Steel lined tetrafluoro pipeline is a kind of anticorrosive equipment which is widely used in chemical industry, but there are many anticorrosive pipeline manufacturers. Because of the short construction time and insufficient experience in production and inspection of plastic lined pipe fittings, there are many breakage points of anticorrosive coatings on pipeline fittings. In the absence of inspection experience, some EDM can not detect leakage at present. If the corrosion protection layer is damaged, the steel lined Teflon pipeline will leak.

Steel-plastic composite pipes and fittings are the main damaged parts. Simple leakage parts are right-angle flange of straight pipe, central long pipe, three-connection pipe and central elbow direction.

The spark leak detection probes for household appliances in existing production devices do not meet the requirements of pipeline internal corrosion inspection, and simple leak inspection for corrosion protection coating of steel lined tetrafluoro pipeline is carried out. The probe is surrounded by stainless steel wire, and the center of the probe is provided with a nut connection point. The length of the 10mm Round steel is 3.5m, which is connected to the EDM probe. The circular probe moves slowly into the steel-plastic composite pipe. If it is damaged, it can be swept away regardless of size.

Detailed manufacturing method: steel lined tetrafluoride pipe is medium steel 500 mm long, 20 mm swing spring, head is surrounded by spherical stainless steel wire, the other end is welded with the same threads as probe threads, the probe can check three ends. Inspection, as long as the probe into the steel lined Teflon pipeline, slowly forward, active steering, active detection, active alarm.

Generally speaking, a more desirable property in industrial applications is that the gasket material of steel lined tetrafluoro pipeline is capable of withstanding high compression load. Most gasket applications for industrial tetrafluoro pipes include bolts applied to compress to a range of 14 MPa or higher. Generally speaking, there are several cliches that better permit the performance of gaskets for tetrafluoro pipelines. One of the more attempts and tests is: "The more gaskets the compression load has on the tetrafluoro hose, the longer the time it takes, the longer it will last."

There are several ways to measure the capacity of a tetrafluoro pipeline gasket material to withstand compressive loads. The "hot compression test" may be one of the more acceptable tests. Most manufacturers of gasket materials for tetrafluoro hoses will provide or publish the results of these tests.

Washers are based on industrial use in many different designs, budgets, chemical contacts and physical parameters on the premise of simple, a material tetrafluoro hose gasket shape "perforation". This will result in a very rough, fast and inexpensive gasket for tetrafluoro hoses. In previous sub-compressed asbestos materials, but in modern fibre materials such as high temporary use of graphite. These tetrafluoro hose gaskets can fill many chemical requirements based on inert materials, suitable for many budget constraints. Common practices can prevent these washers from being used in many industrial processes based on temperature and pressure concerns.
