Sab hauv tus neeg xyuas pib, sab nraud neeg xyuas pib, insulating nruab nrab, sheath
Tooj liab yog qhov khoom tseem ceeb ntawm tus neeg xyuas pib sab hauv: annealed tooj liab hlau, annealed tooj liab raj, thiab tooj liab-clad txhuas hlau xaim.
Tus neeg xyuas pib sab nraud feem ntau yog ntev li nrog daim ntaub xev. Ntawm cov txheej txheem ntawm cov neeg xyuas pib sab nraud, muaj cov lus qhia ntev lossis hla mus lossis cov qhov me me.
Cov khoom siv txau siv rau cov ntaub thaiv sab nraum zoov yog cov kab dub dub qis polyethylene. Nws cov ntom ntab zoo sib xws rau LDPE, tab sis nws lub zog yog sib npaug rau HDPE. Ntawm qhov tsis sib xws, qee qhov xwm txheej, peb nyiam siv HDPE, uas tuaj yeem muab cov khoom zoo dua qub thiab muaj peev xwm tiv thaiv kev txhuam, tshuaj lom neeg, dej noo thiab qhov sib txawv ntawm ib puag ncig rau cov kab xev.
