The American National Standard was developed and published by the Manufacturers Standardization Society or the MSS of the Valve and Fittings Inc. The Standard practice for the MSS SP 44 Class 150 Expander Flanges covers pressure-temperature ratings, materials, dimensions, tolerances, markings ,etc. Apart from these parameters, the standard for Asme B16.47 Series A And Series B (Mss Sp-44) Flanges, also covers testing for steel pipeline flanges.
According to the document, the welding Carbon Steel MSS SP 44 Class 150 Flanges are to be required to be manufactured from forged steel. While the blind Mss Sp 44 Steel Pipeline Flanges could be made either from forged steel or from steel plate.The standard practice of the ANSI/MSS SP-44-2016 (Reissue 2017) covers pressure-temperature ratings, materials, dimensions, tolerances, marking, and testing for steel pipeline flanges. In accordance with the document, the welding neck type flanges are to be forged steel, while the blind flanges can be made from either forged steel or steel plate.
In the year 2016, the Mss Sp 44 Standard was revised. These revisions of the ANSI/MSS SP-44-2016 standard included major updates such as a Defined chemistry limits for the Mss Sp 44 Flanges Weight, Clarification the “lot” definition of the Mss Sp 44 Class 150 Flanges, Changed marking requirements, Added requirement for hardness testing, Made impact testing at -50 °F mandatory for grades with Mss Sp 44 Flange Dimensions over F42, Clarified allowable heat treatment methods. Apart from these additions there were some tolerances Added for raised face height and bolt hole diameter.
The added requirements for Manufacturing Procedure Specification and Inspection as well as Test Plans for the MSS SP-44 Flange include - a Removed ring gasket dimensions in reference with the ASME B16.20A, addition of Supplementary Requirements from the SR1 through SR16 and the Updated & renumbered the reference annex.
Key markets that use the Mss Sp-44 Material in their equipment or machinery include the use in Bitumen upgraders, Heavy oil refineries, Nuclear power, where the application is mostly seamless as well as the Petrochemicals and acid industries. .Production technique for the MSS SP 44 Class 150 Square Flanges includes Forging, Heat treatment as well as machining.
Most commonly, the MSS SP 44 are available in the markets types include – Forged, Threaded, Screwed or Plate. Generally the Mss Sp 44 Standard flanges are surface treated by Coating. Coating these flanges can be done by using Anti-rust Paint or Oil Black Paint. Another important surface treatment technique employed by the manufacturers of Mss-Sp-44 Weld Neck Flange In India include plating or galvanization. Thus, these flanges are available in either Zinc Plated, Yellow Transparent or Cold and Hot Dip Galvanized as required by the buyers.
The Size Chart for the Stainless Steel MSS SP 44 Class 150 Flanges ranges between ½ inch (15 NB) to 48 inches (1200NB) DN10~DN5000, While the Mss Sp 44 Flange Pressure Rating ANSI starts from Class 150 LBS to about 2500 LBS (therefore including pressure ratings like - 300 LBS, 600 LBS, 900 LBS, 1500 LBS)
