Inotungamira Simbi Mapaipi Mugadziri & Mutengesi MuChina |

Chii chinonzi "Pipeline Steel"?

Pipeline simbi imhando yesimbi inoshandiswa kugadzira oiri uye gasi pombi yekufambisa masisitimu.Sechitunha chekutakura kureba kwemafuta uye gasi rechisikigo, iyo pombi system ine zvakanakira hupfumi, chengetedzo uye isina kukanganiswa.

Pipeline simbi yekushandisa

Pipeline simbimafomu echigadzirwa anosanganisira pombi dzesimbi dzisina musono uye pombi dzesimbi dzakashongedzwa, dzinogona kukamurwa kuita zvikamu zvitatu: alpine, nzvimbo dzakakwirira-sarufa uye kuiswa kwegungwa. Mapaipi aya ane hutsinye hwekushanda nharaunda ane mitsetse mirefu uye haasi nyore kuchengeta, uye ane hutsika hunodiwa hunodiwa. .

Matambudziko mazhinji anotarisana nesimbi yepombi anosanganisira: mazhinji emafuta uye gasi minda ari munzvimbo dzepolar, mazaya echando, magwenga, uye nzvimbo dzegungwa, uye mamiriro echisikigo akaomarara;kana kuti kuvandudza kushanda kwekufambisa, dhayamita yepombi inogara ichiwedzerwa, uye dhigirii yekuendesa inogara ichiwedzerwa.

Pipeline Steel Properties

Kubva pakuongororwa kwakazara kwemaitiro ekuvandudza kwepombi dzemafuta negasi, pombi yekuisa mamiriro, nzira huru dzekutadza uye zvikonzero zvekutadza, simbi yepombi inofanirwa kunge iine yakanaka michina zvivakwa (madziro gobvu, kusimba kwakakwira, kusimba kwepamusoro, kupfeka kuramba), uye inofanirwa kuve zvakare. hombe dhayamita,Inofanirawo kuve nedhayamita hombe, weldability, kutonhora uye kushoma tembiricha kuramba, corrosion resistance (CO2), kuramba mvura yegungwa neHIC, SSCC performance, nezvimwe.

①Simba repamusoro

Simbi yepombi haingodi kusimba kwepamusoro uye kusimba kwegoho, asi inodawo kuti goho reshiyo rive muchikamu che 0.85 ~ 0.93.

② Kusimba kwakanyanya

kusimba kwepamusoro kunogona kusangana nezvinodiwa zvekudzivirira kutsemuka.

③Yakadzika ductile-brittle shanduko tembiricha

Matunhu akaomarara uye mamiriro ekunze anoda simbi yepombi kuti ive netembiricha yakadzikira yakadzikira. Nzvimbo yeshear yeDWTT (Drop Weight Tear Test) yave iyo main control index kudzivirira kutadza kusimba kwepombi. iyo fracture shear nzvimbo yemuenzaniso ive ≥85% pane yakaderera yekushanda tembiricha.

④Kupokana kwakanyanya kune hydrogen-induced cracking (HIC) uye sulfide stress corrosion cracking (SSCC)

⑤ Zvakanaka welding performance

Weldability yakanaka yesimbi yakakosha kuve nechokwadi chekutendeseka uye welding mhando yepombi.

Pipeline Steel Standards

Parizvino, iwo makuru tekinoroji zviyero zveoiri uye gasi kutapurirana simbi mapaipi anoshandiswa munyika yangu anosanganisiraAPI 5L, DNV-OS-F101, ISO 3183, uye GB/T 9711, zvichingodaro.

① API 5L (mutsara wepombi kutsanangurwa) ndeye yakagashirwa zvakatemerwa zvakatemwa neMaine Petroleum Institute.

② DNV-OS-F101 (submarine pipeline system) inotsanangurwa yakanyatsogadzirwa neDet Norske Veritas yemapombi epasi pemvura.

③ ISO 3183 chiyero chakagadzirwa neInternational Organisation for Standardization pamamiriro ekutakura epombi dzesimbi dzekufambisa oiri uye gasi.Iyi chiyero haibatanidzi dhizaini uye kuiswa kwepombi.

④ Yazvino vhezheni yeGB/T 9711 ndiyo vhezheni ya2017. Iyi vhezheni yakavakirwa pa ISO 3183:2012 uye API Spec 5L 45th Edition. zvichibva pane zvese zviri zviviri.Mukuenderana nemaitiro maviri akataurwa, maviri echigadzirwa mazinga anotsanangurwa: PSL1 uye PSL2.PSL1 inopa chiyero chemhando yepiipi yemutsetse;PSL2 inowedzera zvinosungirwa zvinodiwa zvinosanganisira kuumbwa kwemakemikari, notch kuomarara, masimba ezvivakwa uye yekuwedzera isiri-inoparadza kuyedza (NDT).

API SPEC 5L uye ISO 3183 zvine simba pasi rose mutsara wepombi zvirevo.Kusiyana neizvi, makambani emafuta mazhinji munyika akajaira kutoraAPI SPEC 5L zvakatemwa seyakanyanya kutsanangurwa kwepombi simbi pombi kutenga.

Odha ruzivo

Chibvumirano chekuraira kwesimbi yepombi chinofanira kusanganisira ruzivo runotevera:

① Huwandu (huremu hwese kana huwandu hwakazara hwepombi dzesimbi);

② Normative level (PSL1 kana PSL2);

Simbi pombimhando (isina musono kanawelded pombi, chaiyo welding process, pipe end type);

④Kubva pazviyero, seGB/T 9711-2017;

⑤ simbi giredhi;

⑥Kunze kwedhayamita nekukora kwemadziro;

⑦ Kureba uye kureba mhando (isina-kucheka kana kucheka);

⑧ Sarudza kudikanwa kwekushandisa apendikisi.
