Siqhubeka "nekhwalithi ephezulu, ukulethwa okusheshayo, intengo enamandla", sesisungule ukubambisana kwesikhathi eside namakhasimende avela kwamanye amazwe kanye nasekhaya futhi sithola imibono emihle yamakhasimende amasha namadala.Amapayipi Angenamthungo aseShayina kanye nepayipi lensimbi, Sihlose ukuba yibhizinisi lesimanje elinenhloso yezentengiselwano ethi “Ubuqotho nokuzethemba” kanye nomgomo “wokunikeza amakhasimende izinsizakalo eziqotho kakhulu kanye nemikhiqizo esezingeni eliphezulu”. Sicela ngobuqotho ukwesekwa kwakho okungashintshiwe futhi siyabonga ngeseluleko sakho esinomusa kanye nesiqondiso.
Amapayipi a-odiwe ngaphansi kwale ncazelo asetshenziselwa isevisi yokucindezela okuphezulu emazingeni okushisa omoya naphansi. Asetshenziswa kakhulu ekudlulisweni kukawoyela negesi yemvelo.
I-ASTM A671Ipayipi Lensimbi Yekhabhoni le-LSAW(JCOE)kufanele kube ukushisela okufakwe kabili, okugcwele okwenziwe 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: Amapayipi ensimbi e-LSAW(JCOE)
Usayizi: OD: 406~1500mm Isisindo: 6~40mm
Ibanga: CB60, CB65, CC60, CC65, njll.
Ubude: 12M noma ubude obucacisiwe njengoba kudingeka.
Iziphetho: Isiphetho Esilula, Isiphetho Esigobile, Esinemiphetho Emikhulu;

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.
