INFORMATION

19-20_1

At persent, the known inspecting & controlling in steel pipe embedded plastic pipe , Frequently , degumming and inspecting & controlling outlet tubes or improper operation in the process of construction and damage inside the plastic pipe , plastic pipe shed . So as to accelerate the corrosion of galvanized pipe.

Advantages ：

♣ Mechanical strength Big

Inner solid ring steel-plastic composite pipe and hot-dip galvanized steel pipe have the same excellent mechanical strength, have a strong resistance to impact, bending and pressure, and use pressure range is less than or equal to 1.6MPA.

♣ Anti-corrosion Good

The conveying fluid is effectively isolated from the metal body, and it is only in contact with the plastic layer, which has a good corrosion resistance effect and greatly prolongs the service life of the pipeline.

♣ Low fluid resistance

The inner wall of the inner solid ring steel-plastic composite pipe is smooth, the friction coefficient is small, the flow rate is fast and does not accumulate scale, and the fluid resistance is small.

♣ High hygienic performance

The plastic layer made of edible grade plastic meets the requirements of the national domestic water transmission and distribution standard, GB/T 17219.

Solve the following problems:

1. The problem of the plastic tube falling off due to thermal expansion and cold contraction.

2. Avoid the plastic pipe falling off caused by the long-term impact of the water flow on the port nozzle.

3. According to different sizes of steel-plastic composite pipes, set different sizes of pressure grooves. More convenient to install and use.

4. By pressing the groove, the inner fixing ring forms a reinforcing rib inside. Increase the firmness of the inner fixing ring setting.
