As customization of duct pipe fittings is available at Foshan NuoWei Ventilation Co., Ltd., customers can negotiate with our after-sales team for more details. Specifications and parameters should be provided for us to carry out sample design.
In this project, we provided the customer with a highly efficient insulation air conditioning insulation duct system, which is closely integrated with the grain chiller to optimize the temperature and humidity control of the grain storage environment.
Through in-depth communication with customers, we designed a special thermal insulation duct to meet the needs of grain chillers, using high-quality thermal insulation materials to ensure that the system maintains stable performance in low temperature and high humidity environment. Our factories are responsible for production and ensure that products are delivered to customers quickly and safely. Finally, the successful application of the thermal insulation duct system has significantly improved the preservation effect of grain and reduced energy consumption, and our air conditioning insulation duct has also been highly recognized by customers.
Introduction
In the design of industrial ventilation system, PVC flexible duct has become the mainstream choice because of its corrosion resistance and easy installation. Facing the market demand division between 0.38mm standard model and 0.6mm thickened model, this paper objectively analyzes the adaptability scenario of the two specifications through laboratory data and engineering examples.
I. Comparison of core parameters (Source: ASTM D1204 test standard)
| Norm | 0.38mm Standard | 0.6mm Thickened |
| Burst pressure (25℃) | 0.12MPa | 0.25MPa |
| Bending fatigue life (times) | 15,000 | 35,000+ |
| Unit weight (g/m³) | 480 | 780 |
| Puncture resistance (N) | 320 | 650 |
II. Guidelines for Matching Typical Application Scenarios
▶ Preferred case for 0.38mm standard model
1.Short-term temporary ventilation system
Construction site dust removal, temporary exhaust ventilation for exhibitions and other projects <6 months, measured material cost savings of 37%.
2.Low pressure circulation system
Suitable for air exchange in workshops with fan pressure <800Pa, with steel ring support to meet ISO 14644 cleanliness requirements.
3.Lightly corrosive environment
Stable performance in conventional acid and alkali environments of pH 5-9, suitable for food processing and electronic assembly workshops.
▶ Recommended conditions for 0.6mm thickened models
1.High-risk operating environments
Scenarios with sharp object impacts such as metal grinding, slag transportation, etc., with a 210% increase in abrasion resistance (see OSHA 1926.55 standard)
2.High temperature and high pressure system
High-temperature exhaust emissions below 80°C, with fiberglass reinforcement to withstand 1.5 times the design pressure
3.Permanent installation
Pharmaceutical factory GMP workshop, underground parking lot and other places that require more than 10 years of service life
III. Full life-cycle cost model
| cost item | 0.38mm Standard | 0.6mm Thickened |
| Initial procurement costs | ¥18-22/extended meter | ¥32-38/extended meter |
| Average annual maintenance costs | 12% | 6% |
| Total holding costs over 5 years | reference value | 18% lower |
Note: TCO analysis based on a 5-year life cycle of 200 meters of pipe, including replacement losses and downtime costs.
IV. Engineering decision tree tool
1.Is the system design pressure >1200 Pa? → Yes → Select 0.6mm
2.Is it exposed to high temperature oil mist/metal debris? → Yes → Select 0.6mm
3.Is the budget limited to ¥25/m? → Yes → Select 0.38mm
4.Do you need to change the pipe frequently? → Yes → Choose 0.38mm
V. Industry Application Trends Report (2024)
●Automotive Manufacturing: 0.6mm models increased to 67% of welding shop use
●Data center: 0.38mm models due to the lightweight advantage of cold aisle applications increased by 41
●Environmental protection industry: the two specifications in the VOCs management shows 1:1 procurement ratio
concluding remarks
Thickness selection is essentially a systems engineering optimization problem. It is recommended that this be done prior to procurement:
● Media composition test (with particle hardness analysis)
● Pressure pulsation test
● Full cycle cost simulation
Energy efficiency of ventilation systems can be increased by 15%-40% through scientific selection.
