Full bore structure and reduced bore structure: in order to meet the different needs of users, our company's ball valve products have two series: full bore and reduced bore. The channel inner diameter of the full bore ball valve is the same as the pipe inner diameter, which is easy to clean. The weight of the reduced bore series ball valve is relatively light, but the flow resistance is only about 1/7 of that of the stop valve with the same diameter. Therefore, the reduced bore series ball valve has a broad application prospect.

Standard for length of flexible waterproof casing
The inner diameter, outer diameter of the casing and outer diameter of the flange are regulated, and the specifications for steel pipes and various indicators of steel pipes are suspended. The waterproof casing atlas has clear rules, and the length can be suspended according to the project demand. Usually, the need to confirm the extension part of special projects. The length is mainly determined by the wall thickness
The length of flexible waterproof casing is 1500mm and 2000mm respectively, which is mainly based on the theoretical needs of customers. For example, two walls need to install waterproof casing. The need to stop customization according to the special request. 02s404 waterproof casing atlas is explained according to the thickness of 300mm wall, but in the theoretical construction, it is not always the standard wall thickness, so the length is determined according to the design request and wall thickness of the project
The new waterproof casing consumed by our factory mainly adopts Q235 steel seamless steel pipe, which effectively improves the reliability of the wall pipe in the application process. After welding, it can effectively ensure the separation of the waterproof wing ring from the seamless steel pipe, greatly improving the rigidity of the steel pipe. In the concrete embedding project, the pressure resistance of the casing can be better applied. External epoxy resin coating can be applied
It can effectively ensure that the environment will not be affected in the application process. The corrosion resistance of seamless steel pipes will be kept outdoors from time to time. In particular, the modified epoxy resin layer can be better used in humid and corrosive environments. Our waterproof shell, flexible waterproof shell and external application of epoxy resin coating can effectively ensure that the environment will not be affected in the application process, Moreover, the corrosion resistance of seamless steel pipes is always kept outdoors, especially the modified epoxy resin layer can be better used in humid and corrosive environments
