GB13296-2013 (Seamless simbi pombi kuti boilers uye kupisa exchangers). Inonyanya kushandiswa mumaboilers, superheaters, heat exchangers, condensers, catalytic tubes, nezvimwe zvemakemikari emabhizinesi. Inoshandiswa yakakwirira-tembiricha, yakakwirira-kumanikidza, corrosion-resistant simbi pombi. Mumiririri wayo zvinhu 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, etc. GB/T14975-1994 (Stainless simbi seamless simbi pombi nokuda chimiro). Iyo inonyanya kushandiswa kune yakajairwa dhizaini (yehotera uye yekushongedza yekudyira) uye mekiniki chimiro chemakemikari emabhizinesi, ayo anopesana nemhepo uye asidhi corrosion uye ane mamwe masimba esimbi mapaipi. Zvishandiso zvayo zvinomiririra 0-3Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, nezvimwe.

GB/T14976-2012 (Stainless simbi isina musono pombi yekufambisa mvura). Inonyanya kushandiswa mapaipi anotakura corrosive media. Zvishandiso zvinomiririra 0Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 0Cr18Ni12Mo2Ti, nezvimwe.

YB/T5035-2010 (Seamless simbi mapaipi emotokari ekisero maoko). Inonyanya kushandiswa kugadzira yakakwirira-mhando kabhoni structural simbi uye alloy structural simbi inopisa-yakakungurutswa seamless simbi mapaipi emotokari hafu-axle maoko uye axle machubhu edhiraivha axle housings. Zvishandiso zvaro zvinomiririra 45, 45Mn2, 40Cr, 20CrNi3A, nezvimwe.

API SPEC 5L-2018 (mutsara wepombi yakatarwa), yakanyorwa uye yakabudiswa neAmerican Petroleum Institute, inowanzoshandiswa pasi rose.

Mutsara pombi: inosanganisira isina musono uye welded pombi. Migumo yepombi ine migumo yakati sandara, yakarukwa magumo uye socket inogumira; nzira dzekubatanidza kuguma kusungirirwa, kubatana kwekubatanidza, socket connection, nezvimwe zvinhu zvikuru GR.B, X42, X52. X56, X65, X70 uye mamwe mamakisi esimbi.

API SPEC5CT-2012 (Casing and Tubing Specification) inounganidzwa uye yakapihwa neAmerican Petroleum Institute (American Petreleum Instiute, inonzi "API") uye inoshandiswa munzvimbo dzese dzepasi.

mu:

Casing: Pombi inosimuka kubva pasi ichipinda mutsime uye inoshanda sechitubu chemadziro. Mapombi akabatanidzwa nekubatanidza. Zvishandiso zvikuru magiredhi esimbi akadai seJ55, N80, uye P110, uye magiredhi esimbi akadai seC90 neT95 anoshingirira ku hydrogen sulfide corrosion. Yayo yakaderera simbi giredhi (J55, N80) anogona welded simbi pombi.

Tubing: Pombi inopinzwa mucasing kubva pasi pevhu kusvika kune mafuta layer, uye mapaipi anobatanidzwa nekubatanidza kana kubatanidzwa. Basa rayo nderekubvumira chikwata chekupomba kuti chitakure mafuta kubva pamafuta kusvika pasi kuburikidza nehutu. Zvishandiso zvikuru magiredhi esimbi akadai J55, N80, P110, uye C90, T95 ayo anoshingirira ku hydrogen sulfide corrosion. Yayo yakaderera simbi giredhi (J55, N80) anogona welded simbi pombi.
