Spiral Welded Carbon Steel Umuyoboro Wamazi
1. Sobanukirwa n'umuyoboro w'icyuma wa karuboni weld:
Umuyoboro wogosha wa karuboneikozwe mu buryo bwuzuye kandi isudira mu byuma.Uburyo budasanzwe bwo gukora butuma iyi miyoboro ikomera kandi ikaramba, ikabasha kwihanganira umuvuduko mwinshi wimbere ninyuma.Ubushobozi bwo kurwanya ruswa no guhindura ibintu nabyo bituma bukoreshwa muburyo butandukanye, harimo imiyoboro y'amazi hamwe no gusudira ibyuma.

2. Umuyoboro w'amazi:
Muri gahunda yo gukwirakwiza amazi, gutanga amazi meza kandi meza ni ngombwa.Umuyoboro w’icyuma wa karuboni washyizwe ahagaragara wagaragaje ko ari amahitamo yizewe ku miyoboro y’amazi bitewe n’imiterere irwanya ruswa.Ubuso bworoshye bwiyi miyoboro bugabanya guterana amagambo, bigatuma amazi ahora atemba kandi bikagabanya imivurungano.Byongeye kandi, imbaraga zisanzwe hamwe nigihe kirekire byemeza ko birinda kumeneka, kumeneka, no kunanirwa kwubaka, bigatuma amazi akomeza, yizewe.
3. Gusudira ibyuma:
Inganda zo gusudira zishingiye cyane cyane ku cyuma cya karuboni cyuma gikoreshwa muburyo butandukanye.Imbaraga zidasanzwe nubworoherane bwiyi miyoboro bituma biba byiza kubudozi bwo gusudira ibyuma.Haba kubaka ibigega binini byo kubikamo, imiyoboro yo gutwara peteroli na gaze, cyangwa ibice byubatswe mu nganda, imiyoboro ya karuboni izunguruka ifite uruhare runini.Uburinganire bwingingo zisudira butuma ubwizerwe numutekano byimiterere, bigabanya gukenera kubungabungwa cyangwa gusanwa kenshi.
4. Inyungu nibyiza:
4Kuramba kwabo no kurwanya ruswa bituma ubuzima bumara igihe kirekire, bityo bikagabanya amafaranga yo gusimburwa no kubungabunga.
4.2 Byoroshye kwishyiriraho: Tekinoroji yo gusudira izunguruka ikoreshwa mubikorwa byo gukora irashobora gutanga imiyoboro miremire kandi ikomeza, bikagabanya gukenera ingingo nyinshi.Igishushanyo cyoroheje cyoroshya inzira yo kwishyiriraho, gitwara igihe n'imbaraga.
4.3 Guhinduranya: Umuyoboro wogosha wicyuma cya karubone uraboneka muburyo butandukanye bwa diametre nubunini, ubemerera guhuza nibikorwa bitandukanye.Birashobora guhindurwa kugirango byuzuze ibisabwa byumushinga, bihuza n'amazi atandukanye, imikazo n'ubushyuhe.
4.4 Kurengera ibidukikije: Ibyuma bya karubone ni ibikoresho bisubirwamo bigira uruhare mu kubungabunga ibidukikije.Imiyoboro y'icyuma ya karuboni isudira irashobora gukoreshwa kandi ikongera gukoreshwa, kugabanya imyanda no kurinda umutungo kamere.
Mu gusoza:
Ubushobozi nibyiza bya spiral weld wapine ibyuma bya karubone mumiyoboro yamazi nagusudira ibyumantishobora gusuzugurwa.Ihererekanyabubasha ryizewe ryamazi namazi yinganda zishingiye cyane kubiramba, kurwanya ruswa no koroshya kwishyiriraho.Mu gihe hakenewe ibikorwa remezo bikomeye kandi bidahenze bikomeje kwiyongera, imiyoboro y’icyuma ya karuboni izunguruka izakomeza kuba ikintu cy’ingenzi mu gutuma imikorere y’amazi n’imikorere y’inganda ku isi hose.
