Abstract
The invention relates to the technical field of weld X-ray flaw detection of butt joint of boiler header pipes, in particular to a header flaw detection pipe sleeve structure which can well realize safety detection of header pipes.
Description
Technical Field
The invention relates to the technical field of weld X-ray flaw detection of butt joint of header pipes of boilers, in particular to a header flaw detection pipe sleeve structure.
Background
The boiler consists of a Cheng Shuichan steam boiler and a boiler for generating heat energy by combustion, the heat energy of combustion needs to be transferred to water in the boiler, and enough heat transfer area is needed, so that the heat transfer area is enlarged, and the drum type boiler is developed into a tubular type boiler to increase the heat transfer area. The water in the tube bundles must continuously and circularly absorb heat energy and separate steam to collect on the upper part of the box (tube), the water below the bottom flows into the box (tube) below and is distributed to each tube bundle to continuously absorb heat in the furnace, and when the welding seam X-ray flaw detection is performed on the boiler header pipe, the inner diameter of the detection sleeve and the maximum outer diameter of the detectable header are limited in the original flaw detection lead room, and the header pipe is easy to rub or collide with the inner wall of the detection sleeve in the flaw detection process, so that damage is caused.
Disclosure of Invention
In order to solve the problems, the invention provides a header flaw detection pipe sleeve structure which can well realize the safety detection of a header pipe.
The technical scheme is as follows: the utility model provides a pipe box structure of detecting a flaw of collection case, its characterized in that includes the straight seam welded tube, straight seam welded tube one end fixed connection taper joint, the other end is opened there is the installation breach, fixed mounting has the flange circle on the straight seam welded tube, straight seam welded tube with the taper joint outside all wraps up there is the lead board inoxidizing coating, the opening part fixed mounting of taper joint has the lead curtain fixed plate, install the lead curtain on the lead curtain fixed plate.
The mounting notch is further characterized by comprising an upper lower notch and a lower large notch, and the size of the conical joint opening is 30 degrees;
the lead plate protective layer is a layer of lead plate with the thickness of 16mm or two layers of lead plates with the thickness of 8mm which are overlapped together;
the lead curtain is fixed on the lead curtain fixing plate through a pressing ring and a first bolt;
and the flange ring is provided with an annular lead plate through a second bolt.
After the structure of the invention is adopted, the outside of the straight seam welded pipe is wrapped with the lead plate protective layer, one end of the straight seam welded pipe is fixedly connected with the conical joint and is sealed by the lead curtain, the flaw detection pipe can not contact with the inner wall of the pipe sleeve when extending in, the radiation leakage is effectively prevented, and the safety detection of the header pipe is well realized.
