ERW steel yeeb nkab rau lub nroog gas pipeline network tsim

"Lub Nroog Gas Design Code" muab cov kav dej xa hluav taws xob nrog lub siab siab dua 0.4Mpa.Lub siab yog tsawg dua 0.4Mpa siab thiab qis-siab gas pipeline yuav tsum siv polyethylene yeeb nkab, mechanical interface ductile hlau yeeb nkab, steel hlau los yog steel skeleton yas yeeb nkab.Rau cov kav dej rau kev thauj mus los hauv nroog, ERW steel yeeb nkab ntau dua 0.4Mpa siab yog nrog cov xwm txheej tsis sib haum xeeb piv rau lwm cov khoom siv hauv cov yeeb nkab steel.Yog li ntawd, ERW steel yeeb nkab yog lub nroog gas pipeline network tsim.

1, Nyob rau hauv cov nqe lus ntawm kev ruaj ntseg, rau lub nroog gas pipeline network lub ntsiab yeeb nkab, cov kabmob muaj peev xwm, tensile zog thiab elongation ntawm ERW steel yeeb nkab yog tag nrho cov nyob deb ntau tshaj cam khwb cia hlau yeeb nkab, thiab bearing muaj peev xwm, tensile zog thiab muaj peev xwm hloov mus rau. qhov sib txawv ntawm qhov kub thiab txias ntau dua "PE" yeeb nkab;thiab nyob rau hauv cov nqe lus ntawm lub interface rigors, ERW steel yeeb nkab weld interface yog nyob deb npaum li cas ze tshaj cov cam khwb cia hlau yeeb nkab, thiab ntau yam khoom;

2, nyob rau hauv cov nqe lus ntawm adaptability, ERW steel yeeb nkab yog haum rau roj, LNG, LPG, liquefied natural gas thiab cua sib tov, thiab cam khwb cia hlau yeeb nkab ntawm lub peev xwm los hloov mus rau LNG thiab natural gas yog ntau tsawg;ERW steel yeeb nkab muaj peev xwm hloov mus rau qhov kub thiab txias ntau dua li "PE" yeeb nkab.

3, Nyob rau hauv cov nqe lus ntawm kev lag luam, ERW steel yeeb nkab yog pheej yig dua li cov yeeb nkab hlau.Thiab thaum ntau tshajφ160, ERW steel yeeb nkab kuj tseem pheej yig dua li "PE" yeeb nkab (feem ntau hais lus, feem ntau ntawm lub nroog cov yeeb nkab loj.φ300 los yog ntau tshaj).

4, corrosion kuj ntawm ERW steel yeeb nkab tsis zoo li cam khwb cia hlau yeeb nkab thiab "PE" yeeb nkab, uas yog ib qho tseem ceeb qhov teeb meem kom paub tseeb tias yuav coj ib tug zoo tiv thaiv corrosion nyob rau hauv lub tsim thiab kev tsim kho.
