Gigun welded pipe ni ilana iṣelọpọ ti o rọrun, ṣiṣe iṣelọpọ giga, idiyele kekere ati idagbasoke iyara.Agbara ajija welded oniho ni gbogbo ti o ga ju ti o ni gígùn pelu welded oniho.Òfo òfo ni a le lo lati ṣe awọn paipu welded pẹlu awọn iwọn ila opin ti o tobi ju, ati billet kan ti o ni iwọn kanna tun le ṣe awọn paipu welded pẹlu oriṣiriṣi awọn iwọn ila opin paipu.Ṣugbọn ni akawe pẹlu paipu okun gigun ti gigun kanna, gigun weld pọ si nipasẹ 30-100%, ati iyara iṣelọpọ jẹ kekere.
Iwọn ila opin nla tabi awọn paipu welded nipọn ni gbogbogbo ni a ṣe taara lati awọn òfo irin, lakoko ti awọn paipu welded kekere ati awọn paipu welded ogiri nikan nilo lati wa ni welded taara nipasẹ awọn ila irin.Lẹhinna lẹhin didan ti o rọrun, iyaworan jẹ itanran.
Àfikún: Paipu welded ti wa ni welded pẹlu rinhoho irin, ki o jẹ ko ga bi a seamless paipu.
Awọn ọja ni lilo pupọ ni imọ-ẹrọ ipese omi, ile-iṣẹ petrochemical, ile-iṣẹ kemikali, ile-iṣẹ agbara, irigeson ogbin, ati ikole ilu.O jẹ ọkan ninu awọn ọja bọtini 20 ti o dagbasoke ni orilẹ-ede mi.
Ti a lo fun gbigbe omi: ipese omi ati idominugere.Ti a lo fun gbigbe gaasi: gaasi eedu, nya si, gaasi epo olomi.
Fun awọn idi eleto: bi piling pipes ati awọn afara;paipu fun awọn ibi iduro, awọn ọna, ati awọn ẹya ile.
