Product Details
The flange connection is easy to use and can withstand large pressures. In industrial pipelines, flange connections are widely used. Within the family, manage
The diameter of the channel is small, and it is low pressure, so the flange connection cannot be seen. If there are flange connected pipes everywhere in a boiler room or production site
Dao and equipment.
Simply put, the function of a flange is to fix and seal the connection of the pipe fittings.
The stainless steel flange has a beautiful appearance and a flat and smooth surface. It is mainly used for connecting carbon steel pipelines, and its nominal pressure does not exceed 2.5MPa.
Flat welded flanges are acid and alkali resistant, corrosion resistant, and have strong texture and function. They are cut using an oxygen furnace, and may be forged or cut into shape as a whole
It is formed by high-precision CNC lathe turning and CNC rocker drill drilling.
The connection method for flat welding flanges includes single sided welding and double sided nut connection. When welding, only single sided welding is required without welding pipes and flanges
The inner port of the connection is generally used for low and medium pressure pipelines.
The sealing surface of flat welding flanges can be made into three types: smooth, concave convex, and tenon groove. During this period, the application of smooth flange plates is mostly used for
When the medium conditions are relatively flat, such as low-pressure non purified compressed air and low-pressure circulating water.,
Flat welding flange is a type of flange that is directly welded to equipment or pipelines through fillet welds. Simple structure and convenient processing. Its stress characteristics
Between the integral flange and the loop flange, flat welding flanges are divided into two types: plate type flat welding flanges and neck type flat welding flanges. Flat welding flanges have low cost and production cycle
Short term, it is a commonly used flange type and is widely used in various fluid pipelines.
