Concrete high pressure concrete pump pipe quality is better than low pressure concrete pump pipe
The concrete pump pipe is divided into a high pressure pump pipe and a low pressure pump pipe according to the pressure to be carried. The pressure of the high pressure pump pipe is generally about 20 mpa, and the low pressure pump pipe is below 10 mpa. The high pressure pump pipe generally uses high and high standard materials. At present, the high-pressure models commonly used for concrete have an outer diameter of Φ140 and an outer diameter of Φ168. The low-pressure concrete pump pipe has an outer diameter of Φ133 and an outer diameter of Φ159.

The flange of the high pressure concrete pump pipe and the flange of the low pressure concrete pump pipe are different from the 157 flange. The material is made of high manganese steel. The flange of the low pressure concrete pump pipe and the flange of the high pressure concrete pump pipe are also the same. 148 flange, low pressure concrete pump pipe The material is 20# carbon steel, which is mainly used as a concrete pump pipe. It is made of fluid tube or straight seam tube.

The difference between a concrete high pressure concrete pump pipe and a low pressure concrete pump pipe is that the pressure is different.
The concrete concrete pump pipe can be divided into a high pressure concrete pump pipe and a low pressure concrete pump pipe according to the pressure.
A spiral welded concrete pump pipe is a concrete pump pipe that is welded to a steel strip or steel plate and deformed into a circular shape, a square shape, etc., and has a seam on the surface.

According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency electric resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe and so on.
According to the shape of the weld, it can be divided into a straight welded pipe and a spiral welded pipe.
Electric welding concrete pump pipes are used in oil drilling and machinery manufacturing.
The furnace welded pipe can be used as a water gas pipe, etc., the large diameter straight seam welded pipe is used for high pressure oil and gas transportation, etc.; the spiral welded pipe is used for oil and gas transportation, pipe piles, piers and the like.
The welded concrete pump pipe has lower cost and higher production efficiency than the seamless concrete pump pipe.
Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development.
The strength of the spiral welded pipe is generally higher than that of the straight welded pipe. It is possible to produce a welded pipe with a large diameter by using a narrow blank, and it is also possible to produce a welded pipe having a different pipe diameter by using a blank of the same width.
However, compared with the straight pipe of the same length, the weld length is increased by 30 to 100%, and the production speed is low.
Therefore, most of the smaller diameter welded pipes are straight seam welded, and the large diameter welded pipes are mostly formed by spirally bending the hot rolled strip by spiral welding, and the inner and outer seams are automatically welded by submerged arc welding. The welding is made into a spiral seam concrete pump pipe (also called a spiral welded tube, a spiral tube).
The spiral concrete pump pipe can be widely used in the production of large-diameter concrete pump pipes for the following reasons: 1) As long as the forming angle is changed, it is possible to produce concrete pump pipes of various calibers with strips of the same width; 2) because of continuous bending forming Therefore, the length of the fixed length of the concrete pump pipe is not limited; 3) the spiral shape of the weld is evenly distributed throughout the circumference of the concrete pump pipe, so the concrete pump pipe has high dimensional accuracy and high strength; 4) easy to change size, suitable for small batches Production of multi-variety concrete pump pipes
