Specifications

Expansion hose have the property of excellent quality, longer cycle life, good reliability and environmental protection.

l Construction: The expansion hose consistd of an inner tube, reinforcement layer,middle layer and rubber cover.

l Feature: the hose body length decreased, the diameter increased and on the expansion state after hose enduring interal upright pressure. Under this condition, the hose accomplishes the hole sealing function.

l ApplicationAplication to coal mine and clear dust

Application to engineering construction and leak prevention construction underground

Application to tunnel exploitation and pour cast underground and underwater
