Final answer:
Welded fittings are necessary in industrial plants because they provide reliable and leak-proof connections between pipes and equipment. They offer advantages such as increased safety and improved performance.
Step-by-step explanation:
Welded fittings are a necessity in industrial plants because they provide reliable and leak-proof connections between pipes and other equipment. The welding process creates a strong bond between the fittings and the pipes, ensuring that they can withstand high pressures and temperatures present in industrial applications.
One example of a welded fitting commonly used in industrial plants is the butt weld fitting. This type of fitting is welded directly to the pipe end, creating a smooth and seamless connection. Another example is the socket weld fitting, which is welded to the pipe using a socket that provides additional strength and durability.
Overall, welded fittings offer several advantages in industrial plants, including increased safety, improved performance, and reduced maintenance requirements.
