What is the difference between ISO and ANSI 254 SMO Flanges?
Flanges are modules, which are utilized in joining piping modules of different shapes and sizes. A flange is typically composed of different classes, which helps in utilizing and identifying different features of the products. ISO and ANSI are important standards, which govern the industry.

  • International Organization for Standardization or ISO flanges are high-quality components, which are agreed by different experts internationally. ANSI 254 SMO flanges are modules that are manufactured after agreeing with a group of members in respective organizations.
  • ANSI standards aim to improve the position of the US markets across global markets. ISO standards aim to help and grow the industry by finding proper solutions for mechanical problems and safety issues.

How much pressure can a Class 300 ASTM A182 UNS S31254 flange take?
Flanges are components designed to possess unique pressure classes. A pressure class in a flange can be determined as the maximum allowable pressure a flange can withstand when there is a gradual surge of temperature across the system. Flange pressure is characterized by different standards set by different unions. A Class 300 ASTM A182 UNS S31254 flange is not the least but also not the strongest flange. These 254 SMO Flanges are designed to have optimum pressure resistance up to 570psi in temperatures of 600 degrees F. As there is a gradual increase in the temperature, the pressure tolerance in the flange slowly recedes.

What is 6Mo ring type joint flange?
A 6Mo ring type joint flange is a super austenitic grade of stainless steel that is made up of superior concentrations of molybdenum and nitrogen. A ring-type joint flange is a type of gasket covering for flanges. These gaskets are machined metallic ring components having a deep groove cut in the face. The high integrity sealing components are widely used in raised face flanges, allowing them to withstand high pressures to securely seal the flanges. The 6Mo components possess enhanced resistance against corrosive media and show high tolerance against pitting by acids.
