Introducing the three major benefits of solving the challenges of high temperature and high pressure lines!

"In high-temperature and high-pressure steam lines, the heat and pressure resistance of sheet gaskets has reached its limit." "In areas with significant temperature fluctuations (thermal cycles), gaskets quickly degrade and leaks occur." "We need a highly reliable sealing material that can handle everything from cryogenic liquefied gases to ultra-high temperature exhaust gases with a single structure." These are critical sealing challenges that arise in important lines, often referred to as the heart of the plant. In response to these challenges, Nichias Corporation presents the "Vortex Gasket" (spiral-shaped gasket), which combines the advantages of "metal" and "non-metal" to provide solutions. This article will delve into the three significant benefits that this semi-metal gasket brings to the field, how it can solve the difficult sealing challenges you face, and provide specific guidelines for selecting the appropriate product from a wide range of options, all explained from a professional perspective. *For detailed content of the column, please refer to the related link.

Case Study of Processing Steam Gaskets T1120

Case Study of Processing Steam Gaskets T1120

Case Study of Processing Steam Gaskets | Water Jet Processing for Center Holes and Multiple Holes

■Overview of Processing Example Product Name: T1120 Steam Gasket Dimensions: 128 square (Center hole φ76, multiple bolt holes) Material: TOMBO No.1120 Processing Method: Water Jet Cutting The outer shape is square, featuring a large diameter center hole in the middle and multiple mounting bolt holes arranged around it. Since this product is used in steam lines, dimensional accuracy to ensure stable sealing performance and positional accuracy of the center hole and bolt holes are critical requirements. This product uses T1120 material, which emphasizes steam resistance, aiming to maintain stable performance even under steam conditions. Water jet cutting was selected as the processing method. Since T1120 contains fibrous materials, it tends to exhibit variability in edge quality and dimensional accuracy when processed with cutting tools. By using the non-contact method of water jet cutting, it became possible to reproduce the shape, including the center hole and multiple holes, according to the drawings while minimizing the load on the material. As a result, this contributes to stabilizing processing accuracy and improving assembly compatibility.
