DIN 2632 Flange WN flange Carbon steel PN10

Flange is to make the pipe with pipe connecting parts, connection in the pipe end.On the flange hole, can wear bolt, make two flange.The flange gasket seal.Butt welding flange is refers to the neck and a circular tube transition, and the pipe butt welding of the flange.


Butt welding flange sealing good, not changeful form, due to the solder joint seal face far distance, can avoid the hidden trouble of the sealing surface deformation.Its joint is beep physique structure, suitable for high temperature and high pressure pipeline, commonly used in PN is greater than 2.5 MPa pipe and valve connection;Also used to transport is expensive, inflammable, explosive medium on the pipeline.
In bulk flange packaging can be divided into three categories: basically, wooden packaging and packaging fumigation-free packing box.The export flange is usually wooden packing or fumigation-free packing box packaging;Domestic flange, mostly in bulk, there is also a part of because the journey far, some flange of meticulous packaging requirements, with wooden packing or flange with foreign trade, are fumigation-free packing box packaging.


Bulk without cost, so most of the flange customers to save money without the use of packing, on the other hand also because domestic flanges are generally from the flange factory directly after delivery to the site to use.The use of packing is also a kind of resource waste, generally in order to prevent rust on the way, appearance can apply anti-rust oil;Wooden packaging sealed box is cheaper, compared the flange on the wooden pallets, daub good anti-rust oil or black paint on the outside with winding belt winding fixed well, scattered, prevent transit then fixed with packing belt;Most expensive fumigation-free packing box, but look best preserved, there will be no transit knock against, the foreign trade customer like this way of packing.


Three kinds of packaging each have advantages and disadvantages, the specific use which kinds of packing also need according to the actual situation to determine.


The butt welding flange forging products is generally, also there is a small amount of scooter in the system.It belongs to the single side welding, double nut connection form of connection, mainly use high precision CNC lathe or semi-automatic nc lathe turning.


Butt welding flange of main material is carbon steel, stainless steel, alloy steel, etc.
