DIN 2631 flange PN6 welding neck flange stainless steel

Flange connection is the main connection Pipe Fittings equipment construction time, the two pipes or pipe fittings equipment together.First turn on the respective end fixed on the flange, there are generally two kinds of fixed methods, one kind is threaded connection, the interface position in pipe and the inner diameter of the flange position has a corresponding thread, the direct spinning twist together.This kind of connection mode is generally used in low pressure small flange pipe connection.The second is the flange welding to connect directly to the pipe ends, usually in the high pressure large diameter pipe flange connection is only used welding mode, it is safe and reliable, but not as good as threaded connection is convenient.

Two flange end face sealing surface, also called the water table.Runs above the seal groove, also called sealed water line, combined with the flange surface mat, after docking with the flange bolts or double stud together tightly, the pipeline fixed well.Different diameter, pressure of the flange, thickness and joint bolt diameter and need quantity is different.Some pipes or pipe fittings equipment, has own flange, it also belongs to the flange connection.This connection is mainly used in nonferrous metal pipe and the flange valve, cast iron pipe, lining hose connection.


The main advantage of flange connection is very convenient installation, simple operation, maintenance and easy disassembly;High strength, which can connect all kinds of pressure pipeline;Sealing performance is good, not easy to leak.To install, need to pay attention to two points: one is to pay attention to the installation should keep its balance when the flange, the second is the flange sealing surface of the installation must be clean, cannot have knock against, especially in the process of transportation, otherwise easy to seal is lax.Used in the flange gasket, want to choose more design regulations and cannot be used casually.Tomorrow I will give you a detailed explain mana shim selection
