Glass flake lining construction example: Chemical duct

Glass flake lining construction example: Chemical duct

Manufacturing ducts with SS400! Introducing a case that received high praise for the coating application.

We would like to introduce a case where we achieved a change in manufacturing materials by adopting a coating for the chemical duct. Materials such as SUS317L, which are long-lasting stainless steel, were damaged within a few weeks, while Hastelloy C could be used continuously but was not cost-effective. To enable cost reduction, we manufactured the duct using SS400 and applied a high corrosion-resistant coating from CoroCoat. [Case Overview] ■ Issues - Long-lasting stainless steel materials like SUS317L were damaged within a few weeks, and while Hastelloy C could be used continuously, it was not cost-effective. ■ Results - The duct is in continuous use and has received high praise for the coating application. *For more detailed information about the case, please refer to the related links. For more details, please check the PDF document or feel free to contact us.

Points for Selecting Plate Thickness in Box Duct Manufacturing

Points for Selecting Plate Thickness in Box Duct Manufacturing

By controlling the selection of board thickness, it is possible to reduce costs as well as shorten delivery times! There are important points such as marketability and ease of acquisition.

In the production of box ducts, it is more efficient to fabricate using only 2.3t instead of 1.6t with angle reinforcement, as this can shorten delivery times and reduce costs. In precision sheet metal processing, the cost of processing decreases as the thickness of the material becomes thinner due to material costs. This trend is particularly strong with high-cost materials such as aluminum and stainless steel. However, despite using the same material, thicker sheets can sometimes be cheaper due to factors like availability and ease of procurement. For example, with SUS304, a commonly used stainless steel, 3.0mm thickness is more readily available and cheaper than using 2.5mm thickness. 【Features】 ■ Cost reduction ■ Improved work efficiency ■ Further shortening of delivery times *For more details, please download the materials or contact us.
