Pipe pipe fun eto (GB / T8162-2008) ni a lo fun eto gbogbogbo ati ọna ẹrọ ti pipe pipe.

Irin alagbara, irin pipe paipu fun eto (GB/T14975-2002) jẹ yiyi gbona (extruded, faagun) ati tutu-fa (yiyi) paipu ti ko ni oju ti a ṣe ti irin alagbara ti a lo ninu kemikali, epo, aṣọ, iṣoogun, ounjẹ, ẹrọ ati miiran ise, ipata-sooro oniho ati igbekale awọn ẹya ara ati irinše.

GB/T8162-2008 (piipu ti ko ni ailopin fun eto) ni a lo fun ipilẹ gbogbogbo ati ọna ẹrọ.Awọn ohun elo aṣoju (brand): erogba irin 20, 45 irin, Q235, irin alloy Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo , 42CrMo ati bẹbẹ lọ.

Irin pipe

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

A.Akopọ ti sisan ilana

Yiyi gbigbona (irin tube ti 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 abawọn) wiwa) → isamisi → ibi ipamọ.

Iyaworan tutu (yiyi) tube irin ti ko ni alaini: yika tube billet → alapapo → perforation → akọle → annealing → pickling → oiling (fifun idẹ) → iyaworan otutu-ọpọlọpọ (yiyi tutu) → tube òfo → itọju ooru → taara → idanwo titẹ omi (iwari abawọn) → isamisi → ibi ipamọ.
