Explosion-Proof Ventilation Tubes — IMPA 591421-591422

Explosion-proof ventilation tubes are essential for safe local exhaust and supply ventilation in hazardous areas on board tankers, chemical carriers, LPG/LNG vessels, and offshore units. They are used in pump rooms, cofferdams, cargo tanks, and other confined spaces where flammable gases or vapors may be present. These tubes help prevent the accumulation of explosive atmospheres by directing airflow safely, while their antistatic and flame-retardant construction reduces the risk of ignition from static discharge or sparks.

Constructed from PVC-coated fabric with a conductive surface, these ducts offer excellent antistatic, flame-retardant, abrasion-resistant, and corrosion-resistant properties. The flexible retractable design features a thick steel wire helix and an outer black wear-resistant rubber strip for durability and crush resistance. Available in diameters from 200 mm to 600 mm, with standard lengths of 5 m or 10 m (custom lengths from 3 m to 20 m per piece). The stainless steel D-rings at both ends ensure airtight connections and prevent static buildup. This full series covers IMPA codes 591421 through 591422 (2 variants total), each available for individual order at competitive wholesale and retail prices.
