Introducing products with pressure resistance, strength, and heat resistance! They can be used for pressure piping.
At Yoshinen, we handle "20K threaded joints / external coated 20K threaded joints." Due to the revision of the Fire Service Act in May 1990, it has become mandatory to use pipes of Schedule 40 or higher from JIS G 3454 (STPG) when the design pressure of the piping for connected water supply systems exceeds 0.98 MPa (10 kgf/cm²). Our products have performance equivalent to or greater than Schedule 40 pipes and can be used for these pressure piping applications. 【Features】 ■ Certified by the Japan Fire Safety Center ■ Performance equivalent to or greater than Schedule 40 pipes (pressure resistance, strength, heat resistance) *For more details, please refer to the PDF materials or feel free to contact us.
