SO Flange Factory believes that in the medium and low pressure column with sight glass, due to the high working temperature and strong liquid corrosion and corrosiveness, it is easy to cause damage to the glass of the liquid level gauge sight glass, deformation of the bottom flange of the sight glass, and the installation of the sight glass. In the process of mirror flange glass, sometimes due to uneven force, the neck flange is easy to cause the mirror glass to break.

　　SO flange factory Any connection parts that are bolted on two planes at the periphery and closed at the same time are generally called "flanges", such as the connection of ventilation ducts, this type of parts can be called "flange parts". Flat welding flange is a kind of flange that is directly welded to equipment or pipelines through fillet welds. Simple structure and convenient processing.

　　SO Flange Factory found that its force characteristics are between the overall flange and the loop flange. Flat welding flanges are divided into two types: plate flat welding flanges and neck flat welding. Flat welding flanges have low cost and production cycle. Short, is a more commonly used flange type, widely used in various fluid pipelines. Relatively speaking, the rigidity of the flat welding neck flange of SO flange factory is slightly lower than that of the butt welding flange. Due to the long time, there are a lot of other colors on it, and it doesn't feel so white.

　　SO flange factory stainless steel flanges are suitable for pipeline systems in industries such as petroleum, natural gas, chemical, hydropower, construction, and boilers. They do not require tube blanks as raw materials, which can save the cost of pipe-making equipment and molds, and can obtain any large diameter and relative wall thickness It is a relatively thin national standard flange.
