Greatly；On the other hand it is equipped with plastic inner pipe in order to solve because the problem of stainless steel welded inside pipe wall corrosion-resistant is standing, but
Plastic inner pipe differs too big with the linear expansion coefficient of stainless steel welding tube, the fault such as delamination or interior pipe explosion easily occurs.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, it is provided that a kind of stainless steel welded
Pipe.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is to be achieved through the following technical solutions:
A kind of stainless steel welding tube, including welded tube body, is provided with internal lining pipe in described welded tube chamber body, described welded tube is originally
The two ends of body are provided with welding those widened sections, and the thickness of described welding those widened sections is equal with the wall thickness of welded tube body；Described internal lining pipe divides
For interior rubber tube and outer plastic tube, the outer wall of described interior rubber tube offsets with the inwall of welded tube body, outside described outer plastic tube
Wall offsets with the inwall of interior rubber tube, and described interior rubber tube and outer plastic tube are provided with and opening of welding the cooperation of those widened sections thickness
Mouthful, the pipe thickness sum of described interior rubber tube and outer plastic tube is equal with welding the inside protrusion length of those widened sections.
Further, 1.5～3 times of a length of welded tube body wall thickness of protrusion that described welding those widened sections is inside.
Further, the lateral surface of described welding those widened sections is electroplate with resistant material.
Further, the wall thickness of described interior rubber tube and outer plastic tube is equal.
Further, described interior rubber tube and outer plastic tube connect by heat-resistant adhesive is fixing.
In this utility model, two ends by one block of steel, are bent to form welding those widened sections first with bar folder by welded tube body,
Offseting when being sized to so that two welding those widened sections docking of bending angle, then made, then by interior rubber by curling, welding
Pipe and outer plastic tube connect formation internal lining pipe, refill in the inner chamber being fitted on welded tube body.
The beneficial effects of the utility model are:
1, by arranging welding those widened sections, both convenient welding, improve again the structural strength after welding；In internal lining pipe is divided into
Rubber tube and outer plastic tube, interior rubber tube and outer plastic tube be provided with and weld those widened sections thickness coordinate opening, when conveying heat/
During cold medium, interior rubber tube and outer plastic tube expanded by heating/by cold events, due to the design of opening, do not have and delamination occurs
Or the fault such as interior pipe explosion.
2, the corrosion resistance of outer plastic tube is preferable；Interior rubber tube has insulation, buffering effect, it is adaptable to long distance delivery.
Certainly, implement arbitrary product of the present utility model to it is not absolutely required to reach all the above advantage simultaneously.
