Abstract
The invention discloses a hubbed butting welding flange with clamping grooves. The hubbed butting welding flange with the clamping grooves comprises a flange plate and a neck tube arranged on the flange plate. The hubbed butting welding flange with the clamping grooves is of a symmetrical integrated structure, the flange plate and the neck tube are provided with the same inner hole, the neck tube is of a cylindrical structure, a circular chamfer is arranged at the connecting position of the neck tube and the flange plate, eight installation holes used for fixing bolts are evenly distributed in the flange plate, the two concave clamping grooves are formed in the positions, located on the symmetry straight line where the eight installation holes used for fixing bolts are located symmetrically, of a tube opening of the neck tube, and a circle of concave grooves are formed in the lower end of the inner hole. The hubbed butting welding flange is simple in structure, reasonable in design, high in self-strength, high in durability, long in service life good in use effect, and more stable and firmer in fixation due to the structure with the clamping grooves and the concave grooves.
