I-ASTM A106 Umbhobho ongenamthungo - IBLOGU

I-ASTM A106 ngumbhobho oqhelekileyo we-carbon steel umthungo uninzi lwabayili bachaza xa umgca kufuneka uphathe ulwelo olushushu okanye igesi phantsi koxinzelelo. Yenzelwe ubushushu obuphakamileyo-inkonzo, inomlinganiselo ngokuhambelana ne-ASME B36.10M, kwaye inokunikezelwa ngeziphelo ezicacileyo okanye ezibeveled zokuwelda, ukugoba kunye nokujingisa. Phakathi kwamaBanga A, B kunye no-C kwi-ASTM A106, iBanga B lisetyenziswa kakhulu kuba linika umxube othembekileyo wamandla, i-ductility kunye ne-weldability yemigca yomphunga, iiheader zokucoca, imibhobho yenkqubo kunye neesekethe zeplanti yamandla.

Imigangatho kunye nonikezelo

Umgangatho: ASTM A106 / ASME SA106
IBanga: B (ikwafumaneka ngo-A, C ukuba iprojekthi iyavuma)
Imo: Ayinamthungo, ishushu-igqityiwe okanye iyabanda{1}igqityiwe
Ukuphela: Isiphelo esicacileyo (PE) okanye i-beveled end (BE) ye-welding
Imilinganiselo: ASME B36.10M, NPS kunye neshedyuli-esekelwe

Ukuqulunqwa kwemichiza

Umgangatho usekwe kuyilo olulula,{0}olulawulwa kakuhle lwekhabhoni-manganese-silicon. Ulawulo lwe-P kunye ne-S lugcina umbhobho weldable kwaye unzima.

IBanga	C (%)	Mnu (%)	P (%) max	S (%) ubuninzi	Si (%) umz
A	Ngaphantsi okanye ilingana no 0.25	0.27–0.93	0.035	0.035	0.10
B	Ngaphantsi okanye ilingana no 0.30	0.29–1.06	0.035	0.035	0.10
C	Ngaphantsi okanye ilingana no 0.35	0.29–1.06	0.035	0.035	0.10

Kutheni le nto ibalulekile: ikhabhoni inika ibakala amandla ayo asisiseko; i-manganese inceda ukuzinzisa isakhiwo se-ferrite-pearlite kunye nokuphucula ukuqina; I-silicon iphucula ukuxhathisa isikali/i-oxidation xa umbhobho uphethe umphunga oshushu okanye inkqubo yemidiya.

Iipropati zoomatshini

IBanga B libakala "eliphakathi" kodwa sele lomelele ngokwaneleyo kuninzi lwezicelo zezityalo.

IBanga	Amandla Okuqina (MPa)	Isivuno Amandla (MPa)	Ubude (%)
A	Inkulu kuno okanye ilingana nama 330	Inkulu kuno okanye ilingana no 205	Inkulu kuno okanye ilingana no 20
B	Inkulu kuno okanye ilingana no 415	Inkulu kuno okanye ilingana nama 240	Inkulu kuno okanye ilingana no 20
C	Inkulu kuno okanye ilingana nama 485	Inkulu kuno okanye ilingana nama 275	Inkulu kuno okanye ilingana no 20

Ukutolikwa koyilo kunye nokwakhiwa: amandla okuqina akhusela ukuqhuma kunye nemithwalo ye-axial; Amandla esivuno ngumda phambi kotshintsho olusisigxina, lubaluleke kakhulu kuxinzelelo oluphezulu{0}lokuqhuba; Ubude buqinisekisa ukuba umbhobho unokugotywa, udityaniswe kwaye ufakwe ngaphandle kokuqhekeka.

Ukusebenza kwiNkonzo yoBubushushu obuPhezulu{0}
I-A106 iBanga B yenzelwe ukuba ihlale kwinkonzo kumaqondo obushushu entsimbi ukuya kuthi ga kwi-400–450℃band. Kweli nqanaba i-ferrite-pearlite microstructure ihlala izinzile, isilicon inceda umphezulu ukuxhathisa ukukala, kwaye umbhobho ugcina uxinzelelo lwawo{4}}ukuthwala amandla. Yiyo loo nto ixelwa kwimigca yesondlo sebhoyila, iiheader zomphunga, ubushushu-umbhobho otshintshisayo, inkonzo ye-oyile eshushu kunye neenkqubo eziluncedo zokucoca. Nge-PWHT efanelekileyo kunye neenkqubo ze-welding, umbhobho unokuqhuba kwakhona kwinkonzo ye-cyclic ngaphandle kokulahlekelwa ngokukhawuleza kokuqina.

Ukuvelisa kunye noNyango loBushushu

KwiBanga le-A106 iBanga B indlela yokuvelisa ayikho indawo yokuncedisa - kungenxa yesizathu sokuba umbhobho unokusebenza ngokwenene kwiqondo lokushisa eliphezulu kunye noxinzelelo. Indlela yokusila eqhelekileyo ye-A106 yeBanga B engenamthungo kwi-Octal Pipe ijongeka ngolu hlobo:

1. Ukukhetha i-billet kunye nolawulo lwekhemistri
Imveliso iqala ekubulaweni (ideyoxidized ngokupheleleyo), iibhilithi zentsimbi yekhabhoni ecocekileyo-esele idibana noluhlu lweekhemikhali ze-A106. Oku kuqinisekisa i-P kunye ne-S ephantsi, ukucoceka okulungileyo kunye nokuvutha. Ubushushu buyajongwa phambi kokuba buqengqeleke ukuze iithagethi zoomatshini zeBanga B zinokufikelelwa emva kokubunjwa kunye nonyango lobushushu.

2. Billet ukufudumeza
Iibhilithi zifudunyezwa kwirotary okanye{0}}ehambayo{0}}kwiziko lokuhamba ukuya kubushushu bokugqobhoza/ukuqengqeleka. Ukufudumeza okufanayo kubalulekile apha kuba ubushushu obungalinganiyo bunokubangela udonga -ukutyeba okuguquguqukayo xa ibhilethi igqojozwa.

3. Ukugqobhoza okushushu (ukwenza umngxuma)
Ibhilethi eshushu igqojozwe kumnqamlezo -umqulu okanye i-mandrel piercing mill ukwenza iqokobhe elinomgongxo. Kulapho umbhobho ujika usuka kumjikelo oqinileyo ube ityhubhu engenamthungo. Injongo kukuvelisa iqokobhe elingagqabhukanga embindini kunye nodonga olulinganayo olujikeleze isangqa.

4. Elongation kunye iplagi / mandrel rolling
Iqokobhe elimngxuma ke ngoko lilondolozwe kwaye liqengqeleke phezu kwe-mandrel okanye iplagi yokusila ukufikelela kufutshane nobubanzi obuyalelweyo kunye nobukhulu bodonga. Iindawo ezininzi zokuqengqeleka zingasetyenziselwa ukucokisa udonga nokuphucula umphezulu. Eli nyathelo liyisitshixo sokwenza umphezulu wangaphakathi ube mpuluswa kunye nokugcina ubukhulu bodonga ngaphakathi kokunyamezela.

5. Ubungakanani/ukunciphisa ilitye lokusila
Ilitye lokusila okanye lokunciphisa lizisa umbhobho kwi-OD yayo yokugqibela kunye nokungqukuva. Kwiishedyuli eziphakamileyo (iindonga ezityebileyo), iiparamitha eziqengqelekayo zihlengahlengiswa ukuze kugcinwe ukugxila. Ukulinganisa okuchanekileyo apha kuthetha ukuwelda lula kunye nokufaneleka ngcono{2}}kwisayithi.

6. Ukupholisa kunye nokulungelelanisa
Emva kokusebenza okushushu, imibhobho ipholile ngendlela elawulwayo kwaye idlule kumatshini wokulungisa. Ukuthe tye kubalulekile kwiispools ezenziwe ngaphambili kunye ne-welding ezenzekelayo.

7. Unyango lobushushu (njengoko kufuneka)
Kuxhomekeka kubungakanani bombhobho, umlinganiselo wokucutha kunye nemfuno yomthengi, imibhobho inokwenziwa njengesiqhelo okanye uxinezeleko{0}}luthotywe.

Ukuqhelanisa kuphucula ukwakheka kwe-ferrite-pearlite, ukulinganisa iipropathi ngobude kunye nokuphucula ukuqina.

Uncedo loxinzelelo lususa ukwenza uxinzelelo, oluluncedo ukuba umbhobho uya kudityaniswa kwisixokelelwano esiya kuthi kamva sibone ukujikeleza kwe-thermal.
Olu nyango lulawulwayo lobushushu yinto enceda i-A106 yeBanga B igcine i-ductility yayo kunye nokumelana nempembelelo kwinkonzo eshushu.

8. Ukugqiba, i-NDE kunye ne-hydrotest
Imibhobho egqityiweyo inqunywe ubude, iziphelo zijongene / zibethelwe, kwaye ubude ngamnye buhlolwe ngokubonakalayo ngokuchaneka komphezulu kunye nobukhulu. Emva koko umbhobho uyavavanywa:

uvavanyo lwe-hydrostatic ukubonisa ukunyanzeliswa koxinzelelo
eddy{{0}yangoku okanye i-ultrasonic NDE ukujonga iziphene zangaphakathi/umphezulu
ukuphawula kunye nokugquma / i-varnish yokukhusela
Kuphela emva kokuba onke la manyathelo akhutshwe umbhobho nge-MTC.

Ngenxa yokuba yonke indlela ingenamthungo (akukho weld yobude), umbhobho unokumelana okufanayo koxinzelelo malunga nesekelo esipheleleyo - esona sizathu siphambili i-A106 ikhethwe kumbhobho odityanisiweyo wenkonzo{1}}yobushushu obuphezulu.
