PVC pipe sizes in mm and inches

PVC pipe, or polyvinyl chloride pipe, is a pipe material widely used in construction, drainage, wire protection and other fields. Due to its excellent performance and wide application fields, the size of PVC pipe is also particularly important. This article will introduce in detail the correspondence between the two units of PVC pipe sizes in mm and inches.

PVC pipe sizes in mm and inches

The size of PVC pipes is usually marked in nominal diameter (DN) or inches. Among them, the DN unit is often used to identify water pipes and drain pipes, while the inch unit is more common in wire pipes and pipes in certain specific fields. Regardless of the unit, the size of PVC pipes is closely related to its application scenario.

In the millimeter unit, the size of PVC pipes ranges from as small as 10mm wire pipes to as large as hundreds of millimeters of drain pipes. Common household PVC water pipe sizes include 16mm, 20mm, 25mm, 32mm, 40mm, 50mm, etc. These sizes of water pipes are usually used in household water supply systems. The size of the drain pipe is relatively large, and the common ones are DN32, DN40, DN50, DN75, DN110, etc. These sizes of pipes are usually used to discharge domestic sewage. For the industrial field, the size of the drain pipe may be larger, such as DN200, DN250, DN400, etc., to meet the discharge needs of large-volume sewage.

In the inch unit, the size of PVC pipes is also rich and varied. Common inch unit markings include 1/2 inch PVC pipe, 3/4 inch PVC pipe, 1 in PVC pipe, 1-1/4 inch PVC pipe, 1-1/2 inch PVC pipe, 2 inch PVC pipe, 5 inch PVC pipe, 10 inch PVC pipe, 12 inch PVC pipe, etc. These pipes of different sizes are usually used for wire protection and fluid transmission in specific fields. For example, 1/2-inch PVC wire pipe is often used for indoor wiring, while a 2-inch PVC pipe may be used to transport liquids or gases. It is worth noting that the size of PVC pipes in inches is usually based on the actual outer diameter, not the inner diameter. For example, the actual outer diameter of a 1/2-inch PVC pipe is usually 0.84 inches (about 21.34 mm), not exactly 0.5 inches.

In addition to the common sizes mentioned above, PVC pipes can also be customized according to customer needs. Whether it is in millimeters or inches, as long as the customer provides specific size requirements, the Puhui Industry can usually produce PVC pipes that meet the requirements. This flexibility allows PVC pipes to be widely used in various fields and scenarios.

Parameters you need to know when choosing PVC pipes

When choosing PVC pipes, in addition to considering the size, you also need to pay attention to parameters such as material, wall thickness, and pressure rating. These factors will directly affect the performance and life of PVC pipes. Therefore, when choosing PVC pipes, it is recommended to consult professionals or manufacturers for accurate advice and guidance.

In short, PVC pipe sizes are one of the key factors in its application performance and applicable scenarios. By understanding the corresponding relationship between millimeters and inches of PVC pipes and the application scenarios of various sizes, we can better select and use PVC pipes to meet various needs.
