Are there any specific requirements regarding when to use flexible hoses and when to use flexi-pipes for loading and unloading?

I also want to learn * it. Can someone help explain it? Thank you

Implementation opinions on hazardous chemicals enterprises’ implementation of the \"State Council’s Notice on Further Strengthening Enterprise Work Safety\" 14. Attach great importance to safety management in the storage and transportation stages. Formulate and continuously improve safety management systems for the receipt, storage, loading, unloading, and transportation of hazardous chemicals, and enforce strict controls over the management of such products during storage. Based on the characteristics of hazardous chemicals, appropriate level measurement instruments should be selected to enable dynamic monitoring of the liquid level in storage tanks. Establish an efficient emergency response and rapid fire suppression system for the tank farm ； Strengthen the safety management of hazardous chemical pipelines. For those pipelines that pass through public areas, it is necessary to improve signage, clarify management responsibilities, and establish and implement a regular inspection system. Effective measures must be taken to inform all units and residents along the route about the hazards associated with hazardous chemical pipelines. Strictly prevent the occupation of hazardous chemical transmission pipelines. All special vehicles used for transporting hazardous chemicals by road must have satellite positioning devices with driving record functions installed and in use by the end of 2011. In the process of filling hazardous chemicals in tank trucks, the use of metal universal piping filling systems should be promoted as a replacement for filling hoses; the use of hoses for filling liquid chlorine, liquid ammonia, liquefied petroleum gas, liquefied natural gas, and other liquefied hazardous chemicals is prohibited.

Actually, these two issues are related to safety. Regulations have been established in this regard, and most factories abide by them – after all, it’s not good if something goes wrong, as hose failures are quite common. However, some small factories might still use hoses in pursuit of petty profits, and it is not recommended to do so.

Our company has recently received many orders to handle liquid ammonia, liquid chlorine, and liquefied gas using metal flexible hoses; there are also requests to switch from using liquid ammonia to a metal universal pipeline filling system (flexible hose) for such handling.

Hoses are now used more often, replacing the hoses designed in the past. If you need an electronic copy, please contact me

From a safety perspective, flexible hoses should be used, but many organizations, in an effort to save money and avoid hassle, use regular hoses for loading and unloading, which is dangerous and prone to accidents. Therefore, these regulations are not always followed; it depends on whether the management of the organization gives them due importance.

If it is designed as a hose, then isn’t the distance from the storage tank to the loading/unloading crane pipe too great for a hose? In other words, the distance between my unloading area and the tank area can be smaller

The safety distance should not prevent the use of equipment; in my view, the purpose of maintaining such a distance is to ensure that in case of leaks at the loading/unloading points or if connections come loose or break, the leakage of oil does not cause damage to surrounding facilities and equipment. For this reason, sufficient safety distance should be maintained for both pipe racks and hoses, which also makes it easier to pass inspections.

That makes sense; I’m still wondering what spacing is needed for the hoses
