Coupling "Flexible Hose/Expansion Joint"

Coupling "Flexible Hose/Expansion Joint"

Customize according to the installation conditions and can be manufactured in a short period! Introducing fittings with a structure that has valleys.

We handle "Flexible Hoses/Expansion Joints" at our company. The "Flexible Hose" is made of hard and durable stainless steel, yet it can be bent freely due to its corrugated design. It serves the purpose of connecting equipment of different heights and repairing misalignments in piping. Similarly, the "Expansion Joint," which has a similar corrugated structure, is a product that absorbs thermal expansion of piping caused by high-temperature gases, steam, and fluids. 【Features】 <Flexible Hose> - Unlike straight metal pipes, it has a bellows design. - Used in various places, from large piping in factories to household lifeline piping. <Expansion Joint> - Prevents piping from disconnecting or breaking due to the expansion and contraction of metal caused by heat. - Types that absorb pressure and vibration are also available. *For more details, please refer to the PDF document or feel free to contact us.

Expansion Joint

Expansion Joint

Supports up to 800℃! Prevents pipes from coming loose or breaking due to the expansion and contraction of metal caused by heat.

The "expansion joint" is a product that can absorb the expansion and contraction of piping with a structure that has peaks and valleys, similar to a flexible metal hose. By adding peaks to the pipe, it allows for expansion and contraction, just like a flexible tube. It is a joint that absorbs thermal expansion of piping caused by high-temperature gases, steam, or fluids, preventing the piping from coming apart or being damaged due to the expansion and contraction of the metal caused by heat. We also offer types that absorb pressure and vibration. 【Features】 ■ Structure with peaks and valleys ■ Can absorb the expansion and contraction of piping ■ Not constrained by blades ■ The bellows (tube) part can freely expand and contract ■ Made of stainless steel, capable of withstanding temperatures up to 800°C *For more details, please refer to the PDF materials or feel free to contact us.

[Case Study] Reliable FRP Waterproofing Construction and Reduced Work Time

[Case Study] Reliable FRP Waterproofing Construction and Reduced Work Time

Successfully shortened construction time! Introduced Iwata Drain "F-1" for FRP waterproofing work.

At Iwata Co., Ltd., we proposed the Iwata Drain "F-1" to Mr. S, who is installing FRP waterproofing, as part of our efforts to shorten work time and carry out the work efficiently without any leaks. The bonding surface with the waterproof layer is pre-roughened, eliminating the need for additional processing, and the connection and installation with the pipe are simple. This allows for easy and reliable waterproofing work, resulting in a reduction in construction time. 【Background of Introduction】 - Installation of FRP waterproofing in built-for-sale houses - Handling multiple sites at once - Need for efficient construction - Request: Shortening work time without causing leaks *For more details, please refer to the catalog or feel free to contact us.
