The downpipe profile is used to collect rainwater on the roof, which is a component of the downwater system and is concentrated to the rainwater pipe laid below the ground. Downpipe profiles can be divided into: 1. Metal pipes (such as cast iron pipes, color aluminum pipes, copper pipes, etc.); 2. Plastic pipes (such as PVC pipes, etc.). Among the many downpipe profiles, which one is better?

PVC pipe is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC averaged 1.4 million tons. Some specific introductions to PVC pipes.

Profile pipe: It is an object with a certain geometric shape made by rolling, extrusion, casting and other processes of iron or steel and materials with certain strength and toughness (such as plastic, aluminum, glass fiber, etc.), and its uniform length is 6m . Profile pipes refer to materials manufactured in accordance with certain standards and using man-made materials for standardized and large-scale production. The profile pipe has a certain appearance size, a certain shape in section, and certain mechanical and physical properties. Profile pipes can be used alone or further processed into other manufactured products, often used in building structures, manufacturing and installation.So what is the extrusion principle of the profile pipe?

Spiral wound pipe, large-diameter wound pipe, double-wall wound pipe, hollow wound pipe is a kind of high-density polyethylene (HDPE) as raw material, a kind of pipe formed by wound and welding, due to its unique molding process, can produce up to diameter 3 meters of pipe, which is difficult to complete with other production processes. High-density polyethylene (HDPE) not only guarantees the product molding process and product quality due to its excellent welding performance, but also provides a variety of reliable methods for construction connection, such as electric heating welding, heat shrinking connection, etc., at the same time, this It is also an important reason why leakage rarely occurs. It is precisely for this reason that this spiral wound pipe has unique environmental protection functions that other pipes do not have. This provides a very effective method for pollution prevention and control that people are currently concerned about. So What are the advantages and disadvan
