Black coating on both the inside and outside. It is a thick film nylon-coated joint using a fluid immersion method.
"RD fittings" are high-performance fittings that excel in heat resistance and chemical resistance. Thanks to high-quality nylon coating on both the inner and outer surfaces achieved through a flow immersion method, we simultaneously realize cost reduction and improved heat and chemical resistance. The thick (over 300μm) "pinhole-free" nylon coating suppresses blistering (peeling of the coating) caused by high-temperature water. Please use it for drainage pipes where sulfur corrosion and high-temperature wastewater are concerns. 【Features】 ■ Nylon coating on both inner and outer surfaces ■ Black paint on both inner and outer surfaces *For more details, please download the PDF or feel free to contact us.
