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.

Flanged Limit Compensator Was Applied in Pipeline System
Flanged limit compensator was applied in pipeline system, especially in the compensation principle.
Compensator is mainly used in metal pipeline engineering at long distance, and it can achieve the goal of safe operation of the pipeline by taking advantage of stretching and shortening the pipe to compensate pipe installation error and run error.
Compensator can not only effectively makes use of themselves to compensate for pipe, but also limit axial compensation so as to avoid pull-off phenomenon of pipeline caused by overcompensation. In order to bring the use of safe and convenient experience for the general use in majority, let me explain for you about how flanged limit compensator applies in the pipeline system in detail.
The flanged limit compensator what we called is classified into two types:
1. Double flanged loose-tube limit expansion
The difference of the two main limit expansions is the way of connecting. Double flanged loose-tube limit expansion is adopted as interconnecting piece by using two flat pieces or convex flange through the connection of bolts and pipes. It is installed more convenient, but the cost is very high. It is recommended that these pipe fittings are not used as connection parts in the case of abundant human labor. Single flanged loose-tube limit expansion is used as interconnecting piece by using convex flange and flat flanged seat through the connection of bolts and pipes. Under the circumstances of the good condition of site construction, people can choose to install the flanged limit expansion pipe by electric welding. In the past of pipeline construction, there mainly exist problems such as pipe expansion production, installation difficulties, big space floor, serious phenomenon of running water, a lot of softened water erosion, and frequent maintenance and so on. Technical personnel design, produce limit expansion pipe at domestic and international leading level by referring to relevant information both at home and abroad on the base of long-term study and repeated practice. Finally, this product is widely used in all kinds of large-scale pipeline projects due to its stable performance.
