Abstract
The utility model relates to a steel and porcelain composite pipeline which is an improvement to transport pipelines in heat power plant and mines. The utility model is composed of an outer pipe (2), an anticorrosive liner (3), a porcelain pipe (4), and flanges (1). The anticorrosive liner (3) and the porcelain pipe (4) are sheathed in an inner cavity by the outer pipe (2). Two flanges are respectively welded on both ports of the outer pipe (2). The steel and porcelain composite pipeline has simple structure, strong rot resistance, corrosion resistance, long service life, low cost, smooth inner wall, and easy connection.
Description
The utility model is the technological improvement to thermoelectricity plant and mine conveyance conduit, and its name is called steel porcelain multiple tube.
In the prior art, the conveying of ash disposal of electric power thermoelectricity plant and mill tailings mixing material, the pipeline that is adopted has the steel-lined rubber pipeline, steel lining is moulded pipeline, though these pipelines have the corrosion-resistant characteristics, but wear-resisting property is very poor, working life is short, especially hold for the high-speed friction of the buck of thermoelectricity plant and mill tailings Combination liquid and can't stand, can be very fast expose steel pipe to the liner wearing and tearing, steel pipe easily is worn and erodes, secondly, thermoelectricity plant's ash water ph value shows acid, the Main Ingredients and Appearance of buck is the mixing material of water and cinder, under the effect of water pump, flows in the pipeline high speed, to the tube wall serious wear, because the pipeline life cycle is short, make the pipeline cost become high, this is current puzzled thermoelectric, the difficult problem of mine industry.
The purpose of the utility model design is to avoid the deficiencies in the prior art and a kind of steel porcelain composite pipe is provided, and it is simple in structure, and antiwear property is strong, and is corrosion-resistant, and long service life is cheap, and inner wall smooth easily connects.
To achieve these goals, the utility model can adopt following measure to realize, described steel porcelain multiple tube ecto-entad is made up of outer tube, anticorrosion lining, porcelain tube successively, anticorrosion lining is evenly distributed in the internal surface of outer tube, after porcelain tube and outer tube location was concentric, outer tube sleeve was around the outer surface of porcelain tube.
To achieve these goals, the utility model can also adopt following measure to realize, the gap≤2mm between described anticorrosion lining and porcelain tube are moulded outward, and with within the epobond epoxyn injection gap.
To achieve these goals, the utility model can also have been adopted following measure and realize, described anticorrosion lining can be the plastic-coated lining, also can be glass fibre reinforced plastic coating, the thickness≤10mm of porcelain tube.
To achieve these goals, the utility model can also adopt following measure to implement, and described outer tube is a carbon steel tube, also can be welded tube, also can be Glass Steel Tube.
For making multiple tube be convenient to connect, be welded with flange respectively on two ports of outer tube, flange surface also has anticorrosion lining.
In order to be illustrated more clearly in the utility model, the utility model is done further explanation below in conjunction with drawings and Examples:
Fig. 1 is the partial sectional view of the utility model structural representation.
Fig. 2 is the structural representation of a port of steel porcelain multiple tube described in the utility model.
Among the figure, 1 flange, 2 outer tubes, 3 anticorrosion linings, 4 porcelain tubes
Described steel porcelain multiple tube, form by outer tube 2, anticorrosion lining 3, porcelain tube 4 and flange 1, two ports of outer tube 2 weld a flange 1 respectively, and anticorrosion lining is evenly distributed in the internal surface of outer tube 2 and the surface of the flange 1 that is attached thereto, porcelain tube 4 with outer tube 2 location concentric after, outer tube 2 is enclosed within the outer surface of porcelain tube 4, outer tube 2 is a steel pipe, and designed porcelain tube 4 wall thickness are between 4 ± 1mm, and anticorrosion lining 3 is a coating layer, between coating layer and the porcelain tube 4 the 2mm gap is arranged, can inject epobond epoxyn.
The utlity model has following advantages,
It is simple in structure, and abrasion resistance is strong, and anti-wear performance is strong, and is corrosion-resistant, and long service life is cheap, Inner wall smooth easily connects, outer shock resistance, and interior anticorrosion has solved present electric power steam power plant's ash disposal and ore deposit, mine Slag mixing material conveyance conduit short problem in service life.
