Method for detecting leaks in steel lined PTFE pipelines
2025-03-17 14:21（Steel lined PTFE pipeline）Steel lined PTFE pipelines are a widely used anti-corrosion equipment in the chemical industry. However, many anti-corrosion pipeline manufacturers, due to their short construction time and lack of experience in inspecting plastic lined pipe fittings, have caused multiple points of damage to the anti-corrosion coating of pipelines and pipe fittings. Without inspection experience, some electric spark inspection instruments cannot detect leaks. （Steel lined PTFE pipeline）If the anti-corrosion coating is not long and damaged, steel lined PTFE pipelines may cause leakage incidents.（Steel lined PTFE pipeline）
Steel plastic composite pipes and fittings are the main damaged areas, and simple leakage areas include: straight pipe right angle flange, central long pipe, three connection pipe, and central elbow direction.（Steel lined PTFE pipeline）
The spark leak detection probe for household appliances in the existing production equipment does not meet the requirements for pipeline corrosion inspection. A simple leak inspection was conducted on the anti-corrosion layer of the steel lined PTFE pipeline. The probe is surrounded by stainless steel wire, with a nut connection point set at the center. （Steel lined PTFE pipeline）A 10mm round steel with a length of 3.5m is connected to the electric discharge machining probe. The circular probe slowly moves into the steel plastic composite pipe, and if there is any damage, it can be swept away regardless of size.（Steel lined PTFE pipeline）
Detailed manufacturing method: The steel lined PTFE pipeline is made of medium steel with a length of 500mm and a 20mm swinging spring. The head is surrounded by a spherical stainless steel wire, and the other end is welded with the same thread as the probe. （Steel lined PTFE pipeline）This probe can inspect three ends. During inspection, as long as the probe enters the steel lined PTFE pipeline, slowly move forward, actively turn, actively detect, and actively sound an alarm.（Steel lined PTFE pipeline）
