Detailed Manufacturing Process of FRP Rectangular Tanks

The fabrication of high-quality Fiber Reinforced Polymer (FRP) Taisnstūra tvertnes is a sophisticated process demanding precision engineering and adherence to stringent quality control protocols. Our manufacturing methodology leverages advanced techniques to ensure exceptional durability, chemical resistance, and structural integrity. The primary steps are outlined below:

1. Material Selection & Preparation

We meticulously select premium raw materials, primarily high-grade thermosetting resins (e.g., Isophthalic Polyester, Vinyl Ester for enhanced chemical resistance) and various fiberglass reinforcements (e.g., chopped strand mat, woven roving, continuous roving). Resins are chosen based on the stored media's chemical compatibility and operating temperature. Reinforcements provide the necessary tensile and flexural strength.

2. Panel Fabrication (Hand Lay-up & Pultrusion)

For Taisnstūra tvertnes, individual panels are typically manufactured. This involves hand lay-up or specialized pultrusion for consistent thickness and strength. Layers of fiberglass reinforcement are saturated with resin and carefully rolled to remove air voids, creating a monolithic structure. Corrosion barriers (C-veil or synthetic veil layers) are incorporated into the inner surface for superior chemical resistance.

3. Curing Process

After lamination, panels undergo a controlled curing process. This involves maintaining specific temperature and humidity conditions to facilitate the polymerization of the resin, resulting in a hardened, structurally stable composite. Post-curing may be applied to optimize resin properties and achieve maximum chemical resistance.

4. Assembly & Bonding

The cured panels are precisely cut (often using CNC machining for accuracy) and then assembled using specialized FRP bonding techniques. This involves laminating joints with additional layers of fiberglass and resin, creating seamless, leak-proof connections. Internal baffles, external stiffeners, and support structures are integrated at this stage.

5. Finishing & Quality Assurance

Upon assembly, the tank undergoes thorough internal and external finishing, including surface treatment and application of UV-resistant coatings if required. A comprehensive quality assurance program follows, including visual inspection, barcol hardness testing, dimensional checks, and hydrostatic testing to verify leak tightness and structural integrity.

Our FRP Taisnstūra tvertnes are designed to comply with international testing standards such as ASTM D3299 for filament-wound FRP tanks and ASME RTP-1 for reinforced thermoset plastic corrosion resistant equipment, ensuring a design service life typically exceeding 20-30 years with proper maintenance. These tanks are ideal for target industries including petrochemical, chemical processing, metallurgy, power generation, and municipal water supply & drainage, offering advantages such as superior corrosion resistance, energy saving due to reduced pumping requirements (lighter weight), and minimal maintenance compared to metallic alternatives.
