Today, let's talk about HDPE reinforced winding pipe type B, also known as carat tube winding reinforced pipe (type B pipe), this product uses German equipment and technology, using high-density polyethylene (HDPE) as the raw material of the product, winding in a hot melt state, and demolding after natural cooling. What are the characteristics of HDPE reinforced spiral wound pipe B-type pipe? Next, follow the editor to take a look and understand these contents together.

1. HDPE reinforced winding pipe type B is wound and formed in the hot melt state, the product is uniform as a whole, and there is no place for welding.

2. The heat storage of the product in the molding is completely dissipated, and the internal stress will not be formed, resulting in the delamination and cracking of the HDPE reinforced winding pipe B-type pipe.

3. The use of cold demoulding, after cooling the pipe to room temperature, and then using the mold shrinkage to demold, will not make the product deformed. If the square tube is extruded first, wound into a round tube

by cold water shaping, and then cooled with water, the following situations are likely to occur:

(1) There are obvious welded parts, and the quality of the product is difficult to control and guarantee.

(2) The use of water to quickly cool down, the heat is dissipated unevenly, and the spring cracking is easy to occur if the control is not good.

(3) There will be problems in the connection between the joint and the pipeline and the inspection well, resulting in water leakage.

Compared with the HDPE reinforced spiral wound pipe B-type pipe of the same material and the HDPE central control wall pipe (A-type pipe), the B-shaped pipe is better than the A-shaped pipe in terms of technology and application. Under the same index, the materials of A-shaped pipe and B-shaped pipe are about the same, and the price is not much different, so in general, B-shaped pipe is better than A-shaped pipe in general.

The above is all the content of the characteristics of HDPE reinforced winding pipe B-type pipe shared with you, I hope to help friends who see this article.
