Numuyoboro wicyuma utagira kashe ugomba kuba wujuje imiterere yimiti nibisabwa mumitungo ya Grade B ya API 5L, ASTM A106, na ASTM A53 icyarimwe.
Ubu bwoko bwumuyoboro burashobora gukoreshwa muburyo bworoshye mumishinga itandukanye utiriwe uhangayikishwa nibibazo bisanzwe bihuza.Iyoroshya kandi gucunga ibarura mukugabanya gukenera kugura imiyoboro yuburyo butandukanye.
Icyitonderwa: Ni ngombwa kumenya ko API 5L GR.B hano yerekeza kuri API 5L PSL1 icyiciro B.
Botop Steelni uruganda rukomeye rukora imiyoboro yicyuma nububiko mubushinwa, kabuhariwe mu gukora no gutanga imiyoboro ya karubone idafite icyerekezo cyo gukoresha amazi na peteroli.Kuva twashingwa mu 2014, ibicuruzwa byacu byoherejwe mu bihugu byinshi n'uturere nka Ositaraliya, Kanada, Ubuhinde, Arabiya Sawudite, n'ibindi, kandi twakusanyije uburambe mu bucuruzi mpuzamahanga.
Dukora imiyoboro yicyuma twubahiriza cyane amahame mpuzamahanga nka API 5L, ASTM A106, na ASTM A53 kugirango ibicuruzwa byujuje ubuziranenge kandi bisanzwe.Urutonde rwibicuruzwa rutwikiriye imiyoboro idafite ibyuma idafite uburebure bwa mm 10.3 - 660 mm n'ubugari bwa mm 2 - 100.
Hamwe na toni zirenga 8000 zicyuma kitagira ibyuma mububiko, turashobora kwemeza ko bidatinze ubunini busanzwe.Kubwoko bwihariye nubunini, turatanga kandi serivise yumusaruro yihariye kugirango twuzuze ibisabwa byabakiriya.
Imiyoboro idafite ibyumabikozwe mubikorwa bibiri byingenzi: kurangiza bishyushye no gushushanya imbeho.
DN ≤ 40 irashobora gukora ubushyuhe burangiye cyangwa bukonje, ahanini bikonje.
DN ≥ 50 igomba gushyuha.Imiyoboro ikonje ikonje idafite ibyuma nayo iraboneka ubisabwe.
| Diameter | DN 6- 650 [NPS 1/8 - 26] |
| Ikigereranyo cyo hanze | 10.3 - 660 mm [0.405 - 26 muri.] |
| Icyiciro cy'ibiro | STD (Bisanzwe), XS (Ikomeye Ikomeye), XXS (Ikubye kabiri) |
| 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, |
Kugirango harebwe niba umuyoboro wujuje ibyangombwa bisabwa mu rwego rwa B mu byiciro bitatu byose, API 5L, ASTM A106, na ASTM A53, imiti y’ibikoresho igomba kugenzurwa cyane mugihe cyo gukora.Ibikurikira nibisabwa byihariye kubigize imiti yibi bipimo bitatu:
API 5L Icyiciro B Icyiciro cyimiti
ASTM A106 Urwego B Urwego rwa Shimi
ASTM A53 Icyiciro B Bigize imiti
| Ikizamini | API 5L PSL1 Icyiciro B. | ASTM A106 Icyiciro B. | ASTM A53 Icyiciro B. | |
| Tanga imbaraga, min | MPa [psi] | 245 [35.500] | 240 [35.000] | 240 [35.000] |
| Imbaraga zingana, min | MPa [psi] | 415 [60,200] | 415 [60.000] | 415 [60.000] |
Kugereranya ibyangombwa bisabwa muburyo bwa Grade B muri API 5L, ASTM A106, na ASTM A53 byerekana ko bafite ibyo basabwa kugirango bahangane kandi bitange imbaraga.Uku gushikama nirwo shingiro ryo guhanahana ibipimo ngenderwaho kandi byemeza ko ibicuruzwa byigituba bishobora gukoreshwa muburyo butandukanye bwa porogaramu utitaye kumitungo idahuye.

Usibye gutanga ibyuma byujuje ubuziranenge bidafite ibyuma,Botop Steelitanga serivisi zitandukanye zo gutwikira hejuru kugirango ikemure ibikenerwa bitandukanye byo kurinda ruswa hamwe nibidukikije.
Imiyoboro y'ibyuma isanzwe ishyirwa mubikorwa byo kurinda by'agateganyo no gukumira ruswa igihe kirekire.Dukunze kubona umuyoboro wicyuma udafite kashe ushyizwemo umwenda wirabura, ukoreshwa mukurinda byigihe gito kugirango ugabanye ruswa mugihe cyo gutwara inyanja no kubika umuyoboro.
Ubwoko busanzwe bwo gutwikira kurinda ruswa burimoirangi, ashyushye, 3LPE, FBE, n'abandi.Guhitamo igifuniko gikwiye ntabwo bifasha gusa kongera igihe cyumurimo wumuyoboro wibyuma ahubwo binagabanya neza ibikorwa rusange.
API 5L, ASTM A106, na ASTM A53 Icyiciro cya B icyiciro cya B kidafite icyuma gikoreshwa cyane muri sisitemu yo gutwara imiyoboro, amazi, gaze, numwuka.Imiyoboro nayo irakwiriye mugukora imigozi, flanges, nibindi bikorwa byo gukora.
Botop Steel yamye ishimangira ubuziranenge nkumuzi wibikorwa, ibyo twizera ko ari urufunguzo rwo gutsindira abakiriya ikizere no kumenyekanisha isoko.Mubikorwa byigihe kirekire byinganda, twakusanyije uburambe bukomeye nibibazo byinshi byatsinze.
