Features of butt welding fittings:

1.       High class materials

Our products only use high class raw materials of carbon/alloy steel pipes made from NKK or MANNESSMANN equipment for ordinary, high pressure, low/high temperature,boiler and other purposes.

2.       Uniform wall thickness and perfectly round

This can be achieved by our particular technical knowhow and our quality control program.

Q:Anybody ever been in a demolition derby?
To say that Christians want to stop scientific research is rubbish. I am a Christian and have taken part in it and have a daughter involved in an international research project at this very moment. Secondly to say that the existence of God has been disproved is one of the most ridiculous statements ever made and no true scientist would ever make such a statement. Now, lightning rods are not magic and don't make the lightning go elsewhere, They attract the lightning and direct it to the ground. I don't have my bible nearby and can't recall Job 36:32 so I don't understand the full intent of your question. Just to say that it was not God that caused any of Job's problems. Read the book and you will see that it was Satan!
Q:Can you set up an alarm on a laptop?
Exhaust piping is commonly made up of carbon steel . You can get carbon steel exhaust piping with and aluminzied coating which tends to protect it from corroding to soon. The next level is 304 stainless which has even better corrosion resistance due to the lower carbon content. On the high end is 314 and 316 stainless. To check the property of the metal stick a magnet on it . If it is carbon steel or aluminized steel the magnet will stick to it. If it is 304 , 314, 316 the magnet won't stick. Dont use a oxy/act system if you are not experienced with it . You will end up torching your car. Use a sawzall / reciprecating saw aloneg with safety goggles for the eyes. Once you figured out your design take the pipe to a muufles shop and have them expand the ends . They will charge you around $20 . Long term savngs compared to the oxy/act system . Its old skool. Plasma cutters are the in thing now

Q:type of drill for jewelry and drilling into small stones ,glass and resin?
If this is the hot water tank temperature pressure relief valve drain line then by code it should be copper pipe no smaller than 3/4 inch in diameter. If you are getting hot water dripping from this line and it is connected to the TPR Valve then the valve is bad and leaking or the valve is doing its job and the water heater is malfunctioning and this is in turn a safety issue. Never cap off the outlet of a TPR valve if you do and if the water heater malfunctions, overheats or over pressurizes it could explode. This line might be your condensate drain line from your air conditioning unit. Best way to repair is to purchase elbow, two couplings and some pipe, PVC primer and PVC glue. Cut out old defective part install new. Use bleach water on mold and leave wall open a few days bleach will kill mold. Pipe and fittings should be minimum schedule 40 PVC pipe. Make sure all joints are glue joints and not compression couplings or unions. Do not install compression couplings or unions in the wall as this is against plumbing code. See link.
