Threaded Flanges are used for special circumstances with their main advantage being that they can be attached to the pipe without welding.

Stainless Steel Threaded pipslipe flanges are similar to -on pipe flanges except the bore of threaded pipe flange has tapered threads. Threaded pipe flanges are used with pipes that have external threads. The benefit of these pipe flanges is that it can be attached without welding. Threaded pipe flanges are often used for small diameter, high pressure requirements. Slip on Pipe flanges with a hub have published specifications that range from 1/2" thru 24". Kobs Flange provides Slip-On pipe flanges in all material grades, specifications and sizes.

Stainless Steel Threaded pipe flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for threaded pipe flanges, the standard height is 1/16" for threaded pipe flanges under 400 ( 2.4360)#. For threaded pipe flanges of 400 ( 2.4360)# and up, the standard threaded pipe flange raised face height is 1/4".

Kobs India Flange manufactures threaded pipe flanges in all steel material grades, including carbon threaded pipe flanges, stainless steel threaded pipe flanges and alloy threaded pipe flanges. Kobs Flange also has many different threaded pipe flanges in stock and ready to ship.

Manufacturing Process :

The manufacturing process of flange mainly is divided into forging, casting, cutting and rolling. .

The casting and forging flanges have advantages that the blanks of them have accurate shape, size and low costs and only need simple process. But forging flanges have manufacturing defects such as blowholes, cracks, etc and have not very smooth internal organization streamline. The obvious advantages of forging flanges are that they can be forged in various shapes and they have low costs. .

Forging flanges generally have lower carbon content than the casting flanges and are not easy to rust. They have smooth streamline, uniform internal organization, and better mechanical performance than that of casting flanges. There are no defects, such as blowholes and cracks existing in the casting flanges. Forging flanges are able to withstand higher shear and drawing forces than casting flanges. However, if adopting improper forging process, it will also cause appearance of large, uneven grains and solidification cracking phenomenon, resulting in higher cost than the casting flanges. .

We can distinguish between the casting flanges and forging flanges from the different production process. To take the centrifugal flange as an example, it is a kind of casting flange. Centrifugal flanges are produced by a precision casting method, which makes the flanges’ organization smaller than those commonly produced by sand casting and improves the quality of flanges, making fewer occurrences of loose tissue, pore, sand hole etc.

Cutting process refers to producing flanges by directly cutting a round plate with the inner diameter, outer diameter and thickness which can be further processed later from the middle plate, and then processing the bolt hole and waterline. The maximum diameter of such flanges is limited by the width of the middle plate.

Cutting process refers to producing flanges by cutting stripes from the middle plate and then rolling them into round shape. This process is mainly used for the production of large flange. After the rolling process, weld and then flatten the round shape, and finally process the serrated spiral finish and bolt hole.
