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.
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.
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.
Heat resistance, chemical resistance, flame retardancy, non-stick properties, compatible resin parts.
This is a part that is finished through special processing from round bar material to a single integrated component.
Nominal diameter 25A to 300A PTFE bellows
The "expansion joint" is made from modified PTFE (T-62), which has high corrosion resistance and does not deteriorate. It is also extremely flexible and boasts high reliability. Additionally, it has reduced elasticity to protect pressure-sensitive glass, graphite, and FRP equipment, improving cost efficiency. The bellows of the "R710 series" use PTFE. The flange is made of SCS13 (equivalent to SUS304), and the reinforcing ring is made of NITRONIC50. For more details, please contact us or refer to the catalog.

We would like to introduce the "Bellows" that our company handles.
We offer a variety of "bellows." The shapes available are "annular type (single peak shape)" and "spiral type (helical shape)." Our lineup includes products with various features, starting with the "super annular," which has uniform wall thickness without any unevenness, as well as "excellent tube" and "soft tube." 【Annular Type (Single Peak Shape)】 ■ Super Annular ■ Super Bellow ■ Tough Omega Bellows ■ Tough Omega Tube ■ Omega 2-Layer Bellows *For more details, please refer to the PDF document or feel free to contact us.
Easy to install and remove, highly durable, and safe to get wet.
◆ The structure is simple, making installation and removal easy. ◆ Maintenance is extremely simple. There are no sliding parts, so there is no need for lubrication. ◆ It can be used for a long time. There is little deformation of the rubber during expansion and contraction, which enhances durability. ◆ The output can be changed. By changing the internal pressure, it can be adjusted over a wide range. ◆ The installation height can be reduced. Compared to other cylinders, it is possible to lower the installation height.
