TK-783 has been using for over 17 years and each year have to cleaned with Hi-pressure jet for corrosion inspection
Which found that more rust and accumulate inside. Some of which may lead to blockage in the system,
Such as spray nozzle,fouling in system
The corrosive condition of use for long time we have a plan to replace it.
hence, the changing material is SUS304. which can reduce such problems and it doesn't cost for cleaning about
20000 baht/year (Simple cleaning/No need Hi-pressure jet). Which cost return about 6 years by comparing the costs of
different materials around 120,000 baht (Comparing material cost Steel and SUS304)
