What type of joint involves a compression joint with a conical spread made on the end of a tube?

A flared joint involves the creation of a conical spread at the end of a tube, allowing the tube to fit snugly against a corresponding fitting. This design facilitates a secure connection, as the flared end increases the surface area that contacts the fitting, enhancing the joint's strength and integrity. Flared joints are commonly used in plumbing and gas connections to create a solid, leak-resistant seal that can withstand pressure.

In contrast to other types of joints, a flared joint is specifically characterized by its conical shape, which distinguishes it from welded, compression, or interlocking joints. Welded joints rely on melting and fusing materials together, while compression joints use a mechanical force to seal the connection without altering the shape of the pipes or fittings. Interlocking joints involve physically fitting parts together in a manner that locks them, but do not utilize the distinct conical spread feature found in flared joints. This unique configuration of the flared joint is critical for applications requiring reliability in high-pressure environments.
