As two commonly used materials in modern pipeline engineering, hot-dip steel pipe and plastic-coated steel pipe have unique advantages and application fields.

Advantages and applications of hot-dip steel pipes

advantage

1. Superior anti-corrosion performance: hot-dip plastic steel pipe adopts hot-dip plastic process to form a uniform and dense plastic layer on the surface of the steel pipe, which effectively prevents the corrosion and rust of the steel pipe and prolongs the service life of the pipeline.

2. Good chemical resistance: The plastic layer has good chemical resistance, can resist the erosion of a variety of chemicals, and is suitable for the transportation of corrosive media in the fields of chemical industry and electric power.

3. Excellent mechanical properties: While maintaining the original mechanical properties of the steel pipe, the hot-dip plastic steel pipe improves the compressive, tensile and impact resistance of the pipe through the reinforcement of the plastic layer.

4. Convenient construction: The hot-dip plastic steel pipe adopts the socket connection method, which is convenient and quick to install, which reduces the workload in the installation process and improves the construction efficiency.

5. Environmental protection and energy saving: hot-dip plastic steel pipe is made of environmentally friendly materials, which is non-toxic and harmless, and there is no need to add any harmful substances in the production process, which is in line with the concept of green environmental protection. Its excellent thermal insulation performance also contributes to energy conservation and emission reduction.

apply

• Construction: used in building water supply and drainage, fire protection, air conditioning and other systems, its anti-corrosion, chemical resistance and good mechanical properties make it perform well in construction.

• Chemical industry: In the chemical industry, hot-dip plastic steel pipes can resist the erosion of a variety of chemical substances and are suitable for transporting corrosive media, such as acids, alkalis, salts, etc.

• Electric power field: It can be used in cable protection pipes, cable trays and other power facilities, and its good insulation performance and high temperature resistance make it widely used in the power field.

Advantages and applications of plastic-coated steel pipes

advantage

1. Good anti-corrosion performance: The plastic layer on the surface of the plastic-coated steel pipe can effectively isolate the contact between the steel pipe and the external environment, so as to play the role of anti-corrosion and corrosion resistance.

2. Multiple coating options: A variety of coating materials, such as EP (epoxy resin), PE (polyethylene), IPN8710 and epoxy coal pitch, have different performance characteristics, such as excellent corrosion resistance and wear resistance.

3. Convenient construction: Plastic-coated steel pipes do not need external anti-corrosion treatment during the construction process, which reduces the construction difficulty and construction period.

4. Beautiful appearance: Plastic-coated steel pipes can be selected in different colors according to needs to meet the design needs of different construction and engineering environments.

5. Cost-effective: The price of plastic-coated steel pipes is moderate, and compared with other corrosion-resistant pipes with high cost, it has a high cost performance.

apply

• Water supply system: It is widely used in urban water supply and drainage systems, agricultural irrigation, seawater transportation and other systems used to transport water sources.

• Chemical fluid transportation: It can be used in industrial chemical industry, petrochemical industry and other chemical industries to solve the transportation needs of various chemical fluids.

• Power communication: It can be used as a protective sleeve for cables and wires to protect cables and wires from erosion in special environments.

• Ventilation ducts: such as subways, highway tunnels and other areas that require ventilation ducts.

• Fire pipeline: professional fire-fighting plastic-coated steel pipe has the characteristics of high temperature resistance and good performance, which improves the service life of fire water supply, automatic sprinkler and other systems.

To sum up, hot-dip plastic steel pipe and plastic-coated steel pipe have their own advantages in anti-corrosion performance, mechanical properties, construction convenience, etc., and the specific selection should be comprehensively considered according to the actual use scenarios and needs.
