Using
Connecting two pipes of the same or different nominal diameter so that the pipe can turn in  *0 °, *5 °, **0 °, and various degrees.
Bending radius less than or equal to 1.5 times of the pipe diameter belongs to elbow, greater than 1.5 times pipe diameter belongs to the bend pipe.
 
 
 
Concrete pump pipeline
Pump pipe is hollow section, most of them is used for conveying fluid and specializes in conveying concrete, etc. Pump pipe is a new type of construction engineering accessories which simultaneous appearances with concrete pump, it greatly improves the efficiency of construction. Pump pipe generally falls into two kinds, respectively are **5mm and **0mm, and this both kinds have high pressure and low pressure. Outer diameter of low pressure model of **5 mm type concrerte pump is Φ**3 mm pipe, outer diameter of high pressure model is Φ**0 mm pipe. Outer diameter of low pressure model of **0 mm type pump pipe isΦ**9 mm pipes, outer diameter of high**0mm pressure model isΦ**8 mm pipe. Pipe joint of pump pipe is through special processing and welding connected with pipe and each pipe is connected by pipe clamp with precision casting technology.
According to usable range, concrete pump is divided into two kinds, pump truck pipe and pit pump pipe. Pump truck pipe is made from cast steel casting, which includs boom tube, hinged elbow, reducer and bend. Pit pump pipe, common *0 # carbon steel, is strip steel with hollow section and no seams around, it is processed by the fluid pipe or straight seam pipe.
