The flanges are the elements that are linked in pipes to join with valves, boilers, pumps, among other devices. Next, we will mention some of the types, characteristics and advantages of these accessories.

SLIP ON FLANGES

They are those that are fixed to the interior and exterior that slide along the pipe to join them through two welding segments.

WELDED FLANGES

They are welded only on the external side for small gauge lines.

SCREWED FLANGES

This type of flange is assembled without welding, since its hole is threaded, so it can be applied in services with low pressures.

LAP JOINT FLANGES

Unlike the slip type, it stands out for the radius between the intersection of the face of the hole and the flange. The short externals are welded to the pipe while the flanges are kept loose.

WELDED NECK FLANGE

It consists of a long conical center to reinforce its application in high pressures. Thanks to the holes on the edges, the flanges can be fixed with bolts.

BLIND FLANGE

This flange does not have a perforated center, they are manufactured with the aim of covering the ends of valves and pipes, as well as sealing nozzles in pressure vessels, so they are only screwed to easily access the interior of the devices.

REDUCING FLANGE

Reducing flanges are fundamental components in piping systems when a change in the size of the pipe is required. Its function is to connect tubes of different sizes.
