The invention relates to a large-diameter welding neck flange with holes. The large-diameter welding neck flange with the holes comprises a flange body (1). The cross section of the flange body (1) is in a circular ring shape. The flange body (1) comprises a stainless steel layer (1.1) and a carbon steel layer (1.2). A protrusion (4) is arranged on the portion, close to the inner diameter, of the flange body (1), and is in a circular ring shape. A groove (5) is formed in the portion, close to the inner diameter, of the flange body (1). At least two outer holes (2) and at least two inner holes (3) are formed in the flange body (1) from outside to inside. By the adoption of the large-diameter welding neck flange with the holes, connection between two facilities or pipes can be firmer, the repair rate of the facilities or the pipes is reduced, and the service life of the facilities or the pipes is prolonged.
Description
technical field [0001] The invention relates to a flange, in particular to a butt welding flange with a large diameter and a high neck with a hole. Background technique [0002] Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between pipes and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. The traditional flange is composed of a flange body and a circle of holes. The connection between the equipment is not strong enough, and the bolts are easy to fall off after a long time. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a butt welding flange with a large diameter and a high neck with a hole that is securely connected. [0004] The object of the present invention is achieved in this way: a large-diameter...
