Abstract
The invention discloses a novel thin-walled lining steel pipeline. The novel thin-walled lining steel pipeline comprises a steel pipe, a concrete sleeve, a positioning pipe, a connection pipe, a flange plate and a blind plate. The positioning pipe and the connection pipe are formed by integrally-formed steel plates. The positioning pipe is fixed to the end portion of the concrete sleeve. The connection pipe is connected between the flange plate and the concrete sleeve. The outer diameter of one end of the connection pipe is larger than that of the other end. The thinner end of the connection pipe is welded and fixed to the edge of the flange plate. The blind plate and the flange plate are fixed through bolts. Compared with the prior art, the novel thin-walled lining steel pipeline has the beneficial effects that by means of a specially-manufactured blind plate plug, a thin-walled steel lining pipe and an outer sleeve can be connected into a whole; and in the bulge test process, stress of the joint of the blind plate and the outer sleeve is uniform, and therefore a pipeline bulge test is smoothly completed.
Description
Technical field
The invention belongs to stainless steel tube field, especially relate to a kind of New Thin-walled liner steel pipe.
Background technology
Underground piping is one of big event in China's economic construction.Found the state and add up over 60 years to lay 380,000
The groundwater supply pipeline of many kilometers, major part has arrived the military service end of term, and some discovery leakage rate of water supplies reach
About 20%, this partly underground pipelines urgent need renewal reparation.At present, along with expanding economy, state inner city
The scale in city is increasing, needs to be consequently increased for water delivery, draining etc..Urban inner many discharges
Waterpipe is long neglected and in disrepair, leaks serious, have as source water pipeline, if again laying, the duration is longer,
And earth clearance intricate operation.Internal lining cutting thin-wall stainless steel or steel pipe is used to repair damaged pipe,
There is increasing engineer applied.However, to ensure that conveyance power of water, rustless steel and steel pipe all use
Sheet-metal duct carries out liner, therefore when sheet-metal duct is suppressed, at blind plate and with trocar sheath joining place ratio
Weaker, it is therefore desirable to special blind plate blocks up.There is no both at home and abroad at present and suppress for thin-walled liner steel pipe
Blind plate block up.
Summary of the invention
In view of this, it is contemplated that propose a kind of New Thin-walled liner steel pipe, can solve above-mentioned
Problem.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
A kind of New Thin-walled liner steel pipe, including steel pipe, concrete sleeve, positioning pipe, connecting tube,
Ring flange and blind plate, described positioning pipe and connecting tube are made up of integrated steel plate, and positioning pipe is fixed on
The end of concrete sleeve, connecting tube is connected between ring flange and concrete sleeve, connecting tube wherein
The external diameter of end is more than the external diameter of the other end, and the thinner one end of connecting tube is fixedly welded on the edge of ring flange,
It is bolted between blind plate and ring flange.
Further, described positioning pipe being evenly equipped with hole, some location, rivet is fixed on coagulation by hole, location
The end of soil suite pipe.
Further, described connecting tube is to be welded to each other after steel plate is cut into some steel bars to make again, Mei Gegang
The size surface area of bar is identical.
Relative to prior art, New 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 trocar sheath can be connected into an entirety, beats carrying out
During pressure test, make at blind plate and with trocar sheath joining place uniform force, thus smoothly complete pipe
Road bulge test.
