Product Description

High-performance pressure-resistant FRP tank

The High-performance FRP (Fiber-Reinforced Plastic) pressure vessel is an advanced composite solution engineered for demanding industrial applications requiring exceptional corrosion resistance and mechanical strength. Manufactured through precision filament winding or contact molding processes, this vessel integrates high-strength glass fibers with thermosetting resin matrices to deliver outstanding pressure-bearing capacity, typically rated up to 10 MPa or higher depending on design specifications.

Redefining Pressure Vessel Standards with Composite Technology

The FRP (Fiber-Reinforced Plastic) pressure vessel represents a materials revolution in the field of pressurized storage tanks. Compared to traditional carbon steel or stainless steel vessels, it fundamentally addresses two core challenges that metal materials have long faced: corrosion failure and maintenance burden. By structurally combining high-strength glass fibers with corrosion-resistant thermosetting resins, FRP pressure vessels achieve excellent pressure-bearing capacity while inherently resisting attack from acids, alkalis, and salts — completely eliminating the risks of rust, pitting, and electrochemical corrosion.

Moreover, the lightweight nature of this composite material makes transportation, lifting, and on-site installation significantly more efficient, substantially reducing overall project costs. Whether applied in drinking water treatment, agricultural irrigation, industrial wastewater processing, or chemical storage and transport, FRP pressure vessels deliver reliable and economical solutions with a design life of up to 30 years and minimal maintenance requirements. Every unit undergoes rigorous hydrostatic testing and quality control in accordance with international standards such as ASME or ISO, ensuring absolute safety and long-term stability under critical operating conditions.

FAQ

Q: What is an FRP pressure vessel?
A: An FRP (Fiber-Reinforced Plastic) pressure vessel is a composite pressure equipment made from glass fiber-reinforced thermosetting resin, manufactured through filament winding or molding processes. It combines the high strength of glass fiber with the corrosion resistance of resin, and is widely used in water treatment, chemical industry, agricultural irrigation, food and beverage production, and other fields.

Q: What are the main advantages of FRP pressure vessels?
A: Superior corrosion resistance: Excellent tolerance to acids, alkalis, salts, and most organic solvents
Lightweight yet high-strength: Density is only 1/4–1/3 of steel, with tensile strength up to 150–300MPa
Long service life: Design life of 15–30 years under normal operating conditions
Low maintenance: Requires less frequent maintenance compared to steel tanks
Excellent insulation: Naturally non-conductive, no risk of electrochemical corrosion

Q: What is the operating temperature range of FRP pressure vessels?
A: The operating temperature range depends on the resin type selected:

Standard water treatment applications: 5°C – 50°C
Standard industrial applications (isophthalic resin): –20°C – 80°C
Vinyl ester resin: –40°C – 120°C
Special formulated resin: –50°C – 250°C

.

Q: What is the pressure rating of FRP pressure vessels?
A:Standard products are generally rated below 6.4MPa. Conventional pressure vessels for water treatment typically operate at 0.15MPa–0.6MPa. Higher pressure ratings can be achieved through special design and manufacturing. Specific pressure ratings should be customized based on operating conditions.

Q: How to choose the right resin type?
A: The resin type should be selected based on the corrosivity, temperature, and concentration of the stored medium:

Mild acid/alkali environments (pH 2–12, temp ≤80°C): Isophthalic unsaturated polyester resin
Highly corrosive conditions (hydrochloric acid, concentrated sulfuric acid, organic solvents, etc.): Vinyl ester resin (pH 0–14, temp ≤100°C)
High-temperature highly corrosive conditions: Epoxy resin (heat resistance up to 120°C)

Resin Type	Applicable pH Range	Temperature Range	Typical Applications
Isophthalic Unsaturated Polyester	pH 2–12	–20°C ~ 80°C	Mild acid/alkali environments, general water treatment
Orthophthalic Unsaturated Polyester	pH 4–10	–10°C ~ 60°C	Neutral media, cost-sensitive projects
Vinyl Ester Resin	pH 0–14	–40°C ~ 100°C	Highly corrosive conditions
Epoxy Resin	pH 1–14	–40°C ~ 120°C	High-temperature highly corrosive conditions
Special Formulated Resin	Customized	–50°C ~ 250°C	Extreme conditions, special media
