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
With the implementation of reform and opening policy and the development of economy, thin-walled stainless steel tubes are more and more popular.
Venezuela's Manufacturer Will Set Up Factories in Cuba

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.
Dimensions and Check Methods of Large Flange
Designated flange materials are low carbon steel (Q235 - A, 20g, etc.) and general low steel (16Mn, 16MnR and 15MnVR, etc.) in the large flange dimensions of large pressure vessel. A flat welding flange and b flat welding flange remain conversion relationship between their nominal pressure and maximum pressure of work under different temperatures. We can convert manipulation temperature in the designed premise to the required nominal pressure which can pick up the flange dimensions required nominal pressure. Large flanges of the actual amount are produced according to the correct materials and raw materials in order to ensure the accuracy of the design, good performances and characteristics of products during production process and extension of life and value in use. In addition to slip-on flange and butt welding flange, large flanges contain cast iron flange and cast steel flange, lap joint flange, threaded flange, etc. And the check methods and steps of large flange dimensions are the same with those of the pressure vessel flange.
