6061 6063 elbow marine aluminum
 
6061 6063 elbow marine aluminum In the piping system, the elbow is a pipe that changes the direction of the pipe. According to the angle, there are three most commonly used 45° and 90°180°, and other abnormal angle elbows such as 60° are also included according to engineering needs. Elbows are made of cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. The way to connect to the pipe is: direct welding (the most common way) flange connection, hot melt connection, fused connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, punching elbow, push elbow, casting elbow, butt weld elbow.
The bending radius is less than or equal to 1.5 times the diameter of the pipe belongs to the elbow, and 1.5 times larger than the pipe diameter belongs to the elbow.


 
1. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are all turned into bevels, leaving a certain angle with a certain edge. This requirement is also stricter, the thickness is too thick, the angle is how much and the deviation The scope has provisions. The surface quality and mechanical properties are basically the same as the tube. For the convenience of welding, the pipe is the same as the steel of the pipe to be connected.
2. All the pipe fittings must be surface treated, and the iron oxide skin on the inner and outer surfaces is sprayed off by shot peening, and then coated with anti-corrosive paint. This is for export needs, and in addition, in order to facilitate transportation and prevent corrosion and oxidation in the country, we must do this work.
3, is the requirements for packaging for small pipe fittings, such as exports, you need to do a wooden box, about 1 cubic meter, the number of elbows in this box is not more than one ton, the standard allows the suit, that is, a large set, However, the total weight can not exceed 1 ton. For large parts y, a single package is required, such as 24", it must be a single package. The other is the packaging mark, the mark is to indicate the size, steel number, batch number, manufacturer's trademark and so on.


 
6061 6063 elbow marine aluminum is a type of pipe used for turning a pipe. Among the total pipe fittings used in the piping system, the proportion is the largest, about 80%. Generally, different forming processes are selected for bends of different materials or wall thicknesses. The seamless elbow forming process commonly used in manufacturing plants has hot push, stamping, extrusion and the like.
Because the 6061 6063 elbow aluminum has good comprehensive performance, it is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire protection, electric power, aerospace, shipbuilding and other basic projects.
