Ipayipi lensimbi yekhabhoni le-ASTM A672 B60/B70/C60/C65/C70 LSAW(JCOE) yi-Carbon Steel Pipeisetshenziswa esimweni sokucindezela okuphezulu futhi isetshenziswa kakhulu esitshalweni sikagesi, embonini kawoyela ogwini lolwandle, embonini yamakhemikhali, kumanyolo, kumakhemikhali kaphethiloli, ezindaweni zokuhluza njll.
Ipayipi Lensimbi Yekhabhoni le-ASTM A672 B60/B70/C60/C65/C70 LSAW(JCOE) LSAW(JCOE) kufanele libe ama-weld afakwe kabili, angena ngokugcwele enziwe ngokuhambisana nezinqubo kanye nabashiseli noma opharetha bokushisela abafanelekile ngokuhambisana ne-ASME Boiler kanye ne-Pressure Vessel Code, Isigaba IX.
Zonke izinhlobo ngaphandle kuka-10, 11, 12 kanye no-13 kufanele ziphathwe ngokushisa esithandweni somlilo esilawulwa ku-±15℃ futhi zifakwe i-hydrometer yokurekhoda ukuze kutholakale amarekhodi okushisa.
Ukukhiqiza:Ukushisela kwe-Arc okucwiliswe emanzini isikhathi eside (i-LSAW).
Usayizi:I-OD: 406～1422mm Ubude: 8～60mm.
Izinga:I-B60, C60, C65, njll.
Ubude:3-12M noma ubude obucacisiwe njengoba kudingeka.
Uphela:Isiphetho Esilula, Isiphetho Esigobile, Esinemiphetho.

1. Ububanzi Bangaphandle - Ngokusekelwe ekulinganisweni okujikelezayo ±0.5% yobubanzi bangaphandle obucacisiwe.
2. Umehluko ongaphandle kobubanzi obukhulu nobukhulu obuncane bangaphandle.
3. Ukuqondanisa-Ukusebenzisa umphetho oqondile ongu-10 ft (3m) obekwe ukuze zombili iziphetho zithintane nepayipi, 1/8 in. (3mm).
4. Ubukhulu - Ubukhulu bodonga obuncane kunoma iyiphi indawo epayipini akumele bube ngaphezu kuka-0.01 in. (0.3mm) ngaphansi kobukhulu obubekiwe.
5. Ubude obuneziphetho ezingakashintshwa kufanele bube ngaphakathi kuka-0,+1/2 intshi (-0,+13mm) walokho okuchaziwe. Ubude obuneziphetho ezikashintshwa kufanele bube njengoba kuvunyelwene phakathi komenzi nomthengi.
Ukuhlolwa Kokucindezeleka—Izakhiwo zokudonsa eziguquguqukayo zejoyinti elihlanganisiwe zizohlangabezana nezidingo ezincane zamandla okudonsa aphelele ezinto ezishiwoyo zepuleti.
