Discussant p20130707 has been engaged in demand matching and technical support for process piping in the petrochemical industry (centrally used in FPSO, FLNG, LNG, VVLC) (valves\flanges\elbows\tee\reducers\socket fittings\pipes\pipe fittings, etc.). I hope to discuss issues with all friends and learn from each other.* , People who make progress together live and learn, weekly online time: More than 8 hours. If there are special circumstances and I do not reply in time, I may be out of town or have something else to do, so please be patient. I will reply promptly after seeing it. If there are any mistakes, we tolerate each other and make progress together! If I, Haichuan, are not online and are anxious about the questions I raised, you can contact me on WeChat and indicate Haichuan. If you need any technical information, please describe the requirements clearly and send it to me. As long as it is within my ability, I will try my best to help.

Because some data exceeds 100M, it cannot be uploaded. If necessary, add wei * n

Send some pictures of the products we make. A: The "Dummy Spool Piece" by definition is intended to replace something else and therefore should have the same length as that other item. B: All control valve complete with actuator and instrument, safety relief valves, bursting discs and other fagile items shall be removed or isolated re-installed later. Dummy spool piece may be used to replace valve during test. Usage scenario 1: For some equipment, pipelines, and pipe sections that cannot be installed in time or catch up due to special reasons such as arrival or construction, temporary dummies can be installed at their locations according to the actual size (of course, there is no need to make a one-to-one model, haha). This can ensure that the construction continues without delays or delays due to the aforementioned reasons. Usage scenario 2: Since individual equipment or components are relatively expensive, in order to avoid damage during installation, transportation, and commissioning, dummy parts are installed instead to ensure the smooth progress of debugging. Temporary connections and temporary substitutes for equipment or pipelines are generally called "pipe section dummies" or "pipe section dummies."
