How to clean the rust produced by alloy steel pipe
At present, the proportion of alloy steel pipe consumption in China's total number of steel is only a part of the country, alloy steel pipe application field expansion for the development of the industry to give a wider area, so improve the application time of alloy steel pipe, it is necessary to reduce steel pipe rust, corrosion, so today Xiaobian to share with you is how to rust alloy steel pipe, I hope to have a certain function for you.
Cleaning method of steel pipe rust
For the construction technology of epoxy, ethylene, phenolic and other anti-corrosion materials commonly used in alloy steel pipes, the standard is to achieve nearly white steel pipe surface
According to practice, it is confirmed that the rust and other dirt fully meet the adhesion standards of the anti-corrosion layer and alloy steel pipe, and the spray rust removal process can be stable and safe with low cost to achieve the quality of nearly white grade standards.
In order to achieve satisfactory function of the rust removal function, it is necessary to select wear-resistant materials and single-layer epoxy according to the hardness of the alloy steel pipe surface, the initial rust level, the standard surface roughness, the type of coating, etc
Two or three layers of polyethylene coating, in order to achieve satisfactory rust removal function, must use steel sand and steel pellets mixed wear-resistant materials. Because the steel shot has the function of strengthening the steel surface, and the steel sand has the function of etching the steel surface.
To obtain the distribution of symmetrical cleanliness and finish, the design of particle size and ratio of wear-resistant materials is very critical, because excessive finish is easy to cause the corrosion protection layer to thin at the peak of the anchor grain, and because the anchor grain is too deep, it is easy to produce bubbles in the corrosion protection process, seriously endangering the performance of the corrosion protection layer
Before the spray cleaning, the oil and debris on the alloy steel pipe layer can be removed, and the pipe body can be heated to 45-65 ° C, so that the surface of the alloy steel pipe can be maintained dry, because the surface of the alloy steel pipe does not contain grease and other dirt, so it can also strengthen the function of rust removal
Application of alloy steel pipe
Compared with solid steel such as round steel, the bending and torsional strength is the same, the weight is lighter, alloy steel pipe is an economic cross-section of steel, widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and construction of steel scaffolding.
The manufacturing of ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sleeves, etc., currently has been widely used to manufacture steel pipes. Alloy steel pipe is an indispensable material for all kinds of conventional weapons, and the barrel and barrel of the gun must be made of steel pipe.
