PipeWrap BT is a hot applied corrosion protection bituminous tape conforming to IS 10221 Appendix B specification. It comes in two thicknesses: 2 mm & 4 mm. The 4 mm thick pipewrap-BT is a 4 ply tape with two inner cores. The top core is of though 45 gsm fiber glass and the bottom core is of the micron high tensile strength HMHDPE. The 2 mm PipeWrap BT is a 3 ply tape without the fiber glass inner core. The specially formulated corrosion resistant bitumen compound provides high softening point, high penetration and high resistance to ageing. The tape comprises of high tensile strength thermofusible HMHDPE film on both the sides.
PipeWrap BT is designed for application on buried and immersed pipes, fittings and appurtenances, to protect them from high corrosive environment. For application on steel substrates and steel fittings, a coat of shalitex primer (FD) is required.
