Factory Supply China Ms Round Low Carbon Seamless Steel Pipe Black Iron Seamless Simbi Pipe Yakashandiswa Kugadzira Petroleum Pipeline.
Overview
Isu tinovavarira kutsvaga kukanganiswa kwemhando kubva mukugadzirwa uye nekupa sevhisi yakanakisa kune vatengi vekumba nekumhiri kwemakungwa nemoyo wese kune Seamless Simbi Pipe Inoshandiswa kuPetroleum Pipeline, Kana iwe uchinakidzwa mune chero chero mhinduro dzedu kana ungada kukurukura yakagadziriswa odha. , yeuka kunyatsonzwa wakasununguka kutibata nesu. Isu tinopa akasiyana makuru ezvigadzirwa uye mhinduro munzvimbo ino. Kunze kwezvo, maodha akasarudzika anowanikwawo. Uyezve, iwe unonakidzwa nemabasa edu akanaka. Mushoko rimwe chete, kugutsikana kwako kunovimbiswa. Kugamuchirwa kushanyira kambani yedu! Kuti uwane rumwe ruzivo, iva nechokwadi chekuuya kuwebhusaiti yedu.Kana paine mimwe mibvunzo, ndapota inzwa wakasununguka kutibata.
Nhanganyaya kuAPI 5L pombi yesimbi pombi/Musiyano uripo pakati peAPI 5L PSL1 uye PSL2 zviyero
API 5L kazhinji inoreva chiyero chekushandiswa kwemapombi esimbi, ayo anoshandiswa kutakura oiri, chiutsi, mvura, nezvimwe zvakabviswa kubva pasi kuenda kupetroleum uye gasi rechisikigo maindasitiri emaindasitiri. Mitsetse mapaipi zvinosanganisira musono simbi pombi uye welded simbi pombi. Parizvino, anowanzo shandiswa welded simbi pombi mhando mumapaipi emafuta muChina anosanganisira spiral undermerged arc welded pombi (SSAW), longitudinal submerged arc welded pombi (LSAW), uye yemagetsi kuramba welded pombi (RW). Seam simbi mapaipi anowanzo kusarudzwa kana pombi dhayamita isingasviki 152mm.
Pane magiredhi akawanda ezvigadzirwa zvepi 5L simbi mapaipi: GR.B, X42, X46, X52, X56, X60, X70, X80, nezvimwewo. Iye zvino zvigayo zvihombe zvesimbi seBaosteel zvakagadzira mamakisi esimbi eX100, X120 pipeline simbi. Yakasiyana simbi mamakisi emapombi esimbi ane yakakwirira zvinodiwa pambishi uye kugadzira, uye iyo kabhoni yakaenzana pakati peakasiyana simbi mamakisi inodzorwa zvakanyanya.
Kana zvasvika kuAPI 5L, munhu wese anoziva kuti pane zviyero zviviri, PSL1 uye PSL2. Kunyangwe paine musiyano wezwi rimwe chete, zviri mukati mezviyero zviviri izvi zvakasiyana zvakanyanya. Izvi zvakafanana neGB/T9711.1.2.3 chiyero. Vose vanotaura pamusoro pechinhu chimwe, asi zvinodiwa zvakasiyana zvikuru. Zvino ndichataura nezve musiyano uripo pakati pePSL1 nePSL2 zvakadzama:
1. PSL ndicho chidimburidzo chedanho rekutsanangurwa kwechigadzirwa. Iyo yechigadzirwa yekumisikidzwa nhanho yemutsetse pombi yakakamurwa kuita PSL1 uye PSL2, zvinogona zvakare kutaurwa kuti nhanho yemhando yakakamurwa kuita PSL1 uye PSL2. PSL2 yakakwirira kudarika PSL1. Aya mazinga maviri ekutsanangurwa haana kungosiyana chete mune zvinodiwa zvekuongorora, asiwo mukugadzirwa kwemakemikari uye michina. Naizvozvo, kana uchiraira maererano ne API 5L, mazwi ari muchibvumirano haangoratidzi zviratidzo zvakajairwa senge zvakatemwa uye simbi mamakisi. , Inofanirawo kuratidza chiyero chechigadzirwa, kureva, PSL1 kana PSL2. PSL2 yakaomarara kupfuura PSL1 muzviratidzo zvakaita sekuumbwa kwemakemikari, tensile zvivakwa, simba rekuita, uye kuyedza kusiri kuparadza.
2. PSL1 haidi kukanganisa kushanda. Kune ese magiredhi esimbi ePSL2 kunze kwex80, avhareji kukosha kweAkv pachiyero chakazara pa0 ° C: longitudinal ≥ 41J, transverse ≥ 27J. X80 simbi giredhi, yakazara-chiyero 0 ℃ Akv avhareji kukosha: longitudinal ≥ 101J, mhiri ≥ 68J.
3. Mapombi epombi anofanirwa kuongororwa ne hydrostatically imwe neimwe, uye chiyero hachipi chekutsiva kusingaparadzi kwekumanikidza kwemvura. Uyu zvakare mutsauko mukuru pakati peiyo API chiyero uye yeChinese standard. PSL1 haidi kuongororwa kusingaparadze, PSL2 inofanira kunge isiri-inoparadza yekuongorora imwe neimwe.
Application
Iyo pombi inoshandiswa kutakura oiri, chiutsi uye mvura inodhonzwa kubva pasi kuenda kumabhizinesi emafuta negasi indasitiri kuburikidza nepombi.
