Threaded Flanges
Threaded flanges, similar in outline to slip-on flanges, feature a threaded bore for assembly without welding, making them suitable for low-pressure piping systems. Optional welding after assembly is not recommended for enhancing performance.
These flanges are cost-effective and easy to install, widely used in industries like plumbing, water treatment, and low-pressure gas systems where welding is impractical or unnecessary.
Threaded flanges are designed for low-pressure applications, featuring a threaded bore that allows the flange to be screwed onto a pipe without welding. This simplifies installation and reduces costs, particularly in systems where welding equipment is unavailable or hazardous. While a seal weld around the joint can be applied post-assembly, it is not considered a reliable method for increasing the flange’s pressure capacity, limiting their use to less demanding environments.
Threaded flanges are manufactured to meet industry standards, ensuring compatibility and performance in low-pressure piping systems.
