Bituminous-Butyl Rubber Tapes

«QIAO PAI T-1160» CORROSION PROTECTION TAPE

«QIAO PAI T-1160» CORROSION PROTECTION TAPE

The product is designed for corrosion protection of the outer surface of the steel oil and gas trunk pipelines, product pipelines with a diameter of up to 1220 mm inclusive in their construction and repair.

«Qiao Pai T-1160» tape is a self-adhesive roll material. The tape consists of a base of a special blend of stabilized polyethylene and adhesive layer of bitumen-butyl rubber mastic with the addition of some resins.

The tape is protected by a release film preventing the tape turns in the roll from sticking. The tape is UV resistant.

«Qiao Pai P-27» primer-adhesive comes with the tape.

«Qiao Pai P-27» primer-adhesive is a black homogeneous liquid composition of butyl rubber, adhesive resins and solvents.

APPLICATION

«Qiao Pai T-1160» Tape is intended for mechanical (by coating-and-wrapping machines, devices) and manual application onto the surface of the pipeline, at an ambient temperature of -25 °С to +70 °С.

According to its physical & mechanical and protective properties «Qiao Pai T-1160» tape corresponds to «В» Class — a very enhanced coating according to the National standard of Ukraine State Standard 4219-2003.

According to thermal stability, depending on the maximum operating temperature, «Qiao Pai T-1160» tape is stable at pipeline temperature up to +70 °C.

In terms of resistance to the special operating conditions, the «Qiao Pai T-1160» tape corresponds to the «UV» class of the coating as suitable for use over an extended action of ultraviolet radiation.
