FRP Pipes for Acid Mist Purification & Absorption

FRP pipes for acid mist purification and absorption (FRP pipes) are high-performance composite pipes designed for corrosive gas treatment systems. They are made of resin matrix and glass fiber reinforced materials. Its excellent chemical corrosion resistance, light weight, high strength and long life make it the core conveying component of acid mist purification systems in chemical, metallurgical, electroplating and other industries. It can efficiently convey highly corrosive gases such as sulfuric acid, hydrochloric acid, nitric acid and mixed waste gas.

Product Performance

Super corrosion Resistance

Tested by NACE TM0175 standard, the annual corrosion rate is <0.1mm in 60% sulfuric acid and 37% hydrochloric acid environment.

Lightweight and Easy to Install

With a density of 1.8g/cm³, the weight of the same specification is only 1/4 of that of a steel pipe, reducing the cost of the bracket by more than 30%.

Maintenance-free Design

The inner wall is smooth (roughness 0.0084mm), with strong anti-scaling properties, and the flow rate loss is 40% lower than that of a steel pipe.

Environmental Protection and Energy Saving

The production energy consumption is only 1/3 of that of steel pipes, and 100% can be recycled.

Customized Service

Supports customization of pipe diameters from DN50 to DN3000mm, and can integrate multiple connection methods such as flanges, slip-ons, and sockets.

Production Process

Raw material Selection

Matrix resin: Acid-resistant epoxy resin, vinyl ester resin or furan resin is selected according to the characteristics of the medium.

Reinforcement material: Alkali-free glass fiber yarn and surface felt to ensure interlayer bonding and anti-permeability.

Molding Process

Wrapping molding: Computer controls the fiber winding angle and tension to achieve precise design of circumferential and axial mechanical properties.

Inner Lining Customization

2mm thick resin-rich layer + surface felt structure is used to form a high-density anti-corrosion barrier.

Curing Process

80℃ constant temperature curing + post-curing treatment to improve crosslinking density and dimensional stability.

Quality Inspection

Barcol hardness test (≥40), water pressure test (1.5 times design pressure), spark detection (5000V no leakage).
