WN, SO, BL, TH, LJ and SW are the abbreviations of what words are. How do you translate Chinese? Class 150 is the stress level. Does that mean the pressure is 150 Bar? Thanks
The 1 floor is written in English, but the translation is not professionalThese abbreviations refer mainly to the welding structures of flanges, necks and tubes or nozzlesWN [neck welding flange]Is [SO] hubbed flangeBL is [flange], also known as "blind plate.""
[note] the nominal pressure of 2, not less than or equal to 2.0MPa design pressure can use the pressure level of the flange, flange at different temperatures and different materials and different types of sealing surface and welding structure have different maximum design pressure.Generally, the design pressure of 2.0MPa is usually hovering between 1.6 and 2.0MPa, and detailed data are shown in HG/T 20615-2009, Ministry of chemical engineering, flange standard
TH [threaded neck flange]LJ is a loose flange, which is no longer available in the new standard in 2009 and has been modified to [LF/SE, welded ring, loose flange]SW is the socket weld flangeClass 150 is the stress level in the American ASME standard system,China's Ministry of chemical industry standard cited the European and American standards system, so the introduction of this pressure rating systemClass150=PN2.0= nominal pressure is 2.0MPaClass300=PN5.0= nominal pressure is 5.0MPaWait, waitBar is the unit of pressure, and 1Bar is approximately equal to 0.1MPa,Landlord can push like this
