What type of joint is commonly used for PVC pipe connections?

The type of joint commonly used for PVC pipe connections is known as a solvent weld joint. This method involves using a solvent cement that chemically fuses the PVC materials together. When applied, the solvent softens the surfaces of the pipes and fittings, allowing them to bond at a molecular level, creating a secure and watertight seal.

This is particularly advantageous for PVC piping because it ensures a seamless connection that minimizes leakage and maintains the structural integrity of the piping system. Solvent welding is widely used due to its effectiveness in various applications, including residential plumbing and industrial installations.

In contrast, welded joints typically refer to metal pipes where high heat is applied to create a bond, which is not applicable for PVC. Screwed joints involve threaded connections, which are better suited for certain types of metal fittings rather than plastic pipes. Saddle joints are used to connect a smaller pipe to a larger pipe without cutting into the main line, but they are not as commonly used as solvent welds for securing PVC pipes.
