What Is The Best Pipe To Use For Underground Drainage?

In the underground drainage system of municipal engineering, industrial projects and residential areas, the choice of pipes is very important. In the face of the mainstream PPR pipe, PVC pipe and HDPE pipe in the market, engineers and decision makers need to comprehensively consider multiple factors such as corrosion resistance, югары басымга каршы тору, installation process and economic benefits. Although PPR pipe and PVC pipe can also meet the requirements under certain conditions, HDPE ике диварлы грипп торба with high pressure performance and excellent corrosion resistance, has become an increasingly ideal choice in underground drainage systems.

Partлеш 1, PPR Б.ipe: The Balance Choice of High Т.император Р.esistance and C.orrosion Р.барлыгы

PPR Pipe Characteristics

PPR торба (очраклы кополимер полипропилен торба) 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.

PPR торба А.өстенлекләр

Коррозиягә каршы тору: Resists pH 2-12 liquids to avoid the risk of metal pipe rust

Кайнар эретү тоташуы: the strength of the welding reaches 90% of the body material, preventing potential leakage

Хезмәт вакыты: design life of 50 еллар, low maintenance cost

PPR торба Заявка С.uggestions

Chemical park wastewater discharge system

Ground source heat pump circulating water pipe network

High temperature steam condensate recovery pipeline

PPR Pipe Analysis

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

Partлеш 2, ПВХ Б.ipe For D.rainage Система: Cost-effective Choice

А.nalysis Of ПВХ U Pipe Performance Б.араметр

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

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

Convenient construction: No professional equipment is required for socket connection, һәм урнаштыру эффективлыгы арта 50%

Biological E.rosion Р.барлыгы: Not decomposed by microorganisms, suitable for sewage environment

PVC U Pipe Aүтенеч

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

Partлеш 3, HDPE Б.ipe: А. Т.эхник М.odel of Н.igh Б.ресурс Р.барлыгы А.nd F.лексика

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.

HDPE ике диварлы грипп торба characters

High pressure resistance: 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.

Коррозиягә каршы тору: 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 һәм урнаштыру җиңелation: 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.

Озын хезмәт гомере: Because HDPE pipe is not susceptible to corrosion and aging, its service life can usually reach more than 50 еллар, in line with international drainage pipe standards, to ensure the maximum return on investment.

HDPE ике диварлы грипп торба advantage

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

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

Eco-friendly: 100% эшкәртелә торган, in line with green building standards

HDPE ике диварлы грипп торба кушымтас

Highway integrated pipe corridor drainage

Landfill leachate collection system

Coastal saline drainage works

HDPE ике диварлы грипп торба cost

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,ПВХ торба & PPR торба

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
