Introduction: Currently in China,the Concrete Pump pipe usually adopts the 20#steel or Alloy structural steel two material.During the production process,because of the  Wear and tear on the inner wall of concrete the lifespan of the two kinds of steel are all very short,also have the serious Waste.Zhengzhou Kechuang Electronic Co.,Ltd according to the need of the market, have successfully reseached the Concrete pump pipe inner wall quenching/hardening Machining Center.Through the pipe inner wall surface quenching treatment,So that the inner hardness reaches HRC58-62.The outer pipe also has a great plasticity,and this makes the pipe service life increased 3-5 times.It has the highly cost-effective, and also has brought huge profits for the company's pipeline equipment manufacturers. Purchase of our equipment, our company can be recovered within six months, investment in equipment is a pipe manufacturing enterprises an ideal choice of product upgrades.
