管道布置经验（Piping layout experience） The arrangement of piping layout is a very careful work, and my experience is as follows: 1, first of all, we should know the function of this section, the number of equipment, the number of pipes and so on, and then according to the equipment layout in mind there is a general direction of the main pipeline, to consider whether the need to set up the middle pipe gallery. 2, but also familiar with the piping standards and specifications, to be very detailed, specific to the adjacent pipe spacing, pipes and similar structures, spacing, pipe frame settings, valve stem height, etc. should know. 3, start drawing, improve equipment layout, control flow chart, start with the line. (when I was drawing more stringent requirements on their own, because if people use CAD not very skilled, the pictures will have deviation, construction cannot be guaranteed, of course the use of 3D Piping accuracy is needed.) Start piping in accordance with relevant piping regulations. 4, attention should be paid to the flow chart, there are special instructions, such as the need for U shaped bend, slope and other requirements. 5, when the tube spacing of adjacent piping, check several points, there are side by side non thermal insulation pipe, flange flange staggered non thermal insulation pipe insulation pipe, flange side tube, flanges staggered, need to see clearly. 6, I think there is also very important, a good designer is a good operator, should always thinking from the operators point of view, to facilitate the operation, this product will not bring trouble to the operation. In the scene also often see, some valves superior, and some valve handle back to people, and so on, can not operate. Replenish oneself: 1 、 piping engineering design content include: device layout design, piping design, pipe, pipe machine (stress analysis); 2, the need to consider the pipe on the control valve group, instrument tube mouth, flow orifice, sampling and heat transfer pipel
