plain bush bearing embedding technology
plain bush bearingembedded technology is a new technology, a new embedded steel bushing is a major breakthrough in the field of directly buried installation technology, this technology is suitable for use in high underground water level area. 1 it has the waterproof, leakproof, permeability, compressive strength and fully enclosed technical advantages.Steel sleeve steel directly buried insulating pipe has three layers of structure: medium steel pipe, anti-corrosion and supporting role of coat steel pipe, and the conveying pipe between steel tube filled with coat of superfine glass wool composition, including fillers can also be a graphite, silicate clay pipe shell or polyurethane foam. 2 PTFE bronze bushing,PTFE graphite lubricating white lubricant of steel prefabricated directly buried insulating pipe steam is suitable for conveying 2.6 mpa, 360 jiashan bearings degrees centigrade steam or other high temperature medium, because of its outer sheath formed by steel tube, not only high strength, simple construction, maintenance, not easy to damage, and a longer service life. 3 keep the reliability of the groundwater seepage problem is the top issue facing the underground buried pipes, moreover, excellent mechanical strength is also directly buried pipeline problem that nots allow to ignore.Steel sleeve steel directly buried insulating pipe connection because the outer steel tube welding way, so it has very excellent sealing performance, and robustness of outer sheath pipe guarantee steel set of directly buried steel pipeline in the normal operation of the high underground water level area. Purpose: DU oilless dry bushing is widely used in liquid and gas transmission pipeline, chemical pipeline heat preservation engineering, petroleum, chemical industry, the central heating network, the central air-conditioning and ventilation pipes, municipal engineering, etc. |
