EP-fit Series: Dedicated Fittings for Resin Tubes

EP-fit Series: Dedicated Fittings for Resin Tubes

Troubles with resin tube piping... The "EP-fit series" specialized fittings for resin tubes from Ihara can solve the problem.

Dedicated Fitting for Resin Tubes "EP-fit Series" Are you using "double ferrule fittings + inserts" as a matter of course for connecting resin tubes? Using double ferrule type fittings that dig into the resin tube can lead to cutting the tube from over-tightening or leakage issues due to insufficient tightening! To address this, Ihara Science has created a dedicated fitting for resin tubes that is a two-part component and a tightening type. Because it is a two-part component tightening type, it offers the following advantages: - Anyone can easily and reliably perform the work - No need to manage rotation speed, preventing over-tightening and insufficient tightening

Series on Changes in Piping Knowledge: Changes in Welded Piping

Series on Changes in Piping Knowledge: Changes in Welded Piping

Easy to understand with illustrations: Generally used insert welded piping actually comes with its share of troubles. Why not solve it with Ihara's welding-free piping?

Welded piping can be seen in many different sites and devices. It seems to be a common view that welding is the safest and most reliable method for joining components. However, from our perspective as piping professionals, welded piping presents several issues: - Requires a qualified welder - Variability in strength depending on the welder's skill - Cannot be done in areas where open flames are prohibited - Requires welding equipment - Involves many steps for dimension alignment - Long lead times - Requires detachable joints - Acid cleaning is difficult - Handling and repairing issues when they arise is not easy Ihara aims to break the common belief that welding is the best method for joining components and contributes to reducing total costs for customers through the use of embedded joints and bent piping. With Ihara, the number of welded joints can be zero! - Reduction of joints - Shortened construction time (from several days to one day) - Troubleshooting (reduced inspection time, no re-welding) *For more details, please refer to the PDF materials or feel free to contact us.

Garbage-free piping *Materials provided with YouTube video included*

Garbage-free piping *Materials provided with YouTube video included*

Ihara's manufacturing that can contribute to the SDGs.

Ihara is thoroughly committed to reducing waste in both the production process and the usage phase. Since Ihara designs molds for plastic processing in-house and produces materials, it can create joints with minimal cutting chips. As a result, material waste can be reduced by up to 97%, and lead times and costs can be minimized. Additionally, regarding contamination, which is waste during usage, Ihara has developed a joint called "NNT" (an abbreviation for "Smooth Flowing Joint") by using the aforementioned plastic processing technology to clean the inner surface, which was traditionally machined. With NNT, contamination is significantly reduced compared to conventional products, allowing for cleaner fluids within the piping. We will provide detailed explanations in videos about the actual plastic processing simulations and how much contamination is reduced with NNT. ↓↓ For more details, please watch the "Related Videos" at the URL below ↓↓

KTFF solves injury troubles! (Automatic welding joint)

KTFF solves injury troubles! (Automatic welding joint)

Ihara made a joint that is a little innovative with the obvious "certain thing," so that it doesn't hurt your hands and the heater doesn't tear.

When assembling semiconductor manufacturing equipment, we often hear concerns like, "It's dangerous because the gas piping can injure your hands or gloves," and "Wrapping a heater around the gas piping can cause it to tear." Therefore, we at Ihara sought to solve this problem by asking, "What causes hand injuries?" As a result, we developed the automatic welding joint KTFF, which does not injure hands. By changing the manufacturing process, we were able to reduce issues such as injuries to hands and gloves and tearing of heaters.

The embedded joint is a joint of the SDGs.

The embedded joint is a joint of the SDGs.

The embedded joint is not a joint for high pressure. The embedded joint is a joint for SDGs.

Are you familiar with the embedded joint? The embedded joint is not for high pressure; it is an SDGs joint. However, in the public perception, the embedded joint is recognized as a high-pressure joint, with a high price and difficult handling. In reality, it can be used at low pressure, offers high cost performance, and allows for easy and safe connections. Therefore, it is undoubtedly a joint that can contribute to your company's SDGs activities.

What Ihara considers to be "SDGs" plumbing system components.

What Ihara considers to be "SDGs" plumbing system components.

Just by re-evaluating piping materials, you can contribute to the SDGs! Approximately 30% cost reduction as well...

The SDGs are gaining attention in society, but many people may not have a clear image of how to actually implement them. In fact, by slightly re-evaluating piping, we can contribute directly and indirectly to the "SDGs." Direct contributions include reducing power consumption: (1) A piping system with low fluid resistance (2) Reduction in labor hours Reducing environmental impact: (1) Steel has a high recycling rate (2) Steel recycling offers flexibility Indirect contributions include material reduction: (1) Reduction, lightweighting, and compacting of piping materials (2) Low environmental impact during manufacturing (3) Reduction of waste and harmful substances during piping installation.
