12 inch PVC pipe is mainly used in industry and large-scale construction projects to meet higher water supply and drainage needs. PVC pipe is widely used in various fields due to its excellent performance characteristics. For 12 inch PVC pipe, its larger size enables it to meet the high water supply and drainage needs of industry and large-scale construction projects. PVC pipes of this size are often used in water supply and drainage systems of industry and large-scale construction projects, ensuring efficient water flow transmission and processing capabilities, and are suitable for situations where large amounts of water flow need to be processed. In addition, due to its corrosion resistance and heat resistance, 12 inch PVC pipe is also suitable for applications in some special environments, such as chemical engineering and other high-demand occasions
Definition Use
12 inch PVC pipe refers to a pipe with a diameter of 12 inches, which is about 304.8 mm. This pipe is widely used in my country’s oil, natural gas, water supply and drainage, chemical industry, and other fields. PVC pipes are widely used in various industrial and civil fields due to their corrosion resistance, durability, and cost-effectiveness. PVC pipes have various specifications, and different diameters and thicknesses can be selected according to specific application requirements. In addition, the use of PVC pipes is also favored due to their good plasticity and processability and ability to adapt to various complex pipeline layouts and connection requirements.
Production process
1. Raw material preparation: The main raw materials of PVC pipes are polyvinyl chloride (PVC) resin, as well as various additives such as stabilizers, plasticizers, fillers, etc. These raw materials need to be accurately weighed according to the formula ratio.
2. Mixing: Put the weighed raw materials into the mixer for mixing to ensure that the various components are evenly distributed.
3. Melt extrusion: The mixed materials enter the extruder, melt into liquid under high temperature and pressure, and then extrude through the mold to form the pipe prototype.
4. Cooling and shaping: The extruded pipe prototype is cooled by the cooling water tank to harden and shape it.
5. Cutting: The shaped pipe is cut according to the required length.
6. Secondary processing: If necessary, secondary processing such as inner and outer wall grinding and printing logos can be carried out.
7. Inspection and packaging: Finally, the finished product is inspected for quality, and after passing the inspection, it is packaged and ready for shipment.
PVC pipe basic formula table
The following is a basic PVC pipe formula table. The specific formula may vary depending on the manufacturer and product requirements:
-PVC resin: 100 parts
Stabilizer: 2-5 parts (commonly used are lead salts, calcium zinc composite stabilizers, etc.) Plasticizer: 10-30 parts (such as DOP, DBP, etc.)
Filler: 20-50 parts (such as calcium carbonate, talcum powder, etc.)
Lubricant: 0.5-2 parts (such as stearic acid, paraffin, etc.) Processing aids: 0.1-1 parts (such as antioxidants, ultraviolet absorbers, etc.)
The amount in the above formula is usually based on the weight of the resin, and the unit is usually “parts”
Please note that in actual production, the formula and process parameters need to be adjusted according to factors such as equipment performance, product requirements, and environmental conditions. At the same time, in order to ensure product quality and environmental protection requirements, it is also very important to choose non-toxic and environmentally friendly additives.
