Ipombi yesimbi isina musono inofanirwa kusangana nezvinodiwa zvemakemikari uye zvehunhu hwemakanika zveGiredhi B yeAPI 5L, ASTM A106, uye ASTM A53 panguva imwe chete.
Rudzi urwu rwemapaipi runogona kushandiswa zviri nyore mumapurojekiti akasiyana pasina kunetseka nezvematambudziko ekushandiswa kwemidziyo. Izvi zvinoitawo kuti kuve nyore kutarisira zvinhu nekuderedza kudiwa kwekutenga machubhu ane mwero yakasiyana-siyana.
Cherechedza: Zvakakosha kuziva kuti API 5L GR.B pano inoreva API 5L PSL1 giredhi B.
Simbi yeBotopikambani inotungamira mukugadzira mapaipi esimbi uye muchengeti wezvinhu muChina, inyanzvi mukugadzira nekugovera mapaipi esimbi yekabhoni isina musono yekushandiswa kwemvura nemafuta. Kubva patakatangwa muna 2014, zvigadzirwa zvedu zvakatumirwa kunyika dzakawanda nenzvimbo dzakadai seAustralia, Canada, India, Saudi Arabia, nezvimwewo, uye takawana ruzivo rwakakura mukutengeserana kwenyika dzese.
Tinogadzira mapaipi esimbi tichitevedzera mitemo yepasi rose yakaita seAPI 5L, ASTM A106, uye ASTM A53 kuti tive nechokwadi chekuti zvigadzirwa zvemhando yepamusoro uye zvakajairwa zvinogadzirwa. Rudzi rwezvigadzirwa rwunofukidza mapaipi esimbi asina musono ane dhayamita yekunze kubva pa10.3 - 660 mm uye ukobvu kubva pa2 - 100 mm.
Tine matani anopfuura 8,000 emapombi esimbi asina musono aripo, tinokwanisa kuve nechokwadi chekuti saizi dzakajairika dzinounzwa nekukurumidza. Kune mhando dzakasiyana uye saizi, tinopawo masevhisi ekugadzira akagadzirirwa vatengi vedu kuti vasangane nezvinodiwa nevatengi vedu.
Machubhu esimbi asina musonozvinogadzirwa nenzira mbiri huru: kupedzisa kupisa uye kudhirowa kunotonhora.
DN ≤ 40 inogona kuita kuti iite seyakapiswa kana kuti inotonhora, kunyanya yakatorwa ichitonhora.
DN ≥ 50 inofanira kunge ichipisa. Machubhu esimbi asina musono anodhonzwa nechando anowanikwawo kana ukaakumbira.

Kuti pombi ikwanise kusangana nezvinodiwa zvemakemikari eGiredhi B yemitemo yese mitatu, API 5L, ASTM A106, uye ASTM A53, kuumbwa kwemakemikari echinhu ichi kunofanirwa kudzorwa zvakanyanya panguva yekugadzira. Izvi zvinotevera ndizvo zvinodiwa zvemakemikari emitemo iyi mitatu:
Kuumbwa kweMakemikari eAPI 5L Giredhi B
Kuumbwa kweMakemikoro eASTM A106 Giredhi B
Kuumbwa kweMakemikoro eASTM A53 Giredhi B
| Bvunzo | API 5L PSL1 Giredhi B | ASTM A106 Giredhi B | ASTM A53 Giredhi B | |
| Simba rekupa, min | MPa [psi] | 245 [35,500] | 240 [35,000] | 240 [35,000] |
| Simba rekusimba, min | MPa [psi] | 415 [60,200] | 415 [60,000] | 415 [60,000] |
Kuenzanisa zvinodiwa zvemakanika zveGiredhi B muAPI 5L, ASTM A106, uye ASTM A53 kunoratidza kuti zvine zvinodiwa zvakafanana zvekusimba kwekusimba uye kubereka. Kuenderana uku ndiko kwakakosha pakuchinjana kwezviyero izvi uye kunoita kuti zvigadzirwa zvemachubhu zvigone kushandiswa mumhando dzakasiyana siyana pasina hanya nemaitiro asina kuenzana.

Pamusoro pekupa machubhu esimbi asina musono emhando yepamusoro,Simbi yeBotopinopa mabasa akasiyana-siyana ekuputira pamusoro kuti isangane nezvinodiwa zvakasiyana zvekudzivirira ngura nemamiriro ekunze.
Mapaipi esimbi anowanzoiswa muzvikamu zviviri zvekudzivirira kwenguva pfupi uye kudzivirira ngura kwenguva refu. Tinowanzoona mapaipi esimbi asina musono akafukidzwa nependi nhema, iyo inoshandiswa kudzivirira kwenguva pfupi kuderedza ngura panguva yekufambisa nekuchengetedza mapaipi mugungwa.
Mhando dzakajairika dzemachira ekudzivirira ngura dzinosanganisirapendi, kupisa dip galvanizing, 3LPE, FBE, nezvimwewo. Kusarudza pendi yakakodzera hakungobatsiri chete kuwedzera hupenyu hwepombi yesimbi asiwo kunoderedza mari yekushandisa.
Mapaipi esimbi asina musono eAPI 5L, ASTM A106, uye ASTM A53 Grade B anowanzo shandiswa mumapaipi ekufambisa utsi, mvura, gasi, nemhepo. Machubhu aya akakodzerawo kugadzira makomba, maflange, uye mamwe mabasa ekugadzira.
Botop Steel yagara ichisimbirira kuti bhizinesi rive remhando yepamusoro, izvo zvatinotenda kuti ndizvo zvinoita kuti vatengi vavimbe uye vazivikanwe pamusika. Mukushanda kwenguva refu kweindasitiri, takaunganidza ruzivo rwakakura uye zviitiko zvakawanda zvakabudirira.
