A complete guide about Flanges and its processes

Flanges covers some types of carbon and low-alloy steel forged or ring-rolled flanges, forged fittings, and valves customize temporarily for low-temperature service and needed notch toughness testing. They are made to specific dimensions or dimensional standards, like the ASME and API specifications. The product furnished to this specification shall assert to the needs of specification A350 lf2 flanges.





Any shall make the steel of the following basic processes: Open-hearth, primary-oxygen, electric-furnace, or vacuum-based melting (VIM). The steel shall be entirely changed, fine-grain practice. The molten steel may be vacuum acted before or during cutting of the ingot. Material for forgings shall persist of ingots or forged, rolled, or strand cast blooms, billets, slabs, or bars.


Heat process


After hot working and before reheating for the heat process, the forging shall be permitted to cool substantially under the transformation scale. Forgings of grades other than Grade LF787 shall be furnished in the normalized, normalized and tempered, or quenched and tempered situation.


While putting all these characteristics and standards, these flanges come across many tests and inspections.




  • Radiography test
  • Flaring test
  • Flattening test
  • Third-party test
  • Visual analysis
  • Macro and micro-test



The ASTM A350 lf2 forged flange are more robust because they are forged from one piece of metal and could be utilized in applications where strength is needed. These flanges could also be welded with the piping process easily. For applications that need toughness and hardenability, the ASME sa 3150 lf2 flanges can be utilized. There are conditions at which ended carbon products are preferred. For that, supply of the A403 WP304killed carbon steel flanges to meet the needs. There are different dimensions and scales involved also. Please don't bother to contact us to a good company if you are looking for high quality product at reasonable rates. You can go online, compare prices and choose a best one.


When hydrogen sulfide gas reacts with water in sour benefit wells, the hydrogen particle is stored on the channels or fittings. The hydrogen stores make the fittings or pipelines to split. Since the 22 WPHY 52 is suitable for hydrogen-induced breaking, they are essential in acrid benefit. These fittings are warmly acted while their manufacturing is going on. The heat treatment may be done concurring to any WPHY 60 fittings details by extinguishing, hardening, normalizing, or stretch relieving. Industries use the elbow WPHY 52 fittings in their process. For case, these fittings are used in or as marine or seawater equipment, off-shore oil boring projects, petrochemicals, gas preparations, warm exchangers, pharmaceutical hardware, mainly chemicals, chemical gear, power generation, condensers, pulp, and paper industries. Fittings made from WPHY 52 material are popular to have a long work life, reliable, durable, and rugged. 

All these process and inspections are done under experts' supervision and as per the industrial set up terms and conditions. Finally, these ASTM A694 F60 flanges are ready in the superior quality of packaging material, protecting it from rust and damages.
