What is ASTM A182 F51 flange?
ASTM A182 F51 is a specification for duplex stainless steel which offers high resistance to different types of corrosion. The Duplex F51 Flanges is able to withstand general corrosion, crevice corrosion, and pitting. The Uns S31803 Duplex Stainless Steel Blind Flange has high weldability and mechanical strength. This is why the Duplex F51 Weld Neck Flange material is suitable for applications which take place in chloride and hydrogen sulphide containing environments. The Sa 182 F51 Slip On Flanges come with a minimum yield strength of 450 MPa, and minimum tensile strength of 620 MPa. The ASTM A182 F51 Flanges are widely used for various applications in industries like petrochemical, petroleum, and other high performing piping systems.

How to measure f51 flange thickness?
The F51 Flange thickness can be measured with the given formula:
tm = t + c
Where, t= d √(CP/SE + 1.9 WhG / SEd3),
Here, d= diameter,
C= a factor that depends on the head attachment method, shell dimensions, etc.
E= joint efficiency
HG= gasket moment arm
W= total bolt load for a given circular head
P= internal design pressure
S= maximum allowable stress value

How to check MTC and ultrasonic test report of the duplex f51 flanges?
The MTC and hydro test report of Sa182 S31803 Flanges contain the following:
- At the top, you will get information about the manufacturer who manufactured the material.
- The heat number or lot number is specified in the test. All the material properties including chemical properties, mechanical properties, etc., are linked with the heat number. These properties are known as the technical delivery conditions.
- The test report also contains the material specification and grade. While reading the reports, these should be matched with the minimum requirements given in material specification for technical and delivery conditions.
- The MTC should also comply with the delivery conditions, like manufacturing process, type of flange, etc.
- It also has a material dimension.
- The mechanical properties will be present in the MTC for each heat number.
- Additional testing, like ultrasonic test can be performed wherein the flanges are ultrasonically tested. The flanges are also tested for their microstructure.
