The concrete pump tube is one of the most important wearing parts on concrete pumps and concrete pump trucks. For the boss who specializes in renting concrete pumps and concrete pump trucks, it is no doubt that the best concrete pump tube can be bought with the least amount of money. Is the best choice. But the products are often the same, you get what you pay for, but for buyers, the skills to identify good and bad pump tubes are still indispensable. For purchases that have just entered the concrete pump pipe industry, you may feel that there are many types, thicknesses, and materials of the pump pipes, and sometimes they are confused. When purchasing, they bought the ones with cheaper prices, and then used them after returning. I feel that the pump tube is not working until it is finished, so next I will teach you how to identify the pump tube.

The most commonly used concrete pump pipes are those used on concrete delivery pumps or truck-mounted pumps. The most commonly used ground pump pipes are SANY high-pressure ground pump pipes and ZOOMLION, PUZTMEISTER, SCHWING low-pressure ground pump pipes, high-pressure ground pump pipes with two-end flange type 157, and low-pressure pump pipes with two-end flange type 148.

In terms of material, the most commonly used ground pump pipes are: straight seam pipe (Q235), seamless pipe (20# or 35#). So before purchasing pump tubing, you must know which material you purchase. The thickness of the pump tube is the most commonly used: 4.5mm, 4.75mm, 5mm. The weights of the three thicknesses of the pump tube are: about 43kg, about 46kg, about 48kg, and the difference between the upper and lower sides cannot exceed 2kg, so if the weight is weighed Know the quality of the tube. In addition to the weight and material, there is another one that depends on the quality of the flanges at both ends of the pump tube, because the flanges are good or bad, and they can also come here. The last thing is to think about the welding process of the flange and the pump tube. If the welding joint is not smooth, it will lead to the poor sealing of the pump tube and easy tube burst accidents.
