What are the types of flanges?

Answer 1

RING TYPE JOINT FLANGE

The ring type joint flange metal is used for leak proof process. It is a part of steel. Sometimes the pressure becomes high at that time the ring type joint flange is using. A metal ring is compressed like a seal helps to high-pressure leak proof.

THREADED RING FLANGE

In threaded ring flange welding is not needed. It is threaded or screwed into another. It is used in low pressure and it can connect only with other threaded material.

LAP JOINT RING FLANGE

Lap joint includes a stub end or taft. The lap joint is very easy to assemble and align because it is used in low pressure only. A hub is included in a lap joint ring flange but some will not provide to reduce the cost.

BLIND RING FLANGE

Blind ring flanges are not connectors they are like stoppers. Blind ring flanges are blank because they are used in the end or fitting for periodical inspection only.

SOCKET WELD RING FLANGE

In socket weld ring flanges the bore of pipe and the flanges both are same, it helps to provide the good flow. The receiver pipe also bored because the socket weld flange and the receiver pipe should tighten.

WELD NECK RING FLANGE

In weld neck ring flange the boring area and the flanges must be matched to avoid problems inside the pipe. In critical applications the weld neck is durable.

SLIP-ON RING FLANGE

The slip-on ring flanges don't have neck, it only has a molding area to fit with the pipe. In fabricated applications, the slip-on ring flange is very easy to use.
