Mapombi esimbi asina musono anotora chinzvimbo chakakosha muindasitiri yemazuva ano uye anoshandiswa zvakanyanya mukuvaka, kugadzira michina, petrochemical nemamwe minda.EN 10210inonyatso tsanangura mapaipi esimbi asina musono ezvivakwa, pakati peiyo BS EN 10210-1 yakanangana neinopisa-yakakungurutswa isiri-alloy uye yakanaka-grained zvimiro zvesimbi. Magiredhi akajairwa muchiyero ichi anosanganisira S235GRH, S275JOH, S275J2H, S355JOH uye S355J2H.

Chekutanga, S235GRH isimbi yekutanga giredhi, inonyanya kushandiswa kune zvimiro zvikamu pasi pekunetseka kwakaderera uye kamuri tembiricha nharaunda. Iine simba regoho re235MPa, ine yakanaka weldability uye kutonhora kuumbwa, uye inokodzera kuvakwa kwakajairwa uye michina zvimiro.

Zvinotevera S275JOH uye S275J2H. S275JOH ine kusimba kwakanaka pa -20 ℃ uye goho resimba re275MPa, uye rinowanzo shandiswa pakuvaka zvivakwa uye mapurojekiti ebhiriji ane mitoro yepakati. S275J2H ine zvirinani kukanganisa kuoma pa -20 ℃, uye inokodzera zvikamu zvezvimiro zvinoda yakakwirira kuchengetedza chinhu.

S355JOHuyeS355J2Hisimbi dzakasimba. S355JOH ine kuomarara kwakanakisa pane ese tembiricha yekamuri uye yakaderera tembiricha (-20 ℃), ine goho simba re355MPa, uye inoshandiswa zvakanyanya mukushushikana kwakanyanya uye akakosha mapurojekiti ezvimiro, senge zvivakwa zvepamusoro-soro uye mabhiriji makuru. S355J2H ine kusimba kwepamusoro pa -20 ℃, uye inokodzera nzvimbo dzinotonhora zvakanyanya kana mapurojekiti anoda imwe vimbiso yekuchengetedza.

Iyo EN 10210 yakajairwa haingotauri zvakajeka chete kuumbwa kwekemikari uye michina zvimiro zvepombi dzesimbi, asi zvakare inoisa kumberi chaiko zvinodikanwa zvedimensional kushivirira, kunaka kwepamusoro, kusingaparadze kuyedzwa, nezvimwe. Izvi zvinogonesa kuenderana uye kuvimbika kwepombi dzesimbi panguva yekugadzira uye use.

Mapaipi esimbi asina musono anoumbwa neinopisa yekutenderedza tekinoroji, iyo inovapa yakanakisa michina zvivakwa uye yakanaka dimensional kurongeka. Iyo inopisa yekukungurusa nzira inogona kubvisa kushushikana mukati mepombi yesimbi, kugadzirisa kurongeka kwesimbi, uye kuwedzera kushanda kwayo kwakazara. Kuenzaniswa nemapombi esimbi akasungwa, mapaipi esimbi asina musono ane yakakwirira compressive, kukotama uye torsional simba, uye akakodzera kutsigirwa kwechimiro uye kufambisa kwemvura pasi pemamiriro akasiyana siyana ekushanda.

Kazhinji, mapaipi esimbi asina musono anogadzirwa zvinoenderana neEN 10210 zviyero anoratidza mashandiro akanaka mukuvaka uye maindasitiri minda. Simbi mapaipi emagiredhi akadai S235GRH, S275JOH, S275J2H, S355JOH, uye S355J2H vane hunhu hwavo uye vanogona kuzadzisa zvinodiwa zvemapurojekiti akasiyana. Kushandiswa kwavo kwakakura hakusi kungovandudza kunaka uye kuchengetedzeka kwemapurojekiti, asiwo kunosimudzira kusimudzira uye kuvandudzwa kwesimbi yezvinhu tekinoroji. Kusarudza mapaipi esimbi asina musono emagiredhi akakodzera uye zvakatemwa kwakakosha pakuona kugadzikana kwenguva refu uye mabhenefiti ehupfumi emapurojekiti.
