Changzhou mechanical processing manufacturer, let's talk about pipe fittings with everyone. When it comes to pipe fittings, we are not unfamiliar with them. In daily life, we often come into contact with them. Although pipe fittings have a very large scale of use, their performance in China is relatively poor. In Japan, whether it is samples or information introduction, there are many types of pipe fittings, and they are diverse. If we were to give a definition to pipe fittings, I believe that any product produced through deep processing of pipes should belong to the field of pipe fittings. Pipes are essential raw materials for pipe fittings, but there are many processing methods for pipe fittings, as long as they are mechanically processed, they can be used. Two prominent advantages of pipe fittings are that they can replace some machined products and are lighter in weight compared to machined parts, castings, and cast structural parts, saving materials; The second is to save processes and working hours compared to mechanical processing products, and reduce workpiece costs. A comparison has been made between a mechanical processing method for connecting rods used in trucks and a pipe fitting method in the Japanese data industry. The same product weight uses a different material weight. The mechanical processing method costs 0.35kg, while using pipe fittings to make this part costs 9.32kg, saving data; The unit price of machined parts is 240 yen, and if fittings are used, the unit price is 40 yen. So the pipe fitting method has a significant price advantage, reducing it by nearly 50%. In terms of performance, the pipe fitting method is superior to the mechanical processing method.
There are many types of pipe fittings, which can be summarized into the following primary types:
1. Variable diameter pipe fittings refer to the reduction in diameter of the pipe end or a certain part of the pipe;
2. Pipe fittings with variable wall thickness refer to those that change the wall thickness along the length direction of the pipe;
3. Modify the pipe fittings of the cross-section, and according to the requirements, transform the circular cross-section into squares, ellipses, polygons, etc;
4. Twisted pipe fittings, which we have a lot of contact with, are to transform straight pipes into bent pipes with different curvature radii, such as elbows, bends, etc;
5. Pipe fittings with flanges and circular edges. The former refers to the end of the pipe protruding inward or outward, while the latter refers to the pipe fittings that form arches or grooves in the circumferential direction of the pipe;
6. For pipe fittings with rolled edges and back covers, add pipe fittings with the total strength of the pipe end rolled towards the outer or inner side of the pipe or seal the end of the pipe fittings;
7. Expanding pipe fittings, expanding the ends or certain parts of the pipe fittings into various shapes according to requirements;
There are also many processing methods for pipe fittings. Many fields still belong to the category of mechanical processing, and the commonly used methods are stamping, forging, rolling, bulging, stretching, bending, and combination processing. Pipe fitting processing is an organic combination of machining and metal pressure processing.
The above is the knowledge and tools related to pipe fittings brought to you by Changzhou mechanical processing manufacturers, hoping to be helpful to you.
