Abstract
A plastic coating steel tube and a connecting piece for fire control relate to the improvement of tubular materials, in particular the structure of fire-control tubular materials for water and gas supply. The technique content of the utility model is that: the surfaces of the internal and external wall of the steel tube and the connecting piece for fire control are coated with the plastic coating layer, which can be the modified epoxy powder dope with the fire retardant. The connecting piece comprises but without limit to a bending head, a joint, a tube cap and a three way or a four way. The surfaces of the internal and external walls of the tubular product are coated with different material, which can make the tubular product have the chemical resistance, and have the properties of fire retardant erosion, high temperature resistant and crib resistant. The service life of the utility model can reach to 50 years, and the upkeep is only 1/4 of the background technique, moreover the utility model can fully ensure the flow quality of the water and gas for fire control as well as the use effect, which avoids the waste of the energy source.
Description
Technical field
The utility model relates to a kind of to tubing, and particularly the improvement of pipe structure is used in fire-fighting with feedwater, gas.
Background technique
Before the utility model was realized, fire supply, tracheae material that people use adopted zinc-plated tubing, comprise pipeline and link.As everyone knows, described galvanized pipe antiseptic property in use is poor, owing to be subjected to the erosion of water for a long time, the internal surface of tubing easily gets rusty, and then stops up shower nozzle after rusty scale comes off easily; After the internal surface of pipe fouling, the internal diameter of tubing is dwindled or stop up, water delivery, tolerance are reduced even can't carry, influence using effect.If particularly above-mentioned condition occurs in the fire control and disaster rescue process, its consequence is then hardly imaginable.So only be 8-12 the working life of aforementioned tubes.
Technology contents
The purpose of this utility model is, by providing a kind of fire-fighting with plastic-coated steel and link, and then solved the problem that exists in the above-mentioned background technology.
Technical solution described in the utility model is: the inside and outside wall surface at described steel pipe and link is coated with coating layer.
Described coating layer can be for having the modified epoxy resin power paint of fire retardant.
Described link includes but not limited to elbow, joint, pipe cap, threeway or four-way.
Technique scheme makes the utility model compare with background technique to have tangible advantage:
1. because can be according to the purposes difference of tubing at the inside and outside wall surface of tubing, therefore be coated with the overlay of different materials, tubing had to have resistance to chemical attack at the same time or separately, the burn into of anti-the extinguishing agent is high temperature resistant and the fire of anti-grillage the and in the anticorrosion or flame resistant performance that has under water and the anhydrous state.Because above-mentioned advantage, the utility model is particularly useful for the fire-fighting water delivery, For Use Only in Case of Fire for gas.
2. plastic-coated makes the inner wall smooth of tubing, and resistance reduces greatly when making transporting water, gas, and fully dependable flow and using effect have been avoided the waste of the energy.
3. compare with background technique, can reach 50 years working life of the present utility model, and maintenance expenses only is 1/4 of a background technique.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
In the accompanying drawing, steel pipe 1, coating layer 2.
Mode of execution
Below in conjunction with accompanying drawing a kind of embodiment of the present utility model is specified:
In this example, the tubing that uses is steel pipe, and the tubing that relates in practice can also include but not limited to cast iron tube, galvanized pipe.Inside and outside wall surface at steel pipe 1 is coated with coating layer 2 uniformly.
Described coating layer can be for having the modified epoxy resin power paint of fire retardant.
Described in practice link can include but not limited to various elbows, joint, pipe cap, threeway or four-way.
Claims (3)
1. a fire-fighting is characterized in that with plastic-coated steel and link the inside and outside wall surface of described steel pipe and link is coated with coating layer.
2. fire-fighting according to claim 1 is characterized in that with plastic-coated steel and link described coating layer can be for having the modified epoxy resin power paint of fire retardant.
According to claim 1,2 described fire-fightings with plastic-coated steel and link, it is characterized in that described link can include but not limited to elbow, joint, pipe cap, threeway or four-way.
