Carbon Steel A105 Forged Flanges

Whenever the plates need to be heat treated. We at Ratna Exports have been in business for a long time manufacturing ASTM A105 Flanges. Our company has extensive experience in the field of producing A105 Flanges. In addition to being well-established as ASTM A105 flange manufacturers, we are also well-equipped with the latest machinery and equipment to manufacture our flanges to get the desired dimensions and properties for our products, which is why we use our manufacturing section to produce our products. 

A105 SORF Flanges are set back from the fitting or pipe in the process of SORF flange welding. The inner diameter of the SORF flange is slightly larger than the outer diameter of the pipe. The grade is the most commonly used carbon steel material for forging pipe components.

Several carbon steel A105 flanges are suitable for use in pressure systems at high and ambient temperatures. High-temperature applications require formed carbon steel pipes. Unless the material is above Class 300, if the design pressure or temperature is unknown, or if the material is over 4 inch NPS and above Class 300, heat treatment is not mandatory for ASME SA 105 flange materials.

A105 blind flanges are forged between 1,700°F and 2,200°F, followed by quenching and tempering.

It is recommended that the A105 weld neck flange forged parts be allowed to cool to below 1,000°F before being reheated to somewhere between 1,550°F and 1,700°F, followed by slow furnace cooling.

It is frequently used for applications where the pipe needs to be rotated around the stub end. It is frequently required for dismantling past installations, such as with pipe lap joint flanges, which are usually welded directly to the pipe. Thus, the stub end moves freely around the pipe.

A105 galvanized flanges are submerged in molten zinc at 850F while they are submerged. This process results in molten zinc reacting with steel to form thin zinc alloy layers, creating a barrier that offers exceptional corrosion protection compared to traditional methods. As a result, each flange is more productive and lasts longer.

There is a requirement that heat treats the ASTM A105N weld neck flanges, but it is not mandatory except for flanges above Class 300. In addition, the a105 pipe flange of unique design (where the design pressure and temperature of carbon steel a105 reducing flange are unknown) must be heat treated.

Furthermore, this applies to items exceeding a 4″ NPS and above class 300.

As part of the forged carbon steel ASTM a105 plate flanges heat treatment processes, processes like annealing, normalizing, normalizing and tempering, normalizing and quenching and tempering shall be employed 

The forged parts of the ASTM a105 150 flange dimensions are limited in weight to 10,000 pounds, as per this specification ASTM a105 150 flange dimensions. Forging of the ASTM A105 flange material alloy occurs at temperatures ranging between 1,700°F and 2,200°F and is then followed by quenching and tempering. For forged steel flange parts of grade a105, carbon steel can cool down to temperatures below 1,000°F before re-creating. Following a cooling down of the ASTM A105 Flange, it is then reheated to a temperature between 1,550°F and 1,700 °F afterward. When the carbon steel a105 blind flange has been reheated, it is then cooled slowly in the furnace after the alloy has been reheated.

A105 slip-on flange carbon steel forgings are generally considered as machinable as any other low alloy steel grade. Except for machining, the specification of the ASTM a105 slip-on flange carbon steel does not cover the cold working of the material. 

Tensile and hardness tests are required for ASTM a105 Blind Flanges to verify their strength and flexibility.
