Steel pipes are widely used in high-risk and high-pressure scenarios such as oil, chemical, natural gas, shale etc. If there is some defect steel pipes, it will lead to serious adverse consequences. Applying object detection the field of deep learning pipe weld identification can effectively improve inspection efficiency promote development industrial automation. Most predecessors traditional c...

Objective. The article proposes a method for finite element analysis of pipe-concrete columns in physically nonlinear setting by reducing three-dimensional problem to twodimensional one based on the hypothesis plane sections. Method. equations theory plasticity concrete G.A. Geniev are used. technique was tested comparing solution with calculation LIRA-SAPR software package, as well experimenta...

The article reflects the results of many years’ (since 1972) research of structural, hydrodynamic, thermophysical and mechanical properties of metal felt capillary structures (MFCS) of heat pipes (HP). These structures were made from the discrete copper, stainless steel, or nickel sintered fibres of 0.002 to 0.01-m length and diameter within 20 to 70 μm. They were intended for the HP with shell...

Wake eld studies using calorimetric methods are reported. Measurements show interference between wake elds generated by two bunches. The described technique can be used to determine which elements introduce bunch coupling. Introduction Due to nite resistance and irregularities of beam pipe wall the bunch of charged particles traveling through a beam pipe leaves behind a wake eld. The structure ...

---------------------------------------------------------------ABSTRACT------------------------------------------------------Surface quality of the machined parts is one of the most important product quality indicators and most frequent customer requirements. Metal cutting processes are important due to increased consumer demands for quality metal cutting related products more precise tolerance...

Tubular products in pipe mills are produced by different methods in wide range of sizes and materials for various applications . From simple ERW steel tubes to high quality and expensive seamless tubes, depending on the application, different NDT techniques are used extensively. All these tests are implemented to fulfil the required specification or standard as well as for condition monitoring ...
