Free comprehensive catalog with gasket selection table available!

**Mac Thermo Cover** As introduced in our October newsletter, we are pleased to announce that the catalog for the insulation and heat-retaining jacket, Mac Thermo Cover, is now available. We have received many inquiries about changing from the current metal-type insulation covers. # With the metal type, it is not possible to quickly attach or detach in emergencies. # There are fewer metal contractors available, and we would like to switch to something that can be easily attached and detached. This product addresses those issues. The catalog includes a list of materials used and photos of our achievements, so please take a look! You can download the catalog from the link below. https://www.ipros.jp/news/detail/69834?hub=18+0+0

Q: What is a cam profile gasket? A: It is a semi-metal gasket that has a serrated shape processed on the surface of the gasket core along the circumference, combined with a soft sealing layer on the surface. Q: What are the characteristics of a cam profile gasket? A: Because the surface of the gasket core is processed on the serrated teeth, it provides excellent sealing performance with a line seal along the circumference. Q: Where is it used? A: It is mainly used as a gasket for equipment such as heat exchangers and reactors. Q: What advantages does it have compared to other gaskets? A: In the case of large diameter spiral gaskets, they may come apart during transport or installation, but there is no worry of coming apart with cam profile gaskets! Q: What is the delivery time? A: It depends on the stocked metal materials, width, and dimensions, but we can respond within a few days. Q: What is the maximum diameter that can be produced? A: It is possible to manufacture up to 4000Φ. Q: Can it be used with corrosive fluids? A: Yes, it can. In that case, we will select a suitable material based on the specifications (temperature, pressure, fluid), etc.

"Is it okay to apply paste to expanded graphite?" To get straight to the point, the answer is "In principle, it is better not to apply it." The reason people on site use paste is that it makes leaks less likely, but since it has been applied in the past, I think there is a sense of discomfort with not applying it. Therefore, I would like to explain the reason for "In principle, it is better not to apply it." Most pastes contain oils, and when applied, they soften the gasket and improve its adaptability, thus enhancing sealing performance, but they also reduce the strength of the gasket. Expanded graphite has internal voids, so it absorbs a lot of paste (oil), which significantly decreases its strength. There is a higher risk of breakage when tightened, which is why we respond with "In principle, it is better not to apply it." It is not absolutely forbidden to apply it, but prior confirmation is important. If you have any issues with expanded graphite, please contact Japan Matex.
