The main points of installation of plastic pipes are as follows:
Water pressure test
Plastic pipes are lightly installed, bendable, easy to connect, and easy to cut. They are often installed by non-professional operators. However, they are often only tested for water flow after installation. Water pressure tests are rarely performed. Once the water pressure in the urban water supply network fluctuates, It is easy to cause water leakage. Nowadays, many room decoration often chooses the concealed water pipes, but if the concealed water pipes are not subjected to the hydrostatic test, the hidden danger is even greater. The leakage needs to destroy the surface of the wall to be repaired.
To do expansion compensation
The expansion coefficient of plastic pipes is larger than that of steel pipes, and sufficient compensation margin is required for conveying hot water. Engineering users often consider the design of drawings, and it is not easy to cause problems. However, users of room decoration often have water leakage incidents caused by expansion.
Antifreeze measures
Insulation protection of water supply pipelines has been deeply rooted in the people's heartland in China, and it is also highly valued. Most of the current phenomenon of freezing and water leakage is in Anhui, Jiangsu, Zhejiang and other provinces in East China. These places belong to non-heating areas in winter and generally do not end. Ice, but if you encounter the freezing of a decade, you often freeze the water pipe because of the missing insulation measures.
Metal sheet & tube Laser Cutting Machine available for metal plate and tube cutting in various materials such as stainless steel, carbon steel, alloy steel, spring steel, copper, aluminum, gold, sliver, titanium etc.
Metal sheet & tube laser Cutting Machine advantage:
1. Auto - focus
Applicable to various focal lengths, which are controlled by machine tool control system. Focal point will be automatically adjusted in cutting process to achieve the best cutting effect of different thicknesses sheets metal.
2. Free
Focal length is controlled by operating system. We don`t need to do manual regulation, which effectively avoids errors or faults caused by manual operation.
3. Fast
Auto focus would automatically adjust the most appropriate focal points in the process of punching and cutting, which greatly improves cutting speed;
4. Accuracy
Metal sheet & tube laser cutting machine with increasing perforation focus length, separately setting perforation focal length and cutting focal length, enhance cutting accuracy.
