Какую трубу лучше всего использовать для подземного дренажа?
В подземной дренажной системе городского строительства, промышленные проекты и жилые районы, выбор труб очень важен. Перед лицом основных труб PPR, PVC pipe and HDPE pipe in the market, engineers and decision makers need to comprehensively consider multiple factors such as corrosion resistance, устойчивость к высокому давлению, installation process and economic benefits. Although PPR pipe and PVC pipe can also meet the requirements under certain conditions, Двухстенная гофрированная труба HDPE with high pressure performance and excellent corrosion resistance, has become an increasingly ideal choice in underground drainage systems.

Часть 1, ППР Пипе: The Balance Choice of Hай Ттемпература Рesistance and Сorrosion Рсуществование
PPR Pipe Cхарактеристики
ППР труба (полипропиленовая труба из рандом-сополимера) 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.
ППР трубы Апреимущества
Коррозионная стойкость: Resists pH 2-12 liquids to avoid the risk of metal pipe rust
Соединение горячего расплава: the strength of the welding reaches 90% of the body material, preventing potential leakage
Срок службы: design life of 50 годы, низкая стоимость обслуживания
ППР трубы Приложение Сuggestions
Chemical park wastewater discharge system
Ground source heat pump circulating water pipe network
High temperature steam condensate recovery pipeline
PPR Pipe Aанализ
The impact strength is only 20kJ/m² (23 °С), and the heavy duty vehicle rolling area should be avoided Linear expansion coefficient 0.15mm/(м·К), need to set expansion joint compensation

Часть 2, ПВХ Пипе Для Дrainage Система: Cost-effective Choice
Аанализ Of ПВХ U Pипе Performance Ппараметр
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
Удобная конструкция: No professional equipment is required for socket connection, и эффективность установки увеличивается на 50%
Biological Эrosion Рсуществование: Not decomposed by microorganisms, suitable for sewage environment
PVC U Pipe Aзаявление
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 °С, avoid conveying high temperature media
Часть 3, ПНД Пипе: А Ттехнический Мodel of ЧАСай Пресурс Рсуществование Аnd Фlexibility
The ring stiffness of HDPE double-wall corrugated pipe can reach SN8 level (8кН/м²), 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.
Двухстенная гофрированная труба HDPE 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.
Коррозионная стойкость: 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 и прост в установкеation: HDPE pipe is light in weight, более удобен для транспортировки и установки, 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.
Длительный срок службы: Because HDPE pipe is not susceptible to corrosion and aging, its service life can usually reach more than 50 годы, in line with international drainage pipe standards, to ensure the maximum return on investment.
Двухстенная гофрированная труба HDPE advantage
Zero leakage connection: electric fusion connection to achieve molecular level fusion
Износостойкость: the wear coefficient is 4 times that of the steel pipe, suitable for the medium containing gravel
Eco-friendly: 100% пригодный для вторичной переработки, in line with green building standards
Двухстенная гофрированная труба HDPE applicationс
Highway integrated pipe corridor drainage
Landfill leachate collection system
Coastal saline drainage works
Двухстенная гофрированная труба HDPE расходы
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 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
