Pinch valve, chance of cold welding silicone tube

Click For Summary
The discussion centers on the potential risk of cold welding in silicone tubes when used with a solenoid pinch valve, particularly when the tube is pinched for an extended period, such as several months. Concerns are raised about the likelihood of the silicone tube welding at the pinch point under low pressure conditions. The main question is whether the pressure sufficient to stop fluid flow could lead to cold welding and what measures can be taken to prevent this issue. It is noted that excessive force from the pinch could increase the risk of cold welding. The conversation seeks insights or additional information on this topic to better understand the risks and preventive strategies.

Hi everyone,

In a current project, I'm curious about the risk of silicone tube cold welding when used with a solenoid pinch valve, such as = http://cfnewsads.thomasnet.com/images/large/454/454667.jpg

What is the likelihood silicone tube will cold weld at the pinch point, if the pressure is just enough to stop low pressure fluid flow (water), and, if pinched for several months. What are the chances of the pinched area, cold welding? If cold welding is a risk, what can be done to avoid it?

I assumed that an overly strong pinch might cold weld silicone together.

many thanks / simon

Thread 'Ground coffee freshness question'

Somewhat separate from the coffee advice of “buy whole beans, grind fresh at home daily”, I'm looking to understand the factors that contribute to purchased ground coffee losing freshness after opening (oxygen, humidity, temperature, time, other?). I'm assuming oxidation is the main factor, assuming normal room temperature and mid-range humidity. It appears (I'm having trouble finding good info on this) that a high quality modern pre-ground coffee is packaged in a way that maintains...
