MSS SP-44 Flange

Check MSS SP 44 Series A Flanges Dimensions in MM, Supplier of MSS SP-44 Steel Pipeline Flange in Mumbai

What is MSS SP-44 Flange?
An MSS SP-44 flange covers standard pressure and temperature rating materials that are available in standard dimensions, and tolerances for standard pipeline equipment. These flanges are available in sizes of DN 10 to DN 5000 and are available in pressure classes of 150 lbs to 2500 lbs. The MSS SP-44 grade flange is produced in socket weld, threaded, weld neck, slip-on, and lap joint configurations. Each of these flanges are produced in either raise, flat, or ring type joint facing.

Is Hydrostatic test required for MSS SP-44 Flange?
The hydrostatic test of the MSS SP-44 flange is not necessary. However, the test of the flange joint can be carried out at pressures that do not exceed 1.5 times the 38 degrees C rating.

MSS SP-44 Series A vs MSS SP-44 Series B
The MSS SP-44 is designed in series A and B specifications. The series flanges can be distinguished from key features.

• MSS SP-44 Series A flanges are heavy and are thicker when compared to the MSS SP-44 Series B grade.
• The series A flanges have a small bolt circle diameter compared to the series B flange.

MSS SP-44 Class 150 Flanges vs MSS SP-44 Raised Face Flange

• An MSS SP-44 raised flange has a higher face that allows them to work well in high-pressure and temperature conditions.
• The MSS SP-44 Class 150 flanges are designed to operate in lower pressure and temperature setups.

MSS SP-44 Gr F52 vs MSS SP-44 F60
The MSS SP-44 grade covers carbon and alloy steel flanges seen in the transmission of high-pressure liquids and pressures. These flanges can be distinguished on key features.

• The MSS SP-44 Gr F52 is designed with a minimum tensile strength of 415mpa with a minimum yield strength of 290mpa. They can be elongated by 20% in the system
• The MSS SP-44 Gr F60 is designed with a minimum tensile strength of 515mpa with a minimum yield strength of 415mpa. They can be elongated by 20% in the system.
