The utility model discloses a pipeline with carborundum inside lining, the pipeline includes pipeline body and carborundum inside lining, the carborundum inside lining is fixed on the inner wall of pipeline body. The utility model provides a pipeline with carborundum inside lining stable in structure is firm, is difficult for droing, and long service life, and the forming technology of carborundum inside lining is simple, can overcome the short problem of pipeline inside lining life in the past.

Description

A kind of pipeline with silicon carbide lining
Technical field
The utility model relates to pipe technology field, particularly relates to a kind of pipeline with silicon carbide wear-resistant liner.
Background technique
Along with modern science and technology scale high speed development, improve the conveying capacity of the industries such as electric power, metallurgy, coal, oil, chemical industry, building materials, machinery, thus increase the test of pipeline to medium transport ability.Because fed sheet of a media generally has flow velocity soon, the features such as flow is large, and in course of conveying, long-term continuing produces the effects such as impact, wearing and tearing, corrosion to tube wall, pipeline generation fatigue is caused and is gradually worn through.Generally have employed the abrasion-resistant cast steel material of thickening at heavy wear positions such as pipeline reducing diameter, threeway, bend pipes but be just worn at 2-3 month, pipeline just must carry out repairing or changing, have a strong impact on the efficiency of producing, increase the input of production cost and manpower.
For solving abrasion of conveying pipes problem, the past adopts segmentation cutting to conveyance conduit easy to wear, pasting wear resistant ceramic chip, the abrasionproof way of then butt welding recovery.But because the effective storage life of ceramic paster tackiness agent is limited, once adhesive failure, ceramic paster comes off in a large number, causes conveyance conduit Fast Wearing, adds the workload of potential safety hazard and maintenance to power plant.
Model utility content
The purpose of this utility model is to propose a kind of pipeline with silicon carbide lining, has excellent wear resistance.Structural stability is firm, difficult drop-off, inefficacy, and working life extends.
For reaching this object, the utility model by the following technical solutions:
Have a pipeline for silicon carbide lining, described pipeline comprises pipeline body and silicon carbide lining, and described silicon carbide lining is fixed on the inwall of described pipeline body.
Further technological scheme, the thickness of described silicon carbide lining is 2.0-5.0cm.
Further technological scheme, also comprises the coat of paint, and the described coat of paint is on the surface of described silicon carbide lining away from pipeline body inwall.
The beneficial effects of the utility model:
A kind of pipeline with silicon carbide lining that the utility model proposes, pipeline body inwall is fixed with silicon carbide lining, and silicon carbide lining has good corrosion resistance and abrasion resistance, and sound construction, difficult drop-off lost efficacy, and working life extends, and was wear-resisting 2-3 times of watering steel pipeline.
Accompanying drawing explanation
Fig. 1 is the structural representation with the pipeline of silicon carbide lining that the utility model provides;
Fig. 2 is the structural representation of the pipeline body that provides of the utility model and core assembling.
Wherein, 1, pipeline body; 2, silicon carbide lining; 3, the coat of paint; 4, core; 5, fixture block; 6, space.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Embodiment 1
As shown in Figure 1, a kind of pipeline with silicon carbide lining, pipeline comprises pipeline body 1 and silicon carbide lining 2, and silicon carbide lining 2 is fixed on the inwall of pipeline body 1.
The thickness of silicon carbide lining 2 is 2.0-5.0cm, and thickness is moderate, has good corrosion resistance, good forming effect, but is not limited thereto thickness range.
As shown in Figure 1, pipeline also comprises the coat of paint 3, the coat of paint 3, on the surface of silicon carbide lining 2 away from pipeline body 1 inwall, can be protected pipeline and silicon carbide lining 2 further, can also reduce the flow resistance of pipeline internal medium.
The above-mentioned moulding process with the pipeline of silicon carbide lining, comprises the following steps,
Step one, makes core 4 according to pipeline body 1;
Step 2, is fixed on core 4 in pipeline body 1, is fixed, as shown in Figure 2, forms space 6 between core 4 and pipeline body 1, for cast between core 4 and pipeline body 1 by fixture block 5;
Step 3, cast: the mixture pouring into a mould silicon carbide castable and water in space 6, wherein, the addition of water is 5.5 ~ 6.2wt% of silicon carbide castable, and the performance of the silicon carbide lining 2 formed afterwards is good, difficult drop-off, corrosion resistance and flushing resistance good;
Step 4, through overcuring, forms silicon carbide lining 2 in pipeline body 1, wherein, the environmental conditions of solidification is normal temperature and pressure, and curing time is two days, then carries out the demoulding, after the demoulding completes, to liner carry out air-dry, repair burr or spray paint, make pipeline more perfect, be convenient to application.
Preferably, the material of fixture block 5 is silicon carbide, and through cast, solidification, fixture block 5 is fixed in silicon carbide lining 2, and form one with silicon carbide lining 2, even structure, in order to avoid fixture block 5 place of silicon carbide lining 2 is not corrosion-resistant.
Carry out pump-down process after cast in step 3, pump-down process is exhausted by shake unit, can also select other exhaust modes, makes silicon carbide lining 2 close structure, and discharge oxygen, decay resistance is better.
Embodiment 2
The present embodiment is substantially identical with the structure with the pipeline of silicon carbide lining of embodiment 1, and pipeline comprises pipeline body 1 and silicon carbide lining 2, and silicon carbide lining 2 is fixed on the inwall of pipeline body 1.
Difference is, the type of pipeline, shape, size are not limit, and the thickness of silicon carbide lining 2 is not limit, and have good wear resistance, difficult drop-off lost efficacy.
Obviously, above-described embodiment of the present utility model is only to clearly demonstrate the utility model example, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all mode of executions.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
