ERW o se paipa uʻamea uʻamea eletise-tetee, ua vaevaeina Resistance uʻamea paipa uamea i le fesuiaiga o paipa uʻamea uʻamea ma DC uʻamea paipa uamea i ni faiga se lua.

O le faʻaogaina o le AC e tusa ai ma laina eseese o loʻo vaevaeina i le faʻafefe maualalo, AFAI faʻafefe, faʻapipiʻiina o le ultra-IF ma le faʻafefe maualuga. E masani ona faʻaaogaina le uʻamea maualuga mo le gaosiga o paipa uʻamea manifinifi puipui poʻo paipa uʻamea mafiafia puipui, uʻamea maualuga i le faʻafesoʻotaʻi ma le faʻapipiʻiina. DC uelo e masani ona faʻaaogaina mo paipa uʻamea laiti-diameter. O lea la, i le tulaga o le atoatoa, maualuga-auso paipa uelo aofia i totonu o le paipa ERW o se faiga uelo maualuga e maua ai paipa ERW. ERW Longitudinal alualu i luma oloa faatinoga i le fanua o le suauu ma kesi teuina ma felauaiga, tulaga lelei taitaiga, sili atu le tamaoaiga paipa uʻamea.

O paipa u'amea SAW e puupuu i le Submerged Arc Welding Steel Pipe, lea o se fa'aogaina o le fa'aogaina o le soldering arc e gaosia ai uamea, o le faagasologa e maua ai le maualuga o le taimi nei, o le flux layer e puipuia ai le vave leiloa o le vevela, ma fa'atumauina i le itulagi uelo. O lo'o fa'auluina arc uelo o le tulaga maualuga, maualuga le gaosiga lelei, arc ma le asu o ni nai uiga o le arc fa'afefeteina paipa o lo'o fa'aaogaina lautele i totonu o va'a mamafa, gaosiga o paipa, fa'alava, vai maualalo mamafa, galuega u'amea. O oloa autu o le SAW uamea paipa LSAW uamea paipa, Longitudinally Submerged Arc U'umea uamea paipa LSAW u'amea paipa, o le fa'aogaina o le fa'aluulu arc uelo gaosiga o le sa'o seam paipa u'amea.

Eseesega i le vaerwmavaaipaipa uamea

E pei o le ERW paipa uamea ma SAW paipa uamea i totonu o le paipa i le taimi o le faia, uelo ma faagasologa e ese, ina ia lua ituaiga o paipa uamea i le faatinoga o loo i ai ni eseesega.

(1) ERW lelei paipa paipa luga e sili atu i le lilivau arc uelo paipa, ERW uamea paipa luga e lamolemole, lamolemole, matagofie, SAW paipa uamea i totonu ma fafo faʻamalosia faʻamalosi.

(2) ERW uamea paipa uelo ituaiga faaletonu e itiiti ifo nai lo le vaai uamea paipa. Saw paipa uʻamea ma solvent teuina, sili atu ituaiga o faaletonu, i le faaopoopo atu i le tele o faaletonu, o loo i ai uaea-laina mailei. ERW uamea paipa weld faaletonu na o le uaea-laina ma saʻo welds, le faagasologa o asiasiga faigofie e mulimuli ai, ma le faaletonu i le vaaiga aupito maualuga i, le taimi lava le leai o implicit, ultrasonic atagia le malosi, faigofie ona iloa.

(3) ERW paipa uʻamea e fesoʻotaʻi ma vaʻai paipa uʻamea i le faʻasologa o faʻafitauli mamafa e maualalo. Talu mai le deformation paipa ERW i le faagasologa deformation sili atu atoatoa, sosoo sizing mafolafola oval, elliptical suiga tūsaʻo ma le ua, faia ERW paipa totoe popole avea laiti. Fa'ata'ita'iga fa'aletino na fa'aalia ai o fa'amatalaga tutusa, o le mea lava e tasi ERW paipa ina ua uma le incision i luga o le axis, o le axial ma transverse incisions la'ititi le displacement nai lo le paipa fa'afefeteina arc uelo.

(4) ERW Pipe le faatinoga atoa o le mea lava e tasi, pe a oo ina faaletonu le paipa, uamea solo faamasinoga, faatagaina uelo. SAW uamea paipa faatagaina, ma paipa uelo faatinoga ma le faatinoga atoa e le ogatasi, uelo nofoaga faigofie i faamamafa corrosion ta'e. O fa'ata'ita'iga fa'ata'ita'iga o lo'o fa'aalia ai le fa'amamafaina o le vaivai o le su'ega ERW paipa fa'ato'a fa'afefeteina le umi o paipa i lo le ola.
