Irin pipe

Nitori ti awọn oniwe-ẹrọ ilana ti o yatọ si, o ti wa ni pin si gbona yiyi (extruded) seamless, irin tube ati ki o tutu fa (yiyi) seamless irin tube meji iru.

A.Akopọ ti sisan ilana

Yiyi gbigbona (irin tube ti a ko ni itọlẹ) : yika tube billet → alapapo → perforation → sẹsẹ agbelebu mẹta-yiyi, yiyi lilọsiwaju tabi extrusion → yiyọ tube → iwọn (tabi idinku) → itutu → tube òfo → taara → idanwo titẹ omi (tabi wiwa abawọn) → isamisi → ipamọ.

Yiya tutu (yiyi) tube irin ti ko ni alaini: yika tube billet → alapapo → perforation → akọle → annealing → pickling → oiling (plating bàbà) → olona-kọja tutu iyaworan (yiyi tutu) → tube òfo → itọju ooru → taara → idanwo titẹ omi (wiwa abawọn) → isamisi → ibi ipamọ.
