High Quality But Lower Cost CS Flange Manufacturers

The Carbon Steel Standard Flanges are useful to join a chain of pipes, tubes or flanges together. Some flanges need to undergo high pressure. For example in oil and gas sector, flanges are required to bear high amount of physical force. Hence at Devdeep Steel Alloys the flanges are tested before they are offered for sale to a specific sector. If the pressure demand is low the flange is welded. While where the pressure required is high the flange is either bolted or threaded. The flange standards define the pressure PSI (pounds per second per inch) according to dimension and size of pipe flange.

The Steel flange is made from material such as stainless steel, carbon steel, nickel alloys or the kind of threaded matter used for fittings. Every flange is classified to a particular class. From these class ratings, various necessity such as bolt and nut dimensions, pressure-temperature rating, material coating and various other factors. Hence make up the flange standard corresponding to the feature.
