Hydro is most trusted and famous manufacturer and supplier of Carbon Steel Flange with an ISO 9001:2008 and PED Certifications.
Carbon Steel Flange is a ring or collar (or disc) which is attached to the pipe or you can say Carbon steel flange is a raised part of solid which provides strength and acts as an attachment to another object. A Carbon steel is a steel which has carbon as its main alloying element with a range of 0.12-2.0%. No doubt, the steel becomes strong and hard during heat treatment when there is more amount of carbon content in it. As a matter of fact, the ductility and weldability also reduce. Hence, the higher the carbon amount, the lower is the melting point. The classification of carbon steel is on the basis of the amount of carbon present in the steel. Hence, it includes four main classes which are soft or low carbon steel, medium carbon steel followed by high and ultra-high carbon steel.Hydro Flange manufactures pipe flanges ANSI, AWWA, API pipe flanges in stainless steel, carbon steel, chrome steel and alloys. On the other hand, we produce Blind, Threaded, Weld Neck, Slip on, Socket Weld, Ring, Lap Joint, Orifice Flanges and custom flanges starting in sizes 1/2″ to 203″. From here on, these includes pressure classes from – 75, 125, 150, 900, 175, 250, 300, 350, 400, 600, 1500, 2500, 5K, 10K, 15K, 20K and high Yield with low Temperature.

Welding a way to install a pipe flange. All you need to do is just weld the flange onto the pipe. However, Hydro Flange also manufactures Lap Joint and Threaded flanges which don’t need special installment tools.

Bolt holes

Another method of connecting flanges is by breaking bolt holes having equal space into the flange which is aligned with the corresponding flange and further you can fasten them with bolts. In addition, we supply bolt hole patterns as per the customer’s specifications. Moreover, all our flanges are according to the ASME B16.47, MSS-SP44, API, ANSI B16.5 and AWWA-C207 standard levels.Other than carbon and stainless steel Flanges, Hydro flange holds expertise in manufacturing flanges in various material grades such as titanium flanges and aluminum flanges. This two kind of flanges is mainly used for the strength they maintain and for the weight they save. Other important flange materials produced by Hydro Flange include Inconel, hastalloy, and incoloy. They are applicable in areas of high-temperature surfaces. Similarly, for applications of low temperatures, we manufacture regular carbon steel flanges partnered. With this, we also produce high yield carbon steel flange for their use in modern pipe infrastructure and low-temperature usage.
