Expander Flanges Manufacturer

Specialized Expander Flanges Manufacturer, ASME B16.47 / ANSI B16.5 Stainless Steel Expander Flange Dimensions, Expander Weld Neck Flange.

Marcel Piping Projects Supply PVT LTD is prominent manufacturers, stockists, suppliers, and exporters of Expander Flanges in India. Expander Flanges are used to increase the bore of the pipelines from specific point to another to connect pipe to other mechanical device like as pump, compressors, and cocks that have different coves sizes. The Expander Flange represented is a weld neck flange with larger drag on non flange end.

Expanding flanges are used to increase run pipe bore only by one or two size and not further. Expander flanges are cheaper solutions to using a combination of a butt weld pipe reducer and a standard flange (which is the standard solution for pipe drag increases above 2 sizes). Pressure conditions and range of expanding flanges are in accord with the ANSI/ ASME B16.5 specification and are available with raised or flat face (RF, FF).

We are authorised exporters and suppliers of ASME B16.5 Expander Weld Neck Flange in USA, UK, Qatar, Mexico, Nigeria, Saudi Arabia, Kuwait, Iran, Kazakhstan, Bahrain, Vietnam, Indonesia, Norway, Ghana, Colombia, Azerbaijan, Libya.
