What Is Concrete Pump Pipe Used For
As we all know, concrete pipe is used for conveying concrete mixture to different construction areas.
Because of concrete pump pipe, concrete pumps can deliver different kinds of concrete materials to almost any construction site on any terrain. No matter at narrow tunnels, ditches, moutain embankement dam with rugged terrain, or large scale long-distance airport, railway station construction, high-rise building construction, small-sized civil building project, concrete pipes can always guide concrete raw materials into every application area.
Through resonable and flexible pipeline layout, the project construction group can greatly improve the construction efficiency and quality, and create more benefits.
How Much Is Concrete Pump Pipeline
Concrete pump pipeline price is various depending on different types, materials, specifications and brands. Normally, the market price of 100m streight steel pipe is about $10,000.
Generally, once customers purchase a concrete pump machine with standard configurations, LUTON will provide pipes with certain length, types and accessories, to ensure that the pump machine can quickly put into use as soon as possible.
Certainly, concrete pump pipe belongs to a kind of consumables in the pump equipment, whose service life is limited. In order to ensure the pumping efficiency and construction safety, it is necessary replace pipeline in time after a certain period.
How Many Types Of Concrete Pump Pipeline
Concrete pump pipelines vary with different classification methods.
Concrete trailer pump pipeline, concrete pump truck pipeline and fine stone pump pipeline are from different usage on various pumping machines.
Straight pipe and elbow pipe are for different shape needed onsite.
There are also different materials to made of concrete pump pipeline:steel pipe, rubber hose, plastic pipe and so on.
At present, the most widely used concrete pump conveying pipeline is uaually made of high strength steel material. This kind of material has good strength and durability, more high pressure resistance, more wear resistance, more effectively ensure the service life of the pipeline.
In order to meet different pumping pressures, the pipes are devided into high-pressure pumping pipeline and low-pressure pumping pipeline.
Specifications Of Concrete Pump Pipeline
The specification parameters of concrete pump conveying pipeline are important indicators that must be referred to when selecting the pumping pipeline to determine the conveying scheme. So, they are also the key factors for the smooth pumping progress and high quality and efficient pumping.

The material of concrete conveying pipe mainly includs steel pipe and rubber pipe. Steel pipe is divided into ordinary steel carbon pipe and alloy steel pipe. The material of ordinary carbon steel pipe is Q235, Q345, etc. The mateial of alloy steel pipe is 16 Mn. The rubber pipe is natrual rubber or synthetic rubber material.
In the pumping process, concrete is squeezed by the concrete pump and flows in the conveying pipeline, which requires the pipeline to have a certain pressure resistance and wear resistance.
The pipeline diameter usually ranges from 100mm to 200mm. The most common pipe diameter for LUTON concrete pumping pipe is 125mm.
Selection of pipeline diameter depends on the viscosity of concrete and transfer distance. To ensure smooth concrete flow in pipeline, concrete with a higher viscosity and concrete with a longer delivery distance require a larger pipe diameter.
Concrete pump pipeline is 1m to 6m long. LUTON Group provide pipeline length is uaually 3m, 2m, 1.5m or 1m.
Generally speaking, the shorter the concrete pipeline, the more stably concrete conveys. That is because short pipeline generates less flow friction. But if the pipeline is too long, more connectors are required, which may lead pipe leakage.
Pipe Wall Thickness
The wall thickness of concrete pump pipeline is usually between 5 -7mm, so, the standard wall thickness of the pipe adopted by LUTON GROUP is usually 5mm.
The thicker the pipe is, the stronger the pipe is, also can withstand higher pressure. But too thick pipe wall will reduce the delivery capacity of the pipe.
Pipe Bending Radius
For elbow pipes, bending radius are an important parameter besides material, diameter and wall thickness.
The size of the bending radius depends on the angle and the position of the pipe bending. The bending radius is usually 1.5-3 times the pipe diameter.
The most commonly used bending angles of LUTON GROUP concrete pump pipe are 45°and 90°.
Pipe Joints And Fittings
These accessories provide tightly connection of pipes and a reliable guarantee for the flexible laying of concrete conveying pipeline. And also they facilitate the installation and maintenance of pipelines.
High Pressure Hose
Concrete hose is usually used at the end of the concrete conveying line. It is made of SBR/NR rubber material reinforced with steel braids.
Unlike steel pipe, rubber hose has strong flexibility and can be controlled by manual operation to realize the final accurate placement position of concrete.

How To Place Concrete Pump Pipeline Onsite
On modern construction sites, concete is delivered by various pump equipment through pre-set concrete pump pipeline. How to place concrete pump pipeline onsite is one of the most important issue of concrete conveying scheme. There are some layout principles need to take into consideration before place concrete pipeline.
Under the circumstance of smooth concrete puming and normal concrete transmission, shorten the pipeline length and reduce elbow pipe number as possible as you can, to reduce the transmission resistance.
The pipeline layout is depended on the pumping pressure. Place new pipeline and high-pressure pipeline at the point with high pumping pressure. Check the pipeline timely to ensure normal working condition.
Different pumping directions need different layout methods. When the pipe is arranged downward, the drainage valve should be set at the top; When piping up, the length of the bottom horizontal section should be not less than 1/4 of the length of the vertical pipe, and not less than 1m. And the stop valve should be set in a certain position.
No matter the placing direction is horizontal, upward or downward, the concrete pump pipeline should all be fixed firmly, especially the elbow connecting points. The pump pipe fixation should not have any relationship with the formwork support, and the rubber between the pump pipe and the bracket.
The vertical pipe layout should be arranged according to the construction structure characteristics. Make full use of the column, wall, floor and vertical transportation machinery, equipment holes as the support and attachment point of the vertical pipe, gradually rise to the top, and keep the whole vertical pipe in the same straight line.
At the same time, convenient disassembly, easy troubleshooting, safe and reliable attachment should be also taken into consideration.
Reinforce properly all turns of the concrete pump pipeline, and add supports along the direction of pipe vibration. The elbow closest to the pump machine is effected by the greatest pumping force, so it should be hold tightly with a firm support to reduce vibration.
6.In summer, in order to reduce the temperature of concrete into the mold, the horizontal pipe in the open air should be wrapped and watered to prevent too fast slump loss of concrete at high temperature and cause pipe blockage.
FAQ About Concrete Pump Pipeline
Why Concrete Pipe Is Blocked
During pumping procession, one of the last problems the construction team wants to encounter is the blocked pipeline. Pipeline blockage not only affects the construction progress, brings economic losses, but also affects the service life of the equipment itself, bringing equipment losses.
There are multiple factors leading to pipe blockage：
- Improper operation during pumping
- The pipe connection errors
- Concrete or mortar segregation
- Slurry leakage at some part
- Unqualified concrete or mortar quality
- Sudden temperature change
In fact, to understand the cause of pipe blockage, operate according to the standard operation and maintenance of pumping equipment and transmission pipeline, can avoid most of the occurrence of pipe blockage.
How Long Can Concrete Be Delivered By Concrete Pump Pipeline
The concrete conveying distance is depended on many factors, including concrete material quality, pumping direction and pipeline layout methods, concrete pump equipment pumping pressure, conveying site environment and so on.
Generally speaking, concrete can be delivered horizontally by a concrete trailer pump through pipeline to the site away 1000m far.
And for the vertical conveying, concrete pump pipeline can direct concrete up to 60m high placing site.
How To Do For Concrete Pump Pipeline Maintenance
In order to reduce the danger and failure of pumping concrete and extend the service life of concrete pump machine, it is necessary to regularly inspect and correctly maintain the concrete pump pipelines.
1.To reduce uneven pipe wear and prolong the service life of pipe, the conveying pipe can be rotated regularly, every 3000m3 concrete pumping, rotate the straight pipe 120°clockwisely and the elbow pipe 180°.2.Check the wear of the delivery pipe frequently. When the pipe thickness is below the specified value, replace the pipe.3.Delivery pipeline should be installed without stress when pumping is closed.4.Clean the concrete pump pipeline after every pumping task.
How To Clean Concete Pumpline
After the completion of each pumping task, the timely cleaning of the residual concrete in the concrete pump pipeline is an important part of the maintenance, which is also the basic operation to extend the service life of the pumping pipeline and reduce the construction cost.
1.Preparation before cleaning pipes
Before cleaning, it is better to pump all of 0.5-1m3 mortar. Then stop the pump machine, remve the energy storage device pressure.
2.Put the water-soaked cleaning sponge ball into the pipeline, close the discharge door, and then fill the hopper with water and keep the water source constant. Then pump water until the cleaning ball is pumped out of the front end outlet of the concrete pump pipe.
3.Pay attention to the water in the pipe when it comes to the end of the washing, do not flow to the concrete pouring construction site, to prevent from affecting the concrete quality.
