Slip On Flange, Brand Name : TK 3"

SLIP-ON PIPE FLANGES
Slip-on pipe flanges actually slip over the pipe. These pipe flanges are typically machined with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe. This allows the flange to slide over the pipe but to still have a somewhat snug fit. Slip-on pipe flanges are secured to the pipe with a fillet weld at the top and the bottom of the slip-on pipe flanges. These pipe flanges are also further catagorized as a ring or a hub. Ring pipe flanges and hub pipe flanges are both considered slip on pipe flanges because they both slip over the pipe. Slip on Pipe flanges with a hub have published specifications that range from 12″ thru 96″. Slip on pipe flanges that consist of a flat ring have published specificiations that range from 12″ thru 144″. TongKang Flange provides Slip-On pipe flanges in all material grades, specifications and sizes.
Slip-On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers. However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation. Moreover, weld-neck flanges have a higher life expentancy than slip-on flanges under duress.
The slip-on flange is positioned so the inserted end of the pipe or fitting is set short of the flange face by the thickness of the pipe wall plus 18 of an inch, which thus allows for a fillet weld inside the SO flange equal without doing any damage to the flange face. The back or outside of the slip-on flange or SO flange is also welded with a fillet weld.
