Flat welding
诚德
Plate type flat welding flange (chemical standard HG20592, national standard GB/T9119, mechanical JB/T81): easy to obtain materials, simple to manufacture, low cost, and widely used; but the rigidity is poor, so it should not be used in areas where supply and demand are high, flammable, and easy to use. Chemical process piping systems with explosive and higher vacuum requirements and highly and extremely hazardous situations.The sealing surface types include flat and raised surfaces.
