How do you conduct leak test to a power transformer?
1. Test Method 1) Breather separated from main body, body clean by Air. 2) Nitrogen(Dry air) through the transformer to the body's respiratory system piping at a pressure of 0.35kg/㎠ injection. 3) Pressurized leakage area and then left in place for 12 hours after the inspection. 4) Record the start of the test, the injection pressure and oil temperature(ambient temperature) will vary depending on the oil temperature and the pressure of nitrogen(N2). 5) If the leakage area in case of a fastening portion and gasket area and re-check the pressure(leaks) to restart the test. (In this case, the pressure holding time is restarted.)
What is the difference between PE80 AND PE100?
from : Engineeringtoolbox.comPolyethylene pipes are also classified by the type of material used:PE 32 - low pressure piping systemsPE 40 - low pressure piping systemsPE 63 - medium pressure piping systems - irrigation system - drinking water connectionsPE 80 - gas pipe for natural gas distribution network with pressure rate up to 4 bars - drinking water pipe with pressure rate up to 16 bar - sewers, outfall pipes, industrial pipesPE 100 - high demands piping applicationsThe Minimum Required Strength - MRS - according ISO 4427 for the different materials are:Designation of materialMRS at 50 years and 20oCMpa (bar)PE 10010 (100)PE 808 (80)PE 636.3 (63)PE 404 (40)PE 323.2 (32)
What size PVC pipe do you use for the main drain line out of your house to the street?
Most of the time it is 4 inch.
Which is better and will last longer when replacing main sewer drain lines - cast iron pipes or 4 PVC pipes if the plumber gave you a 3-year warranty on the cast iron and a 1-year on the PVC?
I can't imagine the plumber only giving 1 year on the PVC. Cast iron is rough on the inside and those rought spots can snag paper, lint, etc, eventually leading to blockage. PVC should last much longer and be less susceptible to blockages from material getting caught on the inside wall of the pipes. Also, PVC doesn't rust, while cast iron will. All-in-all, I'd have to vote for the PVC (make sure that it is at least Schedule 40 PVC).
What is the between PVC and CPVC?
The type of service they are to be used for In a home PVC is used for the drains,the drain vents,main out going sewer line,water supply lines for a boiler/heating system or sprinkler systems. In a home CPCV is used to supply water to sinks,toilets, showers,hot water heater and exterior faucets... Because of the difference in usage there is also a difference in the wall thickness between the PVC pipe and CPVC pipe... So a 3/4 in PVC fitting will not match up to a 3/4 in CPVC pipe and vise versa...

What are the necessary steps to conduct a gas pipe pressure test effectively?
To conduct a gas pipe pressure test effectively, follow these steps: 1. Shut off the gas supply. 2. Connect a pressure gauge to the pipe. 3. Pressurize the pipe to the required level. 4. Monitor the pressure for a specified time. 5. Check for any pressure drops, leaks, or abnormalities. 6. Release the pressure and safely restore the gas supply if the test is successful.
