Product Description

Duplex steel S31803 socket weld flanges , as the name suggests is a biphasic steel bar, steel ingot or plate such as the production of raw materials for the flange, referred to as biphasic steel flange, flange is also called flange or protruding edge. It is the part that connects the pipe to the pipe. Connected to tube end.

There are holes on the flange, and the bolts can be worn to make the two flanges tightly connected. The flanges are gasketed. The flange connection consists of a pair of flanges, a gasket and a number of bolts and nuts. The gasket is placed between the sealing surface of the two flanges.

After tightening the nut, the specific pressure on the surface of the gasket will be deformed after reaching a certain value, and the uneven part of the sealing surface will be filled to make the connection tight without leakage. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection mode in pipeline construction.

Raw materials of Duplex Steel S31803 Socket weld Flanges

Biphasic steel flange uses biphasic steel as raw material for production, the so-called biphasic stainless steel is in the solid solution of its ferrite phase and austenitic phase about half, the general amount of small phase content also needs to reach 30%. When the content of C is low, the content of Cr is 18%-28% and the content of Ni is 3%-10%. Some steels also contain Mo, Cu, Nb, Ti, N and other alloying elements.

This kind of steel has the characteristics of austenitic and ferritic stainless steel, compared with ferrite, plasticity, toughness is higher, no room temperature brittleness, intergranular corrosion resistance and welding performance are significantly improved, but also maintain the ferritic stainless steel 475℃ brittleness and high thermal conductivity, with superplasticity and other characteristics. Compared with austenitic stainless steel, it has higher strength and better resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent corrosion resistance, is also a nickel nickel stainless steel.
