Roughness of the inner wall of the instrument sampling tube
Thread Content
Are there any specific requirements or official regulations regarding the roughness of the inner wall of the instrument sampling tube? I hope everyone can share their opinions on their own products
1. What parameters are measured outside the sampling tube? 2. Even if the sampling tube is rough, it’s still smoother than your short legs covered in hair, right? Gagaga 3: Is it thick or thin? Is it smooth or not? I can’t figure out what you’re trying to do by digging
Then the original poster should speak first. You are involved in the production of precision polished tubes; please first explain to us the technical standards and specifications regarding the smoothness or roughness of your products, as well as the methods used for manufacturing and surface treatment. If you can’t even come up with a simple list of one, two, three, then it’s not interesting at all.
