About piping construction of Lokring fittings in a fluid outflow state.
When repairing aging pipes, it is common to close the upstream valve. However, have you ever experienced a situation where the valve had a seat leak just at that time? Especially in the case of welding, if there is a fluid leak, construction cannot proceed. The 'Lokring joint,' which can be installed easily and quickly without using fire, solves that problem. I believe you will find it easier to understand by watching the video at the (related link). Since Lokring joints have a proven track record in major domestic oil refineries, chemical plants, and power plants since 2012, you can adopt them with confidence. If you would like to know more specific details, please feel free to contact our representative.

A document summarizing the screw manufacturing technology of Daiichi Industry (forging, cutting, welding) is now available!
Do you know how the screws around you are made? There are various methods for processing screws, including cutting processes that remove metal, plastic processes that shape metal by compressing it, and welding processes that melt and join metals together. Each method has its own advantages and disadvantages, as well as different shapes and materials it excels at processing. Our company possesses the manufacturing know-how necessary for screw production, including "forging," "cutting," and "welding." We also offer "composite processing" that combines these methods. By leveraging the characteristics of each process, we achieve optimal cost and quality in screw manufacturing. As a specialized group in fastening components, our company, which handles "forging," "cutting," and "welding," has published materials summarizing each of these technical details. For more information, please download and view the catalog page below.
