PVC plastic hose is a common pipe material in life and industry. What are the PVC plastic hoses that are named differently according to different pressures? Let's take a look together.
Single-layer PVC plastic hoses are called fluid pipes, horizontal pipes or gravity pipes. The pressure they bear is very low, generally around 0.5 kg to 1.5 kg, and the color is mostly transparent.
The one with slightly higher pressure resistance is the ordinary two-glue one-line hose. This is called a PVC fiber hose. A layer of fiber is added between the outer layer and the inner wall layer, which can reach about 3-6 kg. This kind of hose can meet most of the requirements. Usage.
The ones with higher pressure resistance are three-glue first-line or three-glue two-line pipes. They have three layers of PVC hoses and add 1-2 layers of fiber. According to different pressure requirements, the materials of the three layers will be slightly different. the difference. The higher one is the high-pressure pipe, which generally requires a very high pressure above 1MPA or even above 1.5MPA. This kind of material is different regardless of the wall thickness or the middle layer.
