Product details

Flat welding flange (chemical standard HG20592, national standard GB/T9119, mechanical JB/T81) : easy to draw, simple to make, low cost and wide use; However, the rigidity is poor, so it must not be used in the occasion of supply and demand, flammable, explosive and high vacuum degree requirements of chemical process piping system and height and extreme harm. The cover type has plane and surface.
