01 Manufacturing Advantages
In the water treatment market, the difference between a tube settler that lasts 5 years and one that lasts 15 comes down to three manufacturing decisions most buyers never see: raw material grade, extrusion process control, and quality verification depth. Juntai builds all three on 55 closed-loop extrusion lines that hold channel width within ±0.2 mm - the precision that keeps every channel hydraulically identical so settling performance is repeatable module to module.

100%
Virgin Polymer
No recycled or regrind content. Every raw material batch tested for melt flow index and contamination before production release, with full supplier traceability. Result: uniform wall thickness and a 10–15 year service life even under continuous outdoor exposure.

8
International Certifications
FDA, SGS, NSF/ANSI 61, WRAS, KTW, ACS, DWI 31, CE - one of the most comprehensively certified tube settler ranges manufactured in China.
|
5-Stage
Quality Control
Incoming material → in-process dimensional checks (every 2 hr) → mechanical ASTM tensile/impact → UV accelerated aging (QUV) → final assembly go/no-go gauge verification.

03 Extrusion vs Thermoforming Manufacturing
Juntai uses precision extrusion - molten polymer pushed through a die - because it delivers tighter dimensional control, lower cost and full custom sizing. The table compares the two manufacturing methods across the factors that affect performance and price.

Factor
|
Extrusion (Juntai Method)
|
Thermoforming (Alternative)
|
|
Process
|
Molten polymer pushed through precision die
|
Flat sheet heated and moulded into corrugated shape
|
|
Tooling cost
|
Lower - die-based, fast changeover
|
Higher - mould fabrication required per design
|
|
Size flexibility
|
High - any length, custom profiles
|
Limited to mould dimensions
|
|
Beam strength
|
Moderate - requires closer support spacing
|
Higher - can span up to 8 ft unsupported
|
|
Assembly speed
|
Moderate - ~100 profiles per module
|
Faster - ~10 sheets per module

Dimensional precision
|
±0.2 mm - die-controlled, closed-loop
|
±0.5 mm - heat-induced variation
|
|
Cost per m²
|
Lower - continuous process, less labour
|
Higher - batch process, more energy

05 Applications & Industry Use Cases
|
Drinking Water - NSF/ANSI 61
φ25 mm food-grade PP modules (0.5 mm wall) reduce turbidity to <2 NTU ahead of filtration. NSF/ANSI 61 certification ensures material safety for drinking water contact.
Municipal Wastewater Clarifiers
φ35–50 mm PVC for plants handling 500–50,000 m³/d. Reduces downstream BOD load and retrofits into existing basins for 2–3× capacity without civil works.
Industrial Wastewater
φ50–80 mm heavy-duty PVC (1.0–1.2 mm wall) for mining, chemical and food & beverage effluent. Chemical-resistant against acidic/alkaline streams, variable TSS and shock loads.
OEM & Distributor Supply
8,000+ t/yr capacity supports bulk orders. ODM/OEM with custom packaging, private labelling and configuration-to-order. Free samples for qualified buyers.
