Design of GRP Pipes and Fittings
KTI Engineering department are fully equipped for designing the GRP pipes and fittings system suited for Underground and Above ground applications as per ISO 14692, AWWA M45, AWWA 950, API 15 LR & HR, Shell or any other customer specified standard.
Comprehensive GRP Pipe Engineering
Glass Reinforced Plastic (GRP) piping systems offer exceptional corrosion resistance, lightweight construction, and long service life. KTI's engineering team brings decades of expertise in designing GRP systems for oil & gas, water treatment, industrial, and infrastructure projects worldwide. From initial concept through detailed design, we deliver solutions that are both technically sound and economically optimized.


U/G Pipe Design & Structural Calculations
Underground pipe design calculations cover live and dead load effects on the pipe in addition to the effect of internal pressure and vacuum pressure on the adequacy of pipe for buckling, combined strain, and allowable stress as per AWWA M-45 and C-950.
- Live and dead load analysis
- Internal pressure and vacuum pressure effects
- Buckling and combined strain checks
- Compliance with AWWA M-45 and C-950

Above Ground GRP Piping Systems
Our engineering team ensures that every above-ground design meets international standards and client specifications, providing reliable and cost-effective solutions. We evaluate thermal expansion, support spacing, and wind/seismic loads for complete system integrity.
- Thermal expansion and contraction analysis
- Optimized support spacing design
- Wind and seismic load evaluation
- ISO 14692 and API 15 LR/HR compliance

International Standards Adherence
KTI designs GRP pipes and fittings in full compliance with globally recognized standards. Our designs are validated against ISO 14692, AWWA M45, AWWA 950, API 15 LR & HR, Shell DEP, and any other customer-specified standard or specification.
- ISO 14692 — GRP piping systems
- AWWA M45 / C950 — Fiberglass pipe design
- API 15 LR & HR — Low and high pressure GRP
- Shell DEP and custom client specifications
