Material Performance & Manufacturing Control ntawm Huayang

API 5L LSAW kav dej rau kev pabcuam roj feem ntau yog tsim nyob rau hauv qib ntawm X52 txog X70, nrog rau X60 thiab X65 feem ntau teev rau cov kav dej. Yam tsawg kawg nkaus yield zog li ntawm 290 MPa rau Qib B mus txog 485 MPa rau X70. Raws li PSL2, cov kev txwv nruj dua yog siv rau cov pa roj carbon sib npaug, sulfur, phosphorus, thiab cuam tshuam rau lub zog, ua kom muaj kev txhim kho weldability thiab tawg tsis kam. Huayang Steel Pipe siv cov ntawv hlau tsim nyog nrog kev tswj dov thiab nplua -grain microstructure. Kev tsim ua tiav los ntawm JCOE lossis UOE cov txheej txheem, ua raws li ob npaug -sab submerged arc vuam. Txhua cov yeeb nkab yog raug rau 100 feem pua ntawm kev soj ntsuam ultrasonic, kuaj hluav taws xob thaum xav tau, kuaj hydrostatic, thiab tag nrho cov cuab yeej pov thawj kom ntseeg tau tias ua raws li API 5L cov cai rau kev tsim cov kav dej.
