Royal molded bellows

Royal molded bellows

Corrosion-resistant, high-temperature resistant, long-life design molded bellows.

We have standardized formed bellows made of Hastelloy® C22 for various movable parts of vacuum equipment (especially semiconductor manufacturing equipment) and for valve shaft seals. ■ Excellent corrosion resistance - It has superior corrosion resistance compared to other Ni-Cr-Mo alloys. - It prevents stress corrosion cracking even against Cl2 and HBr gases. ■ High-temperature strength - It outperforms the room temperature tensile strength and 0.2% yield strength of SUS316L at 650°C. ■ Long lifespan design possible - A lifespan design of 10^6 cycles is achievable with formed bellows. - The dimensions during use have been further reduced compared to conventional designs, allowing for a more compact design.

Welded bellows

Welded bellows

This is an introduction to welded bellows that allow for the selection of end fittings and provide design flexibility.

The "welded bellows" are metal bellows made by connecting thin metal plates on a precision disc by alternately welding the inner and outer diameters. We offer a lineup of "NS, NA standard welded bellows," which are compact and provide a large amount of expansion, and "compact welded bellows," which have increased stroke per wave by over 30% compared to conventional models, achieving cost-effectiveness. 【Features】 <NS, NA standard welded bellows> ■ Compact with a large amount of expansion ■ Low spring reaction force ■ Long lifespan possible ■ Freedom in design with selectable end fittings ■ Y-type end fittings can be welded by the customer ■ No restrictions on installation direction *For more details, please refer to the PDF document or feel free to contact us.

High-performance molded bellows "LFB/SFB"

High-performance molded bellows "LFB/SFB"

Compact design is possible! High-performance formed bellows that achieve a lifespan comparable to welded bellows.

The "LFB/SFB" is a high-performance molded bellows handled by Irie Koken. The "LFB" is a royal molded bellows that achieves a high lifespan comparable to welded bellows (1 million cycles). It has excellent corrosion resistance and prevents stress corrosion cracking even against Cl2 and HBr gases. It outperforms SUS316L in terms of room temperature tensile strength and 0.2% yield strength at 650°. Additionally, the "SFB" is a super molded bellows that can be designed to be more than 50% more compact than conventional molded bellows. 【Features】 ■ Achieves a high lifespan comparable to welded bellows (1 million cycles) ■ Spring constant is less than 1/2 of conventional molded bellows ■ Can be designed to be more than 50% more compact than conventional molded bellows *For more details, please refer to the PDF materials or feel free to contact us.

Special-shaped bellows

Special-shaped bellows

We propose products that meet various needs, from absorbing installation errors to accommodating expansion and contraction displacements.

At Irie Koken, we handle "Specially Shaped Bellows." We offer a lineup that includes the "Rectangular Bellows Series," which is based on square and rectangular openings, the "Elliptical Bellows Series," which is based on rounded rectangular openings, and the "Custom Shaped Bellows Series," which is manufactured according to customer specifications. We propose products that meet various needs. 【Features】 ■ Rectangular Bellows Series - Designed to absorb installation errors at the connection points between chambers and between chambers and gate valves. - Available in two types: folded bellows and welded bellows. ■ Elliptical Bellows Series - Products that improve displacement performance by rounding the corners, which are difficult to achieve with rectangular bellows. - Available in two types: molded bellows and welded bellows. ■ Custom Shaped Bellows Series - Products manufactured in appropriate opening shapes to fit available space when round, rectangular, or elliptical bellows cannot be accommodated due to equipment or piping design constraints. *For more details, please refer to the PDF document or feel free to contact us.
