Supply of ductile iron tee

Ductile iron pipe is a slide-T-type flexible interface. It is now widely used in the following DN1000mm casting, has a simple structure, easy installation, sealing better advantage; able to adapt to a certain base modification, it has a seismic capacity. T-type interface utilizes a rubber seal to keep water from sealed. T-type flexible interface characteristics: good sealing performance, the rubber ring by squeezing the inner socket surface and an outer surface of the socket, get sufficient air tightness and water tightness. Corrosion-resistant. Electrical corrosion resistant, due to the connection with a rubber ring seal between ductile iron pipe, rubber ring has an insulating effect, ductile iron pipe than steel has good resistance to galvanic corrosion; acid corrosion, due to the ductile iron pipe outer surface sprayed with a layer zinc, the zinc layer and paint, soil erosion in various sour material has good resistance, steel does not have these, so ductile iron pipe than steel long life, generally 50 years --70 years. Ensure water quality, since the ductile iron pipe inner surface layer of cement lining does not cause oxidation and oxygen in the air or water, and by the health department inspection before, prolonged use of the same quality. Inner pipe surface without any protection, long-term use is easy to air or oxygen in the water oxidation occurs, resulting in harmful substances. Short construction period, using simple tools (brush, wire rope, a variety of pulleys, sling). After the pit dug, the pipe installed into the pit, direct backfill, no other construction. 3 APPLICATION for gas, water, such as water pipe network transformation, municipal pipe network transformation, industrial water transportation and other liquid (wine) delivery.
