Why can’t quick connectors be used under normal circumstances?
Thread Content
I used to work in a caustic soda plant, where most of the control valves were connected using hoses; it was very convenient to replace or modify the quick connectors. But after leaving that company, I didn’t see any other companies using such hoses anymore – they all used stainless steel or copper pipes. In my experience, stainless steel pipes can also loosen over time, and copper pipes are even more prone to deformation. It’s quite troublesome to make changes to them each time. I’m wondering if there are any regulations or other reasons for this.
You must be referring to nylon pipes. According to HG 20510, they can be used, but in environments with corrosive substances, it is better to use stainless steel pipes.

Actually, there are no special regulations; it mainly depends on the agreement between the design company and the client. After all, everyone has their own preferences, right?:) When using nylon hoses or metal hoses, the main consideration is situations where there is vibration between the equipment and the gas supply pipes.
Nylon tubes are prone to aging and damage, and they are not flame-retardant. Quick connectors are easily damaged and have a high failure rate.
It’s for safety reasons; in some emergency pneumatic unloading valves used in accidents, stainless steel is employed
The stability of quick-connect fittings with hoses is not as high as that of steel or copper pipes
The stability of the air supply source is a concern; quick connectors tend to come loose, and hoses age easily, posing a risk of leaks that can disrupt production
