Concrete Pump Hose with Abrasion Resistant Tube and Cover

Hebei Qianli Rubber Products Co., Ltd. is the professional manufacturer of complete concrete pump hose products in China. We have established long-term cooperation relationship with many companies and we have exported our products to many countries. What's more, we have won very high reputation among many customers due to our high quality products and excellent after-sale service.

Our concrete pump hose products include steel wire reinforced concrete pump hose, fabric reinforced concrete pump hose and gunite hose. They are widely used in concrete placement industry and gunite hose is used to transfer dry sand and cement in concrete repair.

Steel wire reinforced concrete pump hose, fabric reinforced concrete pump hose and gunite hose have the same structure. They are all composed of three parts: tube, reinforcement and cover. The specific materials of tube, reinforcement and cover of different kinds of hoses are shown below.

Qianli Concrete Pump Hose
Bridge, Building, Tunnel, Swimming Pool Construction

Steel wire reinforced concrete pump hose
The tube and cover of steel wire reinforced concrete pump hose are made from high quality chloroprene rubber, making the hose resistant to abrasion, weather, ozone, cutting and corrosion. The reinforcement is made from multiple layers of high tensile steel wires meeting international standard. And reinforcement makes the hose work well in high pressure environment. It is mainly used to convey highly abrasive concrete in the construction of building, bridge, tunnel and swimming pool.

Fabric reinforced concrete pump hose
The tube and cover of fabric reinforced concrete pump hose are made from high quality chloroprene rubber, making the hose resistant to abrasion, weather, ozone, cutting and corrosion. The reinforcement is made from multiple layers of polyester cords. And this type of concrete pump hose can reduce the workload of workers. Besides, it has less harm to workers. It is also used to convey concrete in many concrete projects.

Gunite hose
The tube and cover of gunite hose are made from high quality NR synthetic rubber, making the hose resistant to weather, ozone, corrosion and abrasion. Reinforcement is made from two layers of high tensile steel wires or polyester cords. It is mainly used to convey dry sand and cement in concrete construction industry, such as mining reinforcement, swimming pool, ground stabilization, decorative concrete, refractory liners and so on.

There are some matters need to attention about concrete pump hose:

• The selection of concrete pump hose and the installation layout should be reasonable. Avoid unnecessary bending.
• Concrete pump hose is only used to convey highly abrasive materials, such as concrete, dry sand, cement and lime. It cannot be used to convey other materials, such as organic fluids, acids and alkalis. Otherwise, its service life would be shorter.
• The maximum temperature range of concrete pump hose is -40°C to +120°C.
• Concrete pump hose and hose assembly should not be used in the kink condition.
• Concrete pump hoses should be handled carefully in the loading and unloading process.
• Do not load concrete pump hoses together with acids, alkalis, oils, organic solvents, inflammable and explosive materials. Concrete pump hoses should not touch sharp products directly.
• The storage period of concrete pump hoses should not exceed 2 years. The hoses should be used follow the principle of "first in, first out"; to prevent the hoses quality being affected for the long time storage.
