Abstract
The utility model relates to a steel-rubber compound tube with a welding joint, wherein, the front part and the tail part of the steel-rubber compound tube provided with the facing rubber are welded with supporting rings; the outer part of the supporting ring is welded with a short sleeve tube whose front end is provided with a sloping port. In such a way, the welding joint is formed. The front end of the short sleeve tube and the flange of the facing rubber of the steel-rubber compound tube are on the same plane. The steel-rubber compound tube is mainly used for conveying the mine tailings of the pulverized coal ash of the heat power plant and the mines. The utility model has simple structure, easy manufacture, convenient connection and long service life and is capable of the long-term use of the pipeline for conveying the pulverized coal ash without the leakage.
Description
The utility model relates to the operation technique and the joint welding technique thereof of steel and rubber compound tube.
The steel and rubber compound tube of the utility model indication is a kind of special Rubber Lined Steel Pipe.It is mainly used in the conveying of thermoelectricity plant and mine pulverized fuel ash and mine tailing.This steel and rubber compound tube and manufacture method thereof belong to patented technology (seeing 88102958.0, thermoelectricity plant's ash disposal system line with rubber pipeline and technology thereof).The characteristics of this steel and rubber compound tube are: in light weight, wear-resisting property is good, long service life (20～30 years), and price is low, easy transportation and installation.Domestic each big thermoelectricity plant and part mine have been widely used in.At present, the connecting means that this two ends have the composite pipe of rubber flange has two: one, and flange connects, and the 2nd, flexible joint connects.This composite pipe overwhelming majority is embedded in underground use, therefore above-mentioned two kinds of connecting means defectiveness.Time permanent bolt meeting corrosion is difficult to guarantee due intensity; Some loine pressure is very big, is connected with flexible joint with flange and need takes some technical measures, has improved cost.If the joint goes wrong, just become leakage point.
The purpose of this utility model is that a kind of steel and rubber compound tube with welded joint is provided.
The utility model is achieved by the following technical solution: the initial and tail sections at steel and rubber compound tube respectively adds a short sleeve.Be welded with a support ring between the outer wall of short sleeve rear end inwall and steel and rubber compound tube; The front end of short sleeve and steel and rubber compound tube facing rubber flange are on same plane.
Structure of the present utility model as shown in drawings.Steel and rubber compound tube (3) initial and tail sections with facing rubber (4) is welded with support ring (2), short sleeve (1) rear end inwall is welded on the support ring (2), have the short sleeve front end of groove and steel and rubber compound tube facing rubber flange on same plane, constitute two welded joints of head and the tail.
Usage range of the present utility model is Dg108～Dg800 pipe.
Using method of the present utility model: the steel and rubber compound tube that will have welded joint is transported to the job site.The line with rubber flange of two pipes is overlapped compacting, and the front end close apposition of sleeve pipe cut is welded by technical requirements then.Imbed and to carry out preservative treatment before underground.The elm ash pipeline of installing so leakage point can not occur, has both made few part pulverized fuel ash extrude facing rubber flange between two pipes because of pressurized, can only rest in the sleeve pipe yet.When treating that it runs up to some, just can not squeeze again.
The utility model has the advantages that, simple in structure, easy processing, easy to connect, long service life can guarantee that ash handing pipeline does not leak.
Accompanying drawing is a structural representation of the present utility model
Press the accompanying drawing structure, process support ring and short sleeve, after the technical requirements welding, line with rubber can be implemented the utility model again.
With φ 180 * 6(millimeter), 10 of long 12 meters steel pipes, short sleeve specification φ 219 * 8(millimeter), support ring φ 18(millimeter long 150(millimeter)), processing sequence is to have welded welded joint, carry out line with rubber, be transported to the scene after the passed examination, 10 steel and rubber compound tubes are welded into one, imbed undergroundly, under the 8MPa pressure conditions, do not have to leak.
With 10 12 meters long, φ 377 * 6(millimeter) steel pipe processes.Short sleeve specification φ 422 * 10(millimeter), support ring φ 22(millimeter), other condition is with embodiment 1, under the 8MPa pressure conditions, do not have and leaks.
Claims (1)
- Steel and rubber compound tube with welded joint is characterized in that head and the tail have a welded joint, and the structure of welded joint is,The rear end inwall that has the initial and tail sections of the steel and rubber compound tube (3) of facing rubber (4) to be welded with support ring (2), short sleeve (1) is welded on the support ring (2), the front end of sleeve pipe of groove and steel and rubber compound tube facing rubber flange is arranged on same plane.
