Imikhiqizo Yethu Ehlobene
Ububanzi be-ASTM A106
Uhlobo lwepayipi: ipayipi lensimbi engenamthungo.
NI-ominal Pipe Usayizi: Imboza ipayipi lensimbi elingenamthungo kusuka ku-DN6-DN1200 (NPS1/8-NPS48).
Ukuqina Kodonga: Ukujiya kodonga kuyadingeka ukuze kuhlangatshezwane nezidingo ezithile zeThebula 1 laI-ASME B36.10M.
Ibanga le-ASTM A106
I-ASTM A106 inamabanga amathathu wepayipi lensimbi: IBanga A,Ibanga B, kanye neBanga C.
Umehluko omkhulu phakathi kwamabanga amathathu ukwakheka kwamakhemikhali kanye nezakhiwo zemishini.
Izinto ze-ASTM A106 Raw
Insimbi izobulawa insimbi.
Insimbi ikhiqizwa kusetshenziswa inqubo yokuqala yokuncibilika, okungaba indawo evulekile, i-basic-oxygen, noma isithando somlilo sikagesi, okungenzeka kuhlanganiswe nokukhipha umoya okuhlukile noma ukucwengwa.
I-ASTM A106 Indlela Yokukhiqiza Ipayipi Lensimbi engenamthungo
Ipayipi lensimbi elingenamthungoikhiqizwa ngezindlela ezimbili: idonswa kubanda futhi iphelile ngokushisa.
DN ≤ 40mm ipayipi lensimbi elingenamthungo lingadonswa ngokubanda noma lishise.
I-DN ≥ 50mm ipayipi yensimbi engenamthungo iphelile ngokushisa.
Ukwelashwa Okushisayo
Ipayipi lensimbi elingenamthungo eliqedwe ukushisa le-ASTM A106 alidingi ukwelashwa kokushisa.
Amashubhu ensimbi angenamthungo adonswa ngokubanda e-ASTM A106 adinga ukuphathwa ngokushisa emazingeni okushisa angu-≥ 650°C.
Ukwakheka Kwamakhemikhali
I-ASTM A106 IBanga A, iBanga B, neBanga C ekwakhiweni kwamakhemikhali umehluko omkhulu umehluko phakathi kokuqukethwe kwe-C ne-Mn, okuqukethwe kwezinye izakhi emabangeni ahlukahlukene kungase kube nomehluko omncane, kodwa ngokuvamile ukulawula ububanzi obuphansi kakhulu.
Izakhiwo Zemishini
Ubuncane bebude obungu-2 in. (50 mm) buzonqunywa ngezibalo ezilandelayo:
amayunithi angama-inch-pound:
e=625,000A0.2/UO.9
Sl amayunithi:
e=1940A0.2/U0.9
e: ubude obuncane ngamayintshi angu-2. (50 mm), %, ifinyezwe ku-0.5% eseduze
A: indawo ephambanayo yesampula yokuhlolwa kwengcindezi, ku2(mm2）ngokusekelwe kububanzi obushiwo bangaphandle noma ububanzi besampula obujwayelekile kanye nokuqina kodonga olucacisiwe,izungezwe ibe ngu-0.01 in2(1 mm2).
Uma indawo ebalwe kanjalo ilingana noma inkulu kuno-0.75 in2(500 mm2), bese kuba inani elingu-0.75 in2(500 mm2) kuzosetshenziswa.
U: amandla e-tensile acacisiwe, i-psi (MPa)
Uhlelo Lokuhlola
I-ASTM A106 iqukethe imininingwane eningiliziwe yokwakheka kwamakhemikhali, ukuhlaziya okushisayo, izidingo zempahla engumshini, izidingo zokugoba, izivivinyo zokucaba, izivivinyo ze-hydrostatic, nokuhlolwa kukagesi okungabhubhisi.
Ukwakheka Kwamakhemikhali / Ukuhlaziywa Kokushisa
Ukuhlaziywa Kokushisa kuyinqubo esetshenziselwa ukunquma okuqukethwe kwezakhi zamakhemikhali ngazinye kunsimbi ukuze kuqinisekiswe ukuthi ukwakheka kwamakhemikhali kwenqwaba yezinto ezibonakalayo kuhlangabezana nezimfuneko ze-ASTM A106.
Ukunqunywa kokwakheka kwamakhemikhali kusekelwe ekuhlaziyeni okushisayo.Ukugxila okuyinhloko kokuqukethwe kwezakhi ze-carbon, i-manganese, i-phosphorus, isulfure, ne-silicon, izilinganiso zazo ezinomthelela oqondile ezindaweni zepayipi.
Izidingo ze-Tensile
Amashubhu kufanele ahlangabezane namandla athile aqinile, amandla esivuno, kanye nezidingo zobude.Lokhu kuqinisekisa amandla nokuqina kweshubhu emazingeni okushisa aphakeme.
Izidingo zokugoba
Ukuhlolwa kokugoba kusetshenziselwa ukuhlola ukuqina kanye nokuguqulwa kwepulasitiki kwamashubhu lapho engaphansi kokucindezeleka okugobayo ukuze kuqinisekiswe ukwethembeka kweshubhu ngesikhathi sokufakwa nokusetshenziswa.
Ukuhlola Ukucaba
Izivivinyo zokucaba zisetshenziselwa ukuhlola ukudumba nokumelana nokuqhekeka kwamashubhu ensimbi.Lokhu kuhlolwa kudinga ukuthi ipayipi ifakwe isicaba ngezinga elithile ngaphandle kokuqhekeka ukuze kufakazele ikhwalithi yezinto kanye nokufaneleka kobuchwepheshe bokucubungula.
Ukuhlolwa kwe-Hydrostatic
Ukuhlolwa kwe-Hydrostatic kuyisinyathelo esibalulekile ekuhloleni umthamo othwala ingcindezi wepayipi lensimbi ngokusebenzisa ingcindezi ephakeme kunaleyo edingwa yizinga ukuze kuqinisekiswe ubuqotho bayo besakhiwo kanye nokungabikho kokuvuza.
Ukuhlola Ugesi Okungabhubhisi
I-Nondestructive Electric Test (isb. ukuhlolwa kwe-ultrasonic noma ukuhlolwa kwe-electromagnetic) isetshenziselwa ukukhomba amaphutha angaphakathi nangaphezulu njengokuqhekeka, okufakiwe, noma izimbobo zamashubhu ensimbi ukuze kuqinisekiswe ikhwalithi yomkhiqizo.
I-Dimensional Tolerances
IMisa
Isisindo sangempela sepayipi kufanele sibe kububanzi be97.5% - 110%yenqwaba eshiwo.
Amapayipi ku-NPS 4 [DN 100] nangaphansi angakalwa ezindaweni ezikahle;
Amapayipi amakhulu kune-NPS 4 [DN 100] azokalwa ngokuhlukana.
Ububanzi bangaphandle
Kumashubhu e-OD > 250 mm (10 in), uma kudingeka ukunemba okuphezulu kwe-OD, ukuhluka okuvumelekile kwe-OD kungu-±1%.
Kumashubhu e-ID > 250 mm (10 in), uma kudingeka ukunemba okuphezulu kwe-ID, ukuhluka kwe-ID okuvunyelwe ngu-±1%.
Ubukhulu
Ubuncane bodonga oluwugqinsi = 87.5% wobukhulu obucacisiwe bodonga.
Ubude
Ubude obungahleliwe obubodwa: 4.8-6.7 m [16-22ft].Ubude obungu-5% buvunyelwe ukuba bube ngaphansi kuka-4.8 m [16 ft], kodwa bungabi bufishane kuno-3.7 m [12 ft].
Ubude obuphindwe kabili obungahleliwe: Ubude obuncane obumaphakathi bungu-10.7 m [35 ft] kanti ubude obuncane bungamamitha angu-6.7 [22 ft].Amaphesenti amahlanu obude avunyelwe ukuthi abe ngaphansi kwamamitha angu-6.7 [22 ft], kodwa angabi mafishane kuno-4.8 m [16 ft].
Ukwelashwa Kokukhubazeka Okungaphezulu
Ukunqunywa Kweziphambeko
Uma ukonakala kwendawo kwenzeka kumashubhu adlula u-12.5% wogqinsi oluvamile lodonga noma ukweqa ubukhulu obuncane bodonga, amaphutha kufanele asuswe ngokugaya inqobo nje uma ugqinsi olusele luyi-87.5% noma ngaphezulu kwenani elishiwo lokujiya.
Amaphutha angalimazi
Ukwenza ukwelashwa okungaphezulu kuhambisane nezidingo zenqubo, amaphutha alandelayo angalimazi kufanele asuswe ngokugaya:
1. Izimpawu zemishini kanye nemihuzuko - njengamamaki ekhebula, amabobo, amamaki okuqondisa, ama-rolling mark, ukuklwebheka kwebhola, ama-indent kanye nama-mold marks, kanye nemigodi, okungekho kuyo okuzodlula u-1/16 ku-(1.6mm) ukujula.
2. Ukungapheleli okubukwayo, ikakhulukazi ama-crust, ama-seams, ama-laps, izinyembezi, noma izingcezu ezijule kunamaphesenti angu-5 ogqinsi lwezindonga.
Ukulungiswa Kwesici
Lapho amabala noma ukukhubazeka kususwa ngokugaya, indawo egobile ebushelelezi kufanele igcinwe futhi ukushuba kodonga lwamapayipi akumele kube ngaphansi kuka-87.5% yenani eliwugqinsi olucacisiwe.
Ukulungisa ama-welds kwenziwa ngokuhambisana ne-ASTM A530/A530M.
Ukumaka kweThubhu
Ipayipi ngalinye lensimbi le-ASTM A106 lizomakwa ngokuhlonzwa komkhiqizi, izinga elibekiwe, ubukhulu, kanye nolwazi lwebanga leShejuli ukuze kukhonjwe kalula futhi kulandeleke.
Ukuhlolwa kukagesi we-hydrostatic noma okungabhubhisi okumaka le mithetho elandelayo kufanele ilandelwe:
| I-Hydro | NDE | Ukumaka |
| Yebo | No | Ingcindezi Yokuhlola |
| No | Yebo | NDE |
| No | No | NH |
| Yebo | Yebo | Ingcindezi Yokuhlola/NDE |
