Product Introduction

FAQ

The FRP/GRP lye tanks we manufacture are corrosion-resistant storage and transportation equipment made primarily of fiber-reinforced plastic (FRP/GRP). Specifically designed for holding various alkaline solutions—such as sodium hydroxide solution, potassium hydroxide solution and sodium carbonate solution—they are widely used in industries including chemical engineering, metallurgy, pharmaceuticals, electroplating and wastewater treatment.

1. Superior Corrosion Resistance, Unaffected by Alkaline Erosion

FRP material features a unique molecular structure that delivers exceptional resistance to various alkaline solutions. Whether it is common strong alkalis such as sodium hydroxide solution and potassium hydroxide solution, or weak alkaline solutions of different concentrations, our FRP lye tanks ensure long-term stable storage. They effectively resist chemical erosion from lye, significantly extending the service life of the tanks, and reducing the frequency and cost of equipment replacement caused by corrosion.

2. Perfect Combination of High Strength and Lightweight Design

Crafted with advanced manufacturing processes, our FRP lye tanks achieve high strength while maintaining a lightweight profile. Compared with traditional metal storage tanks, they are easier to install and transport, lowering construction difficulty and transportation costs. Moreover, their high strength enables the tanks to withstand certain external pressure and impact, ensuring stable operation even in complex working environments and providing reliable protection for lye storage.

3. Excellent Temperature Adaptability

The storage temperature of lye needs to be controlled according to different process requirements. Our FRP lye tanks boast excellent temperature adaptability and can operate normally within a wide temperature range. Whether storing lye in high-temperature environments or using the tanks under low-temperature conditions, the tank body maintains superior performance without deformation, cracking, or other issues caused by temperature changes, thus ensuring the quality and storage safety of lye.

4. Outstanding Sealing Performance

Sealing performance is critical for lye storage. Our FRP lye tanks adopt professional sealing design and high-quality sealing materials, ensuring excellent airtightness at tank-pipeline joints and the tank body itself. This effectively prevents lye leakage and the entry of external impurities into the tank, which not only protects environmental safety but also guarantees the purity and quality of lye, meeting the stringent requirements of production processes.

5. Easy to Clean and Maintain

Regular cleaning and maintenance of storage tanks are essential to ensure the hygiene and safety of lye storage. The smooth surface of FRP lye tanks prevents the adhesion of dirt and impurities, making cleaning extremely convenient. Meanwhile, the material has good stain resistance and wear resistance. During long-term use, simple daily maintenance is sufficient to maintain the tank’s optimal performance, reducing maintenance costs and workload.

6. Customized Services to Meet Diverse Needs

We fully understand that different industries and enterprises have varying requirements for lye storage. Therefore, we provide comprehensive customized services. We tailor-make FRP lye tanks according to customers’ specific needs, such as capacity, shape and dimensions, and interface positions, ensuring that we meet all kinds of complex storage demands.
