Is there anything available that can be used for internal spraying lining of long sections of pipe with many bends?

For such internally sprayed lining pipes: a long, winding steel pipe with elbows is first installed; after it is cleaned, tools such as robots or endoscopes are used to enter the inside of the winding pipe to carry out the internal spraying process. Once the coating has cured, the lining pipe is formed. Are there any manufacturers in the market that produce internally sprayed lining pipes? If not yet, then this could be a development direction for future lining pipes. This is an advantage for large-diameter pipes that require lining. Suitable for lining pipes with larger diameters, that are not under pressure and handle media of low hazard level.
Isn’t that how internal spray-coated lining pipes are made? Where is the future direction?

The internal spraying equipment I had seen before was only used for straight pipe sections; in factories, sections of internal spraying pipes about ten meters long were prefabricated. What’s on my mind now is: having a machine that can go in and handle long sections of pipes, several hundred meters long and with multiple bends, that have already been installed.
I have yet to see a machine that can penetrate long, winding pipes to carry out spraying operations.
For modern ceramic-lined pipes, the lining is applied after welding
May I ask: Is a \"long pipe several hundred meters long with multiple bends\" manufactured in a factory or on-site?
After it’s installed on site. I want a device that can be used to apply an internal spray coating lining to it.
Fantasy. It can be done on-site; have you considered the costs?
