Description
Technical field
The utility model belongs to draining conveyance conduit technical field, particularly relates to a kind of buried galvanized pipe for drainage pipe and connection set thereof.
Background technique
Coating Steel Pipe has good intensity, rigidity and anti-press capacity, certain heat resisting and pressure resisting ability, moderate, and raw material are easy to obtain and are easy to processing, and thus the main material of a kind of plumbing is widely used in industrial or agricultural and building internal drainage pipeline; But the requirement for pipeline in the drainage system sour in sewage complicated component and industrial sewage, alkaloid substance content is high is more and more higher, be corroded so common drainage pipe is in use generally easy, the object of Long-Time Service can not be reached, poor corrosion resistance.
Model utility content
The utility model provides a kind of buried galvanized pipe for drainage pipe and connection set thereof, efficiently solves the poor corrosion resistance of original buried galvanized pipe in above-mentioned background technology, the problems such as working life is short.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of buried galvanized pipe for drainage pipeline, by passivating layer, steel pipe, zinc coat, anti-oxidant skin, body seal ring, clip, clip seal ring, slot rolling, body forms, it is characterized in that: described steel pipe inner wall is provided with one deck passivating layer, described outer wall of steel pipe is wrapped up by zinc coat, described anti-oxidant skin is positioned at the outer surface of zinc coat, described two body joints are respectively arranged with the slot rolling matched with body seal ring, described clip is positioned at the top of body seal ring, described clip seal ring wraps clip.
Described passivation layer thickness is 45-50 μm.
Described galvanized layer thickness is 70-75 μm.
Described anti-oxidant outer layer thickness is 90-95 μm.
The beneficial effects of the utility model are:
1, the utility model adopts hot galvanizing bellows, and wall thickness is 5.5,6.5,7.5mm, increases the surface area of body kiss the earth, improves anti-corrosion capacity, extends galvanized pipe working life.
2, the utility model body joint is provided with connection set, and its sealing reliability is high, at body for a long time under elevated pressures state, seepage can not occur.
3, the zinc coat of the utility model outer surface and anti-oxidant skin effectively can protect body, make it more corrosion-resistant, extend its working life further.
4, the outer surface of the utility model steel pipe adopts galvanizing by dipping process, and internal surface is not zinc-plated, and inner-walls of duct zinc coat can be avoided the impact of quality of connection.
5, the utility model joint location is provided with slot rolling, can not destroy zinc coat, avoids joint area to be subject to corrosion, extends pipeline life.
