Abstract
The utility model relates to a water supply plastic-coated composite steel pipe which comprises a steel pipe. The water supply plastic-coated composite steel pipe is characterized by also comprising an internal epoxy resin coating layer, an external epoxy resin coating layer or a galvanized layer; the internal epoxy resin coating layer is uniformly sprayed and coated on the inner wall of the steel pipe; and the external epoxy resin layer or the galvanized layer is uniformly sprayed and coated on the outer surface of the steel pipe. The water supply plastic-coated composite steel pipe provided by the utility model is scientific and reasonable in structural design, has the advantages of high corrosion resistance, no scaling, long service life, capability of resisting impact and temperature variation, small conveying resistance, and capability of guaranteeing the quality of drinking water, and is a water supply plastic-coated composite steel pipe with high innovation.
Description
Technical field
The utility model relates to a kind of feedwater piping, particularly a kind of feedwater plastic coated composite steel pipe.
Background technique
Feedwater piping is the vitals that is used in the water engineering to user's water delivery and water distribution, and supply pipe material commonly used has cast iron tube, steel pipe and prestressed concrete pipe, small-bore available galvanized iron pipe and plastic tube.For metal tube, its long-term contact easily with potable water is corroded, and shortens its working life, and is blended into the quality that also can affect potable water in the potable water after anvil cinder comes off on the tube wall.At present, in order to prevent that metal tube is corroded, people adopt the way of coated lining slush on the inwall of metal tube, although the method has prolonged the working life of metal tube, but because the slush wall surface is coarse, increased the resistance of potable water when carrying, and coming off of silt also can affect the quality of water.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, the feedwater plastic coated composite steel pipe that provide a kind of and have that design science is reasonable, anticorrosive, long service life, transporting resistance are little, can ensure quality of drinking water.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of feedwater plastic coated composite steel pipe, comprise steel pipe, it is characterized in that: be coated with epoxy resin layer in also comprising, be coated with epoxy resin layer or zinc coat outward, in be coated with epoxy resin layer and uniformly spray on the inwall of described steel pipe, outside the outer surface of steel pipe has uniformly sprayed, be coated with epoxy resin layer or zinc coat.
Advantage of the present utility model and good effect are:
1. this feedwater plastic coated composite steel pipe, be designed to through the powder melts spraying technology at the inwall of steel pipe or the composite steel tube of outer wall spray epoxy (EP) powder by passing by the water supply steel tube of structure, function singleness, because the superior function of this powder self with and on steel pipe inner wall extremely strong adhesion, thereby make that this composite steel tube has that corrosion resistance is strong, non-scaling, long service life, can resist and impact and variation, the transporting resistance of temperature are little, the advantage that can ensure quality of drinking water.
2. this feedwater plastic coated composite steel pipe, by spray epoxy (EP) powder or zinc-plated powder on the outer wall of steel pipe, the problem of having avoided steel pipe to shorten its working life because of the corrosion of the humidity of external environment condition or microorganism is for the long-term use of this composite pipe provides double shield.
3. the utility model scientific structure design is reasonable, having that corrosion resistance is strong, non-scaling, long service life, can resist and impact and variation, the transporting resistance of temperature are little, can ensure the quality of drinking water advantage, is a kind of feedwater plastic coated composite steel pipe with higher innovation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-is coated with outward in epoxy resin layer, 2-steel pipe, the 3-and is coated with epoxy resin layer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of feedwater plastic coated composite steel pipe, comprise steel pipe 2, its innovation is: be coated with epoxy resin layer 3 and the outer epoxy resin layer 1 that is coated with in also comprising, in be coated with epoxy resin layer and uniformly spray on the inwall of described steel pipe, outside the outer surface of steel pipe has uniformly sprayed, be coated with epoxy resin layer or zinc coat.
This feedwater plastic coated composite steel pipe can be carried-40 ℃-60 ℃ fluid, and its production technology is:
1. the compound front pretreatment ⑴ of steel pipe removes steel pipe to weld muscle by body stretching machine and does smooth processing; ⑵ utilize sandblasting machine with the steel pipe inner wall sandblast, to increase steel pipe and the adhesion that is coated with interlayer, prolongs the durability of coating, and be beneficial to the levelling work of compound tense; ⑶ polish the outer surface of steel pipe by shot-blasting machine.
2. the compounding ⑴ of steel pipe need to heat by the steel pipe that pretreatment is good; Steel pipe inside and outside wall coating machine carry out steel pipe inwall spray, inhale be coated with epoxy powder and in the outer wall spray of steel pipe, inhale and be coated with epoxy powder or zinc-plated powder; ⑶ levelling, cooling.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: in the spirit and scope that do not break away from the utility model and claims, various replacements, variation and modification all are possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
