Rubber bellows for vacuum devices designed for easy attachment and detachment.
This is a rubber bellows for vacuum devices. Normally, metal bellows are used, but in order to improve the costs associated with the bellows itself as well as the "installation and removal labor time and personnel," we have manufactured this rubber bellows for evaluation testing. The thickness is 3 to 4 mm. The size is an outer diameter of 1380 mm and an inner diameter of 1280 mm, with a maximum height of 155 mm when fully extended. Both flange surfaces have holes for bolt fastening, and the installation to the vacuum device is secured by clamping with a metallic flange and bolts. After conducting usage conditions and durability tests, we found that it meets the required functions and also clears the set durability conditions. As a result, the downtime for equipment due to bellows replacement has been significantly reduced, and the number of personnel involved in the work has also been decreased.
Will temperature win, or will technology win? It has heat resistance, is very soft, and has great elasticity.
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.
A four-layer bellows that combines high pressure resistance with a low spring constant, maintaining strength while offering exceptional softness!
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.
