plate flange actually slip over the pipe. The pipe flanges are typically made with an inside diameter of the pipe flange slightly larger than the outside diameter of the pipe. This allows the flange to slip 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. 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 1/2" thru 80". Slip on pipe flanges that consist of a flat ring have published specificiations that range from 1/2" thru 80".
We have adopted advanced production equipment and technologies to manufacture our weld neck flanges and blind flange, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
