Expander Flange Manufacturer in India

Expander Flanges, Expander Flanges Exporter, Expander Flanges Manufacturer in India, SS Expander Flanges Price, Best Quality Expander Flanges, Carbon Steel Expander Flanges Supplier, Stainless Steel Expander Flanges Stockists in Mumbai, India

Nishra Overseas LLP is a leading manufacturer, stockist, supplier, and exporter of Expander Flanges in India. Expander flanges are used to enlarge the bore of pipelines from one location to another in order to connect pipes to mechanical devices such as pumps, compressors, and cocks with varying cove sizes. The Expander Flange depicted is a weld neck flange with more drag on the non-flange end.

Expander Flanges – IBR and Non-IBR, ANSI B16.5 Expander Flanges, SS SOF Flanges Suppliers in India, Carbon Steel Expander – IBR and Non-IBR Flanges Exporter Supplier, EN1092, ASME B16.5 Expander Flanges Manufacturers.

Expander Flanges are welding neck pipe flanges with larger non-flanged ends on average than flanged ends. These flanges can be used to modify the pipe run of a given format. Expander Flanges are commonly used to increase line size to the second or first big sizes. These flanges are an alternative to using weld neck flanges with a certain reducer combination. Expander flanges are used to connect pipes to various components such as pumps, valves, and compressors.

ANSI B16.5 Class 150 Expander Flange are used to increase the run pipe bore by one or two sizes, but not any further. ASME B16.5 Expander flanges are less expensive than combining a butt weld pipe reducer with a regular flange (which is the conventional option for pipe drag increases above two diameters). The pressure conditions and range of expanding flanges are consistent with the ANSI/ASME B16.5 specification, and they are available with raised or flat faces (RF, FF).

Benefits of Expander Flanges

Aside from its great functional benefits, the expander flange also helps to reduce cumbersome inventory requirements and total installation, making it an essential component of many industries, including oil and gas, chemical processing, and power generation. As a result, this forward-thinking innovation continues to attract the attention of engineers and plumbers alike, boosting current plumbing capabilities to new and efficient heights.

An expander flange is a device that fits into an existing pipe to increase its diameter without replacing the full length of the pipe. It operates by expanding outward when pressure is applied to the inside of the pipe. This results in a more secure seal between two pipes and allows them to be joined with more strength than if they were simply connected at their existing diameters.

Expander Flanges Applications

Expander Flanges Marking

Every Standards have clearly requirements for steel flanges’ marking style, usually the marking words include seller’s Logo, buyer’s Logo (OEM), standard number, flange’s type, flange’s pressure, flange’s size, flange’s material, place of origin, heat number and other words for convenient to trace. If the flanges repaired by welding, it must mark on flanges showing this flange repared by welding. If the flange’s dimensions (OD, ID, PCD, Thickness, Holes number, Holes diameter, Tolerance etc) are different with the normal standard, it also must mark on flanges where it is different with normal ones. Another important place is heat number marking, it is the tracing base for every piece flange, and from the heat number we can trace to the beginning of raw material import.
