Indus Industrial Group supplies specialized GRP Microtunneling & Pipe Jacking Pipes engineered in nominal diameters from DN500 (20") to DN2400 (96") designed for trenchless pipeline crossings beneath highways, railways, airport runways, and urban canal crossings across Iraq. Manufactured by centrifugal casting or high-density cross-filament winding, these jacking pipes feature precision-machined flush joint ends with recessed stainless steel collars and high compressive axial load ratings capable of withstanding hundreds of tons of hydraulic jacking thrust from microtunnel boring machines (MTBM).

Trenchless microtunneling beneath Baghdad expressway interchanges, Erbil ring road crossings, railway track crossings, canal crossings, and urban utility tunnel drives across Baghdad, Erbil, Basra, and Kirkuk.
Urban infrastructure expansion across major Iraqi cities like Baghdad, Erbil, and Basra frequently requires crossing major expressways, active railway lines, oil pipelines, and international airport perimeters where open trenching is strictly prohibited by civil authorities. GRP Microtunneling Pipes provide an engineered trenchless solution that combines extraordinary axial compressive strength (up to 90–120 MPa) with a completely smooth, cylindrical outer surface that minimizes skin friction against surrounding soil during boring.
Conforming to ISO 25780 and DIN 54815-1 standards for trenchless jacking pipes, each pipe length is manufactured with dimensional precision: square-cut ends, zero wall thickness variation, and flush external profile. The flush-joint coupling utilizes a recessed 316 stainless steel or GRP sleeve with integrated EPDM lip seals and wood/polymer pressure-distributing packing rings, ensuring uniform axial load transmission across the pipe face without point-load stress concentrations.
The high ring stiffness (SN20000 to SN64000) guarantees zero structural deformation under overburden earth pressure and heavy live traffic loads above. Staged with companion intermediate jacking stations (IJS) and certified jacking load calculation tables at Indus regional yards in Erbil and Baghdad.
GRP jacking pipes have a much thinner wall while maintaining equal or higher strength, meaning smaller tunnel bore diameter, 40% lower skin friction, longer jacking drives between thrust pits, and 100% immunity to sewer acid corrosion.
A precision-machined wooden or elastomeric packing ring is placed on the spigot face of every joint. This packing ring crushes slightly under thrust to distribute hydraulic jacking forces uniformly across 100% of the pipe circumference.
Yes. We supply GRP jacking pipes rated for both gravity sewer flow and internal pressurized service up to PN16 with pressure-tested flush elastomeric joints.
