Plate flat welding flange (chemical standard HG20592, national standard GB/T9119, mechanical JB/T81):
convenient to take materials, simple to manufacture, low cost, widely used; However, the rigidity is poor,
so it cannot be used in chemical process piping systems and high-altitude and extremely hazardous occasions with supply and demand, flammable,
explosive and high vacuum requirements. The main design disadvantage of flat welded flanges is that it does not guarantee leak-free.
