Carbon Steel Flanges

What Is Carbon Steel Flanges?

Carbon Steel Flanges are made up of a high carbon concentration, giving them enhanced strength and performance. Some alloys are also added within these flanges to diversify their properties. These flanges can combine a range of piping equipment securely. The flanges within this grade can be availed in low, medium, high, and ultra-high carbon concentrations. Higher the carbon concentration better the strength and corrosion resistance. The versatile features make carbon the most utilized material within the piping industry.

Difference Between ASTM A105 Blind Flange And ASTM A350 Lf2 Flanges

ASTM A105 Blind Flange and ASTM 350 Lf2 Flanges are versatile components of the carbon grade. These flanges can be differentiated based on some basic characteristics. An Lf2 flange is generally welded and possesses good impact resistance. Blind flanges don’t possess a face and are bolted directly to the piping components. They are employed to terminate the flow of high-pressure fluids and gases within the system.

ASME SA105 Slip On Flange Oil And Gas Application

ASME SA105 Slip On Flanges is amongst the most common flanges used within this grade. These cost-effective flanges are a preferred choice in low-pressure systems in different oil and gas systems. Their easy installation further testifies to why they are preferred across this industry. Slip on flanges are generally utilized for process lines for the oil and gas industry. Apart from this, they can also be seen in firefighting systems and cooling water lines in onshore or offshore refining or production systems.

Cs Weld Neck Flange Features

Some of the features of weld neck flanges include

  • Superior strength and performance
  • Excellent corrosion resistance
  • Long tapered hub or face
  • Provides excellent stability to piping components
  • Resistance to high pressures and temperatures
  • A superb choice for critical applications
  • A Flange of choice in storing and in the transportation of volatile fluids and gases

ASTM A694 F65 Lap Joint Flange Characteristics

ASTM A694 F65 Lap Joint Flange is a versatile component. Some of the characteristics of this flange include.

  • Made up of a flat face that is used alongside a stub end
  • Excellent resistance to stress during transmission services
  • Superior fatigue and impact resistance
  • The flange can easily swivel around the stub end and the pipe
  • Cost-effective and time-saving.

ASME SA694 F60 Socket Weld Flange Vs ASTM A694 F52 Raised Face Flange

Flanges are versatile components that can be characterized by their strengths, face type, corrosion resistance, and so on.

  • ASME SA694 F60 Socket Weld Flange can be designed with a raised or flat face. An ASTM A694 F52 raised-faced flange is characterized by a raised face, which helps in fixing it to the module effectively.
  • F60 socket weld flanges have a tensile and yield strength of 515Mpa and 415Mpa respectively. F52 raised face flanges to exhibit a tensile and yield strength of 455Mpa and 360Mpa respectively.
  • F60 socket weld flanges possess superior corrosion resistance and strengths in comparison to F52 raised faced flanges
