Description

Integrated welding-free flange

Technical Field

The utility model belongs to the technical field of flanges, and particularly relates to an integrated welding-free flange.

Background

The flange connector generally used on the rotational molding plastic container barrel aims at resisting acid, alkali and corrosion and is easy to be connected with another flange. The installation method is that a hole with the same size is formed on the barrel, then the tail part of the flange is installed in, a plurality of circles are welded by welding bars from the outside of the barrel body, and then the flange is climbed into the barrel to be welded for a plurality of circles, so that the flange can be firmly fixed. The welding device has the defects that the welding device can pollute the environment in the welding process, and the welding part can be cracked to cause the liquid leakage phenomenon due to the fact that the phenomenon of collision can not be avoided in the transportation and installation processes. Most of barrels connected by flange are filled with chemical substances, such as sulfuric acid, caustic soda, sodium hydrosulfite, hydrochloric acid and other toxic liquids, and leakage occurs after the barrels are used for several years, or a plurality of flanges are additionally arranged at certain positions according to actual requirements, so that an installation master climbs into the barrels to be welded, and toxic gases generated by heating possibly cause injury to human bodies to a certain extent. The flange connection mode which circulates for over twenty years is installed in the way, and most importantly, the barrel filled with chemical substances has the phenomenon of liquid leakage after being used for a period of time, and the maintenance is very difficult. Because many flanges are installed at the bottommost part of the barrel body, the phenomenon of liquid leakage occurs after the barrel body is used for a period of time, all connecting pieces on the barrel body are required to be removed when the liquid leakage part of the flange is repaired again, and the bottommost part can be welded after the barrel is placed down. The maintenance cost is very high. In addition, once leakage occurs from the welding part, the pollution of chemical substances to the surrounding environment is serious, and in order to solve the problems, an integral welding-free flange is provided.
