Lelei ma le Malosi o Paipa Fa'apipi'i Fa'alava i le Fa'apipi'iina o Paipa Fa'aautomatika
O mea mata e faʻaaogaina e gaosia aiPaipa SAWHe aofia ai uaea u'amea, uaea uelo ma le flux. O nei meafaitino e ui atu i su'esu'ega fa'aletino ma vaila'au fa'apitoa a'o le'i fa'aaogaina i le faagasologa o le gaosiga. O lenei mea e fa'amautinoa ai e na'o meafaitino sili ona lelei e fa'aaogaina, ma i'u ai i se oloa mae'a e maualuga lona tulaga lelei.

E amata le faagasologa o le gaosiga i le fa'apipi'iina o fasi u'amea mai le pito i le pito e fa'aaoga ai le mono- po'o le twin-wire submerged arc welding. O lenei faagasologa e fa'amautinoa ai se feso'ota'iga lelei i le va o le ulu ma le si'usi'u, ma fa'aleleia atili ai le tulaga mautu o le paipa. A mae'a lena, ona milo lea o le fasi u'amea i se foliga o se paipa. Ina ia fa'amalosia atili ai le paipa, e fa'aaogaina le automatic submerged arc welding mo le toe fa'aleleia o le welding. O lenei faagasologa o le welding e fa'aopoopoina ai se vaega fa'aopoopo o le tumau, e mafai ai e le paipa ona tatalia tulaga faigata o le siosiomaga.
O paipa SAWH ua mamanuina ina ia tausisia aiaigaEN10219tulaga faatonuina, ma fa'amautinoa ai lo latou fetaui ma le tele o fa'aoga fa'apisinisi. E maua i mafiafia o puipui e amata mai le 6mm i le 25.4mm, o nei paipa e fetaui lelei mo le tele o galuega faatino. Pe o le atina'eina o atina'e tetele, felauaiga o le suau'u ma le kesi po'o galuega faufale, e tu'uina atu e le SAWH Pipes ni fofo fa'atuatuaina ma lelei.
O le Cangzhou Spiral Steel Pipes Group Co., Ltd. o se kamupani gaosi oloa i totonu o le atunu'u e ta'imua i paipa u'amea fa'ata'amilomilo. E 13 laina fa'apitoa a le kamupani mo paipa u'amea fa'ata'amilomilo ma laina gaosiga e 4 e tete'e atu ai i le 'ele ma le fa'amafanafana, fa'atasi ai ma le malosi tele o le gaosiga. E fa'apitoa le kamupani i le gaosiga o paipa u'amea fa'ata'amilomilo ua fa'apipi'iina i le arc ma le lautele mai le Φ219mm i le Φ3500mm. O nei paipa e maua i le tele o mafiafia o puipui, e mafai ai e tagata fa'atau ona filifili le fa'amatalaga e sili ona fetaui ma a latou fa'aoga.
O le tautinoga a le kamupani i le lelei e atagia mai i faiga fa'atonutonu lelei i le faagasologa atoa o le gaosiga. O paipa ta'itasi e siakiina mae'ae'a ina ia mautinoa e ausia tulaga fa'atonuina o le alamanuia ma mana'oga o tagata fa'atau. E le gata i lea, o lo'o i ai i le kamupani se 'au fa'apitoa o tagata tomai fa'apitoa o lo'o fa'aleleia pea metotia o le gaosiga ma fa'alauiloa tekinolosi fou e fa'afetaui ai mana'oga fesuisuia'i o le alamanuia.
I se aotelega, o paipa SAWH e gaosia e le Cangzhou Spiral Steel Pipes Group Co., Ltd. e faʻatuatuaina, tumau ma talafeagai mo le tele o faʻaoga faʻapisinisi. I le mulimulitaʻi i faiga faʻatonutonu lelei ma le tausisia o tulaga faʻavaomalo, o nei paipa e ofoina atu le maualuga o le faʻatinoga ma le umi o le ola tautua. A oʻo mai i paipa uʻamea, faʻamolemole ia talitonu i le lelei tele ma le taua tele o le Cangzhou Spiral Steel Pipes Group Co., Ltd.
