MATERIAL

CHEMICAL COMPOSITION

Element C Mn P S Si Copper Ni Cr Mo V
Composition, % 0.35 max 0.60-1.05 0.035 max 0.040 max 0.10-0.35 0.40 max (1) 0.40 max (1) 0.30 max (1-2) 0.12 max (1-2) 0.08 max

(1) The sum of copper, nickel, chromium, molybdenum and vanadium shall not exceed 1.00%.
(2) The sum of chromium and molybdenum shall not exceed 0.32%.
For each reduction of 0.01% below the specified carbon maximum (0.35%), an increase of 0.06% manganese above the specified maximum (1.05%) will be permitted up to a maximum of 1.35%.

FLANGE MANUFACTURING CONSIDERATIONS

Heat treatment is not mandatory requirement except:

  1. Flanges above Class 300
  2. Flanges of special design where the design pressure at the design temperature exceeds the rating of Class 300.
  3. Flanges of special design where the design pressure or design temperature are not known.

ORDERING INFORMATION

There are several things you’ll need to know when purchasing flanges, including diameter, pressure class rating, type of connection, schedule (for weld neck and socket weld), material, face type, and series A or B (only necessary for flanges above 24” NPS). 

QUANTITY

To couple two joints of pipe, two flanges can be used.  For a greater number of joints, the formula will be: # Flanges - 2 X (# Pipe Joints - 1)

CARBON & STAINLESS FLANGES

  • Standard Carbon Steel Flanges (A105): ASTM A105 is an ASTM specification dealing with forged carbon steel piping components
  • Stainless Steel Flanges (A182): This specification covers forged or rolled alloy and stainless steel (304, 304L, 316L) flanges. This spec also covers other alloys including chrome (i.e. A182 F11)
  • High Yield Flanges (A694): ASTM A694 is the standard specification to cover carbon and alloy steel forgings for pipe flanges, fitting, valves and other parts for high-pressure transmission service.  Applications include, but are not limited to, in wellhead and Christmas-tree manifold equipment in oil and gas industry.  The two numbers in each grade indicate the yield strength requirements, in ksi.
  • Low-Temp Flanges (A350): This specification covers several grades of carbon and low alloy steel forged or ring-rolled flanges (LF2 in low-temp applications).

SPECIAL ALLOY FLANGES

  • Alloy 20 (ASTM B464/B729)
  • Duplex 2205 (ASTM B790)
  • Super Duplex 2507 (ASTM B790)
  • Hastelloy C276 (ASTM B619/B622)
  • Incoloy 800 (ASTM B154/B407)
  • Incoloy 825 (ASTM B423/B705)
  • Monel 400 (ASTM B165/B725)
  • Inconel 625 (ASTM B444/B705)
