Ndi chitoliro chachitsulo chosasunthika chomwe chiyenera kukwaniritsa zofunikira za kapangidwe ka mankhwala ndi kapangidwe ka makina a Giredi B a API 5L, ASTM A106, ndi ASTM A53 nthawi imodzi.
Mtundu uwu wa chitoliro ungagwiritsidwe ntchito mosavuta m'mapulojekiti osiyanasiyana popanda kuda nkhawa ndi mavuto ogwirizana ndi zinthu zomwe zilipo. Zimathandizanso kuti kasamalidwe ka zinthu zikhale zosavuta pochepetsa kufunika kogula machubu a miyezo yosiyanasiyana.
Chidziwitso: Ndikofunikira kudziwa kuti API 5L GR.B pano ikutanthauza API 5L PSL1 grade B.
Chitsulo cha Botopndi kampani yotsogola yopanga mapaipi achitsulo komanso yogulitsa zinthu ku China, yomwe imadziwika bwino popanga ndi kupereka mapaipi ozungulira opanda kaboni achitsulo kuti agwiritsidwe ntchito pamadzi ndi mafuta. Kuyambira pomwe tidakhazikitsidwa mu 2014, zinthu zathu zatumizidwa kumayiko ndi madera ambiri monga Australia, Canada, India, Saudi Arabia, ndi zina zotero, ndipo tapeza chidziwitso chambiri pamalonda apadziko lonse lapansi.
Timapanga mapaipi achitsulo motsatira miyezo yapadziko lonse lapansi monga API 5L, ASTM A106, ndi ASTM A53 kuti tiwonetsetse kuti zinthu zili bwino komanso zokhazikika. Mitundu ya zinthuzi imaphimba mapaipi achitsulo opanda msoko okhala ndi mainchesi akunja kuyambira 10.3 - 660 mm ndi makulidwe kuyambira 2 - 100 mm.
Ndi mapaipi achitsulo okwana matani 8,000 omwe alipo, timatha kuonetsetsa kuti makulidwe okhazikika afika nthawi yomweyo. Pa mitundu ndi makulidwe apadera, timaperekanso ntchito zopangira zomwe zakonzedwa kuti zikwaniritse zosowa za makasitomala enaake.
Machubu achitsulo opanda msokoAmapangidwa m'njira ziwiri zazikulu: kumaliza kotentha ndi kujambula kozizira.
DN ≤ 40 imatha kupanga chokometsera chotentha kapena chozizira, makamaka chokometsera chozizira.
DN ≥ 50 iyenera kumalizidwa bwino. Machubu achitsulo opanda msoko okokedwa ndi ozizira amapezekanso ngati mungafune.

Pofuna kuonetsetsa kuti chitolirocho chikukwaniritsa zofunikira za kapangidwe ka mankhwala a Giredi B a miyezo yonse itatu, API 5L, ASTM A106, ndi ASTM A53, kapangidwe ka mankhwala ka zinthuzo kayenera kulamulidwa bwino panthawi yopanga. Izi ndi zofunikira zenizeni za kapangidwe ka mankhwala a miyezo itatu iyi:
Kapangidwe ka mankhwala a API 5L Giredi B
Kapangidwe ka Mankhwala a ASTM A106 Giredi B
Kapangidwe ka Mankhwala a ASTM A53 Giredi B
| Mayeso | API 5L PSL1 Giredi B | ASTM A106 Giredi B | ASTM A53 Giredi B | |
| Mphamvu yobereka, mphindi | MPa [psi] | 245 [35,500] | 240 [35,000] | 240 [35,000] |
| Mphamvu yokoka, mphindi | MPa [psi] | 415 [60,200] | 415 [60,000] | 415 [60,000] |
Kuyerekeza zofunikira za makina a Giredi B mu API 5L, ASTM A106, ndi ASTM A53 kukuwonetsa kuti ali ndi zofunikira zomwezo pa mphamvu yokoka ndi yotulutsa. Kugwirizana kumeneku ndiye maziko a kusinthana kwa miyezo iyi ndipo kumawonetsetsa kuti zinthu zozungulira zitha kugwiritsidwa ntchito m'njira zosiyanasiyana popanda kudera nkhawa ndi zinthu zosafanana.

Kuonjezera pa kupereka machubu achitsulo abwino kwambiri opanda msoko,Chitsulo cha Botopimapereka ntchito zosiyanasiyana zophimba pamwamba kuti zikwaniritse zosowa zosiyanasiyana zoteteza dzimbiri komanso momwe zinthu zilili.
Zophimba mapaipi achitsulo nthawi zambiri zimagawidwa m'magulu awiri: chitetezo cha kanthawi kochepa komanso kupewa dzimbiri kwa nthawi yayitali. Nthawi zambiri timawona chitoliro chachitsulo chopanda msoko chophimbidwa ndi utoto wakuda, womwe umagwiritsidwa ntchito popereka chitetezo cha kanthawi kochepa kuti muchepetse dzimbiri panthawi yonyamula ndi kusunga chitolirocho panyanja.
Mitundu yodziwika bwino ya zokutira zoteteza dzimbiri ndi mongautoto, kupopera madzi otentha, 3LPE, FBE, ndi zina. Kusankha chophimba choyenera sikuti chimangothandiza kukulitsa moyo wa chitoliro chachitsulo komanso kumachepetsa bwino ndalama zonse zogwirira ntchito.
Mapaipi achitsulo opanda msoko a API 5L, ASTM A106, ndi ASTM A53 Giredi B amagwiritsidwa ntchito kwambiri m'mapayipi ponyamula nthunzi, madzi, gasi, ndi mpweya. Machubu awa ndi oyeneranso kupanga ma bend, ma flange, ndi ntchito zina zopangira.
Botop Steel nthawi zonse imagogomezera kuti khalidwe ndi maziko a bizinesi, chomwe tikukhulupirira kuti ndicho chinsinsi chopezera chidaliro cha makasitomala ndi kudziwika pamsika. Mu ntchito yanthawi yayitali yamakampani, tapeza zokumana nazo zambiri komanso milandu yambiri yopambana.
