1. Faʻavasegaina i le gaosiga metotia
(1) Seamless paipa - paipa vevela faʻasolosolo, malulu paipa paipa, malulu paipa paipa, extrusion paipa, paipa jacking (2) uelo paipa (a) E tusa ai ma le gaioiga - arc paipa maopoopo, tetee paipa maopoopo (maualuga taimi, maualalo taimi) , paipa ueloina o le kesi, paipa uelo ogaumu (b) e tusa ai ma le laina uelo - paipa ueloina saʻo, paipa ueloina uila.

A. vevela faʻasolosolo uʻamea paipa uʻamea: vevela faʻasolosolo e faʻafeagai ma le malulu faʻasolosolo, lea o loʻo faʻasolosolo i lalo o le recrystallization vevela. Vevela faʻasolosolo o loʻo faʻataʻamilomilo luga o le recrystallization vevela.
Adavantage: mafai ona faʻaleagaina le ingot lafo faʻalapotopotoga, faʻamamaina uamea saito ma aveʻese le faʻaletonu o le microstructure, lea e faia uamea vaega e latalata-grained, masini faʻaleleia ua faʻaleleia. O lenei faʻaleleia e tele lava ona atagia mai i le taʻavale taʻavale, ina ia o le uʻamea e leai umi isotropic i se tasi itu, fula, taʻetaʻei ma le toʻafilemu faia i le taimi o le sasaʻaina mafai foi ona uʻameaina i lalo o le maualuga vevela ma le mamafa.

B. malulu faʻaseʻe uʻamea paipa: Malulu-faʻasolosolo seamless paipa (GB3639-2000) o loʻo faʻaaogaina mo masini fausaga ma vaʻalele masini ma maualuga dimensional sao ma laulau
Malulu na tosoina pe malulu na faʻasolosolo faʻasologa lelei uʻamea paipa ma lelei luga maeʻa.
Lelei: e mafai ona faʻaleagaina le faʻavaeina o uʻamea ingot, faʻamamaina le saito o le sila, ma aveʻese le faʻaletonu o microstructure, ina ia le microstructure o uʻamea mafai ona compactness ma masini meatotino mafai ona faʻaleleia. O lenei faʻaleleia e tele lava ona atagia mai i le taʻavale taʻavale , ina ia le uʻamea ua le toe isotropic i sina itu; Pula, taʻetaʻei ma looseness fausiaina i le taimi o le sasaʻaina mafai foi ona uʻameaina i lalo o le maualuga vevela ma le mamafa.

C. extrusion paipa: O le faʻamafanaina o le paipa avanoa ua tuu i totonu o se tapunia ogāumu ogāumu, ma o le faʻapipiʻiina toʻotoʻo faʻagaeʻeina ma le faʻasologa tootoo e faia le vaega extrusion alu ese mai le laiti oti pu. Lenei metotia mafai gaosia paipa uʻamea ma laititi lapoa.

Adavantage: Faatasi ai ma le lelei uamea compactness ma toniga fausaga, e talafeagai mo le gaosiga o toeitiiti uma ituaiga o uʻamea paipa, aemaise lava mo le gaosiaina o maualuga-uʻamea filogia, leai-deformable uamea ma ituaiga uma o faʻapitoa-foliga koluse-vaega paipa. Ona o lona lelei faʻatinoina, vevela extruded uʻamea paipa oloa i ai le mafai ona suia talosaga lumanaʻi i le maualuluga ma autu matata o le atunuʻu tamaoaiga e pei o militeri pisinisi, malosiaga faaniukilia, vevela mana, vaʻalele, maina, suauʻu lelei ma petrochemical alamanuia. Taumafaiga e suʻesuʻe ma atiaʻe maualuga gaioiga, maualuga tekonolosi mataupu ma maualuga faʻaopoopo taua o vevela extruded oloa paipa uʻamea, e faʻalauteleina ai le atinaʻe o le atunuʻu maualuga-iuga paipa uʻamea tekonolosi ma faʻamalosia le atoatoa tamaoaiga malosiaga e matua loloto lona taua

3. Faʻavasegaina ile vaega foliga
(1) Faigofie paipa uʻamea - faʻataʻamilo paipa uʻamea, sikuea paipa uʻamea, elliptic paipa uʻamea, tafatolu uʻamea paipa, hexagonal uʻamea paipa, taimana paipa uʻamea, octagonal paipa uʻamea, semi-liʻo uʻamea paipa, ma isi (2) laʻasaga faigata uʻamea paipa - Tubes uʻamea le tutusa hexagonal, paipa uʻamea foliga e lima lopa.
Paipa, faʻalua paipa uʻamea faʻapipiʻi, faʻalua paipa uʻamea faʻapipiʻi, meleni fatu uʻamea paipa, paipa uʻamea faʻapipiʻi, paipa uʻamea faʻapipiʻi, paʻu uʻamea faʻapipiʻi, isi.
4. Faʻavasegaina ile puipui mafiafia - paipa uʻamea pa manifinifi, paipa uʻamea pa puipui mafiafia.
5. Faʻavasegaina e ala i le faʻaaogaina - paipa, meafaigaluega vevela, fale gaosi masini, suauʻu, eliina o eleele maʻa, koneteina, vailaʻau vailaʻau, faʻamoemoe faʻapitoa, isi.
