ASTM A53 yopanda chitsulo chitoliro ndi mtundu wamba waku America. A53-F imagwirizana ndi zinthu za Q235 za ku China, A53-A imagwirizana ndi zinthu za China No.
Njira yopanga
Chitoliro chopanda msokonezo chopangira chitoliro chimagawidwa mu chitoliro chotentha komanso chozizira chopanda msoko.
1. Njira yopangira chitoliro chachitsulo chosasunthika chotentha: chubu billet → kutentha → perforation → zodzigudubuza zitatu/kugudubuza & kugudubuza mosalekeza → de-pipe → sizing → kuzizira → kuwongola → kuyezetsa hydraulic → chizindikiro → chitoliro chachitsulo chosasokonekera ndi mphamvu zopezeka.
2. Njira yopangira machubu achitsulo osasunthika ozizira omwe amakokedwa: chubu chopanda kanthu → kutentha → kuphulika → mutu → kupukuta → pickling → kupaka mafuta → zojambula zambiri zozizira → chubu chopanda kanthu → chithandizo cha kutentha → kuwongola → kuyesa kwa hydraulic → kulemba → kusunga.
Mapulogalamu
1. Kumanga: mapaipi apansi, madzi apansi panthaka, ndi kayendedwe ka madzi otentha.
2. Kukonza makina, kunyamula manja, makina opangira makina, ndi zina zotero.
3. Zamagetsi: Kutumiza gasi, payipi yamadzimadzi amagetsi a Hydroelectric
4. Anti-static machubu opangira magetsi amphepo, etc.
