3PE anti-corrosion pipelines
3PE anti-corrosion is a kind of anti-corrosion outside the pipeline. 3PE anti-corrosion steel pipe has a high tightness. Long-term operation can greatly save energy, reduce costs and protect the environment. Every link in the anti-corrosion process should be tested according to standards.First: check oil, steel pipe pits, layers, weld shape and height defects on the surface of the bare pipe
Second: After derusting, check the depth of the anchor pattern (you can see the shape of the anchor pattern more finely) (Sa2.5)
Third: After the 3PE corrosion test is completed: EDM leak detection, peel strength (60 ° C and room temperature), FBE thickness, total thickness of corrosion layer; cathode peeling in laboratory for 30 days and 24 hours, indentation strength, flexural strength, Soak for 1000 hours.
Fourth: The discharge detector can be used in the discharge detection. This equipment uses the principle of digital circuit control and pulse generation. The unique one-touch switch automatically enters the charging state when charging. The digital circuit structure makes the displayed value more stable, and the detection of high-voltage pulses is more stable. The aluminum alloy casing makes the machine more beautiful and durable.
Fifth: If the pipeline repair port is required to be corroded, heat shrinkable tape can be used. The anticorrosion of the segments is as follows.
