How many of the devices in each of your installations are imported?

Imported products are better than domestic ones; how many of everyone’s installations use imported equipment?
Coking unit, radiation pump, four-way valve
Almost all of our equipment is domestically produced; only the butterfly valve of the smoke extractor is imported, which is why there are constant problems.
Almost all of the high-pressure valves in our small hydrocracking unit are imported from the United States!
The torch control valve is of American manufacture; domestic ones are prone to internal leakage； The motor of the feed pump from Siemens is 17 years old; no one has ever taken it apart, and it’s in excellent condition
Our plant was established in 1990 for coke production; the radiation pumps, high-pressure water pumps, compressors, and four-way valves are all imported (it is assumed that modern coke production facilities use domestic products nowadays)
Here, most of the large-scale and important equipment is imported, such as compressors, furnace tubes, etc
The air compressor is from ELIOTT; many of the valves are imported, and there are also some pumps
The waste heat boilers, furnace tubes, burners, collection pipes, and control valves for the lining of our hydrogen production plants are imported
ELIOTT’s compressors are pretty good. Very durable. The auxiliary pump for the reaction and the passivation agent pump – the pumps are of good quality, but they’re too expensive; a single diaphragm costs over ten thousand. It’s more expensive than a domestic pump. The foreigners take all the money.
I have very few imported devices here; just a few items
High-pressure pumps, compressors, and the like are all imported
We refurbish and regenerate various fans, electric heaters, as well as some special valves, along with reforming feed plate-type heat exchangers.
The catalytic ones seem to be those 2 steam turbine pumps; the rest are probably domestic
The catalytic ones seem to be those two steam turbine pumps; the rest are domestic-made. Oh, and our old catalytic units were also models that were phased out in Canada in the 1950s – they were enlarged by cutting and then welding, and they worked well. I heard that the thickness of those steel plates is hard to specify, but they are very sturdy
Our compressors and turbines are from Siemens, and the slurry pumps are also imported from Germany.
The flare control valve at the inlet of our compressor, as well as the compressor inlet isolation valve, are imported from Italy; several other control valves are imported from South Korea
