Leading SAE 4140 Weld Neck Flanges Manufacturer in India, Check latest price list of UNS G41400 Blind Flanges

AISI 4140 Flange

Connections made through valves, pipes, and tubes are essential in transporting media for different refineries and factories. Flanges are one of the efficient means of connecting different piping equipment. The AISI 4140 Flange is a chromium-molybdenum grade that has lower alloy steel. These flange allow workers to easily inspect and modify the system. They are very easy to maintain and install in the piping grade. Alloy 4140 Pipe Flanges are seen in different pressure and temperature setups. These flange provide stability and strength to pipes as there is the movement of pressurized gases and fluids. The SAE 4140 Industrial Flange are designed in pressure classes from 75 to 2500 and so on. These flange have good resistance to corrosive media and are available in raised, flat, and rtj face types.

The AISI 4140 Slip on Flanges is slipped over a pipe and welded on their interior or exterior to ensure a leak-proof sealing. These flange are preferred by engineers in the oil and gas industry as they are cheap and are very reliable in their functionality. SAE 4140 Weld Neck Flanges possess superior strength and are seen in high-pressure conditions. These flange are recognized by a tapered hub, allowing them to be used under repeated bending as they transfer the stress on the system. The UNS G41400 Blind Flanges are produced without a bore and are used to seal the ends of pressure vessels or valves. These flange are usually bolted and are common in different pressure conditions. A DIN 1.7225 Socket Weld Flange has a similar strength to a slip on flange and is preferred in piping equipment that are in sizes less than 2 NPS. The corrosion issues with these flange restrict their use in certain applications.
