Cold Drawn Seamless Mechanical Tubing

Kugudubuza molimba mpukutu angagwiritsidwe ntchito ngati zopangira za otentha-kuviika galvanizing chomera, otentha dip galvanizing mzere anapereka annealing mzere. Kulemera kwa rolling hard roll nthawi zambiri kumakhala matani 6 mpaka 13.5, m'mimba mwake ndi 610mm.

Mkhalidwe wotumizira:

Nthawi	Chizindikiro	Kufotokozera
Kuzizira-kumaliza/zovuta (kuzizira komaliza ngati kukokedwa)	BK	Palibe chithandizo cha kutentha pambuyo pa kuzizira komaliza kupanga ndondomeko. Chifukwa chake, machubu amakhala ndi kuwonongeka kochepa chabe.
Zozizira zomaliza/zofewa (yogwira ntchito mopepuka)	BKW	Pambuyo pa chithandizo cha kutentha kotsiriza pali kuwala komaliza (kujambula kozizira) Ndi ndondomeko yoyenera yotsatira, chubu chikhoza kukhala chozizira (mwachitsanzo, kupindika, kukulitsidwa) mkati mwa malire ena.
Annealed	GBK	Pambuyo pomaliza kupanga kuzizira, machubu amalowetsedwa mumlengalenga wowongolera kapena pansi pa vacuum.
Zokhazikika	NBK	Machubu amatsekedwa pamwamba pa malo osinthika apamwamba mumlengalenga woyendetsedwa kapena pansi pa vacuum.
