It is revealed through experiments for the first time that the combustion of Fe〓O〓-Al thermite in SHS-gravitational process is mainly controlled by a gas phase reaction.
The concentric tapered pipe/reducing socket's both sides orifice, the center of circle on the identical spool thread, changes the diameter time, by the spool thread computation pipe position's words, pipe's position invariance, generally uses in the gas or the vertical liquid pipeline changes the diameter.
The optimized parameters, such as diameters and the length of pipe were calculated and the result was good, which provides a solid reference for readers who engaged in correlative research.
The technique and equipment used to produce the ceramic lined steel pipe by SHS-gravitational process, especially used to produce the ceramic lined steel elbow and tapered pipe, were systematically studied in this thesis.
By means of modeling the internal high pressure forming finite element model and simulation with finite element analysis software MSC Marc, the basic features of the shaped process and the fluence rules of forming parameters are analyzed.
It is found that Von-Mises stresses of inner pipe and variable-diameter pipe are normally greater than that of outer pipe. The welds between inner pipe and variable-diameter pipe are the places where the Von-Mises stresses are maximal.
The barrel is made up of rapid opening blind flange, barrel base, variable diameter tubing, saddle support, etc.
The concentric tapered pipe/reducing socket is advantageous to the fluid flow, in changes the diameter time is small to the fluid fluid state's disturbance, therefore the gas and vertical mobility's liquid pipeline use concentric tapered pipe changes a diameter.
Different-diameter pipe size head, also called tube diameter at different, used to connect different diameter of pipe or flange diameter changes on.
When the inlet diameter is greater than pump inlet should be installed eccentric adjustable tube.
Eccentric adjustable tube mounted on a flat part to the above, some packed in the following inclined plane.
Pump inlet pipe diameter changes when level, should choose eccentric different-diameter pipe.
Analysis and Countermeasure for Taper Pipe leak in Steam line
The company mainly engaged in stainless steel, alloy steel, carbon steel and other materials of various specifications Elbow, Reducer, links, flange, big bend, for plug-ins and other series products and pipeline pump concrete, concrete pump pipe, the species of the ground tube, horizontal tube, straight tube, conical tube, pipe, adjustable tube, steel clamp, rubber ring, cleaning ball, cleaning column, piston, various models of aircraft fabric pump fittings, various types of belt conveyor and machine fittings, seamless pipe, spiral pipe, valve, such as steel pipe joints and fittings.
In order to adjust the distance between compressor stations or increase the transporation quantity of gas trunk pipeline, it is often necessary to lay a certain length of parallel pipe and variable diameter pipe in nhe design of gas trunk pipeline.
Combining RAGA with the optimization design of multi hole, varied diameter pipe, the authors solved the problem of optimizing multi dimensional parameters at the same time, in which the advanced convergence and easily to run into partial optimization were avoid.
Optimization Design of Multi-hole and Varied Diameter Pipe Based on RAGA
The communicating vessel comprises a horizontal pipe, a fluid supply tank which is communicated with the horizontal tank, and a reducer pipe assembly, wherein the reducer pipe assembly is composed of a slim tube and a fat tube which are communicated with each other; the slim tube is arranged above the fat tube; the slim tube and the fat tube are coaxial; the reducer pipe assembly and the water tank number at least one respectively.
