On the market, concrete pump pipes are usually priced per piece, while ground pump pipes are generally priced at around 250 yuan per piece for every three meters. The price of pump pipes is closely related to the material, diameter, thickness, and production process of the pump pipes. Currently, the material of low-pressure ground pump pipes is usually welded from 20 # carbon steel seamless pipes and flanges, with a lower price; Although the material of the high-pressure ground pump pipe is also welded from 20 # carbon steel seamless pipe and flange, the pipe diameter is large, the thickness is high, and the flange is also different, so the price is higher.
