PP FRP Storage Tank

A PP FRP storage tank is a dual-laminate tank that uses an inner chemical-contact layer of polypropylene (PP) and an outer structural layer of fiberglass reinforced plastic (FRP), combining chemical compatibility with high mechanical strength. Compared with MS tanks, PP FRP tanks are completely corrosion-resistant to most acids, alkalis, and aggressive chemicals, eliminating frequent repainting, rubber lining, or premature replacement. Pure PP or HDPE tanks may deform or fail under higher temperatures, large volumes, or outdoor conditions, while the FRP outer shell gives PP FRP tanks superior rigidity and weather resistance. For Gujarat-based industries in Ankleshwar, Vapi, Dahej, and Hazira handling aggressive chemicals in hot climates, PP FRP tanks offer a much longer, safer service life with lower lifecycle cost than conventional options. This makes them ideal for chemical storage, effluent collection, process liquids, and intermediate bulk storage in demanding sites.​

Reconsky manufactures PP FRP storage tanks from 100 litres up to 300,000 litres (300 KL), covering everything from small dosing tanks to large plant-level storage solutions. Tanks are available in vertical and horizontal orientation, with cylindrical, square, and rectangular geometries, and can be supplied with flat, conical, or dished bottoms depending on drainage and process needs. Wall thickness typically ranges from 8 mm to 65 mm, engineered according to the design standards BS 4994, ASME RTP-1, and ASME Section X to safely manage pressure, vacuum, and wind loads. Customers can specify accessories such as level indicators, manholes, ladders, railings, nozzles, and inspection ports to match their plant layout and safety requirements. Colour options like white, black, green, yellow, or custom shades help with chemical identification, heat absorption control, and site aesthetics.​

The PP inner layer is compatible with a wide variety of inorganic acids (such as HCl, H₂SO₄, HNO₃ in defined concentrations), alkalis (NaOH, KOH), salts, and many organic chemicals, making PP FRP tanks suitable for most chemical, pharma, and ETP applications. The outer FRP shell, built with resins such as Isophthalic, Bisphenol, Vinylester, or Epoxy, provides additional resistance to permeation and mechanical damage in harsh environments. Standard designs support temperatures up to around 130 °C depending on resin system and wall construction, enabling safe storage of hot process liquids and elevated-temperature effluents. Tanks are also UV-protected for outdoor installation, ensuring that intense sun and monsoon conditions, common in Gujarat, do not degrade performance or aesthetics. For highly specialised media like solvents, oxidising agents, or mixed streams, Reconsky’s technical team reviews the chemical resistance chart and proposes the most suitable dual-laminate combination.​

PP FRP tanks are designed as essentially maintenance-free vessels because the corrosion-resistant PP inner layer and FRP structural shell do not require periodic painting, rubber lining replacement, or cathodic protection that MS tanks often need. The glossy internal finish reduces residue build-up, improves flow, and simplifies cleaning, which lowers downtime and CIP (clean-in-place) effort. Precision fabrication and leak-proof welding ensure zero water assimilation and minimise the risk of leakage-related product loss, environmental incidents, and unplanned outages. Because of their long service life and low repair frequency, PP FRP tanks deliver a much lower cost per year of operation compared to steel or basic plastic tanks, especially in high-corrosion segments. For owners and maintenance teams in Gujarat’s chemical clusters, this means more predictable OPEX, easier compliance with insurance and safety audits, and better long-term ROI on capex.​

Reconsky designs PP FRP tanks according to recognised international standards like BS 4994 and ASME Section X, providing detailed drawings, design calculations, and material specifications for client and consultant review. For new projects or replacement of MS tanks, the team can assist with site evaluation, nozzle orientation planning, load considerations on RCC foundations, and tie-ins with existing piping. Tanks are factory-tested for leak-proofness and mechanical integrity, and can be supplied with inspection and test certificates that support statutory compliance, internal audits, and third-party approvals. During and after installation, Reconsky offers guidance on safe lifting, positioning, anchoring, hydrotesting, and commissioning to ensure trouble-free start-up. Long-term, customers benefit from local technical support across Gujarat and other industrial regions, including advice on expansion, relocation, or integration with scrubbers, reactors, and process systems.
