Description
Technical field
The utility model is related to pressure vessel angularity measurement apparatus, it is adaptable to which chemical industry, petrochemical industry and nuclear power field are used
Pressure tight seam angularity measurement.
Background technology
In welding process, container each several part is heated uneven, so each several part deformation is also differed, the position being heated occurs
Expansion, but other positions are not due to being heated, then will not deform, and then welding seam part branch is compressed by other parts, is compressed to
Mecystasis, outwardly convex.At the end of welding, this part can cool down and shrink again, become to cave inward.So as to form container
Weld degree.The corner angle size (abbreviation angularity) that weld seam is formed is a kind of than more serious manufacturing defect.The presence of corner angle,
The linearity of container can be influenceed.If low pressure tower, then influence bigger, because tower type container is disposed vertically, corner angle meeting
It is not completely vertical to cause container, influences the stability of tower type container, or the installation of other workpiece is also resulted in has a strong impact on.
In addition, the presence of angularity can cause cylinder linearity not meet the requirement of manufacturer's standard, tube structure is set not connect
It is continuous to produce additional bending stress when container Inhaul operation so as to increase local stress, corrosion resistant apparatus may be triggered
Stress-corrosion cracking.Meanwhile, the presence of angularity is easy to make weld reinforcement exceeded, causes obvious partial structurtes discontinuous,
And cause stress concentration very high at reinforcement, so that the fatigue life of weld seam is decreased obviously, directly affect pressure vessel
Workmanship and performance, the safe operation to equipment bring hidden danger.
It can be seen from the regulation in GB150, if weld degree is exceeded or weld seam has other defect, it is necessary to this weldering
Seam and its impacted region of surrounding carry out the measurement and calculating of stress, and the container to there is angularity carries out safe evaluation.This
