Industrial FRP GRP Products Manufacturer

Industrial GRP Product Portfolio of a Leading FRP/GRP Solutions Manufacturer

Yingnai engineers FRP Pipes, FRP Tanks, FRP Scrubbers, FRP Electrolytic Cells, FRP Pipe Fittings, and FRP Pultruded Profiles for corrosion resistance, process compatibility, structural reliability, and lower maintenance.

Custom FRP/GRP Solutions Designed for Your Project

From material compatibility to structural performance, Yingnai turns your operating data into a fit-for-purpose FRP/GRP solution engineered for reliable, long-term service.

We evaluate the process medium, chemical concentration, temperature, pressure, structural loads, installation conditions, dimensions, and applicable project standards.

Operating Requirements Review

Our engineers select the resin system, reinforcement materials, corrosion barrier, and laminate structure, then verify strength, thickness, and critical details through engineering calculations and FEA when required.

Material and Structural Engineering

Dimensions, shapes, pressure ratings, nozzles, flanges, supports, internals, and installation interfaces are customized to match your process layout and connected equipment.

Product and Interface Customization

The appropriate manufacturing process is selected for each product, including filament winding, hand lay-up, and vacuum infusion, with strict control of raw materials, production procedures, and key process parameters.

Production & Manufacturing

Critical dimensions, laminate quality, appearance, mechanical performance, and leak tightness are inspected before delivery, supported by technical documentation, installation guidance, and responsive after-sales service.

Inspection and Technical Support

FRP/GRP Solutions Across Critical Global Industries

Yingnai develops FRP/GRP systems suited to specific working conditions by matching structural design, manufacturing methods and quality controls to different industrial environments.

FRP tanks, pipes, fittings, and scrubbers are used for chemical storage, transfer, processing, and exhaust treatment, helping prevent corrosion and leakage while reducing maintenance and replacement costs.

Chemical Processing

FRP pipes, tanks, and fittings are used in slurry transport, leaching, extraction, and chemical dosing systems, helping resist corrosion and abrasion while reducing equipment replacement and production downtime.

Mineral Processing

Durable FRP pipes, tanks, gratings, and structural profiles reduce corrosion and maintenance in water networks, wastewater facilities, pumping stations, and public infrastructure.

Municipal Infrastructure

FRP pipes, tanks, and fittings are used in wastewater treatment, chemical dosing, seawater desalination, and brine handling systems, helping prevent chloride corrosion and leakage while maintaining reliable water treatment operations.

Water Treatment

FRP scrubbers, absorption towers, ducts, and chimneys are used for acid mist and corrosive exhaust treatment, helping maintain treatment efficiency, prevent corrosion damage, and extend equipment service life.

Air Treatment

FRP tanks, electrolytic cells, pipes, and scrubbers are used throughout battery production, including acid storage, electrolyte preparation, formation, washing, and exhaust treatment, helping control corrosion, leakage, and process contamination.

Chemical Processing

This project serves an industrial chemical processing system in Sweden. The production process requires multiple acidic raw materials to be stored separately, metered, transferred and diluted before being supplied continuously to downstream cleaning, surface treatment and other production equipment at a stable concentration. Residual liquids generated during equipment cleaning also need to be collected for reuse or transferred to a subsequent treatment system.

Mineral Processing

This project involved a mineral-processing thickening system developed for a large mining customer in Argentina. The thickener performs solid-liquid separation of mineral slurry. Under gravity, mineral particles settle toward the bottom of the equipment, while clarified liquid overflows from the upper section of the tank and enters the subsequent recycling or treatment system. Stable thickener operation helps improve process-water recovery and creates suitable conditions for downstream dewatering, conveying and tailings handling.

Municipal Infrastructure

This project serves a municipal wastewater collection and conveyance system in Canada. As wastewater volumes within the service area increased, the existing conveyance facilities gradually approached their design capacity during peak-flow conditions. A new pressurized pipeline was therefore required to transfer domestic sewage and wastewater from public facilities collected at a lift station to the downstream wastewater treatment system.

Water Treatment

This project involved an ammonia-containing wastewater treatment system supplied for a Japanese industrial environmental equipment company. The system receives ammonia-bearing process wastewater generated by chemical or electronics manufacturing operations. Through temporary storage, controlled transfer, ammonia stripping and subsequent off-gas treatment, ammonia is separated from the liquid phase and treated appropriately.

Air Treatment

This project serves an industrial off-gas treatment system for a copper-processing company in Kazakhstan. Material transfer, reagent preparation and hydrometallurgical operations in the production area generate exhaust gas containing fine particulates, moisture and corrosive components. The gas must therefore be enclosed, collected, treated by wet scrubbing and then discharged through a centralized exhaust system.

Energy Transition

Solvent extraction is a widely used separation and purification method in hydrometallurgy. The process takes advantage of differences in the distribution behavior of metal ions between an aqueous phase and an organic phase. This allows target metals to be selectively transferred from a multi-component solution and then recovered through stripping and subsequent refining steps.
