, steel rubber pipe etc. has internal to distinguish.Abrasion-proof pipe outer layer is seamless steel pipe, and internal layer is corundum.Corundum layer hardness is up to HV1100-1400, is equivalent to tungsten-cobalt hard alloy, and wearability is higher more than 20 times than carbon steel pipe.The corundum layer of the wear-resistant mainly a little millimeters thick of inner layer of abrasion-proof pipe, this both by composition and tissue, has had qualitative leap by thickness is wear-resistant than wear-resistant alloy cast steel pipe, glass-ceramic tubre again.Thus the adaptability aspect connecting the wearability of Wear-resisting pipe fitting, corrosion resistance, low temperature and high temperature is required more and more higher, and common multiple tube does not reaches this technology requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of New Polycrystalline body corundum multiple tube, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of New Polycrystalline body corundum multiple tube, including composite pipe body, union joint, ceramic layer and polycrystal corundum layer, described composite pipe body two ends are provided with union joint, it is provided with through hole on described union joint, described composite pipe body is by wearing layer, corrosion-resistant coating, steel layer, transition zone, ceramic layer, high-temperature-resistant layer and polycrystal corundum layer, and it is provided with high-temperature-resistant layer outside polycrystal corundum layer, ceramic layer it is provided with outside high-temperature-resistant layer, transition zone it is provided with outside ceramic layer, steel layer it is provided with outside transition zone, it is provided with corrosion-resistant coating outside steel layer, wearing layer it is provided with outside corrosion-resistant coating.
Preferably, described composite pipe body one end is provided with groove, and the multiple tube other end is provided with projection, described groove is provided with female thread, described projection is provided with external screw thread.
Preferably, described through hole is provided with eight altogether, and through hole is evenly distributed on union joint.
Preferably, described projection diameter is slightly less than groove diameter.
Preferably, the thickness of described wearing layer is 18mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model is by arranging wearing layer, make its wearability more preferable than conventional composite pipe, by arranging high-temperature-resistant layer, make its heat resistance more preferable, pass through etch resistant layer, make its corrosion resistance higher, and by arranging polycrystal corundum layer and steel layer, make resistance to mechanical and the thermal shock resistance properties with excellence, and by arranging union joint, make it easy to connect, and by arranging projection and groove so that it is connect tightr, and compare with traditional multiple tube, its service life is longer.
