Air suction hose — smooth-wall thermoplastic
TECTUL · Dispatch across Colombia · Exports to Central & South America
Hose made of soft smooth-inner-wall thermoplastic tube, for ventilation systems, industrial vacuum cleaners, dust collection and air-suction applications. Covers 1″ to 6″, in 30 to 60 meter rolls depending on diameter, with working pressure from 30 to 60 psi decreasing with diameter and burst pressure from 90 to 180 psi. Steel wire reinforcement options available for heavier suction applications. Smooth inner wall for optimal airflow and reduced friction.
IMPORTANT: reference data — may differ from the physical product; verify with an advisor before buying.

IMPORTANT
This technical data sheet is a reference guide to the properties of this product type; it is not a quality certificate for the product you are buying. The measurements, dimensions and physical or geometric characteristics of the product supplied may vary by manufacturer, heat and lot, and may even fall outside the cited standards. If any of these figures is critical to your design or build, verify it with one of our advisors against the physical product or the lot's mill certificate, so you can be fully certain of what you are buying. · Original data sheet: tectul.com/en/conduccion-de-fluidos/mangueras/ficha-tecnica-manguera-para-succion-de-aire.html

2. Why wall thickness grows with diameter and when to request steel reinforcement
Wall thickness rises from 3.5 mm at 1″ to 7.0 mm at 6″: at a larger diameter, an unreinforced thermoplastic wall needs more thickness to avoid collapsing under suction vacuum, which also explains why allowable W/P drops from 60 psi at small diameters to 30 psi at 6″. The manufacturer offers a steel-wire-reinforced option for heavier suction — dense dust, more aggressive particles, or deeper vacuum — but does not publish a separate pressure table for it; if the application demands heavy suction, confirm with the supplier whether you need that reinforced variant instead of the unreinforced version in this table.
3. FREQUENTLY ASKED QUESTIONS
Do I need the steel-reinforced version?
Only for heavy suction applications (dense dust, abrasive particles, deeper vacuum); the manufacturer offers that option but does not publish a separate pressure table for it, so confirm with the supplier.
What is the temperature range?
The manufacturer declares it "can operate within a standard temperature range" without publishing numeric values; if the service includes hot air, confirm the exact limit with the supplier.
Why does pressure drop with diameter?
Because wall thickness does not grow proportionally with diameter; see this sheet's technical note.
4. Application notes
Feasibility
Confirm the exact temperature limit with the supplier if the air to be suctioned is hot; the manufacturer does not publish a numeric value.
Installation
Do not exceed the table's W/P by diameter; for heavy suction consider the steel-reinforced variant.
Design
Select diameter by required airflow, always verifying the corresponding allowable W/P.
5. Technical notice and limitation of liability
The pressures, dimensions, weights and other characteristics in this sheet are theoretical calculation values obtained from nominal properties published in the standards cited (ASME B36.10-2022, ASME B31.3-2024, ASTM A106/A106M-19a, ASTM A53/A53M-24, API Spec 5L 46th ed.). They guide selection; they are not a certificate of conformity for any given lot.
The actual behavior of each lot varies with manufacturing — wall tolerance (up to −12.5%), out-of-roundness, residual stresses — and with the raw material — chemical composition within the ranges the standard allows, heat-to-heat differences. To certify a lot, the tests defined by its product standard are required: tensile test, flattening test and hydrostatic test, documented in the manufacturer's mill test certificate (MTC), which TECTUL supplies upon request; testing of the lot in an independent laboratory can also be arranged.
These values must not be used as the sole criterion in critical or safety applications, or wherever failure of the line may compromise people, property or the environment: in such cases the design belongs to the project's responsible engineer under the applicable code (ASME B31.3, B31.1 or the one governing the installation), with the design temperature, corrosion allowance and load cases of the actual service. Before deciding with these data, consult our technical team.
