What is large caliber flange?

Large caliber flange is one of the flanges,it is widely used in mechanical industry,chemical industry,wind power industry,water and wastewater industry.It has been well received and favored by users.The production process is divided into the rolling system and the forging system.The large caliber flange material can be carbon steel,stainless steel and alloy steel.

Large caliber flanges are commonly flat welding flanges and butt welding flanges.In the actual production and sales,the proportion of flat welding products accounted for much.Flat welding large caliber flange and butt welding large caliber flange have different welding structure and range of use,and their characteristics and advantages are different,so when use the large caliber flanges need to conside the use range to ensure that the flange plays an important role.

Large caliber flanges

Large diameter flat welding flanges have poor rigidity and these are suitable for places where pressure is less than or equal to 4MPa.Flat welded flanges are widely used in the connection of medium and low pressure vessels and pipes.A butt welding flange is a flange that has a neck and is transitioned by a round pipe and is butt welded to the pipe.Butt welding flange is mainly used for the opposite welding of flange and pipe.Its structure is reasonable,its strength and rigidity are large,it can withstand high temperature and high pressure and repeated bending and temperature fluctuation.The sealing performance is reliable.The nominal pressure is 0.25~2.5MPa.

There are three types of large caliber flange sealing surface:flat sealing surface,suitable for low pressure,non-toxic medium occasions;male-female sealing surface,suitable for places with slightly higher pressure;Tenon groove sealing surface,suitable for inflammable,explosive,toxic media and high pressure occasions.Flanged pipe fittings of different properties have good product performance in different fields. They can be used in different places and Spaces and have different effects.
