The "4-layer bellows" is a vibration-absorbing bellows used in vibration piping and vacuum vibration dryers, where softness and ultra-long life are required under high pressure. Despite the high operating pressure, there are limitations on the length of the bellows, making it suitable for valves, safety valves, mechanical seals, rotary joints, etc., which have constraints on spring constants. We can meet various requirements with different combinations of plate thickness, number of layers, materials, and more. 【Features】 ■ Vibration-absorbing bellows for vibration piping and vacuum vibration dryers ■ Combines high pressure resistance with low spring constant ■ Maintains strength while providing excellent softness ■ Suitable for valves, safety valves, mechanical seals, etc. ■ Various combinations of plate thickness, number of layers, materials, etc. are possible *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "SUS310S Stainless Steel Bellows" handled by Sangen Rasenkan Kogyo. This bellows is made from stainless steel that has higher high-temperature resistance than SUS316L. Although it has lower heat resistance than Inconel (INC625) material, it is cost-effective and can be used at temperatures up to 700°C. Due to its unique roll forming and the use of thin plates, it is very soft and has great elasticity. 【Features】 ■ Made from "SUS310S" material ■ Higher high-temperature resistance than SUS316L ■ Cost-effective and usable at temperatures up to 700°C ■ Manufactured using unique roll forming and thin plates *For more details, please refer to the PDF document or feel free to contact us.

Introducing the "Multi-layer Bellows" handled by Sangen Rasenkan Kogyo. By stacking thin plates, the plates slide against each other, creating a soft and flexible bellows. They are used in vibration absorption and vacuum vibration dryers where flexibility and long lifespan are required under high pressure, and are also widely used in safety valves, valves, and mechanical seals. 【Features】 ■ Soft and flexible ■ Made by stacking thin plates ■ Remarkable softness even with the same plate thickness as conventional products ■ Used in vibration absorption and vacuum vibration dryers ■ Widely used in safety valves, valves, and mechanical seals *For more details, please refer to the PDF document or feel free to contact us.

Addressing global environmental issues such as air pollution and global warming is an urgent task, and the needs for the development of new functional materials active in the energy and environment sector, as well as for semiconductor equipment, charged particle accelerators, and seals for various control devices, are becoming increasingly sophisticated. To meet these needs, our company is developing and manufacturing bellows made from special materials rich in corrosion resistance and heat resistance, such as titanium, Hastelloy, and Inconel.

• tube

This is a flexible tube that can be bent easily and freely. 【Features】 ● As it is a "single mountain tube," it excels in minimum bending radius and repeated bending radius. ● Since the tube consists of independent sections, the direction of force due to pressure acts only in the axial direction. Therefore, there is no impact on the valley parts of the tube, resulting in outstanding durability.

This is a bellows (accordion, pleated) made from expandable components that utilizes expansion, spring properties, and airtightness to be used as a shaft seal or airtight sealing material. 【Features】 ● The plate thickness is thin, and it can be manufactured from 0.11 to 0.5 mm. ● The diameter can be produced from 9.5 to 850 mm. ● It is soft, highly elastic, has a low spring constant, and has a long lifespan. ● For roll forming, diameters from 32φ to 850φ can be manufactured to your desired dimensions in 1 mm increments, with no mold costs. ● Multi-layer bellows (2-layer, 3-layer, 4-layer structures) can also be produced, allowing for high pressure use with the same expansion amount as single-layer types. ● It can be manufactured from special materials, so we can respond to various requests. ● We also accommodate orders for supplied fittings, small lots, and short delivery times. ● For the production of high-pressure gas equipment that meets the High-Pressure Gas Safety Act testing standards, please leave it to us.
