HardLine-MAX™ (Round and Oval)
Semi-rigid polymer tubing for horizontal mine and tunnel ventilation.
FEATURES:
-
HardLine tubing can be formed to round or oval.
-
Oval is designed to maximize drift/tunnel headroom by 25%.
-
Resilient and durable polymer material (RigiFLEX-FR) is purpose-built for mine and tunnel ventilation.
-
Tubing offers industry-leading high-efficiency airflow and low-leakage coupling.
-
Available for positive and negative pressure applications.
-
Hi-visibility safety green color.
-
Quick-to-install coupling system.
-
Fire Resistant for mine safety and to meet local codes.
-
For shipping and storage HardLine Ducting is compressed down to help reduce cost.
SPECIFICATIONS:
Diameter Range: 14” – 72” (356mm – 1830mm)
Standard Length: 8’ and 10’ (2.45m, 3.05m). Longer lengths available.
MATERIAL:
-
RigiFLEX-FR Polymer Grades:
-
SD (Standard Duty) for light-weight and positive pressure applications.
-
MD (Medium Duty) for positive and moderate negative pressure applications
-
XD (Extreme Duty) for accessories, negative pressure and high-impact applications.
-
-
RigiFLEX-FR offers a consistent and smooth surface to maximize airflow efficiency.
-
Polymer does not fracture, de-laminate or lose bond.
-
Safe to handle as there are no fibers that fracture, cut or contaminate the air.
HardLine-MAX™ COAL
Semi-rigid polymer tubing for horizontal coal mine ventilation.
FEATURES:
-
Tubing offers industry-leading high-efficiency airflow and low-leakage coupling (without the wrapping of joints).
-
Tubing provides more air, consistently, reliably, farther, with smaller diameters.
-
Tubing efficiencies offer significantly reduced noise levels.
-
Hi-visibility safety green color.
-
Quick-to-install and long-lasting coupling system.
-
Safe to handle – no shards or exposed fiberglass that can cut and no glass particulate in the air.
-
Fire Resistant for mine safety and to meet local codes.
SPECIFICATIONS:
Diameter Range: 16”, 20” and 24” (406, 508 and 610mm)
Standard Length: 10’ (3.05m).
