The advantages of carbon steel forged flanges

Carbon steel forged flanges mean the forging flange material is carbon steel.Carbon steel forged flanges have different hardness and strength during the use and production,which can play a different role and show different characteristics.Flange connection may need to bear very high tensile,compression,torsion,shear strength,carbon steel forged flange is the better choice.The carbon steel forged flanges materials contain ASTM A105,A350 LF2,SS400,P235GH,P250GH,C22.8,Q235,20#,16Mn,etc.

The advantages of carbon steel forged flanges:

High impact: Because the unique impact strength function is significantly improved compared with other solid wall tubes, the ring stiffness is 1.3 times that of the solid wall.

Long service life: the pipe under the rated use temperature and pressure, the service life of more than 50 years, with anti-UV, anti-radiation, so that the product will never fade.

Good corrosion resistance: in addition to a few hydrogenating agents, can withstand a variety of chemical media corrosion, the flange has excellent acid, alkali, corrosion resistance, will not rust, will not erode, will not breed bacteria , no electrochemical erosion.

Good thermal insulation: because the material thermal conductivity is low, the thermal conductivity of 20 degrees Celsius is 0.21-0.24W / mk, much smaller than steel pipe (43-52W / mk), purple steel pipe (333W / mk), so PP-R Good tube insulation

Good heat resistance: when the working water temperature is 70 degrees, the softening temperature is 140 degrees.
