Introducing products compatible with carbon steel seamless pipes conforming to ASTM A106/A53S/A333!
We would like to introduce the "carbon steel pipe fittings" that we handle. The certified pipes are made of carbon steel that complies with standards such as JIS STPG370/STS370/STPT370, as well as carbon steel seamless and ERW carbon steel. Additionally, for schedule 80 compatible pipes, the products comply with ANSI B31.3 (at ambient temperature). 【Certified Compatible Pipes】 ■ Carbon Steel (compliant with JIS STPG370/STS370/STPT370, etc.) ■ Carbon Steel Seamless (compliant with ASTM A106/A53S/A333) ■ ERW Carbon Steel (compliant with ASTM A53E/A587) *For more details, please refer to the PDF materials or feel free to contact us.

Company information
We handle the 'LOKRING' fittings, which provide easy and reliable pipe connections with a level of reliability equivalent to welding. The 'LOKRING' fittings were developed by NASA in 1987 and are used worldwide as a mechanical joint that serves as a non-welding alternative compliant with ASME B31. Because they can be installed easily and quickly without the use of flames, they not only enhance safety but also significantly reduce total construction costs through shortened installation times and lower labor costs. Since 2012, they have been used in many petrochemical plants, thermal and nuclear power plants in Japan, making them a reliable choice.
