SP-58-2009 Pipe Hangers and Supports - Materials, Design, Manufacture, Selection, Application, and Installation (ANSI-approved American National Standard) This Standard Practice establishes the material, design, fabrication, and inspection criteria to be used in the manufacture of standard types of pipe hanger components. This Standard Practice establishes the allowable stress values for materials used in standard types of pipe support components and unique hanger design assemblies. This Standard Practice establishes minimum design load ratings for rigid pipe hanger assemblies (see Table 1). This Standard Practice presents the recommended practice for the selection and application of pipe hangers and supports for all service temperatures. This Standard Practice establishes recommended procedures for detailing, fabrication, and installation of pipe hangers and supports.

The American National Standard developed and published by the, MSS SP-44, which was last revised in 2016, has been reissued. Manual practico para la construccion jaime nisnovich pdf to doc word. The current edition is. Pipeline creation and maintenance makes use of heavy demands and distinctive components and processes. The line pipe is uniquely characterized by high-strength, cold worked, thin-wall of the carbon steel grade, which necessitates special considerations for the welding end of the flanges. This concern was present as far back of the establishment of this standard around fifty years ago, after MSS had received continued requests for steel pipe flanges for pipeline use, particularly in sizes larger than those covered. The standard practice 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. The pipe sizes covered by the standard, designated as the dimensionless nominal pipe size (NPS), are NPS 12 to NPS 60, in two number intervals, with dimensional and tolerance guidelines for NPS 10 and smaller being provided by reference to ASME B16.5. Please note that international standards make use of the nominal diameter “DN” system, and the corresponding values of these are listed in the document. Addresses flanges of Class, 150, 300, 400, 600, or 900.

The 2016 revision of the ANSI/MSS SP-44-2016 standard was major, and its updates included: • Defined chemistry limits (added a Table 1 and removed external references). • Clarified the “lot” definition. • Made impact testing at -50 °F mandatory for grades over F42. • Added requirement for hardness testing.

• Clarified allowable heat treatment methods. • Changed marking requirements. • Added tolerances for raised face height and bolt hole diameter. • Added requirements for Manufacturing Procedure Specification and Inspection and Test Plans. • Added Figure 4 to illustrate test locations and orientation.
