Inotungamira Simbi Mapaipi Mugadziri & Mutengesi MuChina |

Maitiro Akanyanya Kudzivirira Brittle Kutsemuka muCarbon Steel Pipes, Flanges uye Fittings.

Masimbi echinyakare anoita basa rakajairwa mukugadzirwa kwesimbi, ingave simbi isina tsvina inoshandiswa mumidziyo yekurapa kana yegungwa, chero yezvizvarwa zvemhando yepamusoro simbi dzakagadzirwa mumakumi mashoma emakore apfuura eindasitiri yemotokari, kana simbi dzakaita sealuminium uye. titanium.iyo ine simba rakakura kune huremu reshiyo uye yakakwira corrosion kuramba inoita kuti ive yakakosha kune maapplication muaerospace, kunatsa mafuta uye maindasitiri emakemikari.

Izvi zvinoshandawo kune mamwe kabhoni simbi alloys, kunyanya alloys ane imwe kabhoni uye manganese zvirimo.Zvichienderana nehuwandu hwezvinhu zvealloying, zvimwe zvacho zvakanyatsokodzera kugadzirwa kweflanges, fittingsuyemapaipimumakemikari nemafuta ekunatsa.Vose vane chinhu chimwe chete chakafanana: zvinhu zvinoshandiswa muzvikumbiro izvi zvinofanirwa kunge zviri ductile zvakakwana kuti zvikwanise kutsungirira brittle fracture uye stress corrosion cracking (SCC).

Zviyero masangano akadai seAmerican Society of Manufacturing Engineers (ASME) uye ASTM Intl.(yaimbozivikanwa seAmerican Society for Testing and Materials) inopa gwara panyaya iyi.Maviri ane hukama indasitiri makodhi-ASME Boileruye Pressure Vessel (BPVD) Chikamu VIII, Chikamu 1, uye ASME B31.3, Process Piping - kero kabhoni simbi (chero chinhu chine 0.29% kusvika 0.54% kabhoni uye 0.60% kusvika 1.65% manganese, iron ine zvinhu).inochinjika zvakakwana kuti ishandiswe munzvimbo dzinopisa, nzvimbo dzinodziya uye tembiricha dzakaderera se -20 degrees Fahrenheit.Nekudaro, zvipingamupinyi zvenguva pfupi yapfuura pakupisa kwe ambient zvakakonzera kuongororwa kwepedyo kwehuwandu uye huwandu hweakasiyana microalloying zvinhu zvinoshandiswa mukugadzira maflange akadaro, mafittings uye. api simbi mapaipi.

Kusvika nguva pfupi yadarika, hapana ASME kana ASTM yaida kuyedzwa kwemhedzisiro kuratidza ductility yeakawanda kabhoni simbi zvigadzirwa zvinoshandiswa patembiricha zvakaderera se -20 madhigirii Fahrenheit.Sarudzo yekusabvisa zvimwe zvigadzirwa yakavakirwa pane zvenhoroondo zvezvinhu.Semuenzaniso, kana iyo shoma simbi dhizaini tembiricha (MDMT) iri -20 madhigirii Fahrenheit, inosununguka kubva mukukanganisa bvunzo nekuda kwechinyakare basa rayo mukushandisa kwakadaro.
