Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

it is possible to be produced in varying types, shapes, sizes, and
grades of bars to cater the exact technical requirements. Steel
bars generally have the shapes such as flat, round, hexagonal,
square and channel and on most of the occasions, it is the shape
of the bar that defines its application area

SAE 304 stainless steel is the most common stainless steel. The steel contains both chromium (between 18% and 20%) and nickel (between 8% and 10.5%)[1] metals as the main non-iron constituents. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel. It is magnetic, but less magnetic than steel. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes.[1]

t moderate temperatures, Werkstoff No 1.4301 SS 304 Flanges can also deliver a good performance in caustic solutions, especially those solutions that are free of chlorides or fluorides. Although grade 304 performs well in freshwater applications with low levels of chlorides i.e. less than 100 parts per million, exposure of the alloy to higher chloride levels makes the UNS S30400 304 Stainless Steel Flanges susceptible to both crevice corrosion and pitting.

Common stainless steels include 304, 304L, 316, 316L, 347, 310S, 904, etc. They all contain chromium, nickel and other chemical components. For example, the addition of molybdenum can further improve the atmospheric corrosion, especially the corrosion resistance to the atmosphere containing chloride.
