Principle:

During the connection process of two pipelines, the conical structure of the pipe threads creates a certain gap at the interface. When the external and internal threads of two pipelines match each other, they form a tight fit, thereby achieving a sealing effect. This sealing effect mainly depends on the friction between metals. ‌

Applications:

1.Industrial pipeline system: The design of the joints is compact, the structure is simple, and the installation is easy, which can quickly connect the pipelines and ensure the efficient operation of industrial production. ‌

2.Petroleum and chemical industry: In underground oil pumps, pipelines, and valves, straight through variable diameter external thread sealing joints are used for connection and sealing, ensuring the safe transportation and handling of petroleum and chemical products. ‌

3.Compressed air system: In the compressed air system, these joints are used to connect compressed air pipelines, air filters, air dryers and other equipment and components, ensuring the normal operation of the compressed air system. ‌

4.Special industry applications: Straight through variable diameter external thread sealed joints are also used for branch connections in various pipeline systems in industries such as semiconductors, photovoltaics, LEDs, optical fibers, pharmaceuticals, environmental engineering, electroplating, food, ultrapure water, and chemical systems.
