Alloy pipe is a kind of seamless Steel Pipe, its performance is much higher than that of general seamless steel pipe, because this type of steel pipe contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance performance is much better than other Steel pipe, so the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries.

Due to the fact that the water level in deep wells is below 50 to 60 meters from the ground, the borehole wall is more uneven. Manual measurement with a measuring rope hanging buoy falling into the water, measuring the rope to determine the water level. However, the buoys entering the water need to be judged by personal experience. The pontoon is easy to dock on the surface of the surface of the well and the measurement is inaccurate. In the second half of July, employees of the second water supply plant of the plant tied parallel wires to the measuring ropes and placed weights in the wells. The resistance of the wire not entering the water is infinite, and the contact with the water surface forms a path, and the resistance becomes 2 to 3 ohms, and the metering rope can measure the accurate water level.
Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.Most commonly, the phrase "alloy steel" refers to low-alloy steels.
The biggest advantage of the alloy steel pipe is 100% recycled, which highly meets our national`s strategy of environmental protection, energy and resource saving. Alloy steel pipes have hollow section, which can be used for conveying fluids, such as conveying oil, gas, water and some solid materials, etc.
Qilu water supply and drainage factory self-made measuring instrument to accurately measure the water level
In the measurement of the depth of underground deep-water wells, the self-made water level measuring instrument of Qilu Water Supply and Drainage Plant has been measured accurately in practical applications and has achieved good results. Currently, it has been promoted and used in this plant.
