Daiko Tokyo Branch Processing Case No. 31 Gasket and Industrial Products!

Daiko Tokyo Branch Processing Case No. 31 Gasket and Industrial Products!

Introducing examples of processing gaskets, packing, and industrial products! We process them using various machines, including water jets (high-pressure processing machines)!

Our company has been processing and selling gaskets, packing, and industrial products for over 45 years. We use a variety of processing machines, including one of Japan's largest water jets (high-pressure cutting machines), plotters, and presses, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. We have processed D4000. By incorporating SUS316 as a core material into expanded graphite, we create gaskets with excellent mechanical strength. Since SUS plates cannot be processed cleanly with a water jet, we use a plotter for this processing. Gaskets for water level gauges can be processed in various materials, including T1120, Teflon, and V7020, in addition to D4000.

Gasket Packing Q&A No. 15 High-Temperature High-Pressure Line

Gasket Packing Q&A No. 15 High-Temperature High-Pressure Line

Is there a gasket that can be used for high temperature and high pressure lines?

We would like to introduce a gasket that can be used for high temperature and high pressure lines. The spiral type gasket is a high-performance semi-metallic gasket designed for high temperature and high pressure applications. ■ Structure - It consists of alternating layers of a V-shaped metallic thin strip (hoop) and cushioning material (filler) wound in a spiral shape, with the start and end of the winding fixed by spot welding. - There are four types of shapes: basic form, with inner ring, with outer ring, and with both inner and outer rings, tailored to fit the gasket seat of the target flange. ■ Features - Due to its distinctive structure, it can be used at high temperatures and pressures similar to metal gaskets. - It has excellent sealing properties. - It maintains sealing performance even under severe conditions of thermal cycling from low to high temperatures. * DaiKo's product [D1000 Thin Spiral Gasket Graphite (Graphitic Material)] This is a product from our original brand. We also handle products from domestic manufacturers.

We utilize various processing machines, including one of Japan's largest water jet cutters (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. We processed a white EPDM material with dimensions of 5t and 1320φ x 1160φ. Since the diameter is larger than the width of the raw material, we performed split processing and finished it as a single piece through adhesive processing. We are bending the adhesive joints to check the strength. White EPDM can also be used in food lines.

What is a vortex gasket (spiral-shaped gasket)?

What is a vortex gasket (spiral-shaped gasket)?

We will also explain the correct selection methods for structure, features, materials, and shapes (presence or absence of inner and outer rings)!

The vortex gasket is an essential sealing component for the joints of piping flanges used under harsh conditions such as high temperature and high pressure, due to its excellent sealing performance and durability. The vortex gasket (spiral gasket) is made by alternately winding a thin metal strip (hoop) with a V-shaped cross-section and a soft non-metallic material (filler) that has cushioning and sealing properties. Regarding its structure and features, the metal hoop serves as the framework, providing strength and resilience to the gasket. The filler material fills the gaps, demonstrating high sealing performance. *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.*
