Other advantages High dimension precision- no oval, close connection and maintenance tracking;Parallel pipe ends in straight-line distance, jacking force is evenly distributed;Steel sleeve- permanent endurance during jacking; Less risk relating to point load and partial fracture; Smooth, flat and un-perforated pipeline external surface- reduced surface friction and transient load at the time of startup after long-time interruption

Excellent water pressure characteristics Smooth inner wall; Manning discharge coefficient (n) 0.009; Less frictional loss and higher flow; Least clay accumulation and lower cleaning expense; Excellent abrasion resistance

High-strength High pressure resistance (not less than 80Mpa); Possible to cope with long-distance and complex terrain with higher jacking force

Excellent connection system Water tightness up to 2.5kg/cm2; Tight and highly efficient connection, free from leakage; Convenient connection and reduced installation time.

Advanced pipeline design technology High-performance standard: ASTM, DIN Consistent high quality and product performance around the world

Corrosion-resistant material Corrosion resistant ph1.0—10, expected service life up to 100 years; No need for liner, external protection layer, cathode anticorrosion or other anti-corrosion protection; Lower maintenance cost; Water pressure characteristics is basically constant, independent from time change.
