Concrete Pumping Hoses

Concrete pumping hoses tube is made of rubber, and reinforced layer in the middle . It can bear high pressure when concrete pouring. The concrete pumping hoses can work at extreme temperature from -50°C to 100°C. The concrete pumping hoses apply for Putzmeister, Schwing, Zoomlion, Sany, Cifa, Sermac, KCP, Junjin, Everdigm shotcrete trailer etc. It is important delivery element for concrete pouring.

 

The concrete pumping rubber hoses tube have 3 structure layers.

  • Inner rubber: Synthetic rubber, alkali resistance, aging resistance.
  • Reinforcement: Enhancement is made of wire steel layer or fabric reinforcement, and withstand high burst pressure.
  • External rubber: SBR Rubber. With high wear resistance, aging resistance, heat resistance.

Classify

Concrete pumping hoses have steel wire hose, fabric reinforcement concrete pump hose. Choose concrete pumping hoses according to different application engineering.

 

Steel wire concrete pump hose

The middle enhancement layer of concrete pump wire hose can be 2 layers, 4 layers. Steel wire hose has good comprehensive performance, and the steel rubber hose used for concrete pouring in engineering construction.
 

Fabric reinforcement concrete pump hose

Fabric reinforcement concrete pump hose have 2 layers, 4 layers, 6 layers, 8 layers as middle enhancement. It have 55Bar and 85Bar high pressure hoses. The more fabric layers, the more pressure the concrete pumping hose can withstand.

The tail ferrule is #20 steel with galvanized. It can be suit for SK end, and also offered HD end.

  • Standard SK148mm, apply for multiple brands concrete pump and countries.
  • HD157mm flange. Mostly used in USA, MEXICO, CANADA.
  • When using steel rubber hose, do not allow small bend radius.
  • If the inner rubber and the flange at the outlet is obviously worn, please replace it immediately to avoid danger.
  • It is forbidden to connect the pipe tube to the end hose, because the strength of the hose is not strong enough, and the hose may be broken when concrete pouring.

Concrete Pumping Hoses Feature

  • Has good oil resistance, heat resistance, aging resistance and wear resistance.
  • High wear resistance,  concrete pumping hose with high bearing pressure and superior pulse performance.
  • Durability, and the rubber hose has good bending resistance.

 

Application

The concrete pumping hoses connect with drag pump for pouring, and it also use for end of hose pumping.

  • If the concrete particle size is less than 25mm, the inner 125mm concrete hoses can be used;
  • If the concrete particle size is less than 40mm, the inner 150mm concrete hoses can be used.

Tips for concrete pumping hoses pouring

  • Before concrete pouring, check the pipe clamp first, and make sure the connector is seal.
  • When start or stop concrete pouring, the concrete pumping operator should contact with concrete hoses worker. 
  • The boom have more power strength, the end hose worker should not against the boom direction.
  • It shall be used together with vibrator to ensure the concrete pouring is dense.
  • It is best to place the clamp coupling on the concrete pumping hoses skid plate, this will avoid scratching the hose when movement.
