DSS SDSS SS Slip On Flanges With Pressure Rating 150lbs PN16

DSS Flanges means duplex stainless steel flanges i.e. UNS31803 flanges and 2205 flanges, and SDSS is short for Super duplex Stainless steel Flanges, Duplex Stainless Steel (DSS) has a matrix consist of austenite and ferrite in approximately same volume. DSS has both excellent corrosion resistance and high mechanical strength. Therefore DSS flanges are suitable for sever environments like subsea piping system of corrosive oil and gas.SDSS has a better corrosion resistance than DSS and is therefore widely used in desalination, offshore oil and marine heavy industry. We offer super duplex pipes, super duplex fittings, UNS32750, SAF2507, A182 F55, A182 F53 flanges and more.

Technology/ How to use and install the different flange types

WELDING NECK FLANGES

They are connected to the pipe by means of a Butt weld connection. They are

used when X-ray testing is required or if the torque over unions are maximum.

Its long tapered neck optimizes the stress distribution

SLIP-ON FLANGES

This kind of flanges are installed with two weld bead, sliding the pipe inside.

Thus installation costs are lower, so less accuracy is required for pipe cutting.

THREADED FLANGES

They are usually installed with the pipe previously threaded, in places where

welding cannot be done. We do not recommend to install if there are high

pressure variations in the system

LAP JOINT FLANGES

They slide on an overlapped gasket. They are commonly used where it is

necessary to dismantle in order to be cleaned or repaired. Dismantling cost

decreases due to the ease of flange turning and drilling alignment.

.

SOCKET WELD FLANGES

This kind of flange is especially designed for lower small diameters and high

pressures. The pipe is inserted into the flange up to the seat and then is fillet

welded against the cube.

BLIND FLANGES

Blind flanges are utilized for pipe ends, and they bolted to any of the above

flange types.
