A pipe thread with strong joint strength! Achieves excellent earthquake resistance, pressure resistance, and durability!

The "Rolling Nipple" is a pipe thread that has strong bonding strength with fittings and excels in earthquake resistance, pressure resistance, and durability. Traditionally, pipe threads used in piping fittings were mainly produced through cutting processes, but this led to various issues in performance due to the reduction of effective pipe thickness and inconsistencies in thread precision and surface smoothness. Our product achieves a high-precision and smooth thread surface through rolling, improving the adhesion between male and female threads. It resolves the issues associated with cutting threads. 【Features】 ■ Earthquake resistance ■ Pressure resistance ■ Durability ■ Sealing performance *For more details, please refer to the catalog or feel free to contact us.

We will provide a clear explanation of the kintone plugin "StockNaut," which allows you to richly describe multiple images embedded in a multi-line text field. The "Markdown syntax" adopted by StockNaut enables the creation of text that is easy for both humans and generative AI to handle. By combining it with generative AI, you can experience the benefits of StockNaut at 120%! We welcome those who are struggling with document creation, including manuals, to join us. 【Recommended for the following people】 - Those who want to create procedures, manuals, or knowledge bases on kintone. - Those who find it cumbersome to adjust formatting every time they create a manual. - Those who have heard of StockNaut but have not yet tried it. - Those who want to structure knowledge and refine writing in anticipation of future AI utilization.

The basic course on agricultural entry for companies is designed for business owners and representatives who are considering entering the agricultural sector. It provides a clear explanation of the structure of the agricultural market, the considerations for entry, and the necessary points to establish a successful business, making it easy to understand for beginners. Agriculture does not succeed simply because the market is growing, nor can it thrive solely with cultivation techniques. It becomes a business only when products are produced and sold. Furthermore, creating a system that maintains this state while generating profits and fostering growth is crucial. In this course, you will systematically learn the thought processes for judging agricultural entry from three perspectives: "market," "failure," and "success." This content is recommended not only for companies considering agricultural entry but also for those in the information-gathering stage.
