Ni umuyoboro w'icyuma udafite umugozi ugomba kuzuza ibisabwa mu miterere ya chimique n'imiterere ya mekanike bya Grade B bya API 5L, ASTM A106, na ASTM A53 icyarimwe.
Ubu bwoko bw'imiyoboro bushobora gukoreshwa mu buryo bworoshye mu mishinga itandukanye nta guhangayikishwa n'ibibazo bisanzwe byo guhuza ibintu. Binoroshya kandi gucunga ububiko bw'ibikoresho mu kugabanya gukenera kugura imiyoboro y'ibipimo bitandukanye.
Icyitonderwa: Ni ngombwa kumenya ko API 5L GR.B hano yerekeza kuri API 5L PSL1 grade B.
Botop Steelni ikigo gikomeye mu gukora imiyoboro y'ibyuma mu Bushinwa, cyihariye mu gukora no gutanga imiyoboro y'icyuma cya karuboni kidakora neza gikoreshwa mu mazi n'amavuta. Kuva twashingwa mu 2014, ibicuruzwa byacu byoherejwe mu bihugu byinshi n'uturere nka Ositaraliya, Kanada, Ubuhinde, Arabiya Sawudite, n'ibindi, kandi twabonye ubunararibonye bwinshi mu bucuruzi mpuzamahanga.
Dukora imiyoboro y'ibyuma twubahiriza amabwiriza mpuzamahanga nka API 5L, ASTM A106, na ASTM A53 kugira ngo dukore ibicuruzwa byiza kandi bihuje n'amahame. Ibicuruzwa bikubiyemo imiyoboro y'ibyuma idafite umugozi ifite umurambararo wo hanze kuva kuri mm 10.3 - 660 n'ubugari kuva kuri mm 2 - 100.
Dufite toni zisaga 8.000 z'imiyoboro y'icyuma idakora neza, dushobora kwemeza ko ingano zisanzwe zitangwa ako kanya. Ku bwoko n'ingano zidasanzwe, dutanga kandi serivisi zo gukora zihariye kugira ngo zihuze n'ibyo abakiriya bakeneye.
Imiyoboro y'icyuma idafite umushonobikorwa mu buryo bubiri bw'ingenzi: kurangiza bishyushye no gushushanya bikonje.
DN ≤ 40 ishobora gutuma irangizwa n'ibishyushye cyangwa ikonje, ahanini ikaba ikonje.
DN ≥ 50 igomba kuba ishyushye cyane. Imiyoboro y'icyuma ikonje kandi idahindagurika iraboneka iyo uyisabye.
| Ingano y'umurambararo | DN 6- 650 [NPS 1/8 - 26] |
| Ingano y'inyuma yagenwe | 10.3 - 660 mm [0.405 - 26 in.] |
| Icyiciro cy'ibiro | STD (Isanzwe), XS (Ikomeye Cyane), XXS (Ikomeye Cyane Cyane) |
| Ingengabihe No. | Gahunda ya 10, Gahunda ya 20, Gahunda ya 30, Gahunda ya 40, Gahunda ya 60, Gahunda ya 80, Gahunda ya 100, Gahunda ya 120, Gahunda ya 140, Gahunda ya 160, |
Kugira ngo umuyoboro wujuje ibisabwa ku miterere ya shimi yo mu cyiciro cya B cy’ibipimo bitatu, API 5L, ASTM A106, na ASTM A53, imiterere ya shimi y’ibikoresho igomba kugenzurwa neza mu gihe cyo gukora. Ibi bikurikira ni byo bisabwa ku miterere ya shimi yo muri ibi bipimo bitatu:
Uburyo bwa API 5L Grade B mu gukora imiti
Ibikoresho bya ASTM A106 Grade B bya shimi
Ibikoresho bya ASTM A53 Grade B bya chimique
| Ikizamini | API 5L PSL1 Icyiciro B | ASTM A106 Icyiciro B | ASTM A53 Icyiciro B | |
| Ingufu z'umusaruro, nibura | MPa [psi] | 245 [35.500] | 240 [35.000] | 240 [35.000] |
| Ingufu zo gukurura, nibura | MPa [psi] | 415 [60.200] | 415 [60.000] | 415 [60.000] |
Kugereranya ibisabwa mu byuma bya tekiniki bya Grade B muri API 5L, ASTM A106, na ASTM A53 bigaragaza ko bifite ibisabwa bimwe mu gukurura no gukomera kw'umusaruro. Uku guhindagurika ni cyo shingiro ry'uburyo ibi bipimo bihinduka kandi byemeza ko ibicuruzwa bya tubular bishobora gukoreshwa mu buryo butandukanye nta kwitaye ku miterere idahuye.

Uretse gutanga imiyoboro y'icyuma ifite ubuziranenge butagira umugozi,Botop Steelitanga serivisi zitandukanye zo gusiga hejuru kugira ngo ihuze n'ibikenewe bitandukanye byo kurinda ingese n'ibidukikije.
Ubusanzwe imiyoboro y'icyuma ishyirwa mu byiciro bibiri: uburinzi bw'agateganyo n'uburinzi bw'igihe kirekire. Akenshi tubona umuyoboro w'icyuma udakora neza utwikiriwe n'igitambaro cy'umukara, gikoreshwa mu gutanga uburinzi bw'igihe gito kugira ngo kigabanye ingese mu gihe cyo gutwara no kubika umuyoboro mu mazi.
Ubwoko busanzwe bw'imyambaro yo kurinda ingese burimoirangi, gushyushya mu mazi, 3LPE, FBEn'ibindi. Guhitamo irangi rikwiye ntibifasha gusa kongera igihe cy'umurimo w'umuyoboro w'icyuma ahubwo binagabanya neza ikiguzi cy'imikorere rusange.
Imiyoboro ya API 5L, ASTM A106, na ASTM A53 Grade B y'icyuma kidakora ikoreshwa cyane mu miyoboro yo gutwara umwuka, amazi, gazi n'umwuka. Iyi miyoboro irakwiriye kandi mu gukora imigozi, imigozi, n'ibindi bikorwa byo kuyikora.
Botop Steel yahoraga ishimangira ko ireme ari ryo shingiro ry'ikigo, twizera ko ari ryo pfundo ryo gutsindira icyizere cy'abakiriya no kumenyekana ku isoko. Mu bikorwa by'inganda birambye, twakusanyije ubunararibonye bwinshi n'imanza nyinshi zatsinze.
