Head (reducer) is a kind of pipe fitting used for pipe diameter. Usually, the forming process is reduced-diameter pressing, expanded-diameter pressing or reduced-diameter plus expanded-diameter pressing, and some specifications of reducing pipes can also be formed by stamping.

The use of pvc casing is a protective measure to prevent the root of the pipe from being damaged by external forces. (Plastic pipes are afraid of destruction from the root, because maintenance is very difficult).
2. Convenient installation and maintenance of pipelines
Pipeline installation, the operator's space utilization range is large, can be used freely. The operator has very limited space for maintenance after the user has moved in, and replacement of pipes (up to the service life, etc.). The pipe can only be temporarily fixed with pipe supports and sleeves for corresponding operations. At the same time, the setting of pvc sleeve can also avoid the breakage of the indoor decoration when the pipe is replaced. If the pvc sleeve is not installed, when the above operation is carried out, the pipe will cross the wall, resulting in wall damage.
3. The sleeve of the water room has the function of preventing water seepage, flow and drip to the lower layer
Prevention has two aspects, on the one hand, refers to after the completion of the project, the user in the decoration stage, improper reasons, resulting in the flow of tap water, down through the casing layer; On the other hand, after the user enters, the accident causes the tap water flowing through the casing down the layer. And the former often outnumber the latter.
Light weight, low price, easy to transport, install, protect and maintain. It has the advantages of high impact strength, high mechanical performance, good toughness and flexural strength, which reduces the crushing problem in construction and application. It is especially suitable for drainage pipelines of airports, highways and railways. Beautiful appearance, lubrication of inner wall, small friction coefficient, anti-corrosion, abrasion resistance and no scaling of inner wall of pipeline, reduce friction resistance of fluid, improve efficiency of fluid transportation and reduce noise.
PVC drain pipe sanitary grade PVC resin is the main raw material, adding appropriate stabilizer, lubricant, filler, carbon powder and other plastic extruder extrusion and injection molding machine, through cooling, curing, formation, inspection, packaging and other procedures to complete the production of pipes and fittings. PVC drainage pipe has high safety factor, low friction coefficient, smooth flow, not easy to plug, less protection work, good water tightness, good aging resistance, normal service life of more than 50 years, excellent corrosion resistance to inorganic acid, alkali and salt.
It has the advantages of high impact strength, high mechanical performance, good toughness and flexural strength, which reduces the crushing problem in construction and application. It is especially suitable for drainage pipelines of airports, highways and railways. The application of temperature scale is large, weather resistance is outstanding, and the stability of temperature scale is good when temperature changes.
1. Light pipes and convenient construction 2. Good drainage performance. A smaller slope is used to increase the clear height of the space and enhance the use function of the building. 3. Economical and beautiful. There is no corrosion and peeling of the outer wall of cast iron pipe, which can improve people's living and working environment and facilitate the property management of buildings. 4. Good social benefits can greatly reduce energy consumption in steelmaking process. 5. The physical and chemical temperature of PVC drainage pipe has the advantages of strong corrosion resistance, aging resistance, wear resistance and long service life.
