Haokun A105 national standard blind flange to map processing .
Flange connection is widely used in industrial pipeline. In the family, the pipe diameter is small, and it is low pressure, and the flange connection is invisible. If in a boiler room or production site, there are flange connected pipes and equipment everywhere.
What should Haokun A105 national standard blind flange pay attention to when processing customized flange in connecting pipeline. The welding current should not be too large. In order to prevent the corrosion between eyes caused by the heating of the flange cover, 1 low-a hydrogen type should be dried at 200-250 ℃ for 1 hour (it can not be repeatedly dried, otherwise the coating is easy to crack and peel off), so as to prevent the oil and other dirt on the electrode coating, so as not to cause the carbon content in the weld and affect the weldment. In engineering, shipping, environmental protection, coal, agricultural machinery, food, boiler, pressure vessel and other industries, the butt welding elbow first uses CAD technology to design various diameters, and within 180 degrees, different materials are used for butt welding elbow and core and core. Manzhouli quality assurance of 8-shaped blind plate under pressure. The rib and lip play the role of strength and sealing respectively, which can not only seal by self tightening, but also strengthen the pipeline, and strengthen the overall strength of the connection part. Blind flange is a form of flange, it has no hole in the middle, which is mainly used to seal the hole of pipeline and equipment. It has the advantages of simple structure, easy processing and strong practicability.
