Introduction of Slip-on Flange Forging Methods
This technical article introduces us about some main forging methods of slip-on flanges according to the movement of the forging die.
How to Correctly Select Flange
This technical article introduces us in details about that some main ways and methods that we can choose and select flanges correctly.
Thin-walled SS Tube Is Increasingly Widely Used

NDRC: Increase Gas Imports and Oil Reserves in Winter
The National Development and Reform Commission decided to increase gas imports and oil reserves in this winter in the meeting held on November 13.
How to Correctly Select Flange
(2) The parameters of the medium, working pressure, working temperature. Under the condition of the medium which is determined, determine PN, which is the nominal pressure of flanges according to the working temperature and working pressure of medium.
Now, take national standard as example, we explain the selection of flange. National standard flange are divided into two major systems: Europe system of and America system. The flange nominal pressures of Europe system are: PN0.25, PN0.6, PN1.0, PN1.6, PN2.5, PN4.0, PN6.3, PN10.0 and PN16.0 MPa. The flange nominal pressures of America system are: PN2.0, PN5.0, PN11.0, PN15.0, PN26.0 and PN42.0 MPa.
(4) According to the connection object, the flange specifications can be determined.
