FRP spray pipe: an efficient and environmentally friendly industrial fluid delivery solution

As a high-performance composite material pipe, FRP spray pipe is made of resin (such as food-grade epoxy resin, vinyl ester resin) and glass fiber as the base material through a fiber winding process. It has the core advantages of light weight, high strength, corrosion resistance, wear resistance, and long life. It has been widely used in fluid delivery systems in chemical, electric power, environmental protection, metallurgy and other industries. 

Characteristics and application value

Super corrosion resistance: acid/alkali/salt/organic solvent/seawater/sewage resistant, chemical stability is better than stainless steel (anti-chloride pitting) and PP (heat resistance and anti-aging), special lining coating is suitable for harsh scenarios such as power plant desulfurization and chemical wastewater.

Lightweight, high strength & heat and pressure resistance: density is only 1/4 of steel, single length ≥9 meters (installation efficiency ↑30%), pressure resistance ≥300MPa, temperatureresistance -70℃~220℃ (instantaneous 250℃), pressure 0.1-4.0MPa, meeting the needs of multiple working conditions.

Long life & low maintenance: design life ≥50 years, no anti-corrosion treatment required, maintenance cost ↓50% compared with traditional pipelines, suitable for long-term operation systems (such as synchronous life of power plant desulfurization tower).

Energy saving & impact resistance: The inner wall is smooth (roughness coefficient ≤ 0.0084), energy consumption is ↓15%-20%; impact resistant (20kg sandbag impacts 1 meter 15 times without deformation), earthquake resistant, and adaptable to complex geology.

customized to meet multiple needs

Composite structure design

The multi-layer composite process of "lining layer + structural layer + outer protective layer" is adopted:

1. Lining layer: high resin content corrosion-resistant layer to ensure safe contact with the medium;

2. Structural layer: glass fiber winding reinforcement layer to provide mechanical support;

3. Outer protective layer: anti-aging layer or wear-resistant layer (such as adding fillers such as silicon carbide and alumina) to extend the service life in outdoor or wear scenarios.

Flexible customization scheme

1. Wide range of specifications: pipe diameter DN10-DN4000mm, pressure level 0.1-4.0MPa, temperature resistance range -70℃ to 220℃, wall thickness, winding angle and resin system can be adjusted according to working conditions;

2. Various connection methods: flange connection, socket connection, winding and wrapping connection, etc., easy installation and strong sealing;

3. Special scene adaptation: for example, food-grade resin pipes can be used for drinking water transportation, and conductive coating pipes are suitable for anti-static environment.

Intelligent manufacturing and quality assurance

The microcomputer-controlled long fiber reciprocating winding process is adopted to ensure uniform fiber distribution, high interlayer bonding strength, and avoid circumferential cracks. The production process has passed the ISO9001 quality management system certification and is equipped with a CNAS certification testing center to conduct full-process testing of raw materials, mechanical properties, corrosion resistance, etc.

Application

Power industry: core components of desulfurization and denitrification

In the wet desulfurization system of power plants, FRP spray pipes are used as slurry transportation and spraying devices inside the absorption tower. They can withstand the scouring and corrosion of high-concentration gypsum slurry, with a service life of more than 30 years, and there is no need to worry about the rubber layer falling off and clogging like steel-lined rubber pipes. For example, after a power plant adopted FRP spray pipes, the annual maintenance cost was reduced by 32.8%, and the system stability was significantly improved.

Chemical and Environmental Protection: Expert in Corrosive Media Transportation

1. Chemical Production: Transport strong acids, strong alkalis, organic solvents and other media, replacing stainless steel or PP pipes, reducing costs by 20%-30%;

2. Sewage Treatment: Resistant to sewage corrosion, smooth inner wall and not easy to scale, suitable for municipal sewage pipe network, industrial wastewater treatment pool and seawater desalination projects;

Waste gas treatment: As the circulating water pipeline inside the spray tower, it can efficiently treat sulfur-containing and chlorine-containing waste gas, and with activated carbon adsorption or centrifugal fan, it can achieve a purification efficiency of more than 98%.

Metallurgy and Energy: Optimum for High-temperature and Wear-resistant Scenarios

In the dust removal system of steel plants, sintering furnace flue gas treatment and mine tailings transportation, FRP spray pipes can withstand high-temperature dust erosion and wear, and are light in weight and easy to install, greatly reducing the difficulty and cost of construction.

Municipal and Construction: A New Choice for Safety and Environmental Protection

Food-grade resin pipes are used for drinking water transportation to ensure long-term water quality hygiene; their corrosion resistance makes them an ideal material for urban water supply and drainage, fire sprinklers and landscape waterscape projects.

Cost-effectiveness and service advantages

Outstanding economic efficiency

Initial investment: Under the same specifications, the price of FRP sprinkler pipe is 75%-90% of steel lined rubber pipe and 60%-70% of stainless steel pipe, and no additional anti-corrosion treatment is required;

Life cycle cost: The maintenance-free and long-life characteristics reduce its comprehensive cost by more than 40% compared with traditional pipes, which is especially suitable for long-term operation projects.
