Introducing the basic substrate design for applying lining (thick film)!
We would like to introduce the design of the substrate suitable for fluororesin lining. This is the basic substrate design when applying lining (thick film). Please also refer to it for coating (thin film). For the "corner sections," it is ideal to finish with a minimum of 4R, and if possible, 10R or more. If the inner radius is small, increasing the film thickness will make it more susceptible to the thermal contraction of the fluororesin. At the "welded sections," it is necessary to weld all joint areas (both inside and outside). Additionally, if attaching pipes or similar, all joint areas on the coating surface must also be welded. Unevenness in welding is not an issue as long as the weld is smooth. Please note that pinholes in the weld are not acceptable. If you consult with us before the design phase, we can provide suitable fluororesin lining. *For more details, please refer to the external link page or feel free to contact us.

basic information
**Notes for When Lining the Entire Product** To line the entire product, it is necessary to have hanging points such as holes or screw holes. By hanging it, areas without the fluororesin lining film will occur. If used directly in a chemical tank, these areas without the film may corrode, or chemicals may permeate from these areas, causing the fluororesin lining to peel off, leading to various troubles. To prevent such issues, it is necessary to fill the metal parts at the hanging points without the film with the same material fluororesin by melting (resin welding). **Please consult us in the following cases:** ■ In the case of fluororesin lining performed by another company ⇒ Resin welding is possible for areas without the film ■ Exposed metal due to scratches or dents caused by carelessness during installation ⇒ Corrections by resin welding are possible (Depending on the condition of the scratches and dents, we may refuse) ■ If removal is not possible ⇒ On-site resin welding is also possible (We may refuse depending on the condition of the lining) *For more details, please refer to the external link page or feel free to contact us.*

Company information
It is possible to apply a fluororesin coating (Teflon coating) on the inside of a pipe with an inner diameter of just 1mm. We may be able to handle processing that other companies have declined. Additionally, we have extensive experience in applying coatings for corrosion prevention on manufacturing equipment. We also have a track record in household goods and food-related equipment.
