Q:How are plastic tubes measured?

Plastic tubes are typically measured by their outer diameter and sometimes by their wall thickness.

Q:What are the disadvantages of using plastic tubes?

One major disadvantage of using plastic tubes is their environmental impact. Plastic tubes are often made from non-biodegradable materials, contributing to the global plastic pollution crisis. Additionally, plastic tubes require significant amounts of energy to produce, increasing carbon emissions and contributing to climate change. Furthermore, plastic tubes can be prone to leaching harmful chemicals, such as BPA, which can pose health risks. Finally, plastic tubes are less durable than alternatives like metal or glass, making them more susceptible to wear and tear, leading to frequent replacements and increased waste generation.

Q:About plastic drain pipe expansion joint

The setting of the expansion joint of the transverse pipe is that the transverse branch pipe and the transverse dry pipe are connected without the confluence pipe and are connected with the vertical pipe. When the length of the pipe section is larger than 2.2M, the expansion joint is arranged at the side of the cross pipe near the confluence pipe. When the drainage tube is arranged in the inner tube, setting expansion joints in the lateral wall near the well. The other side of the expansion joint of the transverse pipe should be provided with a fixed support.

Q:how do you get 2 pieces of plastic tube unstuck?

Try this, make one end cold and the other end hot. The cold pipe will contract and the warm pipe will expand, making it easier to separate.

Q:How to connect the plastic pipe and the steel pipe joint?

The plastic pipe is outside and the steel pipe is inside

Q:Why should the residential outdoor drainage pipe be preferential for underground drainage plastic pipes? What's the harm of using precast concrete pipes?

The prefabricated concrete pipe has the advantages of large weight, multiple joints, poor tightness, easy leakage, easy pollution to underground water sources, easy crushing, easy corrosion and short service life.

Q:I got a new syrian hamster two and a half days ago, he has a big wire two storey cage with plastic tubes connecting the upstairs and downstrairs, he's spent mostly all of his time in the tube, taking all the bedding from his little house and his food in it and pooing a lot, I mean the tube is full of poo mixed with food and bedding. (I know this is normal) he's still really shy, he spooks easily, and he's not even been on his wheel yet but he's slowly coming around to me when I hand feed him, I haven't touched him yet though, just leaving him to it for a few days. Should I clean his tubes or is it too early? I don't want to stress him out but I read you are supposed to clean his cage every week and spot clean and clean his toilet area every day and his tubes are his toilet area and I'm seriously not joking when I say he poos a lot.

I think that you should probably clean it out. Do it at night when he is not in the tubes so you do not disturb him. My hamster sleeps in an attachment that goes on the tubes and she does the same thing with the food, pooping, and peeing in there. She loves when I clean it out for her, I do it about every 2-3 days. If I do not clean it out and wait an extra day if I am busy or something she takes all of the bedding out of it and moves it to the regular cage area herself. So yes I do think that you should clean it, he will probably appreciate it!

Q:Just curious . . . Seems like it would less expensive and safer.

Maybe the gas reacts with plastic. Glass is non resistant to acids and corrosion.

Q:I have a pond pump and standard aquarium plastic tubing. I will be drilling tiny holes in equal increments throughout the tubing to release the air. Is there an equation to show the air pressure that will be released through the holes? I would like to know how many holes I need and how far to space them to achieve a certain amount of air pressure to be released from a specified length of tubing.This is a test and will not be done under water. A simple diffuser will not work for this application.Ideally I would like a formula where I can input the following and get a result:Tube LengthTube DiameterPump PSITube Hole SizeTube Hole QuantityTube Hole SpacingResultAirflow per Tube HoleAny help would be greatly appreciated. If you need more information please let me know.Thank you,

Well, I suppose it could be done, but you would need the pressure at each hole,which is decreasing as the tube length and water depth. And you have so many variables! I also like to calculate such things as you are doing, but this is really over the top! Here is what I would do; Get a measured paper cup (say 1 cup, or 1/4 litre). Experiment with various sizes and number of holes in your tubing, then hold the cup over the coiled tubing, under water at required depth, with air pump running. Measure the time to fill the inverted cup with air. If a 1/4 litre container fills with air in 15 seconds (1/4 minute), you know you are getting 1 litre per minute. Then try other hole configurations to get what you want. This would be more fun, more practical, and will give bettter results. Good luck Bill

Q:He keeps biting it. Im starting to worry because if he bites a lot isnt it dangerous? Please help. He already bit before.

I would recommend getting some chew blocks for him to prevent the biting. Hamsters teeth never stop growing! some getting some chew blocks would be advisable. Any questions regarding hamsters?. Feel free to email me, my email is on my profile.
