Mss sp 44 steel pipeline flanges are produced from killed or deoxidized steel grades. Which means that oxygen has been completely eliminated from the alloy of the steel MSS SP-44 Flanges with the addition of an agent before the steel could be cast. Therefore there is practically no evolution of gas during the solidification process of steel.
The term MSS SP-44 refers to the specifications for steel alloy pipeline flanges, which covers pressure temperature ratings along with the materials used to make these flanges, dimensions, tolerances and testing methods.

MSS SP-44 Flanges Standards
The grades of the mss sp 44 flange dimensions are as follows i.e. F36, F42, F46, F48, F50, F52, F56, F60, F65, F70, F80, The grade used with the flange is indicative of its yield strength. For instance grade F36 has a yield strength of about 36 ksi, whereas grade F80 would indicate the yield strength of the flange standing at a value of 80 ksi. Usually, the MSS SP-44 Flanges Dimensions are considered important as these flanges are used in process streams that can contain any amount of chemicals such as Hydrofluoric acid, boron trifluoride, Monoethanolamine, diethanolamine or compounds, where the weight is greater than % of the solutions. Furthermore, it is necessary to keep a track of the mss sp 44 flanges weight in applications where hydrogen is an integral part of, in the process stream to prevent stress cracking. This includes the use of MSS SP 44 Class 150 Flanges, which are exposed to hydrogen sulphide either in an aqueous phase or in instances where the water contains liquid H2S.
