流浸工業 List of Products and Services

"Ryūcoat Light" is a coated steel pipe that has a thickness of 1.6t and features PVC resin coating on both the inner and outer surfaces. It is very lightweight, weighing about 1/5 compared to SPG (both ends 10KF), which allows for faster construction speed on site. It uses a uniquely developed PVC resin that offers excellent weather resistance, making it suitable for outdoor use. Additionally, it is highly resistant to corrosion and chemicals, so there are no significant changes in weight or appearance. 【Features】 ■ Lightweight, enabling faster on-site work ■ Excellent airtightness: no leaks occur even at a pressure of 0.3 MPa ■ Chemical resistance: no significant changes in weight or appearance For more details, please contact us or download the catalog.

• Water and sewerage pipe fittings

The steel pipe is coated with PVC powder resin on both the inner and outer surfaces, making it usable underwater. Furthermore, to utilize the inherent properties of PVC resin and to increase the density and strength of the resin, we have independently developed a pretreatment process technology.

"Ryushin Industrial Co., Ltd." conducts various resin coatings on metal surfaces using the "Fluid Immersion Method" and manufactures "Leucoat Steel Pipes." Additionally, they offer the "Mini Coat Method," which leaves no hanging marks. The "Fluid Immersion Method" provides a thick coating compared to other painting methods, resulting in very high rust prevention capabilities. 【Features】 ○ Coating Thickness Fluid Immersion Method: Approximately 200μ to 2mm (varies by resin) Electrostatic Powder Coating: Approximately 90μ to 250μ ○ Equipped with one of the largest coating lines in Japan Can coat pipes up to 5.5m and substrates less than 1cm For more details, please download the catalog or contact us.

The fluidized immersion method was developed in West Germany in the early 1950s and was introduced to our company in the mid-1950s. The general concept involves placing a porous partition at the bottom of a container filled with fluidized immersion powder, injecting pressurized air from below, and using that pressure to uniformly suspend the powder above the partition (this is called the fluidized bed). By immersing a preheated substrate (the workpiece) in this layer, a beautiful coating with a uniform thickness of over 200μ, free of drips and pinholes, is formed.

The Mini Coat method was developed in France in 1975, and the following year, our company introduced exclusive implementation rights in Japan. Mini Coat is a processing method that is commonly referred to as non-holding and non-contact, without any "octopus legs" (suspension points), and is often called non-contact coating. The absence of octopus legs means there are no repair areas, resulting in excellent aesthetics and superior corrosion resistance. However, processing of large components is not possible.

A positive or negative high voltage is applied to the sprayed powder, and the grounded substrate generates a relatively opposite charge, electrically bonding the powder to the substrate. This is then placed in a furnace to melt and form a coating film. Since no solvent is used in the thin film, a beautiful coating film of 50 to 150 μm is formed without pollution. However, because the coating film is thin, it is not suitable for anti-corrosion applications compared to the flow immersion method.

The polyamide coating uniformly applied to the threaded surface absorbs the elastic twisting of the bolt caused by various vibrations and impacts. Additionally, the coating, which is elastically deformed when tightened, generates a strong rotational wear resistance force between the bolt threads, preventing the nut from loosening.
