This is a hydrogen pipeline system setup – why are there so many pipes and valves?

It ensures that the hydrogen pumped by the diaphragm metering pump is not affected by purity. The number of pipes and valves in online analysis equipment is often enough to trigger agoraphobia in sufferers.

Build with blocks, add sand, make it complicated – confuse you like that,,, only in this way can it be sold at a high price, and it also helps to prevent thieves from copying it. . . . Westerners and Chinese have fundamentally different ways of thinking. For example, foreign barbers charge high prices; by taking their time to style a few clients per day, they can earn enough to support themselves and even have some left over. Chinese barbers charge very little; they are extremely busy all day long, wishing that everyone in the world would come to them for haircuts. :Lol, foreigners are very protective of their technology; the barriers to entering this field are quite high. In a small town, there’s a set limit on the number of doctors and barbers available. Chinese people place great importance on economies of scale; the entry barrier to this industry is low, but those in power use low prices to drive most people out of the business. {:2_45:}

It’s possible to do this; in the engineering work I do, there are similar modular devices that have just been successfully applied in practice – namely a chemical analysis system for very complex process media with numerous pathways. The demonstration project was still carried out through on-site installation; after debugging, it is now manufactured in its entirety by the manufacturer for subsequent projects. The project is not currently available online. At the beginning of the project, everyone complained about the high difficulty and the challenges in coordinating between the process and instrumentation teams. However, it was found during the actual design process that although there are certain difficulties in 3D design, sufficient possibilities still exist. In fact, many times it’s not that anyone forces you to a certain limit; it’s not absolutely difficult – for example, there may be insufficient space for layout, or manufacturers might need a compact design in order to enter the market, and so on. As for the quantity and use of pipe fittings, it is often a matter of engineering convention and style. Some industries are accustomed to and adapted to butt welding, while others only rely on socket welding ； In some cases, connectors of sufficient quality can be used; in other cases, using cheap connectors will result in leaks, and so on. This is not an absolute issue.

The advanced basic industries in foreign countries are currently beyond the reach of domestic industries.

Considering aspects such as self-control, interlocking, and intrinsically safety, the process is so rigorous that virtually no flaws can be found; this is also something we need to learn.

The key is to be willing to pay for the device; if one is willing to spend the same amount on similar devices produced domestically, those can also be made at home

How many more years will it take for Chinese technology to catch up?

In an environment where low bids are the norm in the domestic market, even if domestic engineers have their own ideas, they end up giving in to pressure from the sales team and continuously reducing the specifications. From a technical perspective, product design is complex in order to meet various requirements of end-users. On the one hand, domestic owners may not be able to outline very detailed requirements; on the other hand, they are likely to be unwilling to incur excessive costs for events with a low probability of occurrence.
