ASTM A182 F11 Flanges and SA182 Gr F11 CL 2 Slip on/ Blind/ WNRF/ RTJ

EIL Approved manufacturer And supplier Of ASME SA182 F11 Cl2 Blind/ Slip On Flanges For Oil And Gas Industry In India

ASTM is an American standard that has different grades for different products. One such product is the ASTM A182 F11 Flanges that perform well in severe conditions as well. It is used in applications where only general corrosion resistance is required. As per ASTM A182 F11 Class 3, RTJ Flange manufacturer In India these flanges have low thermal conductivity and tensile strength that is moderately low. It is used in applications where the cold temperature is observed as well as in a high temperature and high pressure environment. A182 Grade F11 Weld Neck Flanges offer good toughness and hardenability.

ASME SA182 F11 Cl2 Blind Flanges are used to carry corrosive gases and fluids at high temperatures. They offer rigidity, and strong creep strength, along with good impact resistance. SA182 F11 Cl2 Slip On Flange is easy to fabricate and is used as they creep resistant. They are able to handle high temperatures of up to 530 degrees C. These flanges have molybdenum added to them. Molybdenum helps in slowing the coagulation and formation of coarse carbide in applications working at high temperatures.

SA182 GR F11 Socket Weld Flanges are therefore used in applications such as petrochemical plants and power generations. Though molybdenum is a good element however overuse of it may reduce the creep ductility of Gr F11 Plate Flanges. Graphitization and breakdown of iron carbide may take place when the temperature exceeds 500 degrees C. To combat both creep ductility reduction and graphitization chromium is added to SA A182 F11 Alloy Steel CL.2 Forged Pipe Flanges. Moreover added chromium also provides resistance to oxidation.
