We shed light on the question of "What is optimal?" for such piping, and what we came up with is "Cool piping with 3E-fit." What is "Cool piping with 3E-fit"? 3E-fit... - Ecology: It must be environmentally friendly Energy-saving, resource-saving, recycling, and no environmental pollution. - Economy: It must have high cost performance Including production costs, usage costs, and disposal costs. - Easy: It must be easy and reliable to install Minimal on-site work and minimal adjustments. Moreover, it should be safe and secure. Cool... Piping is "art." Being beautiful means being "simple," having no "waste," and being functionally superior.
