Cili është tubi më i mirë për t'u përdorur për kullimin nëntokësor?

Në sistemin e kullimit nëntokësor të inxhinierisë komunale, projektet industriale dhe zonat e banuara, zgjedhja e tubave është shumë e rëndësishme. Përballë tubit kryesor PPR, PVC pipe and HDPE pipe in the market, engineers and decision makers need to comprehensively consider multiple factors such as corrosion resistance, high pressure resistance, installation process and economic benefits. Although PPR pipe and PVC pipe can also meet the requirements under certain conditions, Tub i valëzuar me dy mure HDPE with high pressure performance and excellent corrosion resistance, has become an increasingly ideal choice in underground drainage systems.

Pjesë 1, PPR Pipe: The Balance Choice of High Ttemperatura Resistance and Corrosion Rekzistencës

PPR Pipe Ckarakteristikat

tub PPR (tub polipropileni kopolimer i rastësishëm) is known for its high temperature resistance (long-term use temperature 70℃) and chemical corrosion resistance, and its molecular structure is stable, especially suitable for transporting industrial wastewater containing acid and alkali components. Its inner wall smoothness reaches Ra≤0.1μm, which can effectively reduce scale deposition.

Tub PPR Aavantazhet

Rezistenca ndaj korrozionit: Resists pH 2-12 liquids to avoid the risk of metal pipe rust

Lidhja e shkrirjes së nxehtë: the strength of the welding reaches 90% of the body material, preventing potential leakage

Jeta e shërbimit: design life of 50 vjet, low maintenance cost

Tub PPR Aplikimi Suggestions

Chemical park wastewater discharge system

Ground source heat pump circulating water pipe network

High temperature steam condensate recovery pipeline

PPR Pipe Aanaliza

The impact strength is only 20kJ/m² (23 ° C), and the heavy duty vehicle rolling area should be avoided Linear expansion coefficient 0.15mm/(m·K), need to set expansion joint compensation

Pjesë 2, PVC Pipe For Drainage Sistemi: Cost-effective Choice

Aanaliza Of PVC U Pipe Performanca Parameter

PVC-U Pipe (hard polyvinyl chloride pipe) with 0.6-1.6MPa ring stiffness and a cost advantage of 3-8$ per meter, occupy 60% share of the global underground drainage system. Its Vica softening point is ≥79℃, which can meet the requirements of conventional drainage temperature.

PVC U Pipe Advantage

Cost-effective: Cost of PVC U pipe raw material is 30%-40% lower than HDPE

Convenient construction: No professional equipment is required for socket connection, dhe efikasiteti i instalimit rritet me 50%

Biological Erosion Rekzistencës: Not decomposed by microorganisms, suitable for sewage environment

PVC U Pipe Aaplikimi

Residential rainwater collection network

Municipal road side ditch drainage system

Low corrosive industrial wastewater discharge

PVC U Pipe Using Tips

Low temperature impact resistance is poor (embrittlement temperature -5℃), the northern region needs to add a toughening agent

Long-term use temperature does not exceed 45 ° C, avoid conveying high temperature media

Pjesë 3, HDPE Pipe: A Technical Model of High Pburim Rekzistencës And Flexibility

The ring stiffness of HDPE double-wall corrugated pipe can reach SN8 level (8kN/m²), and the elastic bending rate of 1:100 has become the first choice for earthquake zones and settling areas. Its elongation at break exceeds 350% and can withstand 3% of foundation deformation.

Tub i valëzuar me dy mure HDPE characters

Rezistencë ndaj presionit të lartë: HDPE pipe has a very high pressure resistance, and can effectively resist external loads under underground stress conditions to ensure long-term stable operation. This is also one of the important reasons for choosing high pressure drainage pipes.

Rezistenca ndaj korrozionit: HDPE material itself has strong chemical resistance and corrosion resistance, whether it is industrial wastewater or urban sewage, HDPE pipe can maintain stable performance and become the ideal choice for corrosion resistant sewage pipes.

Light weight and easy to installation: HDPE pipe is light in weight, more convenient for transportation and installation, and its flexible design makes it easier to adapt to terrain changes in the design specification of underground pipe network, reducing the risk caused by foundation settlement.

Jetë e gjatë shërbimi: Because HDPE pipe is not susceptible to corrosion and aging, its service life can usually reach more than 50 vjet, in line with international drainage pipe standards, to ensure the maximum return on investment.

Tub i valëzuar me dy mure HDPE advantage

Zero leakage connection: electric fusion connection to achieve molecular level fusion

Wear resistance: the wear coefficient is 4 times that of the steel pipe, suitable for the medium containing gravel

Eco-friendly: 100% të riciklueshme, in line with green building standards

Tub i valëzuar me dy mure HDPE applications

Highway integrated pipe corridor drainage

Landfill leachate collection system

Coastal saline drainage works

Tub i valëzuar me dy mure HDPE kosto

The use of winding structural wall pipe (HDPE-SSP) can reduce the material consumption by 15%

The life cycle cost is 40% lower than that of concrete pipe

Part 4,Comparison of HDPE Pipe,Tub PVC & Tub PPR

Part 5,How To Choose The Correct Pipes

1. Geological conditions are preferred:

 Earthquake zone/soft ground → Select HDPE pipe

 Stable rock formation → Consider PVC pipe to reduce costs

2. Medium characteristics orientation:

 Oil/high temperature wastewater → PPR pipe

 Containing solid particles → HDPE double-wall bellows

3. Budget constraint considerations:

 Short-term project → PVC pipe

 Centennial Project → HDPE pipe
