About the joint production process

Joints are components connecting two pipes or pipes and valves, accessories, etc. They are usually required to be used in large quantities during the construction and maintenance of piping systems, and have a wide range of applications and important roles. The process of joint production generally includes material preparation, preparation, molding, processing, inspection and packaging and so on.

I. Material preparation
The main materials of joints are cast iron, steel, stainless steel, copper, aluminum and other metal materials, according to different uses and environmental conditions, the choice of materials for joints is also different. In the joint production process, the first thing that needs to be done is the material preparation work. This work includes selecting suitable raw materials and confirming the specification, type and quantity of materials. At the same time, it is also necessary to carry out quality testing of the material to ensure that the material meets the relevant standards and requirements.

Second, the preparation
Joints are often prepared using casting, forging, stamping and other processes. Among them, casting is the most commonly used process in the production of joints. Casting can be divided into sand casting, precision casting, die casting, pouring and other ways. In the casting process, you need to first prepare the relevant mold. The mold production process is generally divided into design, drawing, production, assembly and other steps. Nowadays, the application of computer-aided design software greatly improves the precision and efficiency of the mold. The next step is the preparation of the molten casting material, the molten metal is poured into the mold, and the joint is formed after cooling.

Third, molding
Before molding, relevant heating treatment and pretreatment are needed. This is to make the material more malleable and easy to form. In the forming process, the shape, size and surface of the joint need to be processed and shaped using the appropriate molding machines and tools. The production of some joints also requires special forms of processing such as opening, punching, slot processing, gear processing and so on.

Fourth, machining
The steps of processing generally include turning, grinding, polishing and so on. Among them, the turning process is a very important processing method. Lathe for the production of joints is very necessary equipment, it can realize a variety of shapes and sizes of workpiece processing. The working principle of lathe is to let the workpiece cut with the tool under rotation, so as to realize the purpose of machining. In the grinding and polishing process, it is necessary to use the corresponding abrasives and sandpaper and other materials to further improve the quality and surface finish of the joints.

V. Inspection
After the completion of the production of the joint, a comprehensive quality inspection is required. First of all, you need to check whether the size, shape and appearance of the joints are in line with the relevant standards and technical requirements. Secondly, it is also necessary to carry out sealing, strength, corrosion resistance and other aspects of the test. This work requires a series of tests and inspections, using the appropriate test equipment and instruments for testing and measurement.

Sixth, packaging
In the last step of the production process of the joint, is the corresponding packaging of the joint. Packaging is to protect the joints, in the transportation and storage process will not be damaged. In general, use plastic bags, wooden boxes, cardboard boxes and other packaging materials, according to the shape and number of joints for the corresponding packaging and packing. At the same time, it is necessary to mark the name, model, quantity and other information of the product on the box to facilitate user identification and management.

The above is the basic link of the production process of joints, each link is very important. Only in strict accordance with the above workflow to carry out production, in order to ensure the quality and stability of the joint products.
