Abstract
The invention discloses a welding neck flange. The welding neck flange comprises a flange plate. A welding neck is arranged on one side of the flange plate. The inner diameter of the welding neck and the inner hole diameter of the flange plate are equal and communicate mutually. A reinforcing ring is arranged at the joint root of the welding neck and the flange plate. The circle center of the reinforcing ring is located on the central axis of the welding neck. A strengthening sleeve is further arranged at the tail end of the welding neck and is connected to the outer wall of the welding neck in a sleeving mode. The central axis of the strengthening sleeve coincides with the central axis of the welding neck. An annular boss is arranged on the other side of the flange plate. The inner diameter of the boss and the inner diameter of the flange plate are equal and communicate mutually. According to the welding neck flange, the reinforcing ring is additionally arranged at the joint of the flange plate and the welding neck, the strengthening sleeve is arranged at the tail end of the welding neck, the connecting strength of a flange body and a pipe body is greatly improved after the welding neck flange and the pipe body are welded and molded, and the situations of deformation and fracturing are not liable to occur.
Description
Technical field
The present invention relates to a kind of flange, more precisely, being a kind of hubbed flange.
Background technology
Hubbed flange the height of neck is higher, and the rigidity, bearing capacity to flange increases.Compared with W.N flange, weldering
Connect workload big, welding rod consumption is high, and Jing does not play High Temperature High Pressure and alternating bending and temperature fluctuation, but in-site installation is more convenient, can
The operation of weld seam film making flaw detection is omitted, it is more welcome.The end of the ring flange and hub of the hubbed flange for commonly using at present this
Two positions are susceptible to the situation for deforming, rupturing after welding fabrication, and the self-strength of hubbed flange needs pointedly to carry
It is high.
The content of the invention
The present invention mainly solves the technical problem existing for prior art, so as to provide a kind of hubbed flange.
What the above-mentioned technical problem of the present invention was mainly addressed by following technical proposals：
