Installation of new pipes up to 315 mm in diameter at the distance of up to 150 m
Trenchless replacement of old pipelines up to 315 mm in diameter by means of static pipe bursting
Distinctive features
The MNB-50 unit’s principal competitive advantage is its wide range of functions. Minimal excavations for pits, with the minimal disruption of surrounding areas, make the MNB-50 unit particularly useful in confined urban conditions.
MNB-50 works reliably under severe winter conditions in Russia, Belarus, Ukraine and Kazakhstan. MNB-50 is the most popular unit in its class due to its good combination of price, versatility, scope of applications and small size.
Options for the MNB-50 unit installation and operation:
-from the pit (3 m long, 1 m wide);
-from OR-1,5, the formwork manufactured by MEMPEX JSC (2,5 m long, 2 m wide);
-from the existing well (Ø 1500 mm).
No bentonite mixtures required.
