Twin wall boom pipes have an inner resistant pipe lining with an outer steel shell. The internal liner is made of special anti-wear steel, hardness up to HRC68. The induction hardening process and high-quality welding process ensure that pipes achieve a service life that is several times longer than common ST52 pipes with the same wall thickness.
