Manufacturer of ANSI B16.5 SS Threaded Flange in Mumbai, India, Stainless Steel Screwed flange Suppliers.
EN 1092-2 PN16 Threaded Flange Dimensions & MSS SP-44 Reducing Threaded Flange Price List, Stainless Steel Threaded Flange manufacturer in India.
reducing threaded flange ASME B16.5 are meant for both Pipe as well as Flanged Fittings. The specification for the ASME B16.5 Threaded Flanges Standard covers, tolerances, marking, testing, pressure &temperature ratings, materials including methods of designating openings for pipe flanges and flanged fittings. Apart from all these parameters, the specification also covers ansi 150 threaded flange dimensions and includes the following points:
(1) ASME B16.5 stainless steel threaded flange with pressure rating class designations i.e. class 150, class 300, class 400, class 600, class 900, and class 1500 in a size range between NPS 1/2 up to NPS 24 and npt threaded flange with pressure rating class designation class 2500 is available in sizes NPS 1/2 till NPS 12. The requirements of the threaded weld neck flange have been given in both metric as well as the U.S. Customary units with diameter of bolts and stainless steel threaded flange bolt holes expressed in inch units;
(2) flanged fittings with rating class designation 150 and 300 in sizes NPS 1/2 up until NPS 24, with requirements of these threaded flange din 2566 fittings as mentioned in both metric and U.S. Customary units with diameter of bolts and npt threaded Flanges bolt holes expressed in inch units.
(3) flanged fittings with rating class designation 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and fittings like the threaded Flanges with rating class designation with threaded reducing Flanges for class 2500 in sizes NPS 1/2 up until NPS 12. These have been acknowledged in the specification in Non-Mandatory Appendix E section of the threaded Flanges pn16 in which only U.S. Customary units are provided.

ASME B16.5 Screwed Flanges has been limited to flanges and flanged fittings made from materials such as cast or forged materials. While blind flanges and certain reducing flanges could be manufactured from other metals such as cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding the threaded Flanges dimensions for purposes such as bolting, flange gaskets, and flange joints.
This ASME B16.5 Threaded Flanges Standard is to be used by npt threaded Flanges manufacturer in combination with equipment’s that have been mentioned like the other volumes of the Standards in ASME B16 Series as well as with other ASME standards, like both the Boiler and Pressure Vessel Code as well as the B31 Piping Codes. The ASME B31.3 Piping Guide mentions :
When the steel pipe is threaded and is used for steam applications above 250 psi or for water service above 100 psi with water temperatures above 220° F, the pipe must be seamless and the thickness must be at least equal to schedule 80 of ASME B36.10.
Although still available in most sizes and pressure ratings, screwed fittings today are used almost exclusively available in smaller pipe sizes. Click here to know more about the threaded flange price in India.
What is ASME B16.5 Threaded Flange?

The a105 threaded flange can be used for special circumstances. One of the main benefits of using the ansi 150 threaded flange dimensions is that their main advantage is that they can be attached to the pipe without the need of any welding process. Sometimes a seal weld on the reducing threaded flange could also be used in combination with the threaded connection.
