![]() ![]() CPVC also can be used as vent piping when necessary, but only when venting air temperatures that are less than 200 degrees. These pipes are often used to replace copper or cast iron, and can serve many of the same purposes. For that reason, CPVC is mostly used in plumbing applications at places like factories where chemical and heat resistance matter, while manufacturers use PVC in many kinds of consumer goods.ĬPVC is used to create commercial- or industrial-grade pipes for liquid distribution as well as the fittings to secure them. For the most part, CPVC is used in plumbing products.īoth CPVC and PVC are capable of many of the same tasks, but CPVC is much more expensive. Its flexibility also makes this product impact-resistant, further improving its durability. This flexibility makes it easy to work with, and there is a bit of give when encountering joints that aren’t perfectly aligned. This makes it useful in commercial and industrial settings, where chemicals and high temperatures are more likely to be present.ĬPVC also is more flexible than cast iron or copper pipe. The manufacturing process makes CPVC resistant to chemicals and degradation, allowing it to last a long time. While both are strong, impact-resistant, and somewhat flexible, CPVC excels at each of these characteristics. It’s safe to consider CPVC as a superior material to PVC. CPVC is chemical-resistant, flexible, and strong. Not only is CPVC better suited for chemical applications, the solvents and primers used to bond these materials are different. However, CPVC has a maximum operating temperature of 200 degrees before it softens.Īlso, CPVC and PVC react to chemicals differently. Beyond that temperature, the plastic softens and loses its shape, which can lead to leaks. PVC’s maximum operating temperature is 140 degrees. The chemical makeup of CPVC makes it far more resistant to corrosion and degradation over time than PVC, but it’s also better suited for higher temperature applications. While it’s true that the names are similar, and the two products even look similar, there are some significant differences between CPVC and PVC. CPVC and PVC are both plastics, but CPVC is more durable and longer-lasting. However, both PVC and CPVC are popular plumbing pipe compounds, but they’re not exactly interchangeable. Without an in-depth chemistry lesson, this allows CPVC to be more resistant to degradation and improves its lifespan. If that seems redundant, there’s a reason: the manufacturing process further chlorinates the plastic and changes its chemical composition. The plumb bob confirms amount of moment and direction, easily, since 5 years ago.“CPVC” stands for chlorinated polyvinyl chloride. Here is a picture of me checking my shed for movement after 5 years of ground shifting hot summers and freezing winters. I use mine to mark whole lengths of studding inside finished walls when hanging stuff like cupboards and shelves, verifying vertical runs of pipe, setting picture frames, checking walls and door frames, etc, etc. A plumb bob has been used for centuries, it was a must-have tool for ancient Egyptian architects when they were building their pyramids. Foundation and Excavation contractors mostly rely upon the plumb bob and building a chimney the tool will be indicating whether a flue is veering off plumb or. Surveyors use plumb bobs sometimes for transferring points or lining them up. Once it is suspended, thanks to the laws of gravity, a vertical line is created. In one place, the plumb bob can be used to sight an object in some other pipe, for example for plumb. The working principle of a plumb bob tool is simple. Laser beams can diffuse apart over distance, but the plumb line remains true from one end to another. Plumb bobs are made of various materials, including brass, steel, etc. And of course they can sit in place all day while you build that perfect tall wall. If used with a protractor (or even a carpenters speed square) degrees can be measured. They can provide a line of 'marks' very quickly across great lengths when levels and lasers fail or not practical to use. Plumb bobs and their lines, can convey a sense of 3D alignment very quickly, in some cases when levels and lasers can't. Yet plumb bobs never need batteries, never need to be calibrated, and are foolproof except perhaps in strong wind. ![]() ![]() Plumb bobs need a little time to 'settle' and many people simply don't have time or patience, thus they have fallen out of favor with the speed and ease of use of spirit levels and laser. ![]()
