Product Details

Patching Piece

Patching Piece is an anti-corrosion coating material especially for the anti-corrosion and repair of the welded joint of buried of overhead steel pipe.It has excellent tensile strength and bonding performance and can protect the pipe from the soil stress. The impact of the external force and thermal expansion which prevents deformation and stripping of the anti-corrosion layer and greatly extends the life of the protected body.
