Article Introduction
Finding the PVC pipe with the right specifications for the job is often difficult when having to compare measurements between many pipe products. To streamline this process and make it easy to find the right pipe, PVC Pipe Supplies has compiled PVC pipe specifications for size, wall thickness, inner diameter, outer diameter and average pipe weight for both schedule 40 and schedule 80 plumbing. Sizes listed below are in NPS (Nominal Pipe Size) sizing standard.
Different sizes between different PVC pipes
1. PVC rigid tubing
PVC rigid tubing is measured and listed by the actual dimensions of the inside and outside diameter measured. For instance: 1/2” rigid PVC tubing is 1/2” outside diameter and 3/8” inside diameter. The fittings that can be used for this type of tubing are compression fittings or flexible fittings that can be clamped onto the PVC tube.
2.PVC flexible tubing
PVC flexible tubing is measured and listed in the same way as the rigid tubing; you would measure the outside and inside diameters. The difference is the type of fittings that you would use. Hose barbs or insert fittings should be used, and they get inserted into the tubing. That is why you would go by the inside diameter of the tubing to determine the size fitting you need.
For instance: 1/2” outside diameter tubing with a 3/8” inside diameter would require a 3/8” hose barb or insert fitting.
3.PVC pipe
PVC pipe sizes are nominal, so the pipe is neither the outside nor the inside diameter for most pipe sizes. PVC pipe is socket fittings (schedule 40) and socket or threaded fittings (schedule 80). All socket fittings are designed to go on the outside of the pipe, not the inside.
Schedule 40 PVC Pipe Specifications
1. PVC pipe specifications are usually expressed in nominal outer diameters. No. 40 PVC pipes refer to pipes with an outer diameter of 40 mm.
2. In addition to the outer diameter, PVC pipes have other specifications, such as length, pressure level, etc. However, for No. 40 PVC pipes, the main focus is on its outer diameter.
3. In practical applications, 40mm PVC pipes are often used in drainage, water supply and other systems, and have a wide range of applications.
4. It should be noted that PVC pipes produced by different manufacturers may have certain size differences, so when choosing, the specific specifications and sizes should be confirmed with the manufacturer providing the pipe.
In summary, the outer diameter of No. 40 PVC pipes is 40mm, which is one of the common pipe specifications.
Schedule 80 PVC Pipe Specifications
PVC pipe No. 80 usually refers to the DN80 specification. Its outer diameter is not strictly equal to 80mm, but is close to or slightly larger than this value. The specific size may vary depending on different standards and manufacturers.
In the PVC pipe system, DN (nominal diameter) is a commonly used specification representation method. It represents certain dimensions of the pipe system components, but not the actual outer diameter of the pipe. For DN80 PVC pipes, the actual outer diameter may vary due to different pipe wall thickness, pressure level, and production standards (such as national standards, American standards, etc.). For example, in some cases, the outer diameter of DN80 PVC pipes may be close to or slightly larger than 90mm.
However, it should also be noted that not all PVC pipes strictly follow this rule. In particular, the specifications and sizes of PVC pipes may vary in different applications and regions. Therefore, when selecting and purchasing DN80 PVC pipe fittings, it is best to directly refer to the manufacturer’s product specification sheet or consult professionals to ensure that the selected pipe meets the specific application requirements.
In addition, PVC pipes have other specification parameters, such as wall thickness, length, connection method, etc., which will also affect the performance and use of the pipe. Therefore, when selecting DN80 PVC pipe fittings, in addition to paying attention to its outer diameter specifications, other factors need to be considered comprehensively to ensure that the selected pipes can meet the specific application requirements.
Conclusion
In summary, the size and weight of PVC pipes vary depending on many factors. When choosing PVC pipes, in addition to considering size and weight, you also need to consider the specific application requirements and scenarios. For example, in building water supply and drainage systems, the diameter and wall thickness of the pipes need to be determined based on factors such as water flow and pressure; in electrical engineering, you need to choose appropriate electrical conduits to protect wires and cables, etc.
