Abstract
The invention provides a steel tube producing method. Make decontamination and rust cleaning on the steel tube by buck and dilute acid, process by solvent and dry, then place the steel tube in heat galvanizing tank for 1-2 minutes and take out the steel tube, and then make air cooling and surface passivation to obtain the finished product. It can save Zn by 35-40%.
Description
Technical field
The present invention relates to a kind of steel tube producing method.
Background technology
The galvanized steel pipe of market sale now is in the equal pot galvanize of surfaces externally and internally, sometimes internal surface and do not require anticorrosionly, internal surface has been done rotproofing can play side effect on the contrary, to sum up the galvanized steel pipe of surfaces externally and internally soaking, not only can cause the metallic zinc waste, also can not make the user satisfied.
Summary of the invention
The purpose of this invention is to provide a kind of outside surface and make antiseptic steel pipe steel pipe, and this steel tube producing method.
The object of the present invention is achieved like this: the steel pipe that needs to handle passes through buck, diluted acid carries out the decontamination rust cleaning, after handling and dry through the liquation of preparing by the miscellany of ammonium chloride and zinc chloride again, the two ends of steel pipe place under the pipe clamp clamping of hollow in the Thermal zinc plating bath of fusing zinc, took out through 1-2 minute, again through blowing ring outward, blow outside that the inwall of ring distributes with steel shaft under the effect of the air that becomes 45 apertures of spending to blow out, make outer wall of steel pipe zinc coating thickness unanimity, steel pipe promptly must be asked product through the air cooling surface passivation again.
Compare with existing steel pipe by the product that the method for the invention is made, its internal surface no longer pot galvanize can be saved zinc 35-40%, has satisfied different requirements of customers.
Description of drawings
The present invention does not have accompanying drawing.
Embodiment
Embodiment 1:
Steel pipe through buck or diluted acid decontamination rust cleaning, after the solution of preparing via the miscellany of ammonium chloride and zinc chloride carries out the solvent treatment oven dry again, under the pipe clamp clamping of two hollows, place in the Thermal zinc plating bath, took out through 1-2 minute, again through inwall be distributed with steel shaft when apertures outer that is 45 degree blows ring, under compressed-air actuated effect, make hot galvanized layer thickness unanimity, after the air cooling surface passivation, promptly get this steel pipe.
Claims (1)
1, a kind of steel tube producing method, it is characterized in that: the steel pipe that needs to handle passes through buck, diluted acid carries out the decontamination rust cleaning, after handling and dry through the liquation of preparing by the miscellany of ammonium chloride and zinc chloride again, the two ends of steel pipe place under the pipe clamp clamping of hollow in the Thermal zinc plating bath of fusing zinc, took out through 1-2 minute, again through blowing ring outward, blow outside that the inwall of ring distributes with steel shaft under the effect of the air that becomes 45 apertures of spending to blow out, make outer wall of steel pipe zinc coating thickness unanimity, steel pipe promptly must be asked product through the air cooling surface passivation again.
