What is Tongue And Groove Flange? Dimensions, Properties and Uses
Tongue and groove flange is a type of piping flange widely used in the piping industry for connecting pipes and other components. With its unique and precise design, tongue and groove flanges are preferred for various applications in gas, oil, chemical, and other process industries. This blog post will explore what tongue and groove flange is, its dimensions, properties, and uses.
What is Tongue and Groove Flanges?
Tongue and Groove flanges are two separate parts that are connected. The “tongue” is a raised, bevelled edge on the flange face that fits into an indented groove or “valley” on the mating flange or fitting. This connection type provides great performance in high-pressure applications up to 1,500 PSI and excellent sealing capability. In addition, it allows for easy installation and dismantling of piping systems without any welding or special tools. The tongue-and-groove joint has been used by engineers for centuries in timber construction to provide a strong interlocking connection between components.
