API 5L X42 simbi pombi, inozivikanwawo seL290, inodaidzwa nekuda kwesimba rayo rekuita 42,100 psi (290 MPa).X42 ine simba shoma rekusimba re60,200 psi (415 MPa).
X42/L290 giredhi simbi pombi ndeyeyepasi giredhi uye inonyanya kushandiswa kune maapplication ane low pressure.Zvakadai sekutapurirana gasi remuguta, masisitimu ekufambisa kwemvura, uye mamwe masisitimu epombi ayo asingade kutakura-kumanikidza kwekutakura.
Levels
Zvichienderana nezvinodiwa zvekushanda, machubhu eX42 akakamurwa kuita maviri mazinga echigadzirwa,PSL1 uye PSL2.
PSL1ndiyo yekutanga giredhi mutsetse pombi yakatarwa.Inowanzo shandiswa mumasisitimu ekufambisa akajairwa uko mamiriro ekunze asina kunyanyisa.
PSL2igiredhi repamusoro.Yakagadzirirwa zvakanyanya kudiwa mamiriro, senge yakakwira-kudzvanywa nharaunda, uye zvakanyanya kuoma kana corrosive application.
Sarudzo yegiredhi ripi repiipi yesimbi yekushandisa zvinoenderana nezvinodiwa chaizvo zvepurojekiti, kusanganisira iyo inotarirwa nharaunda yebasa uye kusimba zvinodiwa.
Steel Pipe Manufacturing Process
Kugadzirwa kweX42 simbi machubhu inovhara akasiyana siyana ekugadzira matekiniki kuti asangane neakasiyana engineering uye zvakatipoteredza zvinodiwa.Kubva pakusina musono kusvika kumhando dzakasiyana-siyana dzematekinoroji, imwe neimwe nzira inopa yakasarudzika mabhenefiti uye nzvimbo dzekushandisa.

Izvo zvinodikanwa zvekuumbwa kwemakemikari zvePSL1 zvakadekara, nechinangwa chekuona kusimba uye kusimba kwechinhu.
API 5L X42 PSL2 Chemical Kuumbwa
PSL2 ine kudzora kwakasimba kwechimiro chemakemikari kuti ive nechokwadi chemhando yepamusoro uye mashandiro enzvimbo dzinodiwa uye mashandisirwo.
Mamwe mamakisi ePSL2 tubing akagadzirirwa chaizvo maapplication akakosha, kusanganisira zvinyorwa zvemukati "S" uye "O".Chivakashure che "S" chinoratidza kuti pombi yakagadzirirwa nharaunda dzakavava, nepo mapaipi ane "O" chivakashure chakagadzirirwa nharaunda dzepamhepo.
Nekuda kwekuti nharaunda idzi dzinonyanya kuita ngura, kuomarara kwepombi yesimbi kunovandudzwa nekushandura kemikari.

Zvakanakira zveX42 Giredhi Simbi Tubing
1. Mkusimba kwakanyanyisa uye kuomarara: X42 simbi pombi ine hushoma goho simba 42,100 psi (290 MPa), iyo inopa yakanaka mechanical simba apo kuchengetedza kuoma kwakaringana kutsungirira imwe chiyero mukati uye kunze kunetsa pasina kuputsika.
2. Weldability yakanaka: X42 pombi kazhinji ine zvakanaka weldability, izvo zvinoita kuti zvive nyore uye zvakanyanya hupfumi kuisa nekugadzirisa.Iyi ficha inonyanya kukosha kumapurojekiti epombi akareba, ayo anowanzoda basa rakawanda rewelding.
3.Inokodzera kushandiswa kwakaderera uye kwepakati-kudzvinyirira: Nekuda kwesimba rayo rine mwero goho, inonyanya kukodzera kune yakaderera uye yepakati-kudzvanywa zvikumbiro senge kanzuru gasi kutapurirana, kuderera-kudzvinyirira mvura kugovera masisitimu, nezvimwe. Izvi zvinoita kuti ive yakanaka kune akawanda manejimendi uye maindasitiri mapurojekiti ekuvaka.
4.Mutengo-kubudirira: Zvichienzaniswa nemagiredhi epamusoro (semuenzaniso X65, X70, nezvimwewo), X42 simbi pombi inowanzobatsira zvakanyanya maererano nekugadzira uye mutengo wekutenga.
5. Wide range of applicability: Inopa dzakasiyana siyana sarudzo dzezvakasiyana purojekiti zvinodiwa, nePSL1 yakakodzera kune zvakajairika mhando zvinodiwa uye PSL2 inokodzera kunyorera uko kukwirisa kunodiwa.
6. Kugadzirwa kwakarongeka: Sechikamu cheiyo API 5L yakajairwa, kugadzirwa uye kutonga kwemhando yeX42 simbi pombi kunotevera yakasimba indasitiri zviyero, izvo zvinovimbisa kunaka kwayo kuenderana uye kuvimbika.
X42 Steel Pipe Application

Paunenge uchisarudza chinhu chakaenzana, zvakakosha kuve nechokwadi chekuti chinhu chakasarudzwa chinosangana nezvinodiwa zvemakemikari, zvivakwa zvemakanika, uye mamwe mazinga akakodzera echishandiso chaicho.Pamusoro pezvo, maitiro ekugadzira, matanho ekusimbisa kunaka, uye mutengo-unoshanda zvingada kutariswa.
Nezvedu
Kubva payakavambwa muna 2014, Botop Steel yave mutengesi anotungamira wekabhoni simbi pombi kuChamhembe kweChina, inozivikanwa nebasa repamusoro, zvigadzirwa zvemhando yepamusoro, uye mhinduro dzakakwana.
Iyo kambani inopa akasiyana kabhoni simbi mapaipi uye zvine hukama zvigadzirwa,
zvinosanganisira isina musono, ERW, LSAW, uye SSAW simbi pombi, pamwe neyakakwana mutsara wepombi fittings uye flanges.Zvigadzirwa zvayo zvehunyanzvi zvinosanganisira alloys epamusoro-giredhi uye austenitic simbi isina tsvina, yakagadzirirwa kusangana nezvinodiwa zveakasiyana mapurojekiti epombi.
