M'dziko lakupanga zitoliro zachitsulo, kumvetsetsa zamakampani ndi miyezo ndikofunika kwambiri pakuwonetsetsa kuti ntchito ndi yabwino. Muyezo umodzi woterewu ndi ASTM A139, womwe umafotokoza zofunikira pakuphatikizika kwamagetsi (arc) chitoliro chachitsulo chowotcherera kuti chigwiritsidwe ntchito mwamphamvu kwambiri. Blog iyi izama mozama muzofunikira za ASTM A139 ndikuwunika momwe imagwiritsidwira ntchito, makamaka potengera S235 J0 spiral steel pipe yopangidwa ndi wopanga wamkulu ku Cangzhou, Hebei Province.
Zofunikira zazikulu za ASTM A139
ASTM A139chimakwirira mbali zingapo zofunika kupanga zitsulo chitoliro, kuphatikizapo kapangidwe zinthu, katundu makina, ndi njira mayeso. Standard imayang'ana pazotsatira izi:
1. Zida Zopangira: ASTM A139 imatchula mankhwala achitsulo omwe amagwiritsidwa ntchito popanga mapaipi. Izi zikuphatikizapo malire ovomerezeka a zinthu monga carbon, manganese, phosphorous, ndi sulfure kuonetsetsa kuti mapaipi ali ndi mphamvu zofunikira komanso zolimba.
2. Katundu Wamakina: Mulingo uwu umafotokoza zofunikira zamakina, kuphatikiza mphamvu zokolola, kulimba kwamphamvu, ndi kutalika. Zinthuzi ndizofunikira kwambiri kuti chitolirocho chizitha kupirira ntchito zothamanga kwambiri popanda kulephera.
3. Zofunikira pakuwotcherera: Popeza ASTM A139 imagwira ntchito ndi mapaipi owotcherera, imaphatikizanso ndondomeko yowotcherera, kuphatikiza mtundu wa weld, weld quality, ndi njira zowunikira kuti zitsimikizire kuti zowotcherera zimakwaniritsa zofunikira.
4. Njira Zoyesera: Muyezowu umafotokozanso za njira zoyesera zomwe ziyenera kugwiritsidwa ntchito kutsimikizira momwe payipi ikuyendera. Izi zikuphatikiza njira zoyesera zosawononga kuti muwone zolakwika zilizonse mu ma welds kapena zida zamapaipi.
Kugwiritsa ntchito chitoliro chachitsulo cha ASTM A139
Kugwiritsa ntchito mapaipi achitsulo a ASTM A139 ndi otakata komanso osiyanasiyana, makamaka m'mafakitale omwe amafunikira makina opopera othamanga kwambiri. Mapaipi awa amagwiritsidwa ntchito kwambiri:
- Makampani a Mafuta ndi Gasi: Mapaipi a ASTM A139 ndi abwino kunyamula mafuta ndi gasi ndikutha kupirira zovuta komanso zovuta zachilengedwe.
- Njira Zoperekera Madzi: Kukhazikika ndi mphamvu zamapaipiwa zimawapangitsa kukhala oyenera kugwiritsidwa ntchito popereka madzi ndi kugawa, kuonetsetsa kuti madzi akuyenda odalirika.
- Chemical Processing: Muzomera zamakina, mapaipi amakhudzidwa ndi zinthu zowononga ndipo mapaipi a ASTM A139 amapereka kukana koyenera komanso kudalirika.
Ubwino wa S235 J0chitoliro chachitsulo chozungulira
Chimodzi mwazinthu zabwino kwambiri zopangidwa ndi kampani yathu ku Cangzhou ndi S235 J0 zitsulo zozungulira. Izi ndizodziwika kwambiri chifukwa cha kusinthasintha kwake m'mimba mwake komanso makulidwe a khoma. Kusinthasintha kwa kupanga kumapangitsa kuti apange mapaipi apamwamba kwambiri amipanda omwe amakwaniritsa zosowa zosiyanasiyana zamafakitale osiyanasiyana.
Yakhazikitsidwa mu 1993, patatha zaka zachitukuko chofulumira, kampaniyo tsopano ili ndi malo a 350,000 square meters, ili ndi chuma chonse cha RMB 680 miliyoni, ndipo ili ndi antchito odzipereka 680, odzipereka kupanga mapaipi apamwamba kwambiri omwe amakwaniritsa miyezo yapadziko lonse monga ASTM A139.
Pomaliza
Kumvetsetsa ASTM A139 ndi mafotokozedwe ake ndikofunikira kwa aliyense amene akuchita nawo ntchito yopanga zitoliro zachitsulo. Muyezo uwu sikuti umangotsimikizira ubwino ndi ntchito ya chitoliro, komanso imatsegula ntchito zambiri m'mafakitale osiyanasiyana. Ndi zinthu monga S235 J0 spiral steel pipe, kampani yathu ikupitiriza kutsogolera njira yopezera makasitomala njira zosinthika, zapamwamba kwambiri. Kaya muli mumakampani amafuta ndi gasi, madzi kapena kukonza mankhwala, mapaipi athu achitsulo adzakwaniritsa zosowa zanu ndikupitilira zomwe mukuyembekezera.
