It is obviously important for the use of grooved pipe fittings and the correctness of the mold, and the premise and basis of these is the correctness and proper maintenance of the mold mold. To do anything, safety issues must be put in the first place, and for trench pipe fittings, mold repair, maintenance is to deal with mold, equipment (steel), this problem must be attached great importance; Grooved pipe fittings 1, the use of the ring must be checked first to ensure that it is intact; 2, the use of equipment, especially the production of flying debris, must be operated with glasses; 3, welding must wear protective clothing, with protective glasses; 4, it is strictly prohibited to work on the bottom of the mold; 5, the machine operation, must ensure that the injection molding machine in the stopped state, and hang up the sign.

Grooved pipe fittings flange is also called flange flange disc or flange. The flange is a part connected between the pipe and the pipe, which is used for the connection between the pipe ends; It is also useful in the flange on the import and export of the equipment for the connection between two devices, such as the reducer flange. Flange connection or flange joint refers to a detachable connection which is connected by flanges, gaskets and bolts as a group of combined sealing structures. Pipe flange refers to the flange of the pipe distribution pipe in the pipeline device, used in the equipment refers to the import and export flange of the equipment. A hole bolt is arranged on the flange of the grooved pipe fitting to make the two flanges tightly connected. The flange is sealed with a gasket. Flanges are divided into threaded connection (thread connection) flanges, welded flanges and clamp flanges. Flanges are used in pairs, wire flanges can be used for low pressure pipes, and welded flanges for more than four kilograms of pressure. Put a gasket between the two flanges and fasten them with bolts. Different pressure flange thickness is different, they use different bolts. Pumps and valves, when connected with pipelines, the local parts of these equipment are also made into corresponding flange shapes, also known as flange connections. All the connecting parts that are connected by bolts around two planes and are closed at the same time are generally called "groove pipe flange", such as the connection of ventilation pipes, this type of part can be called "flange class parts". But this connection is only a part of the equipment, such as the connection of the flange and the pump, it is not good to call the pump "flange parts". Relatively small such as valves, etc., can be called "flange parts".

There are many kinds of grooved pipe fittings, and the specification series is also not a win, but the real use is the largest, the most effective is so few, and in the few main product series, the reducing pipe is one of the important molecular components, perhaps you often use him, but how much do you know about him? It doesn't matter, not knowing in the past does not mean that you do not know in the future, the following will take you to analyze the mystery. Reducing pipe, also known as large and small head, mainly refers to the use of pipe diameter reduction. The main function of reducing pipe is to achieve a transition from large to small pipe diameter in the water supply trench pipe fitting, and the quality of reducing pipe should meet the current national standard "steel butt welded seamless pipe fitting" GB/T 12459-2005.

Sometimes we also call it a pipe link pipe, so what is the reason to give it such a unique or industry name? In fact, there are certain reasons in it, which in fact has fully explained the importance of the groove fittings in the pipeline connection. In our modern construction of pipeline connections, we have basically used grooved pipe fittings. The main reason is that when the groove fittings are used, a groove is extruded by a rolling groove machine only on the outer surface of the connected pipe without damaging the inner wall structure of the pipe, which is the unique technical advantage of the groove fittings connection. Compared with the traditional welding connection method, the first is simple operation, the second is smooth and good-looking appearance, the third has been done with anti-corrosion treatment, and the fourth is not limited by the technical operation of workers. These reasons and reasons are enough to prove the importance and status of the grooved pipe fittings in the pipeline connection.
