ST37.2 Steel Flange

ST37.2 Steel Flange

Leading Carbon Steel St37.2 Weld Neck Flange Manufacturer in India

ST37.2 is a low carbon steel grade. The ST37.2 Steel Flange is designed with a superior chemical composition of carbon, silicon, manganese, phosphorous, sulfur, and nitrogen. The content embedded in these flanges gives them good corrosion and oxidation resistance properties. The ST37 Flanges showcase superior strength and mechanical properties. These flanges exhibit a tensile strength between 360 to 460mpa with a minimum yield strength of 235mpa and can be easily elongated by 25% in the system.

Supply Din 2448 st 37 Slip On Flange and EN 1.0037 Plate Flanges with hydrostatic testing to ensure tightness and strength

The RST37.2 Slip On Flange is a common and most used flange in the industry. These flanges are very versatile and can be easily slid on the pipe fixture and are subsequently welded in place using one or more filler materials. These flanges are generally preferred for low-pressure and temperature applications. The versatile DIN 86044 ST37 Plate Flanges are designed with a flat, circular disc that is welded to the pipe and can be bolted easily to the other pipe grade. These flanges are usually used in fuel and water pipeline systems. A Din 2448 st 37 Socket Weld Flange is seen in smaller pipe sizes for high-pressure systems. The flanges are attached to the pipe by inserting it in a recessed area and welding it in place using a fillet weld on top of the flange. This allows the flow of fluid in the system to be very smooth and precise. The flanges range in sizes between 1/2 to 24 NPS. The EN 1.0037 Lapped Joint Flange is a versatile flange grade that is made up of two components. These components allow it to move around in the flange very easily without contacting any fluid or gases in the system. As they don’t contact any media, they possess a long service life. All our products are quality assured and produced with the best material.
