Ob leeg sab hauv thiab sab nrauv ntawm cov yascoated steel yeeb nkab yog coated nrog epoxy resin, nto yog du, cov kua kuj yog txo, qhov txaus tus nqi yog nce, tsis muaj scale yog tsim, thiab microorganisms feem ntau tsis loj hlob.Kev pabcuam lub neej ntawm cov dej tua hluav taws (gas) cov kav dej tau txhim kho zoo heev los ntawm cov txheej txheem yas ntawm kev xa dej, cov yeeb nkab faus, kua qaub, alkali, thiab ntsev corrosion ntawm cov dej tua hluav taws (gas) pipeline.Lub neej kev pabcuam tuaj yeem ncav cuag ntau dua 50 xyoo.Lub siab ntau ntawm cov kav hluav taws xob yog 0-2.5mp.Hluav taws kub-tawv yas-coated steel kav yog raws li cov kav hlau.Sab nrauv phab ntsa txais cov thermosetting hmoov txheej, uas muaj adhesion siab, cuam tshuam tsis kam, corrosion kuj, thiab huab cua tsis kam.Sab hauv phab ntsa txais cov hmoov txheej thermoplastic nrog cov adhesion siab, corrosion kuj, thiab kev tu cev ntawm cov zaub mov.Sab hauv thiab sab nrauv yas coated steel kav dej yog tsim los ntawm sandblasting tshuaj ob chav pretreatment, preheating, puab thiab txheej yas txheej, kho, tom qab kho, thiab lwm yam txheej txheem.Nws yog cov khoom lag luam raug nqi hloov khoom dua tshiab los ntawm cov yeeb nkab steel-yas thiab cov yeeb nkab galvanized.Cov khoom tau dhau lub teb chaws cov khoom tua hluav taws tua hluav taws cov ntawv pov thawj kev tshaj lij thiab cov khoom siv hluav taws xob refractory zoo tshuaj xyuas chaw.
