15CrMo Flanges

15CrMo Flanges

One of the leading Alloy Steel 15CrMo Weld Neck Flange Manufacturer in India, Check Sizes and Weight Chart of DIN 17200 Plate Flange

The 15CrMo grade covers structural steel grade that is designed with low content of alloys. The 15CrMo Flanges are manufactured with a chemical composition of carbon, manganese, silicon, chromium, molybdenum, sulfur, phosphorous, and niobium. The superior content gives these modules superior resistance to corrosive media and oxidative reducers in different setups. A DIN 17200 Plate Flange is a versatile quenched or tempered structural flange. These flanges are designed with a flat cross-section, and the circular disk is directly bolted to the subsequent pipe module. The 15CrMo Alloy Steel Slip On Flange is a popular flange grade that is slid on the piping component and welded in place using one or two fillet welds. The cost-effective flanges are preferred in low-pressure and temperature systems.

A wide range of 15CrMo Alloy Steel Blind Flange and 15CrMo Structural Steel Lap Joint Flange Designed To Meet All Your Needs.

A 15CrMo Alloy Steel Blind Flange is used to cut the flow of high-pressure and temperature fluids and gases. These flanges don’t have a boring center or face type. They are directly bolted to the system and allow room for maintenance and repair. The DIN 17200 Spectacle Blind Flange is a safety device that is similar to a blind flange. However, they have a spacer and a blank end. To stop the flow of fluids, a blank end is placed to curtail the flow, but the open end spacer can be used to allow for the movement of water. These flanges are generally installed in applications where repair work is taking place. A 15CrMo Steel Socket Weld Flange is utilized in small pipes for higher pressure pipes. These flanges are attached to the module by inserting the pipe into the end of the socket and applying a fillet weld on top. This allows for a smooth bore ensuring a better flow of fluids and gases in the piping system. All these flanges can be customized as per requirements.
