Is a PE metering tank a custom-made device?
Thread Content
Everyone rushed to help, but I couldn’t figure out which devices were non-standard and which were standard. I asked many people, but their answers were vague. Is a PE tank considered standard or non-standard? Is a carbon steel heat exchanger standard or non-standard? Are the glass-lined extended versions standard or non-standard? It’s really frustrating:L
“\"Non-standard equipment\" refers to equipment that does not adhere to the unified industry standards and specifications established; rather, it is designed and manufactured according to specific functional requirements. And devices whose appearance or performance is not listed in the **device product catalog. It refers to the equipment needed to do something; specific equipment is necessary to carry it out. Its functionality can only meet specific requirements, and it cannot satisfy the needs of other similar devices. Standard devices are manufactured in accordance with **uniform standards and specifications.
Non-standard equipment refers to equipment that is not universal, and it needs to be redesigned for each transaction. However, the design and manufacturing of non-standard equipment still must comply with relevant regulations and standards. For example, shell-and-tube heat exchangers have a unified **standard GB151. However, each heat exchanger differs in terms of form, specifications, material, and structure. Only in a specific industry, when a certain type of heat exchanger comes in a series of variations in terms of form, specifications, material, and structure, becoming a standardized product that does not require repeated design, can it become standard equipment.
