What is a concrete hose?
Concrete hose is mainly used to transport concrete and grouting materials. It is suitable for concrete pump truck transportation and construction engineering machinery, including high-rise buildings, highways, tunnels, etc. Its main features are durability, wear resistance, strength and strong pressure resistance. In addition, concrete pump hoses have good sealing properties, which can effectively prevent problems such as sewage leakage.
Concrete hose construction
Tube: Black SBR/NR rubber, resistant to abrasion of concrete.
Reinforcement: Multiple textile cords & steel spiral.
Cover: Black, wrapped surface, SBR/NR rubber, weather and abrasion resistant.
Standard: ASME
Temperature range: -35℃ to 80℃
Working pressure: 55 bar/800 psi–85 bar/1230 psi
Burst pressure: 165 bar/2400 psi -200bar/3000psi
Safety factor: 3:1
Length: 40m-60m or customized
Connector type: Flange connector / Clamp connector / Quick connector
The working pressure of concrete delivery hose can reach 800 psi generally, tube inner diameter is from 1 to 8 inches. There are two main categories of reinforcement layers. The steel wire-reinforced rubber hose is mainly used to transport concrete, and the synthetic textile-reinforced rubber hose is mainly used to transport dry materials such as cement and powder. We can customize the size and material according to your needs.

Of course, it is also important to note that the concrete plaster hose must be cleaned after use, and there must be no concrete residue inside. Because once the concrete solidifies, the hose can’t be used. This will cause waste and increase costs greatly.
Why Choose Strongflex Concrete Hoses?
Strongflex has concrete hose production equipment, and has strict quality control from raw materials to finished products. The raw materials are made of high-quality synthetic rubber, SBR or NR, and AKRON wear resistance test will be performed to ensure the wear resistance of the inner layer of the hose when it is directly in contact with concrete. The outer rubber is made of weather-resistant, wear-resistant and aging-resistant synthetic rubber to ensure its long life when working outdoors.
The concrete hose produced by Strongflex has good flexibility and is easy to operate and lay. Direct OEM customization to meet diverse needs, steel wire reinforcement and line reinforcement can be selected as needed. High pressure resistance and burst prevention, to ensure construction safety.
In addition, it can be matched with different connectors for convenient and fast connection.
Concrete hose application scenario
Our concrete pumping hoses are widely used in various construction projects and high-intensity construction environments, with customers in many countries and regions.
High-rise building construction: Use pump trucks to transport concrete from the ground to dozens of floors high to ensure continuous and stable pouring.
Bridge engineering: Suitable for precise delivery of concrete in large-span bridge piers or narrow tunnels.
Foundation pouring and foundation construction: Soft and pressure-rsistant hoses can easily adapt to complex terrain and achieve efficient pumping.

How to choose the right concrete hose?
The selection of concrete delivery pipeline is crucial for construction efficiency and concrete quality. When selecting the concrete delivery hose, factors such as the concrete pouring scheme, pouring rate, working pressure, and working environment should be considered.
Select the appropriate concrete hose material and size according to the working pressure, working temperature, delivery volume, etc.
The size selection of the delivery hose needs to consider the concrete standard, the difficulty of pumping concrete, the average output per unit time, and the maximum particle size of coarse aggregate. Ensure that there is an appropriate relationship between the concrete delivery hose diameter and the maximum particle size of coarse aggregate to avoid problems such as pipe blockage. Pipe blockage is usually caused by larger stones stuck in the cross-section of the pipe, reducing the cross-sectional area and resulting in a reduction in the flow area. To prevent this, a mesh screen should be set at the discharge port to prevent large stones from entering the delivery hose.
Frequently Asked Questions (FAQ)
Q1: How long can the concrete hose be used?
A: Depending on the frequency of use and working conditions, it can generally be used for 6 months to 1 year; the reinforced hose can extend the service life to more than 1 year. It is recommended to clean it after each use and store it properly.
Q2: Which concrete pumps are suitable for the hose?
A: It is suitable for most concrete pump trucks, ground pumps, mixing pumps, small delivery pumps and other equipment. The connector can be customized according to your equipment.
