From Daniel Luder of Woodside on August 23, 2011:
     Install the pipe into spinning device ( i.e., pneumatic driven) on a predetermined angle, suitable for the coatings viscosity. Pour the coating into the pipe, ensure ambient curing temperature complements the process.

From richard d souza of stoncor middle east llc on August 23, 2011:
     I do not know if there is good way to apply lining material other than flow coat or with the help of rollers. The best way as far I know is using rollers, and,again,  it depends on the length of the pipes and accessibility from both ends.  I have found that using straightened-out, short-nap rollers to be most effective because it allows the product to be rolled around as well as in and out more or less uniformly. Actually, you should apply two medium coats with one light coat to get even thickness. The other method is to use a flow coat application method as suggested by the previous expert and keep the pipes slowly rotated on rollers at a slight inclined position. Using spray equipment on such small dia pipes is beyond me and always end up in having lot of film build defects and puddling of coating at the 5-7 position.

From Lee Edelman on August 22, 2011:
     For CIPP, Cured In place Pipe Lining, you can determine the thickness by lining type and resin selection  (either reinforced or non-reinforced). Before using this system check the maximnu use temperature. There are other application processes that uses 360 degree spray on smaller diameter pipe.  There could be issues with film build and defects if this system is not properly applied.

From Jay Barstow of Aeroflor Coating Services on September 27, 2011:
     I used a high-speed (10,000 RPM) "flying head" on a pneumatic die grinder ... could get below 2" that way.

From Jesse Gonzales of Brock Services on August 22, 2011:
     Use a flow coat application method.
