split ball valve Feature as follow l applicable temperature-46 150. l applicable mediumnatural gas. l valve typeWB1,forged steel,fully welded. l pressure classANSI Class150. l face to face dimension and end to end dimension API 6D/ANSI B16.10. l bore,.API 6D.Full bore according to valve datasheet. The min. diameter for bore as per API 6D l End:WE,ASME 16.25,ASME B31.8.,,500mm,L290.,,.,.,≤3 kJin,.VASA.welding ends, conforming to ASME16.25, the size of slope conform to ASME B31.8. Transition pieces or pups is according to the requirement of valve data sheet, both end of valve will furnish transition pups, the length is 500mm and material is L290. When welding between transition and valve, welding art will adopt warm-up , in the process it should control the temperature. After welding, it will cold slowly and reduce the welding stress. We will control welding arts strictly and adopted less than (≤)3 kJin to weld. It reduced the input heater. After welding it will adopt VASA vibration to eliminate the rudimental stress. l Design:API6D.ASME VIIIANSI/ASME B16.34,,,,.valve design conforms to API6D standard and specification. The min thickness wall of bear device conform to ASME Boiler and Pressure Vessel Code Section VIII and ANSI/ASME B16.34. The valves is with enough strength and rigidity, so the valves performance fully meet the requirements according to the working condition, and ensure the valve can safely run under working condition and ensure the valves running life.
