What Is Mss Sp 44?


All materials used for making mss sp 44 steel pipeline flanges needs to be killed steel. Killed steel, used in the manufacture of mss sp 44 flange neck has been completely deoxidized by the addition of an agent before being casted. Which would mean that there is practically no evolution of gas in killed steel during solidification. Therefore, using killed steel in the production of flanges, as noted by mss sp 44 flanges suppliers in uae is characterized by a high degree of chemical homogeneity as well as freedom from gas porosities.

MSS Sp 44 VS ASME B16.47

MSS SP 44 VS ASME B16.47?

  • The mss sp 44 standard is well suited for field welding to other flanges, fittings, or pipe as well. Especially the asme b16.47 series a (mss sp-44) flanges is well suited to those components which have been manufactured according to the following specifications – i.e. ASTM A105, A53, A106, A381, A516, A350, A537, A694, A707 and API 5L.

  • ASME B16.47 vary from nominal pipe sizes 26 inches to 60 inches. ANSI B16.47 Blind Flange is a type which has a blind end. This is usually used in fluid flow systems where the pipe has to be closed.

Refer MSS-SP 44 Gasket Dimensions, PED Approved ASME B16.47 Series A (MSS SP-44) Flanges Manufacturer In India.


The standard used for mss sp 44 series b, based on ladle analysis, defines the maximum content of carbon i.e. 0.30%, and CE shall not exceed 0.48%, without prior approval of the purchaser. If the CE  in mss sp 44 flanges stainless steel exceeds 0.45%, the flange has to be marked with the actual CE result. All test methods to be conducted on the mss sp 44 flange gasket have to be as specified in ASTM A370.
