"FF Datchakun" is a fitting that allows for quick attachment and detachment while having valve functionality. Moreover, it enables full flow without constriction inside, allowing for greater flow rates compared to typical quick joints. Traditionally, larger pumps were used with the assumption that flow would be restricted, but by using Ihara's "FF Datchakun," it is possible to flow without pressure loss, allowing for a reduction in pump size. This results in significant energy savings. Additionally, the foolproof feature ensures that detachment cannot occur when the handle is in the "open" position, eliminating concerns about incorrect operation. *Catalog downloads are available.

Ihara's large-diameter bellows valve "PYB" can be delivered in one-third the lead time (compared to our previous products) and is a large-diameter bellows valve. Have you ever felt that large-diameter bellows valves have long delivery times? [In the case of conventional products] 1. Manufacturing of castings 2. Internal surface treatment, polishing, and repairs 3. Cleaning and polishing After repeatedly performing these steps, the products were shipped, and customers had to spend a lot of time purging them after delivery. Manufacturing castings takes time, and in addition, castings can develop cavities, which require significant time for surface treatment to remove. We thought that these issues might stem from the use of castings. Is it possible to create a large-diameter bellows valve without using castings...? From that idea, "PYB" was born. Delivered in one-third the lead time of castings (compared to our previous products) → By using pipes for the body, we resolved the issues associated with castings and enabled quick delivery by internalizing the process from material to completion. Additionally, since the internal surface is clean, there is no need to spend a lot of time purging after delivery.

Piping is intended for the flow of fluids, but the presence of resistance in the flow path can cause various troubles such as temperature rise due to friction, noise from vibrations, and energy loss due to pressure drop. Therefore, Ihara believes that it is better for the flow path of fluids to have less resistance and is always thinking about how to reduce fluid resistance. This document introduces three points on how to reduce fluid resistance. 【Contents (excerpt)】 ■ Threaded joints → Ihara's pipe-insert joint "e-fit" Achieving large flow rates by eliminating steps in the piping and increasing the inner diameter ■ L-shaped joints → Ihara's bent piping Achieving low pressure loss through a smooth flow path ■ Connection of T-shaped joints → Ihara's branching joint Achieving low pressure loss by eliminating steps with joints and reducing labor during installation *For more details, please download the PDF document or feel free to contact us.

Piping, like humans, dislikes stress. When stress is applied to piping, it later manifests as phenomena such as cracking or corrosion. Therefore, we are considering methods to minimize the stress on piping as much as possible. In this document, we introduce one example, the "SLB Method" (Stress Less Bending - a method of bending pipes to prevent residual stress). What are the benefits of bending with the SLB Method? How does the SLB Method differ from conventional bending processes? We provide a detailed introduction along with case studies. *For more details, please download the PDF document or feel free to contact us. You can also view more information in the video below!

We consider all piping components as "fittings." When viewed this way, valves can be thought of as "fittings" with functions such as opening, closing, and adjusting. Therefore, the valves made by Ihara are different from those of "specialized manufacturers." By not being bound by conventional wisdom and thinking from a zero base, we believe we can create products that are unique. We constantly consider what we want to achieve, what challenges we face, and how we can be of service to our customers, based on the type of fluid and application. Through this approach, our company offers a variety of valves with different connections tailored to our customers' needs. *For more details, please download the catalog or feel free to contact us.*

In piping construction, on-site adjustments (known as "gen-gou") are inevitable. Even if the piping is manufactured according to the drawings, during installation, there may be instances where: - Dimensions are insufficient - Positions do not align - Adjustments are needed for installation, which can necessitate on-site adjustments. However, with Ihara's prefabricated piping method called "Pittari-kun," it is possible to eliminate on-site adjustments. This can significantly reduce the time and costs associated with piping construction. Ihara's unique technology, "Pittari-kun!" can eliminate on-site adjustments. ↓↓ For more details, please watch the "related videos" at the URL below ↓↓

A pipe leak has occurred! I want to replace the pipe immediately! "Hey! Please do it right away!" In such cases, you would typically rely on specialized contractors or skilled workers for the piping. If the piping contractor or skilled worker can respond quickly, there is no problem, but have you ever struggled with this urgent response? Our company offers a fitting that responds to "Hey! Right away!" called the "Oi-sugu Flange." It is commonly accepted that "flanges are welded," but the Oi-sugu Flange is a flange that can be connected without welding. Since it is weld-free, it does not require fire, and it is characterized by being "easy and reliable for anyone to install." Benefits: - No need for treatments like acid washing - Easy maintenance due to no fire hazard measures required - No variation in quality - No harmful substances like welding fumes are generated Additionally, to better respond to the on-site "Hey! Right away!" we introduce an evolved "tightening device." What if piping assembly could be done without special skills? Our company offers a wide range of fittings that anyone can easily and reliably install. *For more details, please refer to the PDF catalog.*

Due to the popularity of the "Oi-sugu Flange," we are introducing an evolved "tightening device" to better respond to the needs of the field, 【Oi! Sugu!】. Thank you for the many inquiries and requests for demonstrations. The most common feedback we received was, "I would like the tightening device to be more compact." "It would be great if it could be used with tools available on-site, like impact wrenches, rather than a dedicated device." We have quickly responded to our customers' voices and evolved the tightening device.
