The invention discloses a kind of thin-walled liner steel pipe, including steel pipe, concrete sleeve, positioning pipe, connecting tube, ring flange and blind plate, the positioning pipe and connecting tube are made of integrally formed steel plate, positioning pipe is fixed on the end of concrete sleeve, connecting tube is connected between ring flange and concrete sleeve, the outside diameter of connecting tube wherein one end is more than the outside diameter of the other end, and the thinner one end of connecting tube is fixedly welded on the edge of ring flange, is bolted between blind plate and ring flange.Relative to the prior art, thin-walled liner steel pipe of the present invention has the advantage that：This special blind plate blocks up, and thin-walled steel internal lining pipe and outer tube can be connected into an entirety, during bulge test is carried out, make at blind plate and with outer tube joining place uniform force, so as to smoothly complete pipeline bulge test.
Description
Technical field
The invention belongs to stainless steel tube field, more particularly, to a kind of thin-walled liner steel pipe.
Background technology
Underground piping is one of big event in economic construction of China.Found the state and add up the ground for being laid with more than 380,000 kilometers over 60 years
Lower water supply line, most of to have arrived the end of term of being on active service, for some discovery leakage rate of water supply up to 20% or so, this part underground utilities is anxious
Reparation need to be updated.At present, with expanding economy, the scale of domestic city is increasing, for the needs such as water delivery, draining also with
Increase.The many water supply and sewerage pipelines of urban inner are long neglected and in disrepair, and leak is serious, and some is as source water pipeline, if laying again
Duration is longer, and earth clearance intricate operation.Damaged pipe is repaired using internal lining cutting thin-wall stainless steel or steel pipe,
There are more and more engineer applications.However, to ensure that conveyance power of water, stainless steel and steel pipe carry out liner using sheet-metal duct,
Therefore it is at blind plate and weaker with outer tube joining place, it is therefore desirable to which that special blind plate blocks up when sheet-metal duct is suppressed.At present
The blind plate suppressed for thin-walled liner steel pipe there is no to block up both at home and abroad.
The content of the invention
In view of this, the present invention is directed to propose a kind of thin-walled liner steel pipe, can solve the above problems.
To reach above-mentioned purpose, the technical proposal of the invention is realized in this way：
A kind of thin-walled liner steel pipe, including steel pipe, concrete sleeve, positioning pipe, connecting tube, ring flange and blind plate,
The positioning pipe and connecting tube are made of integrally formed steel plate, and positioning pipe is fixed on the end of concrete sleeve, and connecting tube connects
It is connected between ring flange and concrete sleeve, the outside diameter of connecting tube wherein one end is more than the outside diameter of the other end, and connecting tube is thinner by one
End is fixedly welded on the edge of ring flange, is bolted between blind plate and ring flange.
Further, some location holes are evenly equipped with the positioning pipe, rivet is fixed on concrete sleeve by location hole
End.
Further, the connecting tube is cut into be welded to each other again after some steel bars for steel plate and is made, the surface of each steel bar
Product size is identical.
Relative to the prior art, thin-walled liner steel pipe of the present invention has the advantage that：This special blind plate blocks up,
Thin-walled steel internal lining pipe and outer tube can be connected into an entirety, during bulge test is carried out, sentence blind plate
And with outer tube joining place uniform force, so as to smoothly complete pipeline bulge test.
