3ply Inner inner Tape (T100) for water pipeline for hydran
3ply Inner defines the requirements and tests for Tape used for Coating over the ditch and repair coating of buried steel line pipes using cold applied Polyethylene tape. All tapes shall be designed and manufactured for a continuous working temperature of up to 50o C.
2. DESCRIPTION OF THE COATING SYSTEM:
2.1 The coating & wrapping system as defined by this specification is a Three Part System, made up to the following parts for either hand or machine application:
2.1.1 3ply Inner tape
This part consists of two components:
i) Adhesive : Inner layer of butyl rubber.
ii) Backing : Outer layer of Polyethylene (PE) plastic.
2.1.2 TAPE-OUTER:
This part consists of two components:
i) Adhesive : Inner layer of butyl rubber.
ii) Backing : Outer layer of Polyethylene (PE) plastic
3. MATERIAL SPECIFICATION:
3.1 Tape 3ply Inner Wrap
3.1.1 The inner wrap tape shall be two ply plastic tape consisting of stabilized polyethylene (PE) base of outer layer (backing) with a layer of butyl rubber (adhesive) applied on one side.
3.1.2 The thickness of plastic base shall not be less than 13mils. Thickness of butyl rubber shall not be less than 12 mils. The total thickness of the tape shall not be less than 25 mils.
3.1.3 The inner wrap tape must be compatible with the properties of the primer and the properties of outer wrap tape.
3.1.4 PE backing colour shall be black.
