Pombi yesimbi isina musono yekuvaka (GB/T8162-2008) inoshandiswa pakuvaka mapaipi esimbi asina musono uye pakugadzira michina.

Inoshandiswa pakugadzira machubhu esimbi asina musono emapombi, midziyo, midziyo, zvinhu zvinosungirirwa uye zvivakwa zvemakanika

Kuvaka: chimiro chehoro, chivakwa chegungwa, chimiro chenhandare yendege, chiteshi chengarava, furemu yemusuwo wekuchengetedza, gonhi regaraji, magonhi esimbi akasimbiswa nemahwindo, madziro ekuparadzanisa emukati, chimiro chebhiriji retambo nevarindi vekuchengetedza mugwagwa mukuru, njanji, kushongedza, mapombi ekugara, mapombi ekushongedza

Zvikamu zvemotokari: kugadzira mota nemabhazi, maturusi ekufambisa

Kurima: Midziyo yekurima

Indasitiri: Michina, Rutsigiro rwezuva, munda wemafuta ekunze, michina yekuchera, michina yemagetsi nemidziyo yemagetsi, Injiniya, migodhi, zvinhu zvinorema uye zviwanikwa, Injiniya yekushanda, kugadzirisa zvinhu, zvikamu zvemichina

Kutakurwa: njanji dzevanofamba netsoka, nzira dzekudzivirira, zvivakwa zvesikweya, zviratidzo, michina yemugwagwa, fenzi

Kuchengetera zvinhu: masherufu esupamaketi, fenicha, midziyo yechikoro

Chiyero chikuru chepombi yesimbi

Q345, 15CrMo, 12Cr1MoV, A53A, A53B, SA53A, SA53B

Saizi yechubhu yesimbi isina musono uye kutsauka kunobvumidzwa

Chubhu yesimbi yekabhoni (GB/8162-2008)

Rudzi urwu rwepombi yesimbi inogadzirwa kazhinji inonyungudutswa ne converter kana open choto, zvinhu zvayo zvikuru isimbi yakanyungudutswa nesimbi yakapwanyika, huwandu hwesarufa nephosphorus musimbi hwakakwira kupfuura hwepombi yesimbi inogadzirwa nekabhoni yepamusoro, kazhinji sarufa ≤0.050%, phosphorus ≤0.045%. Hunhu hwezvimwe zvinhu zvinosanganisa alloying, zvakaita se chromium, nickel nemhangura, zvinounzwa musimbi nezvinhu zvinogadzirwa kazhinji hazvipfuuri 0.30%. Zvichienderana nezvinodiwa pakuumbwa uye mashandiro, huwandu hwepombi yesimbi inogadzirwa nesimbi iyi hunoratidzwa ne Q195, Q215A, B, Q235A, B, C, D, Q255A, B, Q275 nezvimwewo.

Cherechedza: “Q” ibhii rechiChinese remafonetiki rekuti yield “qu”, richiteverwa ne minimum yield point (σ S) value yegiredhi, richiteverwa nechiratidzo zvichienderana ne secret elements (sulfur, phosphorus) content kubva kumusoro kusvika pasi nekuchinja kwezvinhu zvekabhoni nemanganese, zvakakamurwa kuita magiredhi mana A, B, C, D.

Rudzi urwu rwemapaipi esimbi anobuda ndiwo akakura, kushandiswa kwacho kwakafara, akakungurutswa kuita plate, profile (denderedzwa, sikweya, yakati sandara, basa, groove, Angle, nezvimwewo) uye profile uye manufacturing welding steel pipe. Inonyanya kushandiswa mumaworkshop, bhiriji, ngarava nedzimwe zvivakwa uye mapaipi ekutakura mvura. Rudzi urwu rwesimbi runowanzo shandiswa zvakananga pasina kurapwa kwekupisa.

Pombi yesimbi ine simba rakaderera (alloy) ine simba rakawanda (GB/T8162-2008)

Pamusoro pehuwandu hwakati hwesilicon kana manganese, mapaipi esimbi ane zvimwe zvinhu zvakakodzera zviwanikwa zveChina. Zvakadai sevanadium (V), niobium (Nb), titanium (Ti), aluminium (Al), molybdenum (Mo), nitrogen (N), uye rare earth (RE) trace elements. Zvichienderana nemakemikari akagadzirwa uye zvinodiwa pakushanda, giredhi rayo rinomiririrwa neQ295A, B, Q345A, B, C, D, E, Q390A, B, C, D, E, Q420A, B, C, D, E, Q460C, D, E nedzimwe giredhi dzesimbi, uye zvinoreva zvakafanana nepaipi yesimbi yekabhoni.

Pamusoro pesimbi yegiredhi A neB, simbi yegiredhi C, GRADE D neGiredhi E inofanira kunge iine chimwe chezvinhu zvakacheneswa zvakaita seV, Nb, Ti neAl. Kuti simbi ivandudze mashandiro ayo, simbi yegiredhi A, B inogonawo kuwedzerwa kune imwe yadzo. Pamusoro pezvo, huwandu hwezvinhu zvakasara zveCr, Ni neCu huri pasi pe0.30%. Q345A, B, C, D, E ndiwo magiredhi anomiririra rudzi urwu rwesimbi, pakati pawo simbi yegiredhi A, B inowanzonzi 16Mn; Zvinopfuura chimwe chinhu chinofanira kuwedzerwa papipi yesimbi yegiredhi C nepamusoro, uye chinhu chimwe chete chinofanira kuwedzerwa pakupisa kwakaderera kune hunhu hwayo hwemakanika.

Chiyero chemhando iyi yemapaipi esimbi ekuvaka nesimbi yekabhoni. Ine zvakanakira zvekusimba kwayo kukuru, kushanda kwayo kwakazara, kushanda kwenguva refu, kushandiswa kwayo kwakafara uye kuenzanisa. Inoshandiswa zvakanyanya mumabhiriji, ngarava, mabhoyira, mota uye zvivakwa zvakakosha.
