タイトルまたは説明

corrosion protection of oil,gas, petrochemical, waste water underground

and  overhead pipelines.the inner layer tape shall

be applied after the primer and before the outer layer tape .

gas pipeline joint wrapping tape with butyl rubber adhesive tape  is with a stabilized

polyethylene carrier film,coated on one sides with a permanently plastic synthetic

compound on a butyl rubber base.

The highly stable and supple carrier film guarantees a high degree

of protection from mechanical damage.

Structure: 

gas pipeline joint wrapping tape with butyl rubber adhesive tape consists of two layers:

 adhensive layer and film backing

 A:adhensive layer: butyl rubber

 B:film backing: special  blend of stabilized polyethylene
 

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.

 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.

 The inner wrap tape must be compatible with the properties

of the primer and the properties of outer wrap tape.

 PE backing colour shall be black.
 

gas transportation, petrochemical industry, electric power, metallurgy,

urban natural gas network of pipes, the outside anticorrosion project

of the metal pipes involved as well as the outside anticorrosion project

of the underground and overhead metallic conduit of the works

of petrochemical industry, natural gas and coal transportation.

 inner wrapping tape  safe and clean, performs well in insulation, anticorrosion,

mechanical strength and anticollision, moreover it is of low water absorption,

long service life, wide usage and convenient in application.
