SA 181 Gr 1 Class 60 Blind Flanges and A181 Class 70 Slip On Flange supplier in Mumbai

ASTM A181 Flange Manufacturer

What is ASTM A181 Flange?
ASTM A181 flange is carbon steel grade that is used in general-purpose forged piping equipment. These flanges have a standard chemical composition giving them enhanced resistance and tolerance. The versatile flange type is limited to a maximum weight of 10000 lb. The flange type can be availed in definite shapes and sizes to suit different project requirements.

Difference between ASTM A181 Grade 1 vs Grade 2 FLange
ASTM A181 Grade 1 and Grade 2 flanges are versatile classes of this grade. Both these classes have a similar chemical composition but can be distinguished from certain features. The ASTM A181 grade 2 flange has higher strength and load-bearing capacity than the ASTM A181 grade 2 flange.

ASTM A181 class 60 vs ASTM A181 class 70 Flange
The A181 covers two classes of 60 and 70. Both these classes can be distinguished on certain features. 

  • ASTM A181 Class 60 flange is designed with a minimum tensile strength of 60ksi with a yield strength of a minimum of 30ksi. These flanges can be readily elongated by 22%.
  • ASTM A181 Class 70 flange possesses a minimum tensile strength of 70ksi with a minimum yield strength of 36ksi. The flange type can be elongated by 18%.

ASTM A181 vs ASME SA 181 Gr 1 Flange
ASTM and ASME are two of the most common and oldest standards used to manufacture piping modules in the A181 grade 1. Both of these standards have similarities but can be differentiated based on certain aspects.

  • ASTM A181 gr 1 covers shapes and structural qualities of different piping grades. The grade is designated to cover 12,000 more standards for non-pressurized vessels.
  • ASME SA 181 gr 1 covers design codes for manufacturing different pressure-rated applications. ASME grade covers nearly 600 codes for fabricated pressure vessel grades.
