Supply PU PU duct vacuum tube factory direct Keywords: PU air hose, PU ventilation pipe, PU exhaust pipe, PU vacuum tube, PU air vacuum tube materials imported from Germany, their abrasion resistance, flexibility is very Well, the carrying capacity of its products, outstanding impact resistance and shock absorption, low temperatures the tube will not harden, become brittle, affect product performance of the play, there will be no long-term use tube stripping phenomenon, affecting the tube conveying liquid ingredients. Transporting sand will not scratch the wall, resulting in a rigid tubular body functional damage, the impact tube use, while the light in the tube, the case of thin wall, wear pvc material wing nearly 10 times higher than the The maximum expansion ratio is 4:1, the bending radius is approximately equal to 3 OD, copper spiral steel frame enclosing the tube to ensure the compressive strength, the tube will not produce in the course of deformation or rupture. Tube transparent, smooth wall, transmission fluid and smooth, conveying the situation clearly visible. Under normal circumstances you can use a polyester-type material, and take special liquid, such as drinks, etc., we recommend using polyether by PONY detection and detection in seized homes, meet food grade standards. Conventional wall thickness of 0.6, 0.9, unconventional wall thickness can be customized, 100 m from the set specifications diameter :25-400mm temperature at -30 ℃ to +90 ℃, short time up to +120 ℃ production lines imported from Germany, high pressure Quick extrusion, to ensure product transparency, uniform thickness, no bubbles glistening, tear, the performance standard is mainly applied to the friction of the tube strong, low temperature flow big, liquid special occasions, such as the high rate of wear flowing strong force particles, sand, gravel, fine, useless glass, dust and chips, gas and liquid environments, silo transportation, etc., are widely used in the glass industry, wood industry, steel industry, plastics industry, mines, shipbuilding, cement industry and other mechanical delivery tube, when the resilient protective hose, especially suitable for machinery and equipment, the dynamic swing position. Expensive imported raw materials, production, sophisticated technology, sophisticated recipes, as well as various costs of the production process consumes, we try to save costs, but we are more insistent quality assurance, to provide you with truly trustworthy product! Packaging: woven Reel facilitate long-distance transport.
