The igniting device is installed in the cablehead. Ignition powder (9) is installed in the base pipe. If the pressure generator is conveyed on tubing, cablehead is replaced by impinging ignitor and cable igniting is replaced by bar dropping igniting.

It has been applied to four alloys that are used in oil and gas production, i.e., a 13Cr supermartensitic stainless steel (UNS S41425), duplex stainless steel 2507 (S32750) and two nickel-base FDI Creative Services, Inc. - Howco Group - Results from #20Oct 23, 2014 · UNS S41425 :S41426 :S41427 General scope. The proprietory "Super 13 Cr" duplex steels developed by Foroni, Sumitomo and Corus offer enhanced mechanical properties allied to higher corrosion resistance than standard 13 Cr or 420 Mod. grades.

This 13 Cr martensitic stainless steel is used in the hardened and tempered condition. It is used extensively on completion equipment in both bar and tubular form, for structural and pressure containing members, in standard and CO2 environments. pH, chlorides, temperature and H2S can limit its use in other environments. TTA EnterprisesTranslate this pageAISI 4140 low alloy steel containing Chromium and Molybdenum is the most widely used alloy for oil patch applications. Usually supplied in the hardened and tempered condition at 22 HRC max. it also finds favour in many applications requiring higher strength levels up to 150 KSI 0.2% PS.ALLOY SUPER 13CR (S41426) Hardened and Tempered Bar Description. X2CrNiMoV13-5-2 (1.4415) is developed from the standard 13Cr grade and offer enhanced mechanical properties and corrosion resistance. The low carbon improves weldability whilst maintaining the martensitic microstructure.
