Izosi ry'umugozi

A ijosi ry'umugozini kenshi itoranywa igihe ihuriro ryitezwe gutwara ibirenze umukazo gusa. Mu migambi nyayo, abaguzi barayihitamwo kubera koigihimba c'umubiri + igitsina-izosi ry'umugozigutanga uguhinduka kw’imibabaro kuva ku ruhande gushika ku muyoboro, ivyo bikaba bifasha mu mirongo ishikiwe n’guhinduka kw'umuvuduko, uguhinduka kw'ubushuhe, ukunyiganyiga, umuyoboro w'uruhome uremereye-, canke ibisabwa bikomeye vyo gusuzuma.

Ku bijanye n’ugutanga amasoko, ivyo si uguhitamwo gusa umuco w’ibarabara. Kenshi na kenshi ni ingingo yerekeye .kwizigirwa kw'amahuriro, gutunganya ivyuho, ubutungane bw'ugusudira, n'ugushikama kw'igikorwa c'igihe kirekire-. Izosi ry'ivyuma bihuye n'ivyourugero, guhangana, uburebure, urutonde, n'ibikoreshoakenshi izotuma habaho ingorane nkeyi z'ugushikana -up kurusha flange yatowe gusa n'ubunini bw'izina n'umugwi.

Igihe abaguzi baronderaizosi ry'umugozicankeizosi ry'umugozi, akenshi ntibarondera gusa kuraba nimba ico kintu kiri mu bubiko. Ico bakeneye kwemeza vy’ukuri ni nimba iyo flange izoja ku murongo n’iyo .umurongo w'umugambi, urutonde rw'imiyoboro, ubwoko buhanganye, urugero rw'ibikoresho, n'uburebure bw'isuzumabimaze gusobanurwa mu gishushanyo canke PO. Mu kugura vy'ukuri, ingorane nyinshi ntiziva ku "nta vyo gutanga" - ziva ku bintu vyinshi bitafunzwe kare, nk'ibarabara ry'uruhome rw'imiyoboro ridakwiriye, ukuraba nabi, canke ibisabwa vy'inyandiko bibura bituma mu nyuma bigabanya kwemererwa no gushirwaho.

Insobanuro y’ugugura ikwiye gusobanura flange biciye muri ibi bibanza vyo gusuzumiramwo:

Umurongo wa RFQ ukomeye cane akenshi wandikwa gutya:

ASME B16.5, ijoro ry'ibara ry'agahama, NPS 4, Igitigiri ca 600, RF, ASTM A105, ry'umuyoboro wa Sch 80, MTR ikenewe, Igitigiri ___

Ivyo biratekanye cane kuruta kwandika gusa ngo "4 inch weld neck flange," kuko bigenzura ingingo zisanzwe zituma kwakira amatati:guhangana, umupira w'amaguru, ibikoresho,kandiUburebure bw'inyandiko.

A ijosi ry'umugozini kenshi itoranywa igihe umurongo witezwe gukoraumukazo mwinshi, ubushuhe burengeye, gusubiramwogutwara amagare y'ubushuhe, ukunyiganyiga, cankeiremereye-umuyoboro wo ku ruhomeaho ukwizigirwa kw’abafatanyabikorwa guhambaye kuruta ukuntu ibintu bimeze neza. Mu migambi nyayo, ikoreshwa cane mu mirongo y’ugutwara amavuta na gazi, mu mazu y’isuku n’amatiyo y’amavuta, mu bice vyo mu kiyaga, mu mirongo y’amazi, mu guhuza ubwato bw’umuvuduko-, mu gukoresha umuyagankuba, no mu yindi mirongo y’ubuhinga canke y’ubuhinga buhambaye.

Muri izo nsiguro, flange si ikintu co gufatanya gusa. Bigira ingaruka zitaziguye kuri:

• kwimurira umuzigo
• ubunyankamugayo
• igihe kirekire-gukingira gushikama

Uvuye ku kubona kw’umuguzi, agaciro k’ibara ry’izosi ry’ivyuma kararushiriza gutomoka iyo igiciro co kunanirwa ari kinini. Igisohoka kw’ishami ry’umuvuduko munini-, gusubira gukora bitewe n’ugutunganya nabi, canke gukosora kw’ivyuma vyinshi mu gihe co gushiramwo-up bishobora gutwara amahera menshi kuruta ivyuma ubwavyo.

Inyungu zayo nyamukuru ziva ku .Igihugu gipfutsekandiigitsina-izosi ry'amabuye, ivyo bikaba bifasha gutuma haba uguhinduka gutomoye hagati y’ibarabara n’umuyoboro. Mu majambo ngirakamaro, ivyo bisigura:

• vyizagutunganya ububore
• ihinduka ry'igice ridatunguranye ahantu h'ugusudira
• gutera imbere mu gukwiriyeSerivisi y'ingendokandiukunyiganyiga-imirongo igaragara
• Uburyo bwiza bwo gusudira kugira ngo umuntu asuzume
• kwizigirwa caneisuzuma ry'amaradiyo
• gukomeyeumuyoboro -ku -ugukomeza

Ni co gituma abahinga kenshi bakunda amabara y’izosi y’ivyuma ku buryo bw’amatiyo asaba cane aho ukwizigirwa kw’ibikorwa vy’igihe kirekire-guhambaye kuruta umuvuduko wo gushiramwo.

Guhitamwo ibikoresho bikwiye gukurikiza uko igikorwa gikorwa, atari ibikoresho canke igiciro gusa. Ku bijanye na flanges z’izosi ry’ivyuma, ibikoresho bikwiye guhura n’urugero rw’imiyoboro, ubushuhe bwo guhingura, ibidukikije vy’ugusenyuka, n’ibisabwa vyo gusuzuma/gushiramwo inyandiko z’umugambi. Igipande gishobora kuba gifise ingero zigororotse, ariko iyo igikoresho kidahuye n’umugwi w’umurongo, kiracari ikintu canse.

Muri rusangi,ASTM A105ikoreshwa mu gukora amatiyo y’icuma c’umuyagankuba mu gihe c’ibikorwa bisanzwe.ASTM A350 LF2ni vyiza ku bikorwa vy'ubushuhe buke-aho ubukomezi bw'ingaruka buhambaye. Ku bijanye n'ubushuhe bwinshi -amatiyo y'ivyuma, abaguzi akenshi bavugaF11, F22, canke F91kugira ngo ugume uhuye n’ibikoresho vy’imiyoboro be n’ingene ikora. Mu gikorwa co gusenyura,F304 / F316ni amahitamwo asanzwe atagira ibara, mu giheinzu zibiri / inzu zibiri canegrades zirabereye cane iyo vyose bikenewe ko umuntu ashobora guhangana na chloride be n’inkomezi nyinshi. KuriUmuyoboro w'umunani, ubwo bwoko bw’uguhuza ibikoresho ni kimwe mu bintu vy’ishimikiro vyo kugenzura mu gutanga amajambo y’ivyuma no gusubiramwo urutonde, kubera ko urugero rw’ibikoresho rugira ico rukoze ata guca ku ruhande ku kwemererwa, ku guhuza n’ugusudira, no ku kwizigirwa kw’ibikorwa vya nyuma.

Akarorero koroshe: ku murongo w'umwotsi, uguhitamwo kw'ibarabara si ku bijanye n'ubunini n'umugwi - ibikoresho navyo bitegerezwa kuguma bishikamye ku bushuhe, rero ibiharuro vy'ivyuma nk'F11cankeF22bishobora gukenerwa aho gukoresha ivyuma vy’umuyagankuba. Ku murongo w'ubushuhe buke-, ukoreshejeA105ahoLF2.bishobora gutuma haba ingorane yo gukomera naho vyose ari ivy’ivyuma vy’ivyuma vy’ivyuma. Uvuye ku bijanye n’amasoko, urugero rw’ibikoresho rutari rwo akenshi rutera ingorane nini kuruta ubwoko butari bwo bw’ibarabara, kuko bigira ico bikoze ku kwemererwa, ku guhuza n’ugusudira, no ku kwemerwa kw’umugambi wa nyuma.

Muri make, abaguzi akenshi bimukira muri .izosi ry'umugozi n'ugunyerera -kuguhitamwo igihe iyo nzira irushiriza gusaba kandi ingorane zo gusohoka, urushe canke gusubiramwo gusanasana zikaba zigoye kwirengagiza.

Muikimenyetso c'izosini ngirakamaro ku bishushanyo, BOMs, na RFQs kubera ko amakosa menshi yo gusubiramwo amajambo atangura n’ugushiramwo amajambo atari meza canke adatunganye.

Mu nyandiko z'umugambi, amafomu magufi asanzwe ni:

• WN= Izosi ry'ugusudira
• WNRF= Izosi rya Weld Riduze Mu maso
• WNRTJ= Ubwoko bw'Impeta y'Izosi
• LWN= Izosi rirerire
• RWNcanke amajambo adondora ashobora gukoreshwa mu kugabanya imiterere y'izosi ry'ivyuma bivanye n'ingene umuntu akora igishushanyo

Iciyumviro nyamukuru ku baguzi ni uko ikimenyetso conyene kitahagije. "WN" igaragaza ubwoko bw'ibarabara, ariko ntisobanuraikigo, guhangana, gutobora, ibikoresho,cankeibisanzwe. Igishushanyo kivuga gusa ngo "WN flange" kiracari gisiga umwanya munini cane w'ikosa ryo gusubiramwo amajambo. Ico kimenyetso gikwiye kwama gisomwa hamwe n’ijambo ry’uguhamagara ryuzuye.

Akarorero k'igishushanyo / BOM guhamagara:
WN, 6", Igitigiri ca 600, RF, ASTM A105, ASME B16.5, gica kuri Sch 80

Abaguzi bariko bararonderauburemere bw'izosiakenshi bagerageza gutorera umuti kimwe mu bibazo bitatu:Igereranyo ry'ibicuruzwa, guterura/gupakira,cankegushigikira-ugushiraho ibarura. Ikintu gihambaye ni uko uburemere bw’izosi ry’ibara ry’agahama ari .ntibigenzurwa n'ubunini gusa. Bihinduka cane na:

• ingano y'izina
• Ishure ry'umukazo
• uburemere bw'ibikoresho
• uburebure bw'igice
• ubwoko buhanganye
• ubunini bw'uburebure / urutonde rw'umukino

A Igitigiri ca 150 co gusudira izosinaIgitigiri ca 1500 co gusudira izosikuri iyo NPS nyene biragaragara ko itazokwigenza nk’ico kintu nyene mu gufata canke mu gutuma. Igipande co hejuru-class flange gitwara umugozi uremereye, umubiri munini, n'ubuhinga butandukanye bw'uruziga rw'amabuye, rero uburemere buraduga ningoga n'umugwi.
Uburemere bw’izosi ry’ivyuma bukwiye kwemezwa bivuye ku meza canke igishushanyo c’ivyo bikoresho, hanyuma bigasubirwamwo n’ibikoresho vy’ukuri be n’imiterere y’ivyo bikoresho imbere y’uko ingingo zo gutwara canke zo gufasha zisozwa.

Kuberaijosi ry'umugozi, kwemera akenshi bifatwa ingingo bikeyi kubera umurongo w’inyuma kandi vyinshi bifatwa n’uko .umugozimu vy’ukuri bihuye n’umuyoboro uzoshirwako. Iciyumviro cose c’umugambi w’izosi ry’ivyuma ni uguhingura inzira nziza kuva ku nzira y’ibarabara gushika ku ruhome rw’imiyoboro. Iyo iyo nzira idakomeye cane, irengeje urugero canke gusa ihuye n’urutonde rutari rwo, uwo musudira asunikwa mu bikorwa vyo gukosora mu murima nk’ivyo .gusya imbere, guvanga, hi-low guhindura, canke indishi y'imiterere y'ivyuma. Ivyo ntibituma gusa -up - bigenda buhoro, birashobora kandi kugira ico bikoze ku guhuza kw'ivyuma, kwemera amasanamu, n'inzira ya nyuma y'uruja n'uruza ku ntumbero.

Ivyo bica biba ivy’agaciro cane ku wa 2019.iremereye-umuyoboro wo ku ruhome, imigambi n'Urutonde rwinshi, kugabanya inzira, umuvuduko munini-Serivisi ya RTJ, cankeijosi rirerireifatanye n’amazi y’ubwato canke y’ibikoresho. Muri ivyo bihe, ukudahuza kw’ivyuma si ikintu gitoyi co gutera ingorane mu mahugurwa. Bishobora gutuma haba intambwe yo mu mutima ku bijanye n’ugusudira, kwongera igihe co gukosora, no guhatira gukoresha imashini canke gusya vyinshi umuguzi atigeze ategura. Ni co gituma RFQ ikomeye idakwiye guhagarara kuri 10.00.NPS + Ishure. Ishobora kandi kuvuga ivyo bisabwa .Urutonde rw'imiyoborocanke gutanga intumberoUmurongo w'imbere, rero iyo flange irashika yiteguriye umuyoboro nyawo itegerezwa guhura, atari gusa ubunini bw’izina ku mpapuro.

Ku bijanye n’itegeko rikomeye ry’izosi ry’ivyuma, abaguzi akenshi bitwararika caneUtuntu two kwemera dushobora gupimwakurusha amajambo rusangi nk'aya "ugutahura neza cane."

Ivyo gusuzuma ngirakamaro birimwo:

• flange itegeko n'ivyemezo vy'ishure
• gusuzuma ubwoko buhanganye (RF / RTJ / FF)
• uburebure n'ingero z'umurongo
• uruziga rw'ubugozi n'ukuri kw'umwobo w'ububoti
• iherezo ry'amahembe canke igenzura ry'umurongo wa RTJ
• kwemeza gushirako ikimenyetso
• umubare w'ubushuhe ushobora gukurikirana kuri MTR
• PMI/UT/MT/PT aho bisabwa

Igipande c’izosi c’ivyuma kigaragara neza gishobora gutuma ahantu hateba iyoBore, guhangana, canke inyandikontimujane n’ivyo umugambi usaba.
