VẬT LIỆU HÀN HỢP KIM ỨNG DỤNG TRONG CÔNG NGHIỆP HÓA DẦU

(Xin lỗi, chúng tôi đang trong quá trình chuyển ngữ sang tiếng Việt,... )
In the petrochemical industry, the increased temperature and hydrogen pressure under operating conditions requires new steels and welding consumables to satisfy more rigid specifications: mechanical property requirements following complex heat treatment Cycles.

OERLIKON OE CROMO S225V is a 2 ¼Cr1Mo¼ V solid submerged arc welding wire with controlled very low levels of impurity and residual elements.

OERLIKON OP CROMO F537 is an agglomerated fluoride basic submerged arc welding flux specially designed for welding heat resistant steels. This flux has a very low hydrogen potential and exceptionally low silicon pick up and a neutral behaviour in terms of Manganese.

OERLIKON CROMO E225V is a basic coated 2.25%Cr1%MoV electrode suitable for welding creep resistant steels. Core wire alloyed electrode. The weld metal chemistry is very low in tramp/impurity elements allowing to respect the X factor <12 ppm) and J factor < 120 ppm) and showing excellent resistance to the step cooling test, not susceptible to in-service embrittlement. Crack resistant with excellent tensile strength at high temperature and good creep rupture strength. Very low diffusible hydrogen (HD<4ml/100g). The CROMO E225V offers excellent operability in butt and fillet joint. All position welding (no downhill), the 3.2 and 4 mm diameter electrodes are suitable for positional welding (uphill). Stable arc with excellent bead shape. Suitable for use with either DC positive and with AC.

Solutions for P91 and P92 creep resistance applications

Material developments such as creep advanced 9%Cr resisting steels for high temperature and high pressure components, still play a big role in the new projects in the field of the super-critical and Ultra-supercritical steam parameters applications.
The T/P91 (9%CrMo) materials are now well recognized and in use worldwide. A specific focus have been engaged some years ago to more advanced grades such as T/P92 and this steel has already been welded in some projects in Europe, USA, Japan and China.
Even though these T/P92 materials are used at high temperature, where toughness is not a matter of concern, it is important that the welded joints show also a good toughness at room temperature, for fabrication and construction steps and for start-up and shut down considerations.

CROMOCORD 9M : basic synthetic electrode classified AWS A5.5: E 9018-B91 H4 type 9Cr1MoV-Nb-N for creep resistant steels ASTM T/P 91, forgings and thick-walled cast steel (G-X12CrMoVNb9-1). Nickel free weld metal to improve Rm at high temperature. Suits perfectly the piping works, as well as the casting repairs (steam valves, steam turbine casings).

CROMOCORD 10M: Basic electrode classified A5.5: ~ E 9018-G H4. Welding of ASTM steel plates, pipes and forgings assembly, cast valve casing, cast Steam turbine casing for assemblies and repairs. For base materials such as GX 12 CrMoWVNbN 10 1 1 or similar.

CROMOCORD 91 : Basic synthetic electrode classified A5.5: E 9018-B91 H4. 9Cr1MoV-Nb-N for creep resistant steels T/P 91. (Ni+Mn) restriction to increase the Ac1 temperature in order to avoid harmful microstructure transformation during industrial PWHT.

CROMOCORD 92: Basic synthetic electrode E9018-G H4 9Cr1/2Mo W-Co-V-Nb-N for creep resistant steels T/P 92: X10CrMoWVNb9-2. Very low impurities level, outstanding innovative alloying regime utilising 1%Co (achieving better microstructure after PWHT, improving creep resistance properties).

CROMO E91 : E9015-B91 H4 matching core wire basic coated electrode 9Cr 1Mo VNbN electrode for welding of T/P 91 materials. Weld chemistry very low in tramp/impurity elements. (Ni+Mn) restriction following the most demanding guidelines, for a better Ac1 temperature achievement after industrial PWHT.

CROMO E92: E9015-B92 H4 matching core wire basic coated electrode 9Cr 1/2Mo 1.5W VNbN electrode for welding of T/P 92 materials. Fine tuning of the chemistry for better Rm at high temperature. Excellent tensile strength in creep regime.

Submerged arc combination OP90W and OE-S1CrMo 91:
Classified AWS A5.23 F9PZ-EB91-B91. Specially designed for high creep resistant alloys such as T/P91 materials. The OE-S1CrMo91 wire offers a very high purity of the weld metal, and the high basicity of the flux provides a maximum resistance to hot cracking at high interpass temperatures. High charpy toughness is combined with good creep properties. Flux from DRYBAG can be used without redrying (300°C-350°C). (Ni+Mn) restriction following the most demanding guidelines, for a better Ac1 temperature achievement after industrial PWHT.
