ASTM A182 F1 Alloy Steel Flange Slip On for Pharmaceutical Equipment B16.5

ASTM A182 F1 flange is a commonly used chromium molybdenum alloy steel forging under the ASTM A182 standard. This standard provides strict specifications for the material, manufacturing process (forging), chemical composition, mechanical properties, heat treatment, testing (tensile, hardness, impact, etc.), dimensional tolerances, and marking information of flanges.

What are the key characteristics of ASTM A182 F1 Alloy Steel Flange?

Chromium molybdenum low-alloy steel: This is the core advantage of ASTM A182 F1 alloy steel flanges. The addition of chromium and molybdenum elements can significantly improve the strength, resistance to slow plastic deformation, oxidation resistance, and resistance to slight corrosion such as steam oxidation of ASTM A182 F1 alloy flanges at high temperatures.
Good high-temperature strength: Compared to carbon steel such as ASTM A105, ASTM A182 F1 alloy steel can maintain higher strength at temperatures above 300 ° C, making it more suitable for more demanding high-temperature conditions.
Weldability: ASTM A182 F1 alloy steel has moderate weldability. Preheating and post weld heat treatment are required during welding in the temperature range of 150-350 ° C. Stress relief annealing is usually carried out in the temperature range of 620-675 ° C to reduce the hardness and residual stress of the welding heat affected zone, prevent cold cracks, and improve toughness.
Machinability: The hardness control after heat treatment gives ASTM A182 F1 alloy steel relatively good machinability.

A slip-on flange is connected to the pipe or the fittings by two fillet welds, one executed inside and one outside the cavity of the flange.

Slip-on flanges are also defined “Hubbed Flanges” and they are easy to recognize due to their slim and compact shape.

WELD NECK VS SLIP ON FLANGE

Flanged joints made with slip-on flanges are, in the long run, a bit more fragile than connections made with welding neck flanges (in similar service conditions). This seems due to the following facts:

a welding neck flange features a tapered hub, absent in a socket weld flange, which distributes the mechanical stress between the pipe and the flange more evenly
a welding neck joint as only one welding area instead of two (socket weld flange).

Another advantage of the welding neck flange is that it can be connected either to pipes and fittings, whereas socket weld flanges suit pipes only.
