Faqs:
  • What is a flange and how is it used in piping systems?
    A flange, also called a flange plate, is a component that connects pipes together, attached to the pipe end. It forms a detachable connection using a flange, gasket, and bolt assembly to create a sealed structure, used in both pipeline devices and equipment import/export points.
  • What materials are available for these flanges?
    Flanges are available in various materials including WCB (carbon steel), LCB (low temperature carbon steel), LC3 (3.5% nickel steel), multiple chrome molybdenum steel grades, various stainless steels (304, 304L, 316, 316L, 347), and specialized alloys like Monel and Hastelloy nickel alloys.
  • What quality certifications and testing does TOBO provide for their flanges?
    TOBO flanges come with certifications from API, ISO, SGS, BV, CE, PED, KOC, CCRC, PDO, and CH2M HILL. Testing includes chemical analysis, mechanical properties, metallurgical analysis, impact testing, hardness testing, ferrite testing, intergranular corrosion testing, and non-destructive tests like X-ray, PT, UT, HIC, and SSC testing.
  • What are the main advantages of choosing TOBO flanges?
    Key advantages include abundant stock for prompt delivery, reasonable packaging and processes, 15 years of QC team experience with API & ASTM trained engineers, and service to over 150 global customers including major industry players like Petrofac, Fluor, Hyundai Heavy Industry, and Shell.
