Umuyoboro w'icyuma ushongeshejwe ku buryo buziguye kugira ngo ugire imbaraga n'imikorere myiza bitagira urugero ASTM A252

Ibisobanuro bigufi:

Ibi bisobanuro bigamije gutanga amahame ngenderwaho mu nganda zikoresha imiyoboro y'amazi, gazi na peteroli mu nganda zikora peteroli na gaze karemano.

Hari urwego rubiri rw'ibicuruzwa, PSL 1 na PSL 2, PSL 2 ifite ibisabwa bisabwa kugira ngo habeho ingano ya karuboni, gukomera kw'ibanga, imbaraga ntarengwa z'umusaruro n'imbaraga zo gukurura.

Ku bijyanye no guteza imbere ibikorwa remezo, sisitemu z'imiyoboro ni ingenzi cyane mu nganda zitandukanye. Gukoresha ibikoresho n'ubuhanga bukwiye mu kubaka imiyoboro bituma iramba, ikomera kandi yizewe, kandiumuyoboro w'icyuma uhujwe n'uruziga ASTM A252iri ku isonga muri iri terambere ry'ikoranabuhanga. Muri iyi blog, tuzareba neza ibyiza n'ibyiza by'iyi miyoboro itangaje yabaye ingenzi mu mishinga y'ubwubatsi igezweho.

Ikizamini cy'amazi

ibisobanuro by'ibicuruzwa1

Ingufu n'Ubudahangarwa bitagira urugero:

ASTM A252umuyoboro w'icyuma uhujwe n'uruzigaIkozwe mu cyuma cyiza cyane cyujuje ibisabwa bya ASTM A252. Iri hame rihamya imbaraga n'ubudahangarwa bw'imiyoboro, bigatuma ikoreshwa mu bikorwa bitandukanye birimo kohereza peteroli na gaze, gufunga ishingiro ry'imiyoboro n'ibikorwa remezo by'amazi. Imashini zo gusudira zizunguruka zongerera imbaraga n'ubudahangarwa bw'imiyoboro ku ngufu zo hanze, bigatuma ishobora kwihanganira ibidukikije bishyushye cyane n'ikirere kibi.

Uburyo bwiza bwo gukora neza no gukoresha neza amafaranga:

Kimwe mu byiza by'ingenzi by'umuyoboro w'icyuma wa ASTM A252 ukozwe mu buryo bwa spiral ni imikorere myiza cyane mu kuwushyiraho no kuwukoresha. Imiterere yawo yoroshye kuyitwara no kuyifata bitewe n'uko ari yo yoroshye kuyitwara ugereranyije n'ibindi bikoresho by'imiyoboro. Byongeye kandi, ubushobozi bw'iyi miyoboro bworohereza gupfunyika, bigagabanya ibisabwa ku bikoresho n'imiyoboro. Ibi ntibigabanya gusa igihe, ahubwo binagabanya cyane ikiguzi cyo kuwushyiraho, bigatuma ubwo bwoko bw'imiyoboro buba igisubizo gihendutse ku mishinga itandukanye.

Kubara uburebure bw'imiyoboro yo gusudira ikoze mu buryo bw'umwuka

Ubudahangarwa bw'ingufu bwongerewe:

Ingese ni ikibazo gikomeye mu miyoboro y'amazi, cyane cyane mu nganda zikora imiti n'ibintu bihumanya. Amahame ngenderwaho ya ASTM A252 yemera ko imiyoboro y'ibyuma ikoreshwa mu buryo bw'umwuka irwanya ingese neza. Iyi miyoboro ifite ibikingira nka epoxy cyangwa zinc bikora nk'imbogamizi ku bintu bihumanya, bikongera igihe cyo kuyikoresha no kugabanya ikiguzi cyo kuyibungabunga. Iki kintu ni ingirakamaro cyane cyane mu miyoboro yo munsi y'ubutaka cyangwa mu nyanja aho imiyoboro ihura n'ikirere kibi.

Ubushobozi bwo gutwara ibintu bwinshi:

Ikindi kintu cy'ingenzi kiranga umuyoboro w'icyuma wa ASTM A252 ni ubushobozi bwawo bwiza bwo gutwara imizigo. Ikoranabuhanga ryo gusudira rikoreshwa mu gukora rituma umuyoboro ukomera kandi ugashobora kwihanganira imitwaro iremereye. Byaba bikoreshwa mu kubaka ibiraro, ishingiro ry'inyubako cyangwa imiyoboro yo munsi y'ubutaka, iyi miyoboro itanga ubuziranenge buhanitse bw'inyubako, bigabanya ibyago byo kwangirika no kwemeza umutekano w'igihe kirekire w'imishinga itandukanye y'ibikorwa remezo.

Kubungabunga ibidukikije:

Muri iki gihe aho kurengera ibidukikije ari ikibazo gikomeye ku isi yose, guhitamo ibikoresho by'ubwubatsi bikwiye ni ingenzi cyane. Umuyoboro w'icyuma ukozwe mu cyuma gishongeshejwe mu buryo burambye (Spiral welded steel pipe ASTM A252) wubahiriza gahunda z'ubwubatsi zirambye bitewe nuko uramba kandi ushobora kongera gukoreshwa. Imiyoboro imara igihe kirekire kandi ishobora kongera gukoreshwa mu buryo bworoshye mu mpera z'ubuzima bwayo, bikagabanya gukenera gucukurwamo ibikoresho bishya mu gihe bigabanya imyanda n'ibyuka bihumanya ikirere.

Mu gusoza:

Umuyoboro w'icyuma ukozwe mu cyuma gishongeshejwe mu buryo bw'umwuka (Spired Steel Pipe ASTM A252) wahinduye urwego rw'imiyoboro kubera imbaraga zawo zidasanzwe, kuramba no kugabanya ikiguzi. Iyi miyoboro yujuje cyangwa irenga amahame y'inganda, bituma iba amahitamo ya mbere mu nganda nyinshi. Ubushobozi bwayo bwiza bwo gutwara imizigo no kurwanya ingese bitanga iterambere rirambye ry'imishinga y'ibikorwa remezo kandi bigatanga umusanzu mu guteza imbere inganda ku isi. Mu gukoresha iyi miyoboro, imishinga y'ubwubatsi ishobora kunoza imikorere, kugabanya ikiguzi no kwemeza ko irambye kandi igakomeza kubaho neza.

Ibanjirije iyi: Imiyoboro y'icyuma ishongeshejwe mu buryo bw'umwuka yo gukoresha imiyoboro y'amazi yo mu ngo

Ibikurikira: Umuyoboro wa Superior X65 SSAW Line: Igisubizo cyiza cyane ku bikorwa remezo by'imiyoboro binoze kandi byizewe

Andika ubutumwa bwawe hano hanyuma ubwoherereze
