Product Description Product Description1. By Material Hardness (The Most Basic Classification)Rigid PVC Pipe (UPVC Pipe)Full name: "Unplasticized PVC Pipe" (UPVC Pipe). It contains no or minimal plasticizers and boasts high hardness, strength, resistance to aging, and corrosion (acids and alkalis, etc.). It is the most commonly used type of PVC pipe.Applications: Building water supply and drainage, municipal sewage disposal, electrical wiring, agricultural irrigation, and industrial transportation (non-high-temperature media).Soft PVC Pipe (SPVC Pipe)Full name: "Plasticized PVC Pipe" (SPVC Pipe). It contains a high concentration of plasticizers (such as phthalates). It offers excellent flexibility, bendability, and sealing properties, but its temperature resistance and strength are lower than rigid PVC pipe.Applications: Household hoses (such as showerheads and drainpipes), cable protectors, medical device hoses, and small fluid transport (non-high-pressure applications). 2. By Application (Most practical, strongly relevant to the scenario)Construction and Civil UsePVC Water Supply Pipe: Used for cold water transportation within buildings (must comply with drinking water safety standards, such as GB/T 10002.1), with high pressure resistance (commonly 1.0 MPa and 1.6 MPa).PVC Drain Pipe: Used for indoor drainage (domestic sewage and rainwater) in buildings. Available in vertical and horizontal configurations, it prioritizes drainage flow and has a lower pressure resistance.PVC Rainwater Pipe: Designed for collecting and discharging rainwater from building roofs or exterior walls. Mostly surface-mounted, it has a larger diameter (such as DN75 and DN110).PVC Conduit (Electrical Conduit): Used for protecting building electrical wiring (both high and low voltage). It must be flame-retardant and insulate (such as GB/T 16806). Available in light, medium, and heavy duty. Municipal and EngineeringPVC Sewage Pipe: Used for transporting municipal and industrial wastewater. These are typically large-diameter rigid PVC pipes, with double-wall corrugated pipes being common (for impact resistance and high drainage capacity).PVC Irrigation Pipe: Used for agricultural or garden irrigation. These pipes offer strong weather resistance (UV resistance) and can be buried or surface-mounted. Diameters can be customized (e.g., DN50-DN300).PVC Ventilation Pipe: Used for building ventilation and exhaust (e.g., kitchen exhaust and basement ventilation). These pipes require lightweight construction and wind pressure resistance.Industrial and SpecialtyPVC Chemical Pipe: Transports corrosive media (acids, alkalis, and salt solutions). These pipes are characterized by high purity and chemical resistance.PVC Cable Protection Pipe: Protects underground cables (e.g., power and telecommunications cables). These pipes are pressure-resistant and corrosion-resistant, often used as rigid pipes for underground use.PVC Food-Grade Hoses: Transport fluids that come into contact with food (e.g., beverages and sauces). These hoses must comply with food contact safety standards (e.g., GB 4806.7). These pipes are typically made of soft PVC.,By Structural FormOrdinary straight pipe: The most common cylindrical straight pipe, with either plain ends or sockets (for easy connection), is widely used in water supply, drainage, and wiring.Corrugated pipe: The pipe wall is corrugated (inner and outer wall corrugations or double-wall corrugations), offering excellent flexibility, light weight, and pressure and impact resistance. It is divided into single-wall corrugated pipe (small diameter) and double-wall corrugated pipe (large diameter, used for mainstream municipal sewage treatment).Spiral pipe: The inner or outer wall has a spiral structure to enhance rigidity or optimize drainage resistance (such as spiral noise reduction drainage pipe, which reduces water flow noise).Composite pipe: PVC is composited with other materials (such as PVC-U/PE composites and PVC-wire mesh composites) to enhance pressure and impact resistance. It is used for high-pressure water supply or complex environments.4. By SpecificationsPipe Diameter: Nominal Diameter (DN, such as DN15, DN20, DN50, DN110, DN200), Outside Diameter (De, such as De20, De25, commonly used in plastic pipe markings). Wall Thickness and Pressure Rating: These pipes are categorized by pressure, such as S5 (1.0MPa), S4 (1.6MPa), and S3.2 (2.0MPa). The higher the pressure rating, the thicker the wall thickness, making them suitable for high-pressure applications (such as water pipes).Length: Common lengths are 4 meters and 6 meters per pipe, but custom lengths and cutoffs are also available.
