Q:What are the sealing ways of pipe joints? Thank you
The pipe joint is the connecting tool between the pipe and the pipe, and it is the connection point between the component and the pipe. It plays an indispensable role in pipe fittings. It is one of the two main components of hydraulic pipe. The pipe joint is used for straight connection such as instrument, and the connection forms are socket welding or threaded connection. It is mainly used in low pressure pipes with small diameter, used for parts that need to be packed frequently or used as final adjustment of threaded pipe fittings. Fast and easy and related products were included, should adopt the structure of metal surface contact sealing structure, structure of gasket seal is usually used for conveying water, oil, air and other general pipeline, the use of malleable cast iron material. In addition, the use of requirements and prices are also factors to consider when selecting.

when your to drunk to stand you fall over and your safely tucked away in bed and in the middle of the night if you roll out of bed then you just roll the other way and your back in bed again.

Sounds like you want to build a go-cart frame from pipe? If so, you should know that ordinary steel pipe, the type usually used for water, is rather fragile will crack easily for it's weight. Lots of people prefer to use structural tubing which has design and alloy properties that make it better for such things. It will resist bending cracking, but you'll probably have to weld it. If you're talking about very low power and low speed and have a lot of scrap pipe and fittings to play with, then you should think about triangulation. Concentrate on making your frame look like a lot of triangles.
Q:I have 5 1/8 x 3 x 36 in sheets of balsa wood, and I need to make a boat that will move by itself using rubberbands, and I need some help. Any ideas? Thank you.
God is omnipotent. The god can make giant piles of crap disappear, but cannot wipe childhood cancer off the face of the earth? I don't think so. New myth: He had an elevator that lifted the animals poop to the top deck where the rain washed it away. That's where they get the term poop deck. It had nothing to do with the French word for stern.. That's just a coincidence. More importantly, why did the god drown all the innocent children and babies in the world? Seems a tad extreme.
Q:How about the water pipe fittings and millimeters?20mm is 425mm is 6Why
Because, in the past, the workers who used these units were ordinary workers, so that they were easy to operate, and finally became 4 points, 6 points, and so on. In other words, it was also the wisdom of labour
Q:Is the joint of ground heating pipe and aluminium plastic pipe general?
Pb can only serve as the system supervisor, the pipe joint is hot melt joint, and the aluminum plastic pipe can only be the system supervisor. That is, the joint of PEX and aluminum pipe is universal. If your site pipe is PEX, the tube is generic and cannot be generic if it is PERT.
Q:When I was a youngin' in school, they told us that if you pulled the fire alarm, you were sprayed with some kind of ink so they know who pulled it. Is this true, and if it is, isn't it a bit of a hazard in the event of a real fire?
Rockwell - Somebodys Watching Me ? Sure sounds like the song you're describing
Q:Which rod is best for light saltwater use?
I think a key difference between necklaces and a metal rod is that the metal rod is on the inside of your body. In most cases electrical current flow is on the outside of a conductor. This is why people inside of cars and planes are usually unhurt by lighting strikes. The current flows through the outside metal body. Or, If you have ever seen a demonstration at an electrical show where someone stands inside of a cage and the cage is hit by electrical sparks and the person is fine, this is the same concept in action. Referring back to your original question, jewelry is on the outside of you body and is a good conductor and the current will from your body through it, and the electricity then has to flow back through your body to reach ground. There is resistance heating whenever the current has to flow into another medium. This is partly what melts the jewelry and causes the burns. What would happen with a metal rod is harder to guess and would depend alot on whether or not it was raining and your body was soaked, but it is unlikely that that a rod inside the body would have a large current flow through it. It would not be electrically advantages for the electricity to flow from the outside of your body to the inside. The longer the rod get the more likely it is that it would become the path of least resistance and possibly receive current flow. If there was current through the rod, the most severe burn would happen where the current entered the rod and left it.
