What is Stainless Steel Lap Joint Flanges?
A stainless steel lap joint flange follows a two-component assembly with a stub end and a ring-type lap joint placed over it. This stub end is butt-welded to the pipe and can be easily rotated to align it with a mating flange. They are used as backup flanges and possess similar strength as a slip on flange. A SS lap joint flange is seen in applications where frequent dismantling and inspection of the piping system takes place. They are recommended in low-pressure and temperature conditions.

Where do you put SS Loose Flange?
A SS loose flange is commonly installed in place of a flange, where it is difficult to move the module. These flanges swivel around and don’t come in much contact with media thereby reducing corrosion in harsh environments.

EN 1092-1 Lap Joint Flange advantages and disadvantages?

Is a Carbon Steel Lap Joint Flange raised face?
A carbon steel lap joint flange is made with a two-component assembly. The nature of the joints and the stub end face allows them to be flange facing, which acts like a raised face flange, wherein a gasket can be inserted to seal the surface.

What is PN10 LJ Flange and PN16 Lap Joint Flange?
PN 10 LJ and PN 16 lap joint flange specify both pressure class and metric dimensions. The PN 10 lap joint flange is rated at pressures up to 10 bar. A lap joint PN 16 flange is pressure rated at 46 bars.
