Extena liner pipes/blast pipes are used for blasting mountains. The pipes are prepared with the blast charge, inserted into the drilled charge holes and ensure that the charge is in the correct position. One end is fitted with a plug to prevent the explosive from leaking out. The blast pipes are made of polypropylene, an impact resistant and rigid material, which means that we can offer thin pipes with high ring stiffness. Our liner pipes/blast pipes are available in dimensions between Ø 37–46.

Material specification
The liner pipes are made of polypropylene (PP).

Environment
Polypropylene is a 100% recyclable material. The material can be regranulated and reused for the manufacture of a variety of products.
