Q1.How many layers steel wires of this hose and how many steel wire of each layer is composed of?

A.Using four layers steel wire winding technology, each layer is composed of 100 steel wires,

which structure can guarantee the maximum combination of steel and rubber.

Q2.How many cubic feet concrete can be casted by one hose?

A. Many factors affect the casting cubic feet, such as the different aggregate between different counties,the different concrete pump and whether the hoses can be properly operating or not etc.

Gerenally speaking, under the normal condition of concrete pump, the delivery capacity is not less than20 thousand cubic feet or even up to 25 thousand.

Q3. Why does the wires always come out of the hose end? How to avoid ?

A: It is very important to bond the steel wire and rubber well. The degumming is often arised if the steel wire cannot bond closely with the rubber. In order to avoid this problem and lower the

degumming rate to a minimum we add a bonding layer above wear-resistant layer.

Q4. It's very dangerous when the hose head fall off, how to avoid this problem?

A: We make a 100% fall off inspection before the hoses leave the factory in order to make sure every hose can reach the operational requirement
