Threaded/Screwed Flanges Manufacturers in India

MSI Fittings is one of the largest manufacturer and supplier of Screwed/Threaded Flanges in India. Screwed Flanges are not suitable for circumstances including temperature or under cyclic conditions or bending stresses where leakage in the course of the threads may perhaps happen. Threaded Flanges are used for superior applications. They can be accumulated devoid of welding and can be used in very high pressure services, at or adjacent atmospheric pressure, where alloy steel is needed for power.


MSI Fittings is one of the leading Manufacturers & Supplier of Threaded Flanges in ASME B16.5 Material A182 Stainless Steel, ASTM A105 / API 6a Carbon Steel Threaded Flanges, Alloy Steel ANSI B16.5 Threaded Flanges - Class 150, 300, 600, 900, 1500, 2500 in All Sizes & Dimensions.

We are Manufacturer & Supplier of ASME 16.5 Threaded Flanges. Threaded Flanges (Screwed flanges) are similar to slip-on flanges in outline, but the bore is threaded, thus enabling assembly without welding. This obviously limits its application to relatively low pressure piping systems. Threaded Flanges may be welded around the joint after assembly, but this is not considered a satisfactory method of increasing the flanges’ pressure applications. Threaded flange use in low press condition usually. These flanges are normally designed for low pressure, non-cyclic applications. They are also used in applications where welding is hazardous. Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications.
