A105 Forged Sulfur And Acid Resistant Flanges, HIC SSC Flanges, Low Sulfur And Phosphorus Content Flanges

The butt welding flange is not easy to deform, has good sealing, and is widely used. It is suitable for pipelines with large fluctuations in pressure or temperature or high temperature, high pressure and low temperature pipelines. The advantage is that the price is relatively cheap, and the nominal pressure does not exceed 2.5MPa; it is also used for transportation prices On pipelines with expensive, flammable and explosive media, the nominal pressure is around PN16MPa.

Forged flanges generally have lower carbon content than cast flanges and are not easy to rust. Forgings are streamlined, have a denser structure, and have better mechanical properties than cast flanges;

Improper forging process will also cause large or uneven crystal grains, hardening cracks, and forging costs higher than cast flanges.

Forgings can withstand higher shear and tensile forces than castings.

The advantage of castings is that they can produce more complex shapes and lower costs;

The advantage of forgings is that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in the casting;

From the production process, the difference between cast flange and forged flange is different. For example, centrifugal flange is a kind of cast flange.
