Aesteiron are experts for manufacturing astm a105 flange.We have lots of experience to work in the fields of producing A105 Flanges.  We are well established astm a105 flange manufacturer &a105 carbon steel flanges manufacturers, our manufacturing section is well equipped with leading machines and equipment’s, and we use update the way of manufacturing in order to get desired dimensions and properties of our products. 

sorf flanges a105 is manufactured by most of the steel industries. In sorf flange welding, the fitting or the pipe is set back from the flange. The inner diameter of SORF flange is bit larger than the outer diameter over the pipe. It is the commonly used carbon steel material grade that used to manufacture forge piping components

carbon steel a105 flanges covers seamless forged carbon steel piping components for use in pressure systems at high-temperature service and ambient.Heat treatment is not a compulsory for asmesa 105 flange material except for above Class 300, flanges of special design where the design pressure or design temperature are not known and for items over 4” NPS and above Class 300.

a105 blind flange is forged between 1,700°F to and 2,200°F, followed by quenching and tempering.

a105 weld neck flange forged parts allowed to cool to below 1,000°F before reheating to between 1,550°F and 1,700°F. Slow furnace cooling follows.

a105 lap joint flange slide directly over the pipe and are most commonly used with stub end fittings. A pipe is usually welded to the Lap Joint flange and it is free to rotate around the stub end. It is frequently used for applications that needs frequent dismantling.

a105 galvanized flange are submerged in molten zinc at a temperature of 850F. While this process molten zinc reacts with the steel to form thin layers of zinc alloys. These layers form a barrier that provides exceptional corrosion protection compared to more traditional methods. This assists to increase the productivity and life of each flange.

What is a105 flange?

ASTM A105 is the most generally utilized carbon steel material grade that used to manufacture forge piping components, for example, flange and forged fittings of small diameter piping. This carbon steel material grade is utilized for ambient and higher-temperature administration in pressure frameworks.

ASTM A105 Flange Heat Treatment

Heat treatment is not required except for flanges above Class 300, flanges of special design where the design pressure or design temperature are not known, and for items over 4" NPS and above Class 300. When heat treatment is required, annealing, normalizing, Normalize and temper, normalize and quench and tempering shall be the applied methods.
