Umuyoboro w'ibyuma bya karuboni byasutswe mu buryo bw'umwuka wo gufunga imiyoboro y'amazi

Ibisobanuro bigufi:

Mu bikorwa remezo binini, imikorere myiza y’amazi n’inganda ishingiye cyane ku kuramba no gukora neza kw’imiyoboro. Mu moko atandukanye y’imiyoboro ikoreshwa, imiyoboro y’icyuma gikozwe mu buryo bwa spiral ikwiye kwitabwaho kubera imbaraga zayo zidasanzwe n’uburyo butandukanye bwo gukora. Hasi hatangira ibisobanuro by’akamaro n’ibyiza by’imiyoboro y’icyuma gikozwe mu buryo bwa spiral ikoreshwa muimiyoboro y'amazi no gusudira imiyoboro y'icyuma.

Ohereza imeri kuri twe

Ibisobanuro birambuye ku gicuruzwa

1. Sobanukirwa umuyoboro w'icyuma cya karuboni gikozwe mu buryo bwa spiral welded:

Umuyoboro w'icyuma cya karuboni ukozwe mu buryo bw'umwukaIkorwa mu buryo bwo kuzunguruka kandi ikanasukwa mu byuma bizunguruka. Uburyo bwihariye bwo kuyikora butuma iyi miyoboro ikomera kandi iramba, ikabasha kwihanganira igitutu kinini cy’imbere n’inyuma. Ubushobozi bwo kurwanya ingese no kwangirika butuma ikoreshwa mu buryo butandukanye, harimo imiyoboro y’amazi n’imiyoboro y’icyuma.

2. Imiyoboro y'amazi:

Mu buryo bwo gukwirakwiza amazi, gutanga amazi meza mu buryo bwizewe kandi bunoze ni ingenzi cyane. Umuyoboro w'icyuma cya karuboni wasutswe mu buryo bw'umwuka wagaragaye ko ari amahitamo yizewe ku miyoboro y'amazi bitewe n'ubushobozi bwayo bwo kwirinda ingese. Ubuso bworoshye bw'iyi miyoboro bugabanya gukururana, bigatuma amazi ahora atemba kandi bukagabanya umuvuduko. Byongeye kandi, imbaraga n'ubudahangarwa bw'amazi bitanga uburinzi ku mazi ava, kuvunika no kwangirika kw'inyubako, bigatuma amazi akomeza kuboneka kandi yizewe.

3. Gusudira imiyoboro y'icyuma:

Inganda zikora ubudozi zishingiye cyane ku miyoboro y'icyuma gikozwe mu buryo bwa spiral welded steel mu bikorwa bitandukanye. Ingufu zidasanzwe n'uburyo bworoshye bw'iyi miyoboro bituma iba nziza mu gusudira imiyoboro y'icyuma. Byaba kubaka ibigega binini byo kubikamo, imiyoboro yo gutwara peteroli na gaze, cyangwa ibice by'imiterere mu nganda, imiyoboro y'icyuma gikozwe mu buryo bwa spiral welded steel ifite uruhare runini. Uburyo bumwe bw'imiyoboro ikozwe mu buryo bwa spiral butuma inyubako ihora yizewe kandi itekanye, bigagabanya gukenera kuyisana cyangwa kuyisana kenshi.

4. Ibyiza n'inyungu:

4.1 Igisubizo gihendutse: Umuyoboro w'icyuma cya karuboni ukozwe mu buryo bwa "spiral welded steel" utanga igisubizo gihendutse cyo gusudira imiyoboro y'amazi n'imiyoboro y'icyuma. Kuramba kwawo no kudatwarwa n'ingufu bitanga igihe kirekire cyo gukora, bityo bikagabanya ikiguzi cyo gusimbuza no kubungabunga.

4.2 Byoroshye gushyiraho: Ikoranabuhanga ryo gusudira rikoreshwa mu gukora rishobora gukora imiyoboro miremire kandi ihoraho, bigabanyiriza gukenera guhuza ibintu kenshi. Iyi miterere yoroshye yoroshya uburyo bwo kuyishyiraho, ikagabanya igihe n'imbaraga.

4.3 Uburyo bwo gukora ibintu bitandukanye: Imiyoboro y'icyuma cya karuboni ikoreshwa mu buryo bworoshye iboneka mu bugari n'ubugari butandukanye, bigatuma ikoreshwa mu buryo butandukanye. Ishobora guhindurwa kugira ngo ihuze n'ibisabwa by'umushinga, ihuzwe n'amazi atandukanye, igitutu n'ubushyuhe butandukanye.

4.4 Kurengera ibidukikije: Ibyuma bya karuboni ni ibikoresho bishobora kongera gukoreshwa bifasha mu kubungabunga ibidukikije. Imiyoboro ya karuboni ikoreshwa mu buryo bworoshye ishobora kongera gukoreshwa no kongera gukoreshwa, bigagabanya imyanda kandi bikarinda umutungo kamere.

Mu gusoza:

Ubushobozi n'ibyiza by'imiyoboro ya karuboni ikoze mu cyuma gitemba amazi n'amazigusudira imiyoboro y'icyumaNtibishobora gusuzugurwa. Uburyo bwiza kandi bwizewe bwo kohereza amazi n'amazi yo mu nganda bushingiye cyane ku kuramba kwabyo, kurwanya ingese no koroshya gushyiraho. Mu gihe hakomeje kwiyongera ibikorwa remezo bikomeye kandi bihendutse, imiyoboro ya karuboni ikoreshwa mu byuma bizunguruka izakomeza kuba ingenzi mu gutuma sisitemu z'amazi n'inganda zikora neza hirya no hino ku isi.

Ibanjirije iyi: Akamaro k'Umuyoboro w'Ingufu Uzibye mu Muyoboro wa API 5L Line Pipe Sudira Umuyoboro wa Karuboni

Ibikurikira: Umuyoboro wa A252 wo mu cyiciro cya 1 w'icyuma mu muyoboro wa Helical Seam Sisitemu ya Gazi

Andika ubutumwa bwawe hano hanyuma ubwoherereze
