US Composite Pipe South Jacking Pipe

Microtunneling/Jacking

Due to the ultra-high compressive strength of the polymer concrete (minimum of 13,000 psi); Polycrete pipe, even with thinner walls than traditional concrete jacking pipes, can safely withstand higher jacking loads. Polycrete’s tight dimensional tolerances and smooth, non-porous exterior, combined with high compressive strength, make Polycrete the preferred pipe for demanding jacking applications.

Jack and Bore

Just as conventional concrete pipe is used for highway and railroad crossings, Polycrete jacking pipe is also suitable in this application, with the added benefit that steel casing is not required. Such installations are currently in service and per-forming successfully underneath railroads and interstate highways in the United States and Canada.

FEATURES	BENEFITS
Corrosion Resistant Material	• Resists ph 1.0 to 10, projected 100 year plus service life • No need for linings, coatings, cathodic protection, wraps, or other corrosion protection • Low maintenance costs • Hydraulic characteristics essentially constant over time
Superior Strength Attributes	• High Compressive Strength – (minimum 13,000 psi) • Higher Jacking forces for longer drives & higher tolerance for start-ups • Strength Classes with corresponding D-loads
Excellent Hydraulic Characteristics	• Extremely Smooth Bore • 0.009 Manning’s “n” flow coefficient • Low friction loss, high flow rates • Minimal slime build-up means lower cleaning costs • Excellent abrasion resistance
Superior Jointing System	• Water tight up to 35 psi • Tight, efficient joints designed to eliminate infiltration or exfiltration • Ease of joining, reduces installation time
Advanced Technology Pipe Design	• Complies with stringent performance standards: ASTM, DIN. • High and consistent product quality worldwide which ensures reliable product performance
Microtunneling Advantages	• High Dimensional Accuracy – No ovality, tight joints stay tight, follows shield • Parallel (Square) Pipe Ends for straighter drives, uniform distribution of jacking forces • Steel Guide Collar – Maximum durability during jacking • Reduced point loading and risk of local rupture • Smooth, Even, Non-Porous Outer Pipe Surface - Reduced skin friction and start-up jacking loads even after long stoppages
