Installation Instructions

1. Surface treatment

The surface rust of pipe body is removed by mechanical rust removal equipment (electric angle mill), and the derusting grade reaches ST2. After rust removal, the surface of the pipe body is dried by a heat blower.

2. Pipe body wrapped with viscoelastic anti-corrosion tape

Wrap a layer of viscoelastic anti-corrosion tape around the pipe section which has finished surface treatment, and the lap length between the end and the original coating shall not be less than 50mm. The minimum lap length of the joint of anti-corrosion tape is 10 mm. When wrapping the viscoelastic anti-corrosion tape, it is unnecessary to maintain a large tension, and press the edge and overlapping part of the tape by hand.

3. Flange and other special-shaped parts wrapped with viscoelastic anti-corrosion tape

For the anti-corrosion operation at the connection of valve flange, the connecting bolt can be filled with anti-corrosion paste and coated with viscoelastic anti-corrosion tape.

4. Wrapping outer protective tape

The basic operation method is the same as that of viscoelastic anti-corrosion tape, but the tension shall be maintained when wrapping the outer protective tape. The overlapping amount of joint part is 50%. The two ends of the anticorrosive pipe section shall be exposed 1-2mm respectively, and the outer protective tape shall not be wrapped.

5. Quality inspection

The quality requirements for installation of viscoelastic anti-corrosion tape and outer protective tape: the surface is flat, overlapping is even, and there is no bubble, wrinkle and damage.
