Joining Methods

Joining methods refer to both the methods and materials used to combine piping materials for specific applications.  All joining methods must first and foremost provide secure, dependable, and verifiable means of combining or joining pipe or tubing materials.  For any given material, there may be multiple accepted joining methods. Many joining methods are proprietary to a given manufacturer of joining materials or products. These products may have different value characteristics, such ease of installation or advanced means of verifying a quality coupling, and quality vendors should be sought to provide these products and sound advice for specification or installation. Some joining methods are specific to a piping product, such as PEX or CSST, and are therefore listed by material rather than by method.
