Product Overviews

 

Applications and Characteristics:

The PP anti-corrosion adhesive tape of our company is produced by taking high-strength polypropylene fabric as the base material and coating with a certain thickness of high viscosity rubber modified asphalt through special process. Its excellent tensile strength and adhesion properties contribute to effective resisting the stress and thermal expansion of the earth and preventing the deformation of the corrosion layer. A single layer of such tape realizes the reinforced anti-corrosion standard. This type of tape is a patent technology invented specific to the negative protection requirements on long-distance pipelines and municipal pipelines. It use the most cutting-edge technology in international and domestic anti-corrosion tape. The network fiber structure does not hinder the negative protection current, so that the anti-corrosion coating will not produce negative shielding. Therefore, it is applicable to negative protection of pipelines.

 

Application Method:

(1) Remove rust, weld, burr, oil stains, and dry. Manual rust removal shall reach level St3. Mechanical rust removal shall conform to level Sa2 as stipulated in SYJ 4007-86. After rust removal, the defects on the steel pipe surface should be treated. The dust and abrasives attached to the surface should be cleaned up. The surface of the steel pipe should be kept dry. In case of re-rust or surface contamination, surface pretreatment must be carried out once more.

(2) The time interval between pretreatment of primer (manual or mechanical) steel pipe surface and painting primer should be controlled within 6 hours. The surface of steel pipe must be dry and dust-free. Stir the primer evenly in the container. If the primer is too viscous, add the diluent matched with the primer to a proper viscosity before construction. Apply the primer with a clean brush, roller or by other mechanical methods. The primer coated on steel pipes should be free of defects such as leakage, bubbles, clots and sagging, and shall form uniform film. The primer thickness should be greater than or equal to 30 microns. The weld should be carefully brushed to avoid missing.
