Thinning width of the elbow for the ultimate load


The thickness of the elbow is not negligible for the ultimate load. Based on the analysis of the finite element, we give the formula for calculating the ultimate pressure of the local thinning elbow, and we find through the calculation of the formula. It is quite consistent and safe with the calculation and experimental results of the finite element, and the calculation formula can also be applied to the safety assessment of the local thinning elbow, which also supplements the gap in the research. In fact, whether it is a pipe or a pipe fitting, the thickness can be within a certain range according to the standard or design requirements. Due to the level and experience of each manufacturer, the on-site product often requires a certain pre-treatment during construction.


This is the latest production process for seamless elbow fittings. This is the most advanced. Compared to the original pressing elbow, the appearance is very smooth and neat. There is no rough surface. After the furnace is burnt red, then proceed The process of tanning is a world apart. It is a very important process parameter to speed up the influence of the advancing speed of the seamless pipe in the production of the elbow on the carbon steel elbow geometry. , directly controlled by hydraulic system flow regulation. Pipe fittings with crimping and backing, which increase the overall strength of the pipe end to the outside or inside of the pipe or to seal the pipe ends. The development and use of these steels is very fast. Because of the good wear resistance and durability of these steels, the production process is relatively simple, the economics are reasonable, and it is applicable under many working conditions, and is welcomed by users.
