Description

The fixed serial test block of novel oxidized leather mark
Technical field
The present invention relates to stainless-steel tube oxide skin accumulating amount detection technique field, be specifically related to the fixed serial test block of a kind of novel oxidized leather mark.
Background technology
Austenite heating surface tube is the overcritical material commonly used with ultra-supercritical boiler superheater and reheater in fuel-burning power plant, because running temperature is high, interior media is high pressure steam, can produce oxide skin when running one section in after date pipe, oxide skin is stacked into a certain degree, has following harm:
1, the oxide skin accumulation that comes off can cause boiler heating surface overtemperature tube burst;
2, oxide skin causes damage to components of steam turbine;
3, the generation of oxide skin easily makes main inlet throttle-stop valve bite, causes unit outage;
4, oxide skin comes off and easily blocks drain pipe, threatens unit safety operation;
5, oxide skin can affect metal heat-exchange effect;
6, oxide skin peels off meeting serious harm water and steam quality.
Along with power consumption constantly rises, under ever-increasing situation is required to power quality, require also more and more higher to the reliability of generating set, operating maintenance.Thus, shorter and shorter to the maintenance of electric generation equipments time, more and more higher to its maintenance effect requirements.Therefore be necessary to monitor the amount of oxide skin in stainless-steel tube.Before use equipment detects, be generally whether the amount of the oxide skin of not knowing blocking in deferent has exceeded threshold value.Therefore, the content of manufacturing artificial sample to the oxide skin of blocking is needed to demarcate.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, there is provided a kind of novel oxidized leather mark fixed serial test block, it designs for the different accumulating amounts of heating surface tubes in boilers different size and oxide skin, can effectively demarcate the content of oxide skin in the stainless-steel tube of different wall, be convenient to direct vision, shorten detection time, reduce testing cost.
For achieving the above object, the technical solution used in the present invention is: it comprises organic outer glass tube, organic glass inner core, stainless-steel tube oxide skin deposit; Organic glass inner core is arranged on organic glass outer tube; Described organic glass inner core is provided with grooving, and stainless-steel tube oxide skin deposit is filling inner at grooving.
The present invention adopts organic glass outer tube to simulate the austenite heating surface tube of actual power station use, demarcate the thickness of stainless-steel tube according to different thickness, realized the demarcation of stainless-steel tube oxide skin amount by the oxide skin pouring into different content in the grooving gap in the outer tube of coupling and inner core.
After adopting said structure, beneficial effect of the present invention is:
(1) it can effectively be demarcated the content of oxide skin in the stainless-steel tube of different wall, is convenient to direct vision;
(2) it can cover the dimension series of station boiler austenite heating surface tube comprehensively;
(3) it significantly shortens detection time, utilizes magnetic methods to detect, and do not need polishing, clap X ray sheet etc., detection speed increases substantially, and testing cost reduces greatly.
