Cold-rolled, cold-drawn or cold-rolled and cold drawn combination of cold working process for the production of paipa afifi o meafaigaluega tuufaatasia.O le paipa uelo fa'a'avevela vevela po'o le loloto o fa'agaau fa'apa'au.

Faʻavae i luga o le gaosiga o meatotino o le uʻamea, le tele o paipa, manaʻoga lelei faʻapea foʻi ma tupe teufaafaigaluega ma faʻamanuiaga e filifili ai metotia faʻagasologa eseese ma faʻagasologa fesoasoani tutusa.

O le laasaga autu o le tuʻu faʻafefe malulu o:

(1) o le paipa sapalai o le suauu, o mea paipa o loʻo faʻaaogaina mo faʻamaʻi faʻamaeʻaina vevela poʻo semi-tube, oomi faagaau ma paipa uelo.

(2) saunia mea paipa, e aofia ai le siakiina, faʻapipiʻiina, fufuluina o le acid, faʻamamaina, fufuluina, ma faʻagogo, ufiufi lubricants

(3) mālūlū (taai-malulu po'o le tosoina o le malulu)

(4) maeʻa maeʻa faʻamaeʻaina e aofia ai togafitiga vevela, faʻasaʻo, faʻataʻitaʻiga, tipi le ulu ma le siʻusiʻu, siaki (suʻesuʻeina ma suʻega o mea faʻapitoa), suʻega hydrostatic, suauʻu, afifiina, fale teu oloa ma isi.E eseese mea e fa'auma ai oloa e eseese.

Fa'aaliga malili paipa mill gaosiga o lo'o fa'amoemoeina mai le paipa i totonu o le fa'agaoioiga i oloa mae'a e masani lava pe a mae'a le tele o le malulu ma maua ai le fa'ama'a'aina o galuega, o lea o le faagasologa atoa o le gaosiga o la'asaga sauniuni e ala i le tele o le deformation faagasologa ma le tuufaatasiga, ma ei ai uiga o le cyclical ma o lea e sili atu. laʻasaga , taamilosaga umi o gaosiga, faʻaaogaina uʻamea tele, e maualalo le lelei o le gaosiga, e masani lava e le o se gaosiga tele.

Configured i chiller malulu tosoina ma malulu-taʻavale mill e conducive e taʻalo o latou tulaga lelei, aemaise lava mo le gaosiga o le uamea stainless, paipa uʻamea uʻamea maualuga ma le paipa uʻamea faigata deformed sili atu talafeagai ma talafeagai.O le masini tusi ata e tasi ma le tele o masini toso sa'o ma le fa'a'au'au (va'ai le fa'a'au'au).A o se tasi malulu toso paipa umi o le 50m, o ni nai selau mita i luga reel extubation.Tone masini tusi ata la'ititi 30kN, e o'o atu ile 7000kN.O lo'o i ai le lua fa'amalo ta'avale malulu ta'avale vili malulu ma le malulu ta'avale u'amea lua ituaiga o ta'avale tele.
