concrete pump pipe are generally divided into two types, 125 and 150. These two types have high pressure and low pressure. The low pressure type of the 150 type concrete pump pipe is a pipe with an outer diameter of Φ159, and the high pressure is a pipe with an outer diameter of Φ168. The low pressure type of the 125 type concrete pump pipe is a pipe with an outer diameter of Φ133, and the high pressure is a pipe with an outer diameter of Φ140; the pipe head of the pump pipe is connected to the pipe body through welding through a specially processed pipe joint, and the connection of each pipe is It is connected by a pipe card processed by a precision casting process.
The concrete pump pipe is a new type of construction machine used in conjunction with the concrete pump. It is like a robot. It can quickly and correctly transfer the concrete to the construction surface to any pouring part of the homework and carry out continuous pouring. With the traditional welding operation, many pipes with inner walls treated with anti-corrosion layers will be destroyed. His connection method has unique flexibility, which makes the pipeline have the ability of anti-shock, anti-shrinkage and expansion. Compared with the welding and flange connection, the piping system is not chaotic, and it is more suitable for temperature changes, thus protecting the pipeline. Pipeline valve components also reduce the damage to the structural components caused by pipe stress.
As a new type of construction machine used with concrete pump, 砼 pump pipe fittings are like a manipulator. The concrete on the construction surface can be quickly and correctly delivered to any pouring part of the homework surface and continuously cast. The upper hand of the two technologies.
The wear-resistant concrete pump pipe has excellent self-lubricating property, small friction coefficient and low fluid transport resistance. The molecular weight is large, the viscosity average molecular weight of ordinary polyethylene (PE) is only several hundred thousand; the ultrahigh molecular weight polyethylene (UHMWPE) has a viscosity average molecular weight of more than 1.5 million. Excellent chemical stability, except for a few solvents which are corrosive, common inorganic, organic acids, alkalis, salts and organic solvents (except naphthalene) are not corrosive to this material. Some users have even used ordinary pipes instead of crawling wear-resistant concrete pump pipe, resulting in catastrophic results.
