There are many different diameters of PVC pipe. some are large on the outside for example 12 inches and Some are little, at 1/2". The difficulty is that what the industry labels a 1" pipe is not exactly 1" in diameter. Because of this complicated situation, many of our customers question us, "What is the outside diameter of PVC pipe?" If you have the same question, it can be answered by the chart below. Keep reading to see why the outer diameter, or "OD" of PVC pipe is not the same as what the name suggests. What is the OD of PVC Pipe? The outside diameter of PVC pipe is actually slightly greater than what its name suggests. This is because PVC pipe and fittings use a nominal system. That means that compatible parts are given the same designation, so all 1" pipe will fit in 1" fittings and so on. 
The measurements in pipe names are the PVC nominal pipe diameters, but not how necessarily how long they measure across. This is a difficult concept, but the aim of this nominal system is to make picking the proper parts easier. PVC Pipe OD Chart The PVC pipe OD chart below shows the nominal size of the PVC pipe on the left together with the actual OD on the right. As discussed earlier, the OD for schedule 40 and schedule 80 PVC pipe are always the same. How to Determine the External Diameter of a PVC Pipe Consider the end of a length of PVC pipe. Determine the widest part of the opening. Measure from one pipe's outer edge to the other pipe's outer edge. This measurement represents the pipe's outer diameter or "OD."

PVC Pipe Sizes and Dimensions The "ID," which stands for the internal diameter of schedule 40 pipe, is used to describe the size of PVC pipe. What exactly does this entail? This indicates that the size of a standard Schedule 40 PVC pipe is determined by the measurement of the 'hole' contained within the PVC pipe. The PVC industry utilizes this method. This is the measurement taken from the very top to the very bottom of the PVC pipe's interior. All too frequently, individuals will measure the Outside Diameter (OD) of their PVC pipe, and then use this measurement to determine the size of their PVC pipe. Because of this mistake, they end up buying a size that is significantly larger than what is necessary for their pipe. The following is the most effective method for determining the diameter of the PVC pipe that you possess: Examine the marks left by the manufacturer on the side of the pipe. Take the OD and ID measurements, then check them against the chart below. If you bought your PVC pipe from a hardware store, the markings on the side of the pipe can be used to determine what size pipe you have. Near the location where the manufacturer's name is printed, it will typically show the size in decimal or fraction form, such as "1.25" (which stands for 1-1/4 inches) or "3/4" (which obviously stands for 3/4 inches). When placing an order for PVC fittings or accessories, use this measurement as the standard. You can determine the size of the PVC pipe you have by measuring both its inside and its outside diameters, which are denoted by the acronyms OD and ID respectively. To determine the size of your PVC pipe, use the table below.

Even at a lower pressure than the rating of PVC pipes, there have been reports of large diameter UPVC pipes failing during commissioning or usage all over the world. These failures occurred at a lower pressure than the rating of PVC pipes. This occurs with the pipes that have been appropriately examined and accepted in accordance with the standard that is in effect, not only by the manufacturer but also by the third party authorities. The manufacturers are unable to pinpoint the precise cause and are under the impression that it is not their responsibility. They say that the failure was due to the customer's improper handling, incorrect installation, failure to provide adequate vents, or improper commissioning process, among other things. When this happens, the manufacturer usually has to replace the pipeline, which results in significant losses for the company, both financially and in terms of its reputation. It has been determined that a process known as Rapid Crack Propagation is to blame for this issue (RCP). RCP is an abbreviation that stands for "rapid crack propagation," which describes the collapse of a pipe in which a fracture spreads very quickly for a distance of many feet or perhaps hundreds of feet. A "rapid brittle fracture" or a "linear split" are two other names for this type of break. It is common knowledge that RCP can be found in pipes made of metal, such as ductile iron and cast iron, but this substance can also be found in PVC pipes. 
outside diameter of pvc pipe
PVC pipe with different outside diameter is utilized for a wide range of applications, including water mains, irrigation, and sewage pipes, to name a few. PVC pipes can be found in different sites throughout the world. They are simple to install, durable, long-lasting, affordable, lightweight, and environmentally beneficial. In addition, they possess enduring properties. Before using PVC pipe, it is crucial to understand its varied sizes and dimensions. Pipes composed of PVC are measured using the nominal system. 
This means that instead of focusing on individual measurements, all computations are based on the many types of structures. For example, a pipe with a length from one end to the other of 0.84 inches is regarded to be one inch. PVC Pipes are ordered according to one of three schedules: schedule 40, schedule 80, and schedule 120. To avoid cost overruns, abuse, plumbing troubles, and delays in the project, it is vital and advantageous for you to perform extensive research and choose the product that best meets your requirements.
