Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipes, in particular to a stainless steel pipe fitting connection device. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strengths are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also commonly used as furniture and kitchenware. The inner diameter of the stainless steel pipe is above 6.0mm and the wall thickness is below 13mm. The annealed stainless steel pipe can be tested with the W-B75 Webster hardness tester, which is very fast and simple to test, and is suitable for fast and non-destructive qualified inspection of stainless steel pipes. For stainless steel pipes with an inner diameter greater than 30mm and a wall thickness greater than 1.2mm, the Rockwell hardness tester is used to test the HRB and HRC hardness. For stainless steel pipes with an inner diameter greater than 30mm and a wall thickness less than 1.2mm, the surface Rockwell hardness tester is used to test the HRT or HRN hardness. For stainless steel pipes with an inner diameter less than 0mm and a wall thickness less than 4.8mm, the Rockwell hardness tester dedicated to pipes is used to test the HR15T hardness. When the inner diameter of the stainless steel pipe is greater than 26mm, the hardness of the inner wall of the pipe can also be tested with a Rockwell or surface Rockwell hardness tester. Stainless steel exports are an important part of my country's export economy. It plays an important role in driving my country's economic growth. However, judging from the current situation of my country's stainless steel foreign trade, my country's stainless steel exports have encountered great resistance.

[0003] The application number is CN202022869906.0, which discloses a connection device for compression of stainless steel pipe fittings, including a compression joint and a connecting pipe, a ring groove is provided on the inner side of the compression joint, the cross section of the ring groove is U-shaped and a sealing ring is fixed on the inner side thereof, and the center line of the sealing ring coincides with the center line of the compression joint; the end of the compression joint away from the ring groove can extend into the inner side of the connecting pipe, and the end of the compression joint extending into the inner side of the connecting pipe is provided with a mounting portion, and the mounting portion is stepped; a limiting portion cooperating with the mounting portion is provided on the inner side of the connecting pipe, and the end of the compression joint is installed and limited at the limiting portion of the connecting pipe through the mounting portion, and a plurality of elastic sealing rings with different inner diameters are provided on the inner side of the connecting pipe and the connecting end of the compression joint, and the inner diameters of the plurality of elastic sealing rings decrease successively from the side away from the connecting pipe to the side close to the connecting pipe. The compression joint of the utility model is installed on the inner side of the end of the connecting pipe through the cooperation of the mounting portion and the limiting portion, and has the advantage of simple assembly.

[0004] Although the above-mentioned utility model is installed on the inner side of the end of the connecting pipe through the cooperation of the installation part and the limiting part, and has the advantage of easy assembly, it has the disadvantage that when the device is used after the connection, its internal part has not been optimized for the transmission properties of the pipeline connection, so that leakage and other problems may occur during use.
