Abstract
The invention discloses a novel ultra-thick composite pipe with a corundum layer. The novel ultra-thick composite pipe comprises a pipe body, connectors and the corundum layer. The connectors are mounted at the two ends of the pipe body. A groove is formed in the left side of the pipe body, and an inserting head is mounted on the right side of the pipe body. The pipe body is formed by an anti-corrosion layer, a steel layer, a transition layer, a heat-resisting hexsteel, a fireproof layer, an aluminum oxide ceramic layer and the corundum layer. The aluminum oxide ceramic layer is arranged on the outer side of the corundum layer. The fireproof layer is arranged on the outer side of the aluminum oxide ceramic layer. The heat-resisting hexsteel is arranged on the outer side of the fireproof layer. The transition layer is arranged on the outer side of the heat-resisting hexsteel. The steel layer is arranged on the outer side of the transition layer. The anti-corrosion layer is arranged on the outer side of the steel layer. The novel ultra-thick composite pipe has excellent mechanical and heat shock resistance by arranging the corundum layer and the steel layer; by means of a reinforcing device, connector bodies and the steel pipe body of the novel ultra-thick composite pipe are firmer; and by means of the connectors, connection of the novel ultra-thick composite pipe is convenient and close.
Description
Technical field
The present invention relates to corundum layer multiple tube technical field, a kind of novel super thick corundum layer 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, and existing corundum multiple tube thickness does not reaches current requirement.
Summary of the invention
It is an object of the invention to provide a kind of novel super thick corundum layer multiple tube, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of novel super thick corundum layer multiple tube, including pipe main body, union joint and corundum layer, described pipe main body two ends are provided with union joint, it is provided with groove on the left of described pipe main body, and plug is installed on the right side of pipe main body, described pipe main body is by corrosion-resistant coating, steel layer, transition zone, heat-resisting hexsteel, flame retardant coating, aluminum oxide ceramic layer and corundum layer composition, and outside corundum layer, it is provided with aluminum oxide ceramic layer, it is provided with flame retardant coating outside aluminum oxide ceramic layer, heat-resisting hexsteel it is provided with outside flame retardant coating, it is provided with transition zone outside heat-resisting hexsteel, steel layer it is provided with outside transition zone, corrosion-resistant coating it is provided with outside steel layer.
Preferably, being provided with support means between described union joint and pipe main body, and support means is provided with eight altogether, support means is triangular support block.
Preferably, described union joint is provided with on installing hole, and each union joint and is provided with 16 altogether.
Preferably, the thickness of described plug is slightly less than the thickness of groove.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is by arranging aluminum oxide ceramic layer, make its wearability more preferable than conventional composite pipe, by arranging flame retardant coating, make its heat resistance more preferable, pass through corrosion-resistant coating, make its corrosion resistance higher, and by arranging corundum layer and steel layer, make resistance to mechanical and the thermal shock resistance properties with excellence, by arranging bracing means, make between its union joint body and steel pipe main body more firm, and by arranging union joint, make it easy to connect, and by arranging plug and groove, it is made to connect tightr, and compare with traditional multiple tube, its service life is longer.
