DIN Threaded flange DIN2656 PN6
Threaded flange is the inner hole of the flange processed into pipe threads, and with the threaded pipe matching to achieve connection, is a non-welded flange, flange is the inner hole processed into pipe threads, and with the threaded pipe matching to achieve connection. DIN Threaded flange DIN2656 PN6 is kind of hot-sell product. Considering the structural characteristics of threaded flanges, they are not suitable for inflammable, explosive and hazardous applications. Threaded flange applicable pressure 0.6-4.0mpa, diameter dn10-dn150. Threaded flanges shall be of the same size as plain welded flanges with neck, except for inner diameter thread dimensions. The sealing surface of screw flange has two types: full plane and protruding surface. Considering the structural characteristics of the screw flange. Therefore, it is not suitable for inflammable/explosive and highly hazardous situations. Low nuclear pressure, such as air conditioning water systems, is safe to use.
Compared with flat or butt welding flanges, threaded flanges are easy to install and maintain and can be used in some pipelines where welding is not allowed on site. Alloy steel flange has enough strength, but not easy to weld, or welding performance is not good, can also choose thread flange. But in the pipe temperature changes or sharply temperature higher than 260 ℃ below - 45 ℃ under the condition of threaded flanges are not recommended, so as to avoid leakage.

DIN Threaded flange DIN2656 PN6 features
1. The thread connection process does not consider the strength of the welding seam, which can ensure that the flange and the pipe body are tightly connected. The connection method is more sensitive and fast.
2. There will be no stress attack and no leakage of the interface due to weld stress attack cracks and welding defects.
3. It is useful to ensure the overall sealing of the pipeline by relying on the outstanding pipe joint of flange plate to connect with the rubber ring.
4. The flange heating and welding seam insulation procedures are omitted. The process is simple and the cost is reduced.
5. It is easier to ensure the straightness and parallelism of threaded joint flange pipe whether the flange hole is aligned or the flange pipe is aligned.
