High-strength, corrosion-resistant GRP pipes manufactured via centrifugal casting for trenchless pipe jacking and microtunneling applications.
Utilizes an advanced centrifugal casting process to create a dense, void-free pipe wall for superior strength and durability.
Engineered with a smooth outer surface to minimize friction during pipe jacking, reducing installation forces and costs.
Offers exceptional resistance to corrosion from chemicals, sewage, and seawater, ensuring a long service life of over 50 years.
Lightweight construction (one-quarter the weight of ductile iron) simplifies transportation, handling, and on-site installation.
Features high stiffness ratings (SN2500 to SN1000000) to withstand high jacking forces and external soil loads without deformation.
Applicable for water supply, sewer drainage, industrial effluent, and seawater transport in direct bury, jacking, and relining projects.
