In the process flow diagrams of chemical engineering projects, partially reused standardized designs are employed, or complete sets of equipment provided by the manufacturer are used
Thread Content
According to 3.2.4 Reuse Design in the \"Uniform Regulations on the Content and Level of Detail in Chemical Process Design Drawings,\" when a standardized design is reused partially within a process flow, or when complete sets of equipment (units) provided by the manufacturer are used, such reused or complete sections shall be indicated in the drawings using a double-dashed line outline. In actual work, some designers from small design firms believe that this equipment is provided by the equipment manufacturers and therefore falls outside the scope of the design ! ! I said, does that mean that when safety accidents occur with these devices, the designers are not held accountable? ! What do you all think? In my opinion, in accordance with the requirements of relevant laws and regulations such as Order No. 36 or Order No. 45, the design of safety facilities for construction projects that follows the principle of \"three simultaneities\" refers to the safety facilities for the entire production facility; safety facilities related to parameters such as temperature, pressure, liquid level, and flow rate of the complete set of equipment also need to be taken into account. It cannot be assumed that just because the complete set of equipment is provided by the manufacturer, the design institute is not responsible for anything! Some people also separate the design drawings for the simultaneous implementation of three aspects in various specialties from the dedicated sections on safety facility design! ! ! It says the design drawings are not at fault; those who wrote the special report are responsible! ! ! People like this can still do design work, which shows just how low the standard of small design firms has dropped nowadays – there’s not even a hint of respect! A pure draftsman! !
It’s better not to complain. If there are problems with the small design firm, why hire them in the first place? Again, the approach adopted by small design firms is probably the right one; this is different from building a computer by yourself. If the equipment is selected by the design institute, such as motorized pump equipment, in case of problems the design institute only plays a coordinating role. For reference.
According to 3.2.4 Reuse Design in the \"Uniform Regulations on the Content and Level of Detail in Chemical Process Design Drawings,\" when a standardized design is reused partially within a process flow, or when complete sets of equipment (units) provided by the manufacturer are used, such reused or complete sections shall be indicated in the drawings using a double-dashed line outline. I would like to ask for an explanation of this provision. It’s true that there is a problem with the equipment itself, as you said. But if the design institute failed to follow the relevant laws and regulations when designing it – for example, failing to include a nitrogen seal in the design of the storage tank or not providing pressure gauges – then whose responsibility is that?
“For example, if a storage tank is designed with a nitrogen seal but no pressure gauge is installed, whose responsibility is that? ” This issue needs to be handled on a case-by-case basis. If necessary, not only a pressure gauge is required, but also a series of supply Protection facilities. Such as the control facilities involved in multi-path supply. For reference.
It’s provided by the manufacturer; obviously the manufacturer is responsible. The design institute doesn’t even sign off on it
Even a large facility like Timi cannot have specialized equipment designed for it, such as complex devices like compressors. Engineering design always involves reference to equipment; in fact, there is no distinction between large and small design institutes! !
