Abstract
The utility model relates to a metal pipe with three layer corrosion preventing, hole sealing, scaling preventing, and wax deposition preventing coating. One layer of corrosion preventing layer is electroplated on the inner wall 1 of a metal pipe, one layer of intermediate hole sealing layer 4 is electroplated on a corrosion preventing layer 3, and one layer of scaling preventing and wax deposition preventing layer 2 is electroplated on the intermediate hole sealing layer 4. The thickness of the corrosion preventing layer 3 is 1.0 mu m to 100 mu m, the thickness of the intermediate hole sealing layer 4 is 0.8 mu m to 20 mu m, and the thickness of the scaling preventing and wax deposition preventing layer 2 is 205 mu m. The corrosion preventing performance of the utility model can reach more than 10 grade, the scale preventing rate of a water pipe can reach more than 90 %, and the wax deposition rate of an oil pipe can reach more than 50 %. The utility model can realize long-time work at the temperature of 40 DEG C below zero to 280 DEG C without layer separation and ageing. The utility model can be used in the technical field of oil transportation, water delivery, containers, etc.
Description
The utility model belongs to the improvement of inner wall of metal tube coating structure.
The existing inner wall of metal tube that is used for oil transportation or water delivery generally only is coated with anticorrosive coat, and there is not the coating of sealing of hole layer and good antiscale property and anti-wax deposition, such metal tube just is difficult to oil transportation and aqueduct, because of containing higher wax composition in the crude oil, wax is often tied and is resulted in blockage on inner tube wall in the oil transportation process.Also, in water delivery, easily cause the fouling of inner tube wall by containing compositions such as insoluble salt in the water.
The purpose of this utility model is a kind of a kind of metal tube with anticorrosion, sealing of hole, good antiscale property and three layers of coating of anti-wax deposition of development, the inwall of this metal tube not only has anticorrosive coat, also have good antiscale property and anti-wax deposition layer, and the mesosphere with sealing of hole effect, make this pipe can be used for oil transportation and water delivery.
The utility model plates intrinsic one deck anticorrosive coat 3 on inner wall of metal tube 1, on anticorrosive coat 3, plate the middle sealing of hole layer 4 of intrinsic one deck again, on middle sealing of hole layer 4, plate intrinsic good antiscale property and anti-wax deposition layer 2 again, the thickness of anticorrosive coat 3 is 1.0-100 μ m, the thickness of middle sealing of hole layer 4 is 0.8-20 μ m, and the thickness with anti-wax deposition layer 2 after the anti-caking is 2-50 μ m.
The utlity model has the performance of anticorrosion significantly, antiscale, anti-wax deposition, anticorrosion reaching more than 10 grades, the water pipe antiscaling rate reaches more than 90%, and the anti-paraffin depositing ratio of oil pipe reaches more than 50%, anticorrosive coat and matrix bond are firm, but long-term work and not delamination, aging under-40-280 ℃ environment.It can be used for fields such as oil transportation, water delivery, container.A large amount of troubles that scale removal, paraffin removal bring and the problem that cost of production is heightened have been avoided.
Fig. 1 is the utility model overall structure schematic representation, and Fig. 2 is its plan view.
Example executes one: present embodiment is selected low many steel pipes 1 that close for use, the anticorrosion bottom 3 of the intrinsic high phosphorus alloy of plating on the inwall of steel pipe 1, the thickness of bottom 3 is 50 μ m, on bottom 3, plate the middle sealing of hole layer 4 of intrinsic low phosphorus alloy again, middle sealing of hole layer 4 is thick to be 5 μ m, on middle sealing of hole layer 4, also plate intrinsic in phosphorus alloy good antiscale property and anti-wax deposition layer 2, the thickness of good antiscale property and anti-wax deposition layer 2 is 15 μ m.
Claims (1)
1, a kind of metal tube that has anticorrosion, sealing of hole, good antiscale property and three layers of coating of anti-wax deposition, it is characterized in that going up plating intrinsic one deck anticorrosive coat (3) at inner wall of metal tube (1), on anticorrosive coat (3), plate the middle sealing of hole layer (4) of intrinsic one deck again, on middle sealing of hole layer (4), plate intrinsic one deck good antiscale property and anti-wax deposition layer (2) again; The thickness of anticorrosive coat (3) is 1.0-100 μ m, and middle sealing of hole layer (4) is thick to be 0.8-20 μ m, and good antiscale property and anti-wax deposition bed thickness are 2-50 μ m.
