P355N Steel Flange

EN 10222-4 P355NH Blind Flange Manufacturer in India, Check Pressure Rating and Price list of EN 1.0562 Flanges

A P355N is a pressure vessel grade that has a high resistance to heat and brittle cracking. The P355N Steel Flange is a chromium and molybdenum grade designed with superior corrosion and oxidation resistance properties. The high-strength flanges are designed to provide support and stability to different fixtures across rigorous conditions. A Nace Mr0175 P355N Slip On Flange is one of the most common flanges in this grade. These flanges are slid on the piping fixture and welded using single or double fillet welds. They are generally preferred in low-pressure and temperature applications. The Alloy Steel EN 1.0562 Weld Neck Flange is a high-strength module that is designed with a long and tapered hub. This long neck allows it to provide support and strength to different fixtures as there is a vigorous flow of fluids and gases. The robust P355NH Carbon Steel Threaded Flange is threaded on the interior of the flange that aligns subsequently to piping fixtures having matching threads. These flanges are seen in use in low-pressure applications.

The En1092-1 P355N Socket Weld Flange is seen in smaller pipes for high pressure pipe grades. These flanges are put into a socket end of the flange and welded in place making use of a single fillet weld on the top. They are designed in sizes of 1/2 NB to 24 NB and allow for a smooth flow of media inside the fixture. An EN 10216-3 P355NH Orifice Flanges are used in measuring the rate of flow of liquids and gases in respective pipelines. These flanges are designed in a ring-type joint or raised face. A P355N Steel Plate Flange is designed in a flat or circular disc that is easily welded on the end of the pipe allowing it to be bolted to another pipe.
