August 30, 2019

Complete set of equipment for quenching inner wall of concrete pump pipe:

range of work : Diameter 125mm~150mm

Processing length:200mm~3500mm

working efficiency :10pcs/H(Subject to 3000mm pipe)

If the customer has special requirements, can be customized production.

 

1. Brief introduction:
At present, the concrete pump pipes in our country generally adopt two kinds of materials: 20# steel or alloy structural steel,In the process of production, because of the wear of concrete to the inner wall, the service life of these two kinds of steel pipes is very short, which is very wasteful.

According to the market demand, Zhengzhou Kechuang Electronics Co., Ltd has developed the quenching machining center of the inner wall of concrete pump pipe.

By quenching the inner wall of pipeline, the hardness of inner wall can reach HRC58-62.,And the pipeline outside has good plasticity, which can increase the service life of the pipeline by three times, and has a very high performance-price ratio.,For the use of our equipment pipeline production enterprises to bring rich profits. Purchase of our equipment within half a year can be recovered equipment investment, pipeline production enterprise product upgrading is the ideal choice.
