We are one of the pioneer distributors and dealer of ASTM A105, LF2, LF3 and LF6 CARBON STEEL FORGED FLANGES, where a low inter – pass temperature should be maintained. In general, preparation for welding should be similar to ASTM A105 Carbon Steel Forged Pipe Flanges and should include proper cleaning and handling. Joint designs should allow easy access to the weld because of poor weld pool fluidity in ASTM A105 Carbon Steel Forged Threaded Flanges, where designs should also limit total weld volume to reduce shrinkage problems. ASTM A105 Carbon Steel Forged Socket Weld Flanges can be successfully welded using most standard arc welding processes, where pre – heating and post-heating are not required and should be avoided. 

When a filler ASME SA 105 Forged Flanges is needed, a matching composition rod will provide the best match in thermal expansion properties. If a matching composition is not available a high nickel filler metal can be used, where these ASME SA 105 FORGED PIPE FLANGES will result in a weld with different thermal expansion properties. ASME SA 105 Forged Threaded Flanges resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. ASME SA 105 Forged Socket Weld Flanges has excellent resistance to inter – granular corrosion in the as-welded condition. ASTM A105 CS FORGED FLANGES is often utilized in process streams containing chlorides or halides. The addition of molybdenum in ASME SA 105 CS Forged Pipe Flanges improves general corrosion and chloride pitting resistance.
