Ndi chitoliro chachitsulo chosasunthika chomwe chiyenera kukwaniritsa zofunikira za mankhwala ndi makina a Grade B a API 5L, ASTM A106, ndi ASTM A53 nthawi yomweyo.
Chitoliro chamtunduwu chitha kugwiritsidwa ntchito mosavuta pama projekiti osiyanasiyana popanda kuda nkhawa ndi zovuta zofananira.Imathandiziranso kasamalidwe ka zinthu pochepetsa kufunika kogula machubu amitundu yosiyanasiyana.
Zindikirani: Ndikofunika kudziwa kuti API 5L GR.B apa ikutanthauza API 5L PSL1 giredi B.
Botop Steelndi kutsogolera zitsulo chitoliro wopanga ndi stockist ku China, okhazikika mu kupanga ndi kotunga wozungulira mosalekeza mpweya zitsulo chitoliro kwa ntchito madzi ndi mafuta.Chiyambireni kukhazikitsidwa kwathu mu 2014, zinthu zathu zatumizidwa kumayiko ambiri ndi zigawo monga Australia, Canada, India, Saudi Arabia, ndi zina zotero, ndipo tapeza zambiri pa malonda apadziko lonse.
Timapanga mapaipi achitsulo motsatira kwambiri miyezo yapadziko lonse lapansi monga API 5L, ASTM A106, ndi ASTM A53 kuti titsimikizire zinthu zapamwamba komanso zokhazikika.Zogulitsazo zimakwirira mapaipi opanda zitsulo okhala ndi ma diameter akunja kuchokera 10.3 - 660 mm ndi makulidwe kuchokera 2 - 100 mm.
Pokhala ndi matani opitilira 8,000 a mapaipi achitsulo opanda msoko omwe ali m'gulu, timatha kuwonetsetsa kuti makulidwe ake amaperekedwa mwachangu.Kwa mitundu ndi makulidwe apadera, timaperekanso ntchito zopangira makonda kuti zikwaniritse zofunikira zamakasitomala.
Machubu opanda zitsuloamapangidwa m'njira ziwiri zazikulu: kumaliza kotentha ndi kujambula kozizira.
DN ≤ 40 imatha kupanga kutentha kutha kapena kuzizira kukokedwa, makamaka kuzizira.
DN ≥ 50 idzakhala yotentha.Machubu achitsulo osakanizidwa ndi ozizira amapezekanso mukapempha.

Pofuna kuwonetsetsa kuti chitoliro chikukwaniritsa zofunikira zamagulu a Gulu B pamiyezo yonse itatu, API 5L, ASTM A106, ndi ASTM A53, kapangidwe kake kazinthuzo kuyenera kuyendetsedwa mwamphamvu panthawi yopanga.Izi ndi zofunika zenizeni za kapangidwe kakemidwe kamiyezo itatuyi:
API 5L Grade B Chemical Composition
ASTM A106 Gulu B Chemical Mapangidwe
ASTM A53 Gulu B Chemical Mapangidwe
| Yesani | API 5L PSL1 Gulu B | ASTM A106 Gawo B | ASTM A53 Gulu B | |
| Mphamvu zokolola, min | MPa [psi] | 245 [35,500] | 240 [35,000] | 240 [35,000] |
| Mphamvu zolimba, min | MPa [psi] | 415 [60,200] | 415 [60,000] | 415 [60,000] |
Kuyerekeza kwa zomwe zimafunikira pamakina a Gulu B mu API 5L, ASTM A106, ndi ASTM A53 zikuwonetsa kuti ali ndi zofunika zomwezo pakulimba komanso zokolola.Kusasinthika kumeneku ndiye maziko a kusinthasintha kwa miyezoyi ndikuwonetsetsa kuti zinthu za tubular zitha kugwiritsidwa ntchito mosiyanasiyana popanda kukhudzidwa ndi katundu wosagwirizana.

Kuphatikiza pakupereka machubu achitsulo apamwamba kwambiri,Botop Steelamapereka ntchito zosiyanasiyana zokutira pamwamba kuti akwaniritse zosowa zosiyanasiyana zoteteza dzimbiri komanso chilengedwe.
Zovala zapaipi zachitsulo nthawi zambiri zimagawidwa m'magulu achitetezo osakhalitsa komanso kupewa dzimbiri kwa nthawi yayitali.Nthawi zambiri timawona chitoliro chachitsulo chosasunthika chokutidwa ndi zokutira zakuda, zomwe zimagwiritsidwa ntchito popereka chitetezo kwakanthawi kuti chichepetse dzimbiri pamayendedwe apanyanja ndikusungira chitoliro.
Mitundu yodziwika bwino ya zokutira zoteteza dzimbiri zimaphatikizapoutoto, otentha dip galvanizing, Mtengo wa 3LPE, FBE, ndi ena.Kusankha zokutira koyenera sikungothandiza kuwonjezera moyo wautumiki wa chitoliro chachitsulo komanso kumachepetsanso bwino ndalama zogwirira ntchito.
API 5L, ASTM A106, ndi ASTM A53 Giredi B chitoliro chachitsulo chosasunthika chimagwiritsidwa ntchito kwambiri pamapaipi otengera nthunzi, madzi, gasi, ndi mpweya.Machubu awa ndi oyeneranso kupanga ma bend, ma flanges, ndi zina zopangira maopaleshoni.
Botop Steel nthawi zonse imalimbikira pazabwino ngati muzu wabizinesi, zomwe timakhulupirira kuti ndiye chinsinsi cha kupambana kwamakasitomala komanso kuzindikira msika.Muzochita zamakampani anthawi yayitali, tapeza zokumana nazo zambiri komanso milandu yambiri yopambana.
