Credibility ,Stainless steel flange easier due to the pressure fluctuations, temperature fluctuations, vibrations and shocks are not serious occasions during welding assembly line, or only when the alignment flange bolt holes in the rotation method Portland rather than the rotation of the tube. Calculated according to the internal pressure, generally used for pressure, low temperature, construction costs cheaper.
Only 10% of the fatigue life of welded flange. Because in the vicinity of the welding flange. Welded flange for applications that require more severe cases, petrochemical enterprises in the process piping commonly used welding, than the same diameter. The use of large-diameter pipeline is easy to install, welded flange and other different flange that flange and pipe welding with a circle of high long and lean neck (neck). In the petrochemical business in public works mostly for the pipeline.
