A Method to Prevent Bursting of Stainless Steel Hot Water Pipe
In cold winter, in order to prevent water pipe bursting, some necessary measures should be taken to prevent stainless steel hot water pipe bursting. The simpler method is to close the water valve and put the water in the water pipe. Drain the water to prevent freezing. At the same time, once the water pipe is found to be frozen, don't rush to pour hot water, suddenly, larger temperature difference will increase the probability of water pipe burst.
The correct way is to pour with warm water, or open the water valve to drain the water slightly. The slowly flowing water can bring the warm water from the ground to the water pipe on the ground. The flowing water will slowly melt the ice and dredge the pipe. At the same time, The heat preservation of the water supply pipe and the water meter is also very important. You can wrap the heat preservation material around the water supply pipe and the water meter, or wrap several layers with plastic film for better heat preservation effect.
Causes of surface defects of thin-walled stainless steel hot water pipes
1. Uneven polishing and passivation
After manual polishing, pickling and passivation treatment, especially large-area blunt parts, it is difficult to achieve uniform The effect cannot achieve the ideal uniform surface.
2. Pickling is not in place
Pickling paste may be difficult to remove the black scale produced by plasma cutting and flame cutting.
3. Scratches caused by human factors
In the process of hoisting, transportation and processing, bumps, dragging, hammering, etc. can damage thin-walled stainless steel water pipes, which is also the main reason for water pipe surface defects.
4. Equipment Factor
There is a defect because the water pipe is scratched by processing or lifting equipment.
stainless steel hot water pipe rust solution
stainless steel hot water pipe rust removal can be divided into physical rust removal and chemical rust removal, generally stainless steel pipes are rusty, basically, tools are used to remove oxides, such as grinding the surface of steel with steel wire brushes and other tools, which can remove loose or upturned oxide scale, rust, welding slag, etc. As well as the pipe after drawing, we can use the drawing ball to manually draw the rusty part again to achieve the purpose of rust removal.
Chemical derusting method uses chemical and electrolytic pickling to remove oxide scale, rust and old coating. The principle of chemical derusting is that pickling liquid reacts with oxides on the surface of pipes to achieve derusting effect. Pickling paste or pickling spray is used to assist the repassivation of corroded parts and form chromium oxide film to restore its corrosion resistance. After pickling, all pollutants and acid residue should be removed and rinsed with clean water properly, after treatment, re-polish with polishing equipment and seal with polishing wax.
