Pipeline Repair Tape
Product Description
System Description
The Qiangke Pipeline repair tape can be applied for emergency leakage repair when the piping is depressurized.
Qiangke Pipeline repair tape is a cold applied tape coating system designed for the corrosion protection of field joints, fittings, and specialty piping.
The unique butyl rubber adhesive retains conformability over a wide temperature range, yet exhibits an elevated level of shear resistance, which is a key in-ground performance characteristic.
Coupled with a pliable, very malleable polyethylene backing, this versatile pipe repair tape system can be applied by hand or with a wrapping machine.
Features
● Cold applied
● Complies with ASTMD 1000,AWWA C 214&209.
● Reliable, high-performance corrosion protection.
● Compatible with generic plant coating systems.
● Compatible with PE,FBE,TAPE &COAL TAR coatings.
Composition
The composition of the pipe wrap tape - repair tape consists of two layers, butyl rubber adhesive layer and film backing.
