Standard PVC pipe sizes mainly include diameter, wall thickness and length, with various specific specifications suitable for different application scenarios. Common specifications include 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 180mm, 200mm, 250mm, 315mm, 400mm, 500mm, 630mm, etc. These specifications cover PVC pipes from small diameter to large diameter, meeting different application requirements.
Standard pvc pipe sizes
Diameter: The diameter of PVC pipes is usually expressed in millimeters, and common diameters range widely, including but not limited to 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, 75mm, 90mm, 110mm, 125mm, 140mm, 160mm, 200mm, 250mm, 315mm, etc. The larger the diameter, the stronger the pipe’s carrying capacity, and it is suitable for conveying media with larger flow rates.
Wall thickness: The wall thickness of the PVC pipe is also an important factor affecting its carrying capacity. Common wall thicknesses are 1.5mm, 2.0mm, 2.3mm, 2.5mm, 3.0mm, 3.2mm, 4.0mm, etc. The thicker the wall, the stronger the pipe’s carrying capacity, but the cost will also increase accordingly.
Length: The length of the PVC pipe is usually 4 meters or 6 meters, and there are also some special specifications of pipes with a length of 3 meters or 5 meters. The choice of length should be determined according to the specific use occasion and needs.
PVC pipe application
PVC pipes are widely used in water supply, drainage, electrical line protection, agricultural irrigation, and other fields due to their excellent physical and chemical properties. Different fields have different requirements for the specifications of PVC pipes. Therefore, when selecting PVC pipes, it is necessary to determine the appropriate diameter, wall thickness, and length according to the specific usage scenarios and needs. For example,
1. Common specifications of PVC Pipes for Water include diameters ranging from 20mm to 400mm, wall thicknesses of 2.3mm, 3.2mm, 4mm, 5mm, and other options, and lengths of 4 meters or 6 meters. They are mainly used in water supply systems such as urban water supply networks and farmland irrigation, etc.
2. Common specifications of PVC Drainage Pipes include diameters ranging from 40mm to 400mm, wall thicknesses of 2mm, 3.2mm, 4mm, and other options, and lengths of 4 meters or 6 meters. They are mainly used in drainage systems such as municipal engineering and building sewage discharge. Choosing the right PVC pipe specifications is crucial to ensuring the safety and efficiency of the system.
3. When used as a threading pipe, the commonly used sizes are 16mm, 20mm, 25mm, 30mm, 40mm, 50mm, etc.
PVC pipe performance category
PVC pipes can be divided into soft PVC pipes and hard PVC pipes according to their performance. The main difference is whether plasticizers are added. Because soft PVC pipes contain plasticizers, their physical properties are relatively weak and they can withstand lower water pressure. Hard PVC pipes do not contain plasticizers, have stronger physical properties, and are suitable for applications that require higher strength and water pressure.
Advantages
1. Corrosion resistance: PVC pipes have very good corrosion resistance to inorganic acids, alkalis, salts and other substances, and are suitable for industrial wastewater discharge and transportation.
2. Durability: The normal service life can reach more than 50 years, the pipeline friction coefficient is small, the water flow is smooth, it is not easy to clog, and the maintenance workload is small.
3. Safety: The material has a high oxygen index and is self-extinguishing. The linear expansion coefficient of the pipeline is small, the deformation affected by temperature is small, the thermal conductivity and elastic modulus are small, and the anti-freezing performance is excellent compared with cast iron drainage pipes.
4. Construction convenience: The connection of pipes and fittings can be bonded, the construction method is simple, the operation is convenient, the installation efficiency is high, and it has good water tightness.
