Threaded Flanges

Cromwell Distribution is a specialised Stockist of high quality ASME/ANSI/DIN standard threaded flanges or screwed flanges . We offer immediate delivery programs for standard size of carbon steel threaded flanges and stainless steel threaded flanges. Threaded flanges are widely used in low pressure piping systems, as no welding is involved while connecting the flanges to pipes or other equipment. However, the flange may be welded around the joint after assembly, but it is not considered a satisfactory method of increasing its applications. Threaded flanges are also known as screwed flanges and are similar to slip-on flanges, but the bore is threaded to enable assembling without welding. Threaded pipe flanges are usually used with pipes that have external threads.

We offer threaded pipe flanges at our facility to companies in various industries including shipbuilding, power generation, petrochemical plants, oil refineries, waste water treatment plants, paper mills, pharmaceutical plants and turnkey projects among others.


What is Threaded Flange ?

Threaded Flanges are also known as a screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe. Threaded Flanges are mostly used in utility services such as air and water.

The benefit of these Threaded Pipe Flanges is that it can be attached without welding. When a raised face is necessary for threaded pipe flanges, the standard height is 1/16″ for threaded pipe flanges under 400#. For threaded pipe flanges of 400# and up, the standard threaded pipe flange raised face height is 1/4″.
