The invention relates to an overlaying layer stripping ultrasound detection imaging system of a major-diameter thick-wall pressure vessel, comprising a mechanical scanning device, an upper computer of a control system, a lower computer of the control system, an ultrasound data processing imaging ...
If a cladding is properly bonded to the inner wall of a pressure vessel or pipe, it can be very effective in protecting the wall from external effects and reinforces the wall, especially in the presence of existing cracks. Such a problem has been solved by Nied [6]. He investigated the...
This technology had been applied in welding of circular seams of several thick-wall pressure vessels. The test results of product could completely satisfy the requirements of code and design.关键词: low alloy steel thick-wall pressure vessel double-wire SAW narrow gap ...
shear stress could trigger the development of atherosclerosis, as Strecker C uncovered in his research,Citation7wall shear stress is significantly lower at posterior wall compared to anterior wall of carotid bifurcation. Thus, we chose the posterior wall at bifurcation as ultrasound target place to ...
1) thick-wall pressure vessel 厚壁压力容器1. Several problems about inner wall surfacing technology including technical property demand, surfacing consumables, process and technique key for thick- wall pressure vessel are discussed in this paper. 论述了厚壁压力容器内壁堆焊技术的几个主要问题,其中包括...
In this paper, complete analysis of stresses within the wall of a composite cylindrical pressure vessel subjected to cyclic internal pressure and temperature is studied. At first, equations of stress and strain are obtained with theoretical method and then, distribution of temperature within cylinder-...
Thick-wall columnarAuto-frettageBauschinger effectFinite elementThe theoretic formula for the optimal radius of elastic-plastic junction in auto-frettage thick-wall columnar pressure vessel was deduced, on the basis of the twin shear strength theory, the relationship between the allowable maximal ...

The invention provides a large-aperture and thick-wall joint pipe between a boiler and a pressure vessel. A Dn716*55 reinforced joint pipe of one vessel equipment is called a reinforced joint pipe for short, 35mm of hydraulic pressure allowance is remained according to the original design, a...
The deformation of hyperelastic tube is determined by a strain energy function, which can be found using experimental data.The dimensionless equations are simplified by making long-wave approximation. The resulting set of differential equations were solved using Galerkin expansion by the radial co-...
