Forged Flanges

Slip On Flange

Place two fillets by welding, sliding inside the tube. So its installation cost is lower, requiring less precision in cutting the pipe

WELDING NECK

They join the buttwelded pipe. They are preferred when radio graphed joints is required, or when e fforts are highest on the union. The long conical neck optimazis stress distribution.

Blind Flange

Developed especially for small diameters and high pressures. Tube is inserted in them to the seat and then is welded in against the cube steak.

Threaded Flange

They are placed in pre-threaded pipe, usually in places where welding cannot be applied. Not recommended for use in systems with intense pressure variations.

Overlapping sliding on a board. Usually used in places where it is often necessary to disassemble for cleaning or dismantling reparaciones.El cost decreases because of the ease of turning the flanges and align the holes.
