76X6 seamless steel tubes with large flanges?
76X6 maximum allowable pressure for seamless steel tubes:20 steel for 12MPa (take thickness negative deviation forming, allowance= 12.50%, corrosion allowance corrosion, allowance (mm) =2)0Cr8Ni9 steel is 20MPa (take negative deviation of thickness, forming allowance= 12.50%, corrosion allowance corrosion, allowance (mm) =0)Therefore, 150 or more than 200 kilograms should be fitted with flanges
DN65 to see the pressure of low pressure plate welding flange PL or SO hard flat high voltage WN butt welding is resistant to corrosion or if it can wear SO
With DN65 neck welding flanges.According to the thickness of the steel pipe pressure, at least use 63kg pressure flange.. WN65-63KGHG/T20595-97 or HG/T20595-2009 implementation standards.As for the sealing surface, you can choose your own,Select the sealing surface can be found inside our company website.
