6) Length: 30 - 300m
1.2 Outer wrapping adhesive tape:
(Protection Tape, Protective Tape,Mechanical tape ) is for protection of pipe and the surface of Inner Tape from damages.
?
Features:
1) The specification of the tape consists of two layers, adhesive and film
2) Inner layer: butyl rubber
3) Outer layer: polyethylene
4) Thickness: 0.40 - 1.30mm
