Abstract
The utility model discloses a composite water and gas supply steel pipe for fire protection. the composite water and gas supply steel pipe comprises a steel pipe, wherein the inner side and the outer side of the steel pipe are respectively provided with a modified epoxy resin layer, the modified epoxy resin layer on the inner side of the steel pipe is coated on the inner side of a base pipe through an electrostatic spraying technique. According to the composite water and gas supply steel pipe for the fire protection disclosed by the utility model, the temperature-resistant, anti-flaming, anti-rusting and anti-corrosion modified epoxy resin layers are coated on the two sides of the steel pipes, so that the problems that the normal steel pipe and the galvanized steel pipe are easy to rust and scale, and the rusty layer and the dirt are easy to block a spray head are effectively solved, the use effect is good and the application range is wide.
Description
Technical field
The utility model belongs to the metal pipe technical field, is specifically related to a kind of fire supply and reaches to the gas composite steel tube.
Background technique
At present, the feedwater of structural fire protection system reaches and generally adopts common steel tube or Coating Steel Pipe to feed channel.The shortcoming of using common steel tube or Coating Steel Pipe to make fire protection pipeline is: easily get rusty, inner easily fouling, when fire alarm takes place when, iron rust and dirt in the pipe can stop up fire protection pipeline, extinguishing agents such as water, foam, carbon dioxide, dry powder, inert gas can be hindered, influence fire extinguishing effect more seriously makes fire-fighting system lose fire-extinguishing function concurrently.
For addressing the above problem, need provide a kind of and be difficult for getting rusty, less scaling, corrosion resistant fire supply and to the gas composite steel tube.
Summary of the invention
The utility model purpose provides a kind of fire supply and to the gas composite steel tube, is difficult for getting rusty, less scaling, corrosion-resistant long service life.
For achieving the above object, the technical solution adopted in the utility model is: a kind of fire supply reaches to the gas composite steel tube, comprises steel pipe, and the inside and outside both sides of this steel pipe are equipped with the modified epoxy layer.Above-mentioned fire supply and to the interior outside of gas composite steel tube be difficult for getting rusty, less scaling, corrosion-resistant, the composite steel tube long service life.
In the technique scheme, the modified epoxy layer of described steel pipe inboard is coated on the inboard of described parent tube by Electrostatic Spray Technology.
In the technique scheme, the modified epoxy layer in the described steel pipe outside is coated on the outside of described parent tube by Electrostatic Spray Technology.
Preferably, described modified epoxy layer is made by the modified epoxy powder of redness.Described steel pipe is common steel tube.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. the utility model has heatproof, fire-retardant, non-corrosive, corrosion resistant modified epoxy layer in the inside and outside coating on both sides of steel pipe, solved effectively that common steel tube and Coating Steel Pipe easily get rusty, easily fouling, rusty scale and dirt easily stop up the problem of shower nozzle, and using effect is good, is suitable for extensive use.
Description of drawings
Fig. 1 is the utility model embodiment one sectional view;
Wherein: 1, steel pipe; 2, modified epoxy layer.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to shown in Figure 1, a kind of fire supply reaches to the gas composite steel tube, comprises steel pipe 1, and this steel pipe 1 is common steel tube.
The inside and outside both sides of described steel pipe 1 are equipped with modified epoxy layer 2.Described modified epoxy layer 2 is made by the modified epoxy powder of redness, and is high temperature resistant, antistatic.
In the present embodiment, internal layer modified epoxy layer is coated on the inboard of described parent tube 1 by Electrostatic Spray Technology.
Outer modified epoxy layer is coated on the outside of described parent tube 1 by Electrostatic Spray Technology.
The utility model has heatproof, fire-retardant, non-corrosive, corrosion resistant modified epoxy layer in the inside and outside coating on both sides of steel pipe, solved effectively that common steel tube and Coating Steel Pipe easily get rusty, easily fouling, rusty scale and dirt easily stop up the problem of shower nozzle, and using effect is good, is suitable for extensive use.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
