General outdoor water supply stainless steel tees should be dug well for drainage trenches, water collection wells, and pumping equipment, such as pumps, hoses, etc., in order to pump water during construction in rainy days, especially in the basement. The soil should be backfilled in time after completion.
What should we do in a special period?
(1) When asbestos cement interface is used, hot water mixing materials should be used, but the water temperature should not exceed 50℃.
(2) When the temperature is lower than -5℃, the above two data interfaces are not suitable.
(3) After the interface is completed, it can be cured by sealing with muddy mud mixed with salt water, and covering the grass curtain.
(4) During the pressure test, the exposed pipes or connections should be tightly covered with grass curtains, and the pipe body without the connection should be backfilled. After the pressure test is completed, the water should be drained as soon as possible. Do well the preparation work before pressure test and drainage work after pressure test.
The steel pipe has a hollow cross-section, and is widely used as a pipeline for transporting fluid. Such as pipelines for transporting oil, natural gas, coal gas, water, and certain solid materials. Compared with solid steel such as round steel, steel pipe has a lighter weight when the flexural and torsional strength is the same. It is an economic cross-section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, and bicycles. Frame and steel scaffolding for building construction.
The use of steel pipes to make ring parts can improve the utilization rate of data, simplify the production process, save data and processing time, such as rolling bearing rings, jack sleeves, etc. At present, steel pipes have been widely used. Steel pipe or a variety of conventional pipe fittings can not lack of information. Steel tubes can be divided into round tubes and special-shaped tubes according to different cross-sectional shapes. Because the circle area is the largest when the circumference is flat, a circular tube can transport more fluid. In addition, when the circular cross-section receives internal or external radial pressure, the force is relatively uniform. Therefore, most steel tubes are round tubes. However, round tubes also have certain limitations.
The above information is provided by pipe tee suppliers.
