描述

Concrete pumping pipeline is called concrete pumping pipeline because concrete is referred to as concrete (tng). It is easy to understand that the pump pipe is a new type of construction fittings with the emergence of concrete pump. Its appearance greatly improves the efficiency of construction. It changes the operation mode that used to need a barrel or bucket of artificial or crane to quickly convey concrete to the place where pouring is needed. The construction efficiency has been improved nearly a hundred times. Pump pipes are generally divided into 125 cm and 150 cm, and the two have their own high and low pressures. The low pressure type of 125cm pump pipe is 133cm pipeline with outer diameter, and the high pressure type is 140 cm pipeline with outer diameter; the low pressure type of 150cm pump pipe is 159cm pipeline with outer diameter, and the high pressure type is 168cm pipeline with outer diameter. The pipe head of pump pipe is a specially processed pipe joint, which is connected with the pipe body by welding. The connection of each pipe is connected by a pipe clamp manufactured by the investment casting process. Pump pipe can be divided into towing pump pipe and ground pump pipe according to the scope of application. The towing pump pipe includes boom pipe, hinge elbow, different diameter pipe and elbow pipe, which are cast with cast steel. Ground pump pipe is ordinary 20 # carbon steel, made of fluid pipe or straight seam pipe.
