Product description:
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:
TAPE-INNER:
This part consists of two components:
i) Adhesive : Inner layer of butyl rubber.
ii) Backing : Outer layer of Polyethylene (PE) plastic.
TAPE-OUTER:
This part consists of two components as in inner wrap tape i.e.
i) Adhesive : Inner layer of butyl rubber.
ii) Backing : Outer layer of Polyethylene (PE) plastic.
PRIMER:
A viscous liquid of petroleum spirit base compatible with the above Inner and Outer Wraps applied directly on pipes.
3. MATERIAL SPECIFICATION:
3.1 Tape 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.
TAPE-OUTER WRAP:
3.2.1 The Outer Wrap Tape shall be two-ply plastic tape consisting of stabilized polyethylene base of outer layer (backing) with a layer of butyl rubber (adhesive) applied on one side.
3.2.2 The thickness of the butyl rubber layer shall not be less than 5 mils. The total thickness of the tape shall not be less than 25 mils.
PE backing colour shall be White.
3.3 PRIMER:
The primer shall consist of butyl rubber and unsaponifiable resins in petroleum spirit and it shall be compatible with the butyl adhesive that is furnished on the inner wrap tapes, must be free flowing, and have the ability to cover voids, pits and welds. The primer must provide an acceptable base for butyl adhesive on the tapes.
