Ukukhethwa okulungile kwamapayipi ensimbi angenamthungo empeleni kunolwazi kakhulu!

Yiziphi izidingo zokukhetha amapayipi ensimbi angenamthungo okuthutha uketshezi oluvame ukusetshenziswa embonini yethu yezinqubo?Bheka isifinyezo sabasebenzi bethu bePress Pipeline:

Amapayipi ensimbi angenamthungo amapayipi ensimbi ngaphandle kokushisela akhiwe ngezindlela zokwelapha ezishisayo njengokubhoboza nokuginqika okushisayo.

Uma kunesidingo, ipayipi yokwelapha eshisayo ingaqhubeka nokubanda-idonseleka esimweni esidingekayo, ubukhulu kanye nokusebenza.Njengamanje, amapayipi ensimbi angenamthungo (DN15-600) angamapayipi asetshenziswa kakhulu emishinini yokukhiqiza i-petrochemical.

Ububanzi bokusebenza: i-steam medium eshisa kakhulu ye-boiler yokucindezela okuphezulu

Ukuhlola: Ngokuvamile amapayipi ensimbi okuthutha uketshezi kufanele ahlaziywe ukwakheka kwamakhemikhali, ukuhlolwa okuqinile, ukuhlolwa kokucaba kanye nokuhlolwa kwe-hydraulic.I-GB5310, GB6479, kanye ne-GB9948 amapayipi ensimbi ajwayelekile, ngaphezu kokuhlolwa okufanele kwenziwe kumapayipi ensimbi okuthutha uketshezi, ukuhlolwa kokuvutha kanye nokuhlolwa komthelela nakho kuyadingeka;Izidingo zokuhlola zokukhiqiza zalawa mapayipi amathathu ensimbi ziqinile.Izinga le-GB6479 libuye lenze izidingo ezikhethekile zokuba nethonya lokushisa eliphansi lokuzivocavoca.Ngaphezu kwezidingo ezijwayelekile zokuhlolwa kwamapayipi ensimbi okuthutha uketshezi, amapayipi ensimbi wezinga le-GB3087 nawo adinga ukuhlolwa kokugoba okubandayo.Amapayipi ensimbi ajwayelekile e-GB/T8163, ngaphezu kwezidingo ezijwayelekile zokuhlola amapayipi ensimbi ezokuthutha uketshezi, ngokuvumelana nesivumelwano kudinga ukuhlolwa kokunwetshwa kanye nokuhlolwa kokugoba okubandayo.Izidingo zokukhiqiza zalezi zinhlobo ezimbili zamashubhu azinamandla njengezinhlobo ezintathu zokuqala.

Ezokukhiqiza: I-GB / T8163 ne-GB3087 Amapayipi ensimbi ajwayelekile akhunjulwa kakhulu endaweni evulekile noma ekuguqulweni, futhi ukungcola kwawo kanye nokungcola kwangaphakathi kukhulu.I-GB9948 ikakhulukazi isebenzisa ukubhema isithando somlilo kagesi.Iningi labo lijoyine inqubo yokucwenga ngaphandle kwesithando somlilo, futhi ukwakheka kanye namaphutha angaphakathi kuncane kakhulu.Amazinga e-GB6479 kanye ne-GB5310 ngokwawo abeka izimfuneko zokucwengisiswa ngaphandle kwesithando somlilo, ngokwakhiwa kokungcola okuncane kanye namaphutha angaphakathi, kanye nekhwalithi ephezulu kakhulu yezinto ezibonakalayo.

Ukukhetha: Ngokuvamile, i-GB / T8163 I-Standard Steel Pipe ilungele uwoyela, uwoyela negesi kanye nemidiya yomphakathi ngokushisa komklamo ongaphansi kwama-350 ° C kanye nengcindezi engaphansi kwe-1050Kuma-oyili, amafutha kanye namagesi, lapho izinga lokushisa lokuqamba lidlula ama-350 ° C noma lapho ingcindezi inkulu kune-10.0MPA, i-GB6479 kufanele isetshenziswe amapayipi ensimbi;Kumapayipi asebenza ku-hydrogen, noma amapayipi asebenza ezindaweni zokugqwala zokugqwala, amazinga we-GB9948 noma i-GB6479 kufanele futhi asetshenziswe.Wonke amapayipi ensimbi e-carbon asetshenziswe emazingeni okushisa aphansi (ngaphansi kuka-20 ° C) kufanele amukele okujwayelekile kwe-GB6479Amazinga we-GB3087 kanye ne-GB5310 amazinga asethelwe ngqo amapayipi ensimbi.I- "Boiler Safety Supperingotion Regations" igcizelela ukuthi wonke amapayipi axhunywe kwi-boiler engowasezingeni lokugadwa, kanye nokusetshenziswa kwezinto zokwakha kanye namazinga kufanele ahambisane nezidingo ze- "Boiler Safety Support Regules".Ngakho-ke, zisetshenziswa kuma-boilers, iziteshi zamandla, ukufudumeza kanye nezindawo zokukhiqiza ze-petrochemical.Onke amapayipi omphakathi asemuva (ahlinzekwe ngohlelo) kufanele amukele amazinga we-GB3087 noma GB5310.Kuyaqapheleka ukuthi intengo yamapayipi ensimbi anezindinganiso ezinhle zensimbi ephezulu kakhulu.Isibonelo, intengo ye-GB9948 icishe ibe ngu-1/5 iphakeme kunentengo yezinto zokwakha ze-GB8163.Ngakho-ke, lapho ukhetha amazinga wensimbi wamapayipi wensimbi, ukucatshangelwa okuphelele kufanele kunikezwe imibandela yokusebenzisa, okumele ibe nokwethenjwa futhi ibe nezengqondo.Kufanele futhi kuqashelwe ukuthi amapayipi ensimbi ngokuya nge-GB / T20801 ne-TSGD0001, i-GB3087 kanye nama-GB8163 amazinga angeke asetshenziselwe i-GC1. Isetshenziselwa i-GC1 enengcindezi yokuqamba hhayi enkulu kune-4.0mpa pipeline).

(二)Ipayipi le-alloy eliphansi elingenamthungo lensimbi

Emishinini yokukhiqiza ye-petrochemical, insimbi evame ukusetshenziswa i-chromium-molybdenum kanye ne-chromium-molybdenum-vanadium steel ipayipi elingenamthungo amazinga angu-GB9948 “ipayipi lensimbi elingenamthungo lokuqhekeka kwe-petroleum” GB6479 “Ipayipi lensimbi elingenamthungo elinomfutho omkhulu wezisetshenziswa zikamanyolo” GB/T5310 “Ingenamthungo ipayipi lensimbi le-boiler ephezulu yengcindezelo》I-GB9948 iqukethe amamaki ensimbi ezibonakalayo ze-chromium-molybdenum: I-12CRMO, i-1CRMO, 1CRMO, 1CR5MO, njll. Amabanga abonakalayo: I-15mog, 20mog, i-12CRMOG, i-15CRMOG, 12CRMOG, 12CRMOG, 12CRMOG, njll.

(三) Ipayipi lensimbi engenasici

Izindinganiso zamapayipi ensimbi engenamthungo asetshenziswa ngokuvamile yilezi:

Kunamazinga amahlanu: GB/T14976, GB13296, GB9948, GB6479, kanye ne-GB5310.Phakathi kwawo, yizigaba ezimbili kuphela noma ezintathu zensimbi engagqwali abalwe emazingeni amathathu okugcina, futhi awawona amamaki ezinto ezisetshenziswa kakhulu.

Ngakho-ke, lapho amazinga epayipi lensimbi engenamthungo esetshenziswa kwezobunjiniyela, amazinga e-GB/T14976 kanye ne-GB13296 asetshenziswa ngokuyisisekelo.

I-GB/T14976 “Ipayipi lensimbi engenamthungo yokuthutha uketshezi”:

Amabanga wezinto ezibonakalayo: 304, 304L nezinye izinhlobo eziyi-19 zilungele ukuthuthwa okujwayelekile koketshezi.

I-GB13296 “Amashubhu ensimbi engenamthungo angenamthungo wamabhayela nezishintshisi zokushisa”:

Amabanga abonakalayo: 304, 304L kanye nezinye izinhlobo ezingama-25.

Phakathi kwazo, i-ultra-low-carbon stainless steel (304L, 316L) inokumelana nokugqwala okuhle kakhulu.Ngaphansi kwezimo ezithile, ingathatha indawo yensimbi engagqwali ezinzile (321, 347) yokumelana nokugqwala kwabezindaba;I-Ultra-Low-Carbon Stainless yensimbi inezindawo eziphansi ezishisa kakhulu, ngokuvamile ezisetshenziswa kuphela emazingeni okushisa angaphansi kuka-525 ℃;insimbi engagqwali eqinile ye-austenitic inokubili ukumelana nokugqwala okuhle kanye nezakhiwo zomshini wokushisa okuphezulu, kepha i-Ti in 321 ifakwa i-oxidized kalula futhi ilahleke ngesikhathi sokushisela, Ngaleyo ndlela yehlisa ukusebenza kwayo okulwa nokugqwala, intengo yayo iphezulu uma kuqhathaniswa, lolu hlobo lwempahla luvame ukusetshenziswa ezindaweni eziningi. Izikhathi ezibalulekile, 304, 316 zinokusebenza okujwayelekile kokulwa nokuwohloka, intengo ishibhile, ngakho-ke isetshenziswa kabanzi.
