O paipa uamea o se fasi uamea uumi gaogao, lea e masani ona faaaoga e avea o se paipa mo felauaiga vai, e pei o le suauu, kesi faalenatura, vai, kesi, ausa, ma isi. I le faaopoopo atu, e mama i le mamafa pe a punou ma torsional malosi e tutusa, o lea e faʻaaogaina lautele Faʻaaogaina i le gaosiga o vaega masini ma fausaga inisinia.E masani foi ona faʻaaogaina e gaosia ai auupega masani, paelo, atigi, ma isi. e 6 mita le umi.O le gaosiga o le gaosiga o paipa uʻamea e faigofie, o le gaosiga e maualuga, e tele ituaiga ma faʻamatalaga, ma o le faʻafaigaluegaina o meafaigaluega e laʻititi, ae o le malosi lautele e maualalo ifo nai lo le paipa uʻamea.
Fa'avasegaina o paipa uamea
Fa'avasegaina ile faiga ole gaosiga
(1) E tusa ai ma le faagasologa - arc uelo paipa, tetee uelo paipa (maualuga taimi, maualalo taimi), kesi uelo paipa, ogaumu uelo paipa
(2) E tusa ai ma le uelo - sa'o su'isu'i paipa uelo, spiral uelo paipa
Fa'avasegaina i foliga o vaega
(1) O paipa u'amea fa'alava faigofie—paipa u'amea lapotopoto, paipa u'amea faatafafa, paipa u'amea lapotopoto, paipa u'amea tafatolu, paipa u'amea hexagonal, paipa u'amea rhombus, paipa u'amea fa'afafa, li'o u'amea semicircular, isi.
(2) Pa'u u'amea lavelave fa'a'ese'ese - paipa u'amea le tutusa, paipa u'amea lima-petal, paipa u'amea lua, paipa u'amea fa'alua, paipa u'amea fa'ameli, paipa u'amea conical, paipa u'amea, pusa uamea paipa, ma isi.
E tusa ai ma le mafiafia o le puipui, e mafai ona vaevaeina i: paipa uʻamea manifinifi puipui ma paipa uʻamea mafiafia;
E tusa ai ma foliga o le pito, e mafai ona vaevaeina i: paipa uelo lapotopoto ma faʻapitoa-foliga (sikuea, mafolafola, ma isi) paipa uelo;
Fa'avasegaga ile fa'amoemoe
O paipa uelo lautele, paipa u'amea, paipa uelo okesene, pusa uaea, paipa u'amea metric, paipa paie, paipa paipa loloto, paipa ta'avale, paipa transformer, paipa pa'u manifinifi fa'aeletise, fa'amea fa'ameamea. paipa ma paipa fa'afefeteina.
O le faamoemoega autu
E masani ona faʻaaogaina i le faʻainisinia o le suavai, pisinisi petrochemical, fale kemisi, eletise eletise eletise, faʻatoʻaga faʻatoʻaga, ma le fausiaina o taulaga.O se tasi lea o oloa autu e luasefulu ua atiae e lo tatou atunuu.
Fa'aaogaina mo felauaiga vai: vai ma alavai.Mo felauaiga kesi: kesi, ausa, kesi suau'u liquefied.
Mo faʻamoemoega faʻavae: pei o paipa faʻaputu, pei o alalaupapa;paipa mo uafu, auala, fausaga fale, ma isi.
Ua vaevaeina paipa uʻamea uʻamea i uʻamea ma le uʻamea e tusa ai ma le togafitiga luga o le paipa.E mafai ona vaevaeina paipa uʻamea uʻamea i ni ituaiga se lua pe a latou tuua le fale gaosimea: o le tasi e filo i le pito o le paipa, ma le isi e le o filo i le pito o le paipa.Mo paipa uʻamea uʻamea ma filo i pito paipa, o le umi o paipa taʻitasi e 4-9m, ma mo paipa uʻamea uʻamea e aunoa ma ni filo, o le umi o paipa taʻitasi e 4-12m.
O paipa uʻamea uʻamea e vaevaeina i paipa uʻamea manifinifi puipui, paipa uʻamea mafiafia ma paipa uʻamea masani e tusa ai ma le mafiafia o le puipui o le paipa.O paipa uamea masani e sili ona faʻaaogaina i paipa faʻagasologa, ma o latou faʻataʻitaʻiga o le 2.0MPa.Ole mamafa ole su'ega ole paipa uamea mafiafia ole 3.0MPa.
E tele auala fesoʻotaʻiga mo paipa uʻamea uʻamea, e aofia ai fesoʻotaʻiga filo, fesoʻotaʻiga flange ma uʻamea.O le fesoʻotaʻiga flange e vaevaeina i le fesoʻotaʻiga flange filo ma le fesoʻotaʻiga flange, ma o le auala uʻamea e vaevaeina i le kesi ma le arc welding.
E masani ona fa'aogaina paipa u'amea fa'amatalaga fa'avasegaga: ta'oto fa'atatau 6 ~ 150mm
O paipa uʻamea uʻamea e mafai ona vaevaeina i ni vaega se tolu e tusa ai ma le faiga o le faiga:
1. Fa'aeletise tete'e paipa u'amea
Pipa u'amea u'amea eletise tete'e, igoa Igilisi ERW (Electric resistance welded Pipe), ituaiga uelo e su'i sa'o.O le uelo tetee e faʻaaogaina le auala faʻamalosi e aunoa ma le faʻatumu uʻamea.E leai se fa'atumuina o isi vaega i le su'iga uelo.O le a'afiaga o le pa'u ma le fa'alatalata o le taimi nei e fa'avevela vave ai le pito o le ipu i le vevela o le uelo, ma o le fa'atupuina e faia e ala i le oomiina o le ta'avale extrusion.uelo i'usau.
E mafai ona vaevaeina paipa u'amea tetee tetee i ni vaega se lua: uelo fa'afefete maualuga HFW (paipa uelo maualuga) ma le uelo fa'afefe maualalo LFW (Low frequency welding).
O paipa uamea ERW e masani ona faʻaaogaina e felauaiga ausa ma mea vai e pei o le suauʻu ma le kesi masani, ma e mafai ona ausia manaoga eseese o le maualuga ma le maualalo o le mamafa.I le taimi nei, latou te nofoia se tulaga taua i le tulaga o paipa felauaiga i le lalolagi.
2. Pipa u'amea fa'ameamea
Pipa u'amea fa'apipi'i, igoa fa'aPeretania SSAW (Spiral submerged-arc uelo paipa), fa'aigoa fa'ailoga o le su'isu'i.O le auala o le uelo arc ua faʻafefeteina o loʻo faʻaaogaina, ma o totonu ma fafo e faʻapipiʻi faʻalua.O le ueloina o le arc (e aofia ai le faʻafefe o le arc ma le electroslag surfaces, ma isi) o se auala taua tele, lea e iai le lelei o le lelei o le uʻamea, maualuga le gaosiga o le uelo, leai se moli arc ma sina asu ma pefu.
O le paipa faʻapipiʻiina o loʻo i ai le lautele tele, lea e mafai ona oʻo atu i le sili atu i le 3000mm, ma e sili atu ona talafeagai mo felauaiga paipa tele-diameter ma fausaga fale.
Tolu, su'isu'i sa'o paipa u'amea
Longitudinally Submerged Arc Welded Pipe, o le igoa Igilisi o le LSAW (Longitudinally Submerged Arc Welded Pipe), ma o le ituaiga uelo o le su'i sa'o.O loʻo faʻaaogaina foʻi le auala o le faʻafefe o le arc, ma faʻapipiʻi faʻalua i totonu ma fafo.O le mafiafia o le puipui o le paipa u'amea su'isu'i sa'o e fai si tele, ma o lona fa'aogaina e tutusa ma le paipa u'amea fa'ameamea.
E tusa ai ma faiga eseese faiga, e mafai ona vaevaeina paipa uʻamea suʻisuʻi saʻo i ni vaega se lua: UOE (Uing ma Oing faia paipa) ma JCOE (J-ing, C-ing ma O-ing paipa).UOE faiga auala (U fau, O faia, E lautele faalauteleina), JCOE faiga auala (uʻamea ipu ua oomi i foliga J, ona oomi i C foliga ma O foliga i le faasologa, ona faalauteleina).
E tatau ona maitauina o le faagasologa o le uelo faʻafefe (SAW) o se ituaiga o uʻamea eletise eletise (EFW Electric Fusion Welded Pipe), o le tuʻufaʻatasia lea o uʻamea e ala i le faʻamafanafanaina o le uamea i le va o le tasi poʻo le tele o eletise faʻaaogaina ma le mea faigaluega.O se tasi o faiga e faʻafefeteina atoa ai e le arc le uʻamea ma le mea e faʻatumu ai mea e aunoa ma le mamafa, ma o le vaega faʻatumu e sau mai le eletise.
