System Description
The Maiqiang-930 is a cold applied tape coating system designed for the corrosion protection of field joints, fittings and specialty piping. The unique adhesive retains conformability over a wide temperature range, yet exhibits an elevated level of shear resistance, which is a key in-ground performance characteristic. Couple with a very malleable polyethylene backing, this versatile tape system can be applied by hand or with a wrapping machine.
