Stainless Steel WN flange and flat welding flange cannot be replaced casually. From the manufacturing point of view, the large inner diameter of flat welding flange means small weight and low cost. The neck butt welding flange with diameter greater than 250mm shall be tested, and the flange of so does not need to be tested.
Stainless Steel WN flange is suitable for petroleum, chemical industry, plumbing, fire protection, electric power, aerospace, shipbuilding and other industries.
