G10 epoxy pipe is made of electrical alkali-free glass fiber cloth impregnated with epoxy resin, baked and processed by hot pressing in a molding die. The cross-section is round. The glass cloth rod has high mechanical properties. It is suitable for insulating structural parts in electrical equipment, and can be used in wet environmental conditions and transformer oil.

The use of G10 epoxy pipe:

Before using the pipe, it is necessary to check and check whether the size of the official material and the cable are consistent, and then choose a more suitable environment for construction. Good, this is more important.

Secondly, in use, the entire process of the construction workers' operation should be completed as directly as possible. In addition, after the construction of the G10 epoxy pipe, remember to clean up the construction site and keep the exterior of the pipe clean.

Details to be paid attention to when testing G10 epoxy pipe:

Inspection method Appearance inspection and visual inspection to inspect the appearance quality of the coated steel pipe. For thickness measurement, take two cross-sections of different lengths from both ends of the coated steel pipe, and use an electromagnetic thickness gauge on each cross-section to measure the coating at any four points orthogonal to the circumference. Layer thickness, the experimental results should meet the requirements of 5.4. The length of the pipe section in the pinhole test is about 1000 mm, and the coating of the steel pipe is checked under the specified experimental voltage with an electric spark leak detector. The coating thickness is not greater than 0.4 mm, the test voltage is 1500 V, and the coating thickness is greater than 0.4 mm , the experimental voltage is 2000 V.

Check whether there is an electric spark, and the experimental results should meet the requirements of 5.5. Adhesion test Adhesion test is carried out in accordance with 7.4.2 of CJ/T 120-2008, and the test results should meet the requirements of 5.6. Bending test Coated steel pipes with DN ≤ 50mm were subjected to bending experiments. The length of the pipe section test piece is (1200±100) mm. Under the temperature of (20±5)℃, the radius of curvature is 8 times the nominal diameter of the steel pipe, and the bending point of view is 30o, and the bending is carried out on the pipe bender or mold. During the zigzag test, there is no filler in the tube, and the weld is located on the side of the main surface of the zigzag. After the experiment, cut the specimen from the middle of the zigzag arc to check the inner coating. The experimental results should meet the requirements of 5.7. Flattening test Coated steel pipes with DN>50 mm were subjected to flattening test.
