API 5L X46 Kab Pipe piav qhia
API 5L X46 pipeline steel feem ntau yog ua los ntawm cov pa roj carbon steel lossis qis- alloy steel thiab ua tiav los ntawm kev kub dov. Nws cov khoom tseem ceeb muaj xws li:
Lub zog thiab Toughness Balance: X46 qib muaj lub zog tawm los nruab nrab, muaj peev xwm tiv taus lub siab sab hauv los ntawm kev thauj khoom thaum muab kev cuam tshuam zoo, ua rau nws haum rau nruab nrab - mus rau siab - cov kav dej siab.
Weldability: Cov hlau muaj pes tsawg leeg tau ua kom zoo kom txo qis kev tawg thaum lub sij hawm vuam, ua kom yooj yim rau ntawm - qhov chaw sib txuas.
Corrosion Resistance: Anti- muaj peev xwm tiv thaiv corrosion tuaj yeem txhim kho ntxiv los ntawm cov txheej txheem los yog kev tiv thaiv cathodic, txuas ntxiv lub neej kev pab cuam.
API 5L tus qauv qhia meej cov cai rau kev tsim cov X46 steel yeeb nkab fittings, nrog rau cov txheej txheem tseem ceeb suav nrog:
Steelmaking thiab Nruam Casting: Tswj cov ntsiab lus ntawm impurities xws li sulfur thiab phosphorus kom ntseeg tau cov khoom purity.
Txheej txheem txheej txheem: Siv longitudinal seam welding (LSAW), kauv seam vuam (SSAW), los yog seamless (SMLS) cov txheej txheem, nrog rau cov txheej txheem sib txawv tsim nyog rau cov yeeb nkab diameters sib txawv thiab cov kev xav tau siab.
Kev tshuaj xyuas thiab txais: Yuav tsum tau kuaj hydrostatic, kuaj ultrasonic, X-ray tshuaj xyuas, thiab lwm yam, kom paub tseeb tias muaj teeb meem - dawb.
Kev tu thiab kev tswj lub neej
Kev saib xyuas tsis tu ncua yog qhov tseem ceeb los ua kom muaj kev nyab xeeb ntawm cov kav dej:
Txheej tshuaj xyuas: Tshawb xyuas cov tshuaj tiv thaiv -corrosion txheej txhua 3-5 xyoos rau kev puas tsuaj.
Kev ntsuas siab: Siv cov sensors los saib xyuas cov raj xa dej siab hauv lub sijhawm.
Kho qhov tsis xws luag: Siv cov txheej txheem trenchless xws li lub tes tsho txhawb nqa los kho lub zos corrosion lossis deformation thaum kuaj pom.
