Mu rwego rw'ubwubatsi n'ibikorwa remezo, guhitamo ibikoresho bigena mu buryo butaziguye kuramba n'imikorere myiza y'umushinga. Muri byo harimo:Umuyoboro wa ASTM A252, nk'igikoresho cy'ingenzi mu buhanga bw'imizingo y'amabuye, ishimwa cyane n'inganda kubera imikorere yayo myiza yo gushyigikira. Iyi nkuru izahuza ibicuruzwa by'inganda zikora ibintu byiza cyane i Cangzhou, yibande ku gusesengura Ingano z'umuyoboro wa ASTM A252naIngano z'imiyoboro ya ASTM A252, kandi tugaragaze imikorere ihebuje y'imiyoboro ya A252 yo mu bwoko bwa 3 spiral ikoreshwa mu buryo bunyuranye n'imiyoboro y'amazi mabi yo mu kigo cyacu.
Umuyoboro wa ASTM A252 ni iki?
Ibipimo ngenderwaho bya ASTM A252 bikubiyemo imiyoboro y'icyuma ivanze kandi idakora neza ikoreshwa mu buhanga bw'imizingo, ikoreshwa cyane mu biraro, ku rufatiro rw'inyubako ndende n'izindi nyubako zikenera imbaraga nyinshi n'ubufasha bwizewe. Iri hame rigabanyijemo ibice bitatu, muri byo imiyoboro yo mu cyiciro cya 3 ikora neza cyane mu gukomera no kuramba, kandi ikwiriye cyane cyane iyo ikoreshwa mu bintu biremereye kandi biremereye.
Isesengura ry'ibipimo by'umuyoboro wa ASTM A252 n'ibisobanuro byawo
Ku bahanga mu by’imishinga n’abafata ibyemezo, gusobanukirwa neza ingano y’imiyoboro ya ASTM A252 ni ingenzi mu guhitamo igishushanyo mbonera. Ubu bwoko bw’imiyoboro butanga ingano z’imiyoboro ya ASTM A252 ihindagurika. Ubusanzwe uburebure bw’umurambararo bushobora kuba hagati ya santimetero 6 na santimetero 60, kandi ubugari bw’urukuta bushobora guhindurwa hakurikijwe ibisabwa by’ubuhanga.
Urugero, ibipimo bisanzwe by'imiyoboro bishobora kuba umurambararo wa santimetero 12 n'ubugari bw'urukuta bwa santimetero 0.375. Dushyigikira umusaruro wihariye kugira ngo buri muyoboro ube ufite imiterere ya mekanike n'ubudahangarwa busabwa kuri uwo mushinga, uhaza ibyifuzo byose kuva ku buhanga bw'umujyi kugeza ku bikorwa remezo binini by'inganda.
Imbaraga z'ikigo: Byakorewe i Cangzhou, ubuziranenge bwatanzwe
Isosiyete yacu iherereye mu Mujyi wa Cangzhou, mu Ntara ya Hebei. Kuva yashingwa mu 1993, yiyemeje gukora imiyoboro y'ibyuma no guhanga udushya mu ikoranabuhanga. Iyi sosiyete ifite ubuso bwa metero kare 350.000, ifite umutungo wa miliyoni 680 z'amayuani kandi ikoresha abantu bagera kuri 700. Twashyizeho ibikoresho mpuzamahanga bigezweho byo gukora no gupima kugira ngo buri wese arebe koUmuyoboro wa ASTM A252kuva mu ruganda byujuje cyangwa birengeje amahame ngenderwaho y’inganda.
Umuyoboro wa A252 wo mu cyiciro cya 3 ukozwe mu buryo bwa Spiral arc Welded: Amahitamo meza ku miyoboro y'amazi mabi
Igicuruzwa cy’ingenzi cy’ikigo cyacu, umuyoboro wa A252 wo mu bwoko bwa 3 spiral submerged arc welded, ukorwa hakoreshejwe uburyo bwo gusudira arc submerged spiral (SAWH). Umugozi wo gusudira ni umwe kandi ukomeye, ufite imbaraga nyinshi muri rusange kandi urwanya cyane gukanda no kunama.
Iki gicuruzwa gikozwe mu cyuma cyiza kandi gifite ubushobozi bwo kurwanya ingese no kwangirika, bigatuma kiba cyiza cyane mu bidukikije bikomeye nko gutunganya imyanda no gutwika imigozi y'ifatizo. Dushyira mu bikorwa uburyo bwo kugenzura ubuziranenge mu gihe cyose cy'igikorwa. Kuva ku bikoresho fatizo byinjira mu ruganda kugeza ku bicuruzwa birangiye biva mu ruganda, buri gikorwa gikurikiza amahame ya ASTM A252 kugira ngo harebwe ingano nyayo y'imiyoboro n'imikorere yizewe.
Umwanzuro
Umuyoboro wa ASTM A252 ufite uruhare rudasimburwa mu bikorwa remezo bigezweho. Ingano z'imiyoboro ya ASTM A252 ihindagurika hamwe n'ibipimo byayo bya ASTM A252 bisanzwe bitanga garanti ikomeye ku mishinga itandukanye y'ubuhanga. Nk'ikigo gikomeye mu nganda mu gace ka Cangzhou, gifite imyaka 30 y'ikoranabuhanga rikusanyije kandi giharanira ireme, duha abakiriya ibicuruzwa byizewe cyane kandi biramba bya A252 grade 3 spiral submarine arc welded. Guhitamo twe bivuze guhitamo uburyo burambye kandi butanga icyizere ku mushinga wawe w'ibikorwa remezo.
