Those who are familiar with the distinction between high and low pressure know that it refers to the drag pump tube. Concrete pump pipes, commonly known as ground pump pipes, are classified into low pressure, high pressure, and even ultra-high pressure according to engineering requirements. For slightly larger concrete conveying projects, concrete conveying pumps are basically required. When using pumping machinery, the safety and smoothness of the project must be ensured first, and appropriate mechanical accessories should be used according to the actual situation. The reason why ground pump pipes are divided into high pressure and low pressure is definitely due to differences in usage, process, accessories, price, installation, and various parameters.

        The difference between environmental and installation factors

        In terms of environment and installation, high-pressure pump pipes must withstand higher pressure during operation than low-pressure pump pipes. For example, in high-rise buildings, railway bridge piers, high-speed bridge piers, and other projects that require high pressure values, high-pressure or even ultra high pressure pump pipes must be used to ensure completion. When connecting the concrete trailer pump to the pump pipe at the beginning, even when the pressure value is low or medium, it is recommended to use high-pressure pump pipes as much as possible because this location is under high pressure. For example, in a high-rise building with more than 20 floors, if a concrete trailer pump is used to transport the material, high-pressure or ultra high pressure pump pipes must be used at the beginning, and the later connected pipe bodies can only use high-pressure ones. The connection method and accessories must be carefully considered. Selection. *One is to ensure the safety hazards after the increase of pressure in the later stage, and the other is to avoid the trouble of replacing the pipe body due to insufficient pressure in the later stage. Low pressure pump pipes only facilitate the transportation of concrete to the required location while saving labor, so the pressure requirements are lower than those of high-pressure pump pipes. By calculating the transportation distance, the pipe body can be selected.

        The difference between craftsmanship and accessories

        There are also significant differences in process and accessories. The body of DN125 high-pressure pump pipes is generally 140mm, and the wall thickness is divided into 6mm, 8mm, and 10mm according to the pressure level. The connecting flanges used are also 175mm or 194mm enlarged flanges, in order to make the connection more secure and sealed. The fixed pipe clamp is also a specialized pipe clamp that matches the flange. The DN150 pipe body is a 168mm ultra-high pressure pump pipe, with a wall thickness of 12mm and flanges of 230mm or 306mm. Simple pipe clamps are not sufficient for connecting ultra-high pressure pump pipes, and double flanges are generally used to connect and fix them with bolts and nuts. High pressure pump pipes, regardless of the special requirements for pipe body and wall thickness, are designed to meet the high pressure requirements of construction. The operational requirements for low-pressure pump pipes are far less stringent than those for high-pressure pump pipes, and the pipe body and accessories are naturally not as strict as those for high-pressure pump pipes. The low-pressure pump pipe body is 133mm, the wall thickness is 5mm, and the flange can be 148mm.

Both high and low pressure have their significance, and there are relative differences in process and price. The bent and straight pipes of the ground pump are also corresponding.
