basic information
Aluminum is a material that is difficult to shape and also has a high level of difficulty in welding. This is due to the following characteristics: 1. It is prone to oxidation during heating. 2. It has an oxide film on its surface. 3. It has a low melting point. 4. It is easily deformed. 5. It is prone to blowholes. 6. It is likely to experience welding cracks, among other issues. Thanks to the skills and know-how developed over many years, shaping and welding techniques have been established, allowing us to respond to these delicate conditions. Additionally, we have a wealth of experience in solving various problems based on numerous achievements, enabling us to respond flexibly. Please feel free to consult and request with confidence.

Applications/Examples of results
Aluminum alloy butt-welded pipe fittings are used in low-temperature applications, including around tanks on LNG carriers, low-temperature piping in air separation plant cryogenic boxes, and piping for low-temperature heat exchangers. Additionally, taking advantage of their corrosion resistance, they are also used in seawater piping for city gas vaporizers and in piping for chemical plants.
