HDPE double wall steel pipe equipment is specially used for the production of HDPE double wall steel pipe plastic pipe winding equipment.

 

 Double-wall steel pipe Description:

HDPE winding double wall steel-plastic composite pipe is in polyethylene (PE) and galvanized steel as a raw material, PE materials forming it into two t-shaped plate, galvanized materials for w-type and embedded in the slot between the two PE Strip, then PE on the external coating material and the formation of the third generation of a new steel-plastic drainage pipe.

Double-wall steel pipe advantages:
1.Because the metal strip strengthening design in HDPE plate belt around the molding on both sides of the groove,and steel mills processed into I-bar-shaped "u", and boards with protruding arches, together form a unified wall outer planes, and consists of a steel band accepts external pressure, high ring rigidity.

2.HDPE plate composed of plastic drainage pipe inner wall and the outer wall. Therefore, carry forward the soft plastic, is one of the flexible pipe, laying quality is above the average, to "pipe soil interaction" under various load. The thickness of the wall is uniform, and there is no thin link.

3.Simple processing, easy operation, pipe has good stability, strip and plate belt using the same HDPE plastic, surround the strip in pipe making machine heating welding quality is guaranteed, and after rolling cooling weld and the average seed setting, when the inner wall of the pipe welded into a whole, in the outer wall of the groove placed I-shaped steel strip, again from the outside by a melting of HDPE coated smooth, good stability and no leakage.

4.Erosion resistance and long service life. First, steel belt use after anti-corrosion treatment of galvanized steel, the second, the strip is completely coated in the outer wall by the HDPE a groove, outside use HDPE completely covered, any time strip won't run to the outside to contact with air to avoid strip rust, oxide.Thirdly, strip processing process neither glue nor paint and plastic, just place it in than the "plastic box" this will not be inconsistent because of thermal expansion coefficient of steel, plastic and strip show in the air.

5.save freight, there are large projects, the equipment can be transported to the scene near the manufacture, which greatly saves the freight.

6.Pipe length can be arbitrary adjustments. Because the pipe forming, instead using raw materials, but semi-finished HDPE strip and shaped strip,you can continue,  pipe can be asked to do very long, even between the two reflection well, just a pipe, eliminating a lot of joints, reducing leakage, and cost savings.

7.thin wall, and low cost.For its modulus of elasticity plastic 200 times, while HDPE is the price of steel, two or three times.Thus, made with high strength steel pipe frame, the wall can be dramatically reduced without affecting the quality of pipe, such as SN8, φ 800 pipes, common hollow-wall round pipe wall thickness up to 50mm, and the double wall steel pipe wall thickness is only 22mm, and the steel with a thickness of only 7mm.

8.diameter adjustable: in the pipe forming machine, surrounded on the circumference of the disc diameter determines the diameter, it is adjustable, it determines the pipe inner diameter.The same kind of board can be made into pipes of different diameters, which can be said to produce a large product of flexibility.

9.pipe easy cutting, specially set cutting machine, just cut in the plastic board belt, easy cutting.

10.the spigot connection: about large-diameter drainage pipe, we make use of rotational moulding method, processing spigot joints not only has to ensure that no leakage at the joints and fast convergence device.

11.the strong impact resistance and breakage.This is currently known by the most strong drainage, not just hammer you can't beat, rock drum bag exterior and interior walls of the pipe is not damaged.
