There is insulation between the outside and inside wall of a hot water tank. There is also an insulation product that you can get to wrap around the outside of the hot water tank as well. Kit is usually available at any Plumbing or hardware store. Only good for electrical HWT, as a gas tank has a flue and the insulation would be a waste on the outside of the gas tank
No this is not necessary. Install the pipes as per usual. You can insulate the hot water pipes up to two meters or up to two yards from the hot water outlet from the hot water tank to prevent this.

It is a thermal jacket that fits over the tank to insulate it
If the hot water tank is off it is possible. It is also possible for the cold water going to the hot water tank to freeze. Insulate all pipes that are exposed - or let them drip (this is more expensive!)
They should insulate their house before they insulate their hot water tanks because if the house might be cold they would want to turn on their heater and heat the house. If their heater is on with the water tank that would take up alot of energy.
so then you save more money and so you meet the requirements of the national building code.
Your hot water may run out quickly due to a small water heater tank, high demand for hot water, or sediment buildup in the tank. To improve its longevity, you can insulate the tank, lower the temperature setting, reduce hot water usage, or consider upgrading to a larger tank or a tankless water heater.
Insulation keeps heat from escaping. So if you insulate a water heater, it holds heat better, and does not need to reheat the water as often.
If you have a leak on the hot water somewhere in the house and the water input into the tank is not running, the tank will lose it's water. And if it is an electric tank, the elements will burn out. Gas hot water tank should be no problem. Pressure valve does not have to be open.
About 40-70 psi.
Water pipes may be covered with foam rubber to stop condensation dripping from the surface of cold water pipes in warm and damp climates, and to insulate hot water pipes so the water in them does not cool while flowing from the hot water tank to the faucet,
I do not have a hot water tank, so I have never had a hot water tank flush performed.
