Abstract
The utility model discloses a steel tube with a nano glass lining. The DYD steel tube with a nano glass lining comprises a steel tube (2); a nickel layer (3) is plated on the inner wall of the steel tube and then a nano glass tube (1) is arranged on the nickel layer (3); and a polyurethane heat preservation layer (4) and a polyethylene protecting layer (5) are sequentially coated on the outer wall of the steel tube (2). The inner wall of the steel tube is not easy to cause scale or wax deposition, which is good for transport; the steel tube has acid and alkali resistance and long service life; and the layers of the steel tube are firmly combined.
Description
Technical field:
The utility model relates to a kind of insulation and carries collector tubing, especially a kind of nano-glass lined steel pipe.
Background technique:
This pipeline is widely used in oil field, chemical industry, pharmaceutical industry; in particular for field polymers oil recovery, poly-oil recovery, water-drive oil recovery, electric pump well and the ground petroleum pipeline annotated of ternary; at present along with oilfield construction enters the middle and later periods; Cut of Oilfield improves constantly; the working environment of pipeline is abominable day by day simultaneously, to having higher requirement in the protection quality and the working life of pipeline.The easy fouling of existing inner-walls of duct, wax deposition are unfavorable for transportation, and it is short to be subject to acid and alkali corrosion working life, and layer with layer between combine insecure.
The model utility content:
In order to overcome the deficiency that exists in the background technique, the utility model provides a kind of nano-glass lined steel pipe, and this steel pipeline inwall is less scaling, wax deposition helps transportation, the acid resistant alkali long service life, and combine firm between layer and the layer.
The technical solution of the utility model is: this nano-glass lined steel pipe comprises steel pipe, and the steel pipe inwall is lined with the nano-glass pipe after being coated with nickel dam, and outer wall of steel pipe is coated with polyurethane insulation coating, polyethylene protective coating successively.
The utlity model has following beneficial effect: between the nano-glass pipe of the steel pipe of this pipeline and its liner nickel dam is arranged, nickel dam makes be connected between steel pipe and the nano-glass pipe more firm, pipe lining has the nano-glass pipe, water is 9 degree at the wrapping angle of glass surface, wrapping angle at steel surface is 58 degree, wrapping angle at stainless steel surfaces is 46 degree, wrapping angle at resin surface is 75 degree, wrapping angle at polyethylene surface is 94 degree, the more little then hydrophilic effect of wrapping angle is good more, the hydrophily that this shows glass is better than other material far away, can form the stable moisture film of one deck on its surface, prevent, weakened the deposition of crude oil, effectively reduced wax control at tube wall, prevent that inner-walls of duct from stopping up, and helps transportation.In addition the nano-glass pipe of this pipeline have acid-fast alkali-proof, hydrophilic, hate oil, under 40 degrees centigrade constant temperature, nano-glass is placed in the mud acid 48 hours, weightlessness is not higher than 950mg/cm
2, under 40 degrees centigrade constant temperature, nano-glass being placed in the solution of sodium hydroxide 48 hours, weightlessness is not higher than 2.2mg/cm
2Also be incubated the high characteristics of surface finishment, coarse tube wall can increase the turbulence level of liquid, reduces the stability of moisture film, makes crude oil contact and adhere on the tube wall with tube wall, and smooth surface can reduce long-pending wax, prevents line clogging; The mechanical property that has heat-resisting, antitorque, the bending resistance of iron and steel again.
Description of drawings:
Accompanying drawing 1 is a structure half sectional view of the present utility model.
1-nano-glass pipe among the figure, 2-steel pipe, 3-nickel dam, 4-polyurethane insulation coating, 5-polyethylene protective coating.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this nano-glass lined steel pipe comprises steel pipe 2, steel pipe 2 inwalls are lined with nano-glass pipe 1 after being coated with nickel dam 3, there is nickel dam 3 to make more firm that steel pipe 2 is connected with nano-glass pipe 1 between steel pipe 2 and the nano-glass pipe 1, except physical connection, also have chemistry to be connected between steel pipe 2 and the nano-glass pipe 1, in addition the nano-glass pipe 1 hydrophilic, hate oil, any surface finish not wax deposition and dirt, help transportation, the strong long service life of acid-fast alkali-proof anti-pressure anti-torsion ability, steel pipe 2 outer walls are coated with polyurethane insulation coating 4, polyethylene protective coating 5 successively.
Claims (1)
1, a kind of nano-glass lined steel pipe comprises steel pipe (2), it is characterized in that: steel pipe (2) inwall is lined with nano-glass pipe (1) after being coated with nickel dam (3), and steel pipe (2) outer wall is coated with polyurethane insulation coating (4), polyethylene protective coating (5) successively.
