Q:The seamless steel pipe is used as an oil pipe, and the oil leakage is often occurred after it is equipped with a clamping sleeve. The main reason is that even if the handle nut is screwed, the clamping sleeve and the steel pipe can not be riveted tightly, and still loosen. Consult: how can the tubing be chosen? The best way to cut pipes? The proper take over procedure? How to prevent rust on tubing surface?
Main reasons and troubleshooting methods of oil leakage in sleeve type pipe joint:The card sleeve type pipe joint with highest accuracy requirements (diameter > drawn tube. When the cold drawn pipe and the sleeve matching parts are not closed, the strain has an axial pin (the outer diameter of the pipe and the inner diameter of the sleeve), it will leak. Solution: at this time can be cut off a strain of cold drawing tube, or replace the card re assembly qualified.
Q:I have a lightning rod pizza oven with specialty pepperoni and mushroom conductors. I am concerned about lightning burning the cheese, however. How can I prevent this? Also, any suggestions for keeping rain from making the crust soggy? Thanks!! :)
I think this is a very bad idea,first ask yourself what are you going to do with the sulfuric acid in the battery?
Q:really though, I think I'd have to run outside naked and if my cellphone was not in reach, use a neighbor's phone to dial 911. Talk about a rush. now the people I know cant even say the only thing I own are the clothes on my back. Is this the right thing to do, to not grab anything on your way out?
Rusty's right. Plumber's language usually refers to the hole in the pipe, or inside diameter, so when we mere mortals measure things, we get waylaid on the outside diameter (OD) and get confused. Any hardware store or building center will have a bin full of 1 1/2 SCH 40 PVC tees - just stay away from the lightweight under-the-sink stuff - which fits 1 1/2 OD pipes So it goes. 75% of the 1/2 brass compression fittings I sell get returned, because nominal 1/2 copper pipe is actually 5/8 OD. etc. By the way, for structural/non-plumbing PVC use, there are specialized fittings that are useful, like couplings without a shoulder inside, so they can slide along the pipe, angled tees with a fourth socket on the side (like for the top end of a tent), or even five or six-socket fittings for hubs, etc. Harder to find, but cool.
Q:A couple of nights ago, the unit started without notice and wouldn't stop until I got the battery out and put it back in.There was no cooking going on at the time.
I'm willing to bet they already knew. If you are ever in his room with the door closed, well, you sure aren't just playing video games or whatever. But hey at least your situation is a little more innocent. When I was 19 I was at my (then boyfriend now husband)'s house when nobody was home. We were in the middle of having sex when the front door opened, and he barely had the time to leap off his bed and throw a pair of pants on. It was his mom who was just like uhh what are you doing? And her shirtless son in the middle of January had to lie his way out of it. I'm pretty sure she figured it out.
Q:My rental car was stolen from right infront of my villa door. I used there phone to call 911 but it wouldn't go through. The front desk told me I have to call their public safety in order for them to relay the message to the police (which I feel is dangerous). I also asked the front desk to show the police, video camera footage from the exits and entrances. And she said they have no cameras by the entrance or exits. Now even though this is a timeshare villa am I within my right to request monetary compensation for their neglegence?Thanks in advance.
I think you got all the gear your going to need. Now you need the motorcycle!
Q:does anybody know a great place online to buy motorcycle or moped alarms?TIA,Luke
obviously you aren't native since you don't seem to know much about the ceremonies. why do you want to mock other people's beliefs? if these really were your beliefs you wouldn't have to ask this on YAyou would have elders to consult. i would never think to take a traditional belief and make it modern .
Q:i went to the pool one time after soccer and forgot my bathing suite. i went swimming w/ my tank and shorts on. haha :)
I speak of personal experience. Is that OK? i) Withholding salary increments and promotion because of personal prejudice base on religious belief. ii) Refusing to grant an increase in salary because of employee honesty. Working for a certain firm as stores manager, I had a lot to do with railway deliveries. Once they incorrectly delivered a drum of pipe fittings which had no address on. I weighed the drum and contacted other firms who bought from the same supplier. I found the correct firm and had the railway collect the fittings - value about $2000.00 - and deliver the drum to the rightful owners. In time the railway personnel asked if I would be able to assist them in the identifying of such unaddressed items. I agreed. On one occasion they sent 9 drums (Est. value $15 00.00 - $20 000.00) for me to identify. The manager of our firm and the accountant saw these on the platform, before I had checked them. He demanded that I tell the railway that all the fittings were ours. There was no manner that the railway personnel would be able to establish the truth. I refused, weighed the drums, and allocated them accordingly. (The other firms were impressed, my manager was not) I was a new employee and after 6 months I approached the Manager with regards to an increase in salary. He refused point blank. I reminded him that a person willing to steal for him, would also be prepared to steal from him. This fell on deaf ears. I was obliged to resign. I could not find other suitable employment, so I started a carpet cleaning business. I was in business about 2 weeks when I was asked to clean that company's office carpets after hours. I suggested I quote for the job before doing the work, the reply was That's not necessary, you won't cheat us. I was handed the keys to the offices and stores and left with my staff to do the work without supervision of any sort. My bill was paid without question. Strange, don't you think?

Q:I wonder if somebody could tell me how CO2 working as a fire extinguisher, regarding that it is full of oxygen?Or, is it possible that there are is some type of substance that is not possible to extinct with CO2.Is it possible that CO2 make an opposite reaction and enlarge fire?
100% How about if the hydrant is broken or frozen. Or heaven forbid that you drop the water pressure so the fire departmant can't put out another fire.
