Abstract
The utility model relates to a public security fire fighting pipe comprising a steel pipe, wherein the steel pipe is internally provided with an epoxy resin layer I and externally provided with an epoxy resin layer II. The utility model has the advantages that the epoxy resin layers are modified by epoxy resin and are not easy to corrode because of extremely strong corrosion resistance; the public security fire fighting pipe can supply water in time when fire disaster happens and is safe and reliable; the epoxy resin has superior high temperature resistance and is not easy to deform when external temperature is higher; the production process of the whole product is simple, practical, environmental-friendly and economical, and the product performance conforms to various national standards.
Description
Technical field
The utility model relates to a kind of water pipe, especially a kind of public security fire-fighting pipe.
Background technique
At present domestic tubing kind of carrying as fire water is a lot, but every kind all has very big defective separately.Very easily oxide etch of the welded steel pipe of Shi Yonging, cast iron tube and Coating Steel Pipe at first.In the spraying system of fire fighting that does not circulate, be easy to blocking pipe, cause when fire takes place, can not spraying water outlet timely and effectively, put out burning things which may cause a fire disaster, cause bigger loss throughout the year because internal incrustation gets rusty; The outside also gets rusty easily, befouling environment, and working life is lower.
Because its steel pipe easily gets rusty and produces dirt, cause steel pipe oxide etch and cause the steel pipe breakage to leak, water resource waste, the reduction of pipeline water pressure.And steel pipe is because oxide etch, the wall thickness attenuation, and the steel pipe bearing capacity reduces, and this just causes reprocesses frequently, and maintenance load is big, shortcomings such as maintenance cost height.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, provides a kind of anticorrosion resistance to heat good public security fire-fighting pipe.
The utility model solves the technological scheme that its technical problem adopts: this public security fire-fighting pipe, comprise steel pipe, and be provided with epoxy resin layer one in the steel pipe, steel pipe is provided with epoxy resin layer two outward.
As preferably, the epoxy resin layer outer layer thickness is preferably 300～450 microns, and the interior layer thickness of epoxy resin layer is preferably 300～400 microns, and the pipe performance of this thickness range is best.
The effect that model utility is useful is: one, epoxy coating is that its corrosion resistance is extremely strong by spraying behind the epoxy resin modification, be difficult for being corroded, and the compression resistance height, water outlet in time is safe and reliable when fire takes place; Two, the epoxy resin high temperature resistant property is superior, is difficult for deforming when external temperature is high, carbonization; Three, the production technology of entire product is simple and practical, and environmental protection and economy meets national every standard.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional drawing at A-A place among Fig. 1;
Description of reference numerals: steel pipe 1, epoxy resin layer 1, epoxy resin layer 23.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: a kind of public security fire-fighting pipe, its mesosphere are steel pipe 1, be epoxy resin layer 1 in the steel pipe 1, use special technology to make it evenly on the inwall attached to steel pipe, and the laggard curing oven curing of thickness that reaches expection makes its internal layer attached to steel pipe; By electrostatic spraying, be epoxy resin layer 23 outside the steel pipe 2, with the outer surface of epoxy powder attached to steel pipe, the laggard curing oven of thickness that reaches expection solidifies makes its skin attached to steel pipe.
The modified epoxy layer is except corrosion-resistant, and resistance to heat is also very superior, and heat-resisting peak value can reach 760 ℃, and after 1 hour, the tubing coating does not have carbonization phenomenon and bubble is outstanding, do not have coating embrittlement phenomenon under-30 ℃ of conditions in baking under 300 ℃ of conditions;
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
