Tub de PE Vs Tub de PVC en el reg agrícola: Anàlisi Comparativa

Amb la creixent demanda d'estalvi d'aigua eficient en l'agricultura moderna, el disseny científic del sistema de reg i la selecció de materials de canonades s'han convertit en la clau. As the core components of agricultural irrigation, PE (polietilè) canonades and PVC (clorur de polivinil) pipes are widely used because of their performance advantages. This paper will deeply analyze the specific application scenarios, specifications and selection suggestions of the two materials in agricultural irrigation, to help users optimize the design of irrigation system.

PE Pipe in Agricultural Irrigation Aaplicaciós & Paràmetres

Due to its flexibility, corrosion resistance and low temperature resistance, Tubs de PE are widely used in the following scenarios:

Sistemes de reg per degoteig: PE pipes can achieve precise irrigation through microholes or drippers, especially suitable for cash crops such as fruit trees and vegetables.

Mobile sprinkler irrigation: The lightweight PE pipe is easy to disassemble and assemble, suitable for seasonal irrigation or temporary water supply needs.

Buried underground irrigation: PE pipe is resistant to soil chemical corrosion, suitable for long-term buried use, reduce the risk of pipeline aging.

Hilly and complex terrain: its flexibility can adapt to terrain fluctuations, reduce the use of connectors, reduce the probability of water leakage.

Tub de PE en Reg Agrícola Sespecificacions &Models

PE pipe specifications commonly used in agricultural irrigation are divided according to pressure grade and pipe diameter:

Classe de pressió: PN6 (0.6MPa), PN8 (0.8MPa), PN10 (1.0MPa), suitable for scenarios with different water pressure requirements.

Pipe diameter range: DN16mm to DN315mm, of which DN50mm-DN160mm is the mainstream model for agricultural irrigation.

Standard reference: d'acord amb GB/T 13663.2-2018 “Polietilè (PE) pipe system for water supply” estàndard, to ensure pressure resistance and environmental protection performance.

Advantages of PE Pipe in Agricultural Irrigation

Resistència a baixa temperatura (-20℃ ~ 40 ℃), suitable for cold areas.

Flexible and easy to lay, low construction cost.

Strong impact resistance and service life of up to 50 anys.

PVC Pipe in Aagrícola jorrigation Application & Paràmetres

Tub de PVC is known for its high strength and low cost, and is mainly used in:

Trunk water pipeline: The rigid structure is suitable for long distance and large flow water transmission, such as the laying of the main pipe from the reservoir to the field.

Fixed sprinkler irrigation system: through flange or adhesive connection, high stability, suitable for large-scale farmland.

Open channel replacement project: PVC pipe can replace the traditional earth channel, reduce leakage, improve the efficiency of water transmission.

Irrigation inside the greenhouse: superfície llisa, no és fàcil d'escalar, suitable for humidity control needs in the greenhouse.

PVC Pipe in Aagrícola joregadiu Especificacions & Models

PVC pipe for agricultural irrigation should meet the following parameter standards:

Nominal pressure: 0.6MPa, 0.8MPa, 1.0MPa, corresponding to different wall thicknesses (such as Φ110mm pipe wall thickness of 3.2mm-4.2mm).

Pipe diameter range: DN20mm to DN400mm, of which DN90mm-DN200mm is the common model.

Execution standard: in accordance with GB/T 13664-2006 “Hard polyvinyl chloride (PVC-U) pipe for Low pressure irrigation”, to ensure pressure resistance and durability.

Aavantatges de PVC Pipe in Aagrícola joregadiu

Alta rigidesa, suitable for ground fixed laying.

The cost is lower than PE tube, and the economy is outstanding.

Good high temperature resistance (working temperature 0℃~45℃).

PE Pipes Vs Tub de PVCs Comparative Analysis

Indicadors	Tub de PE	PVC piping
Flexibilitat	Tall, transportable in coils	Baixa, need to be connected in sections
Resistència a baixa temperatura	No cracking at -20℃	It is easy to embrittlement below 0℃
Resistance to chemical corrosion	Excel·lent (especially acid and alkali resistance)	Bé (not resistant to strong oxidants)
Mètode de connexió	Soldadura per fusió en calent, good sealing	Adhesive or flanged, necessiten un manteniment regular
Vida útil	50 + anys	20-30 anys
Cost	Més alt	Abaix

Selection suggestions:

– Terrain complex or low temperature environment: PE pipe is preferred.

– Long distance fixed water delivery: PVC piping is recommended to control costs.

– Drip irrigation/sprinkler irrigation system: Depending on budget and maintenance conditions, PE pipe is suitable for long-term use, PVC pipe is suitable for short-term projects.

PE pipe and PVC pipe have their own advantages in agricultural irrigation, and users need to scientifically select them according to the specific terrain, budget and maintenance conditions. As a professional pipe manufacturer, we provide high-quality PE/PVC irrigation pipes that meet national standards, support customized specifications and services, and help the global agriculture to achieve efficient water conservation goals.
