Chii chinonzi carbon steel pipe

1.Carbon simbi pombi

1.1.Carbon simbi pombi, kazhinji pane yakaderera tembiricha (isingasviki -20 ℃) ​​kushandiswa kwekabhoni simbi pombi kunofanirwa kuve GB6479 yakajairwa, chete inopa zvinhu zveyakadzika tembiricha inokanganisa kuoma zvinodiwa GB3087 uye GB5310 chiyero chakanyanya kugadzirirwa boiler simbi. pombi mitemo.

1.2.Carbon simbi pombi yakagadzirwa nekabhoni simbi, ine kabhoni inokwana 005% ~ 135%.

1.3.Steel pombi maererano nenyere zvinhu (inonzi simbi) inogona kukamurwa kuita: kabhoni chubhu uye alloy chubhu, Stainless simbi chubhu uye imwe kabhoni chubhu inogona kupatsanurwa kuva zvakajairika kabhoni pombi uye yepamusoro kabhoni chimiro chubhu alloy chubhu inogona kupatsanurwa kuita : yakaderera alloy chubhu, alloy chimiro chubhu, yakakwira alloy chubhu, yakakwira simba chubhu.

2.carbon simbi pombi yakasimba

2.1.Carbon simbi pombi yakasimba, Q345 isina musono pombi / Q345 gobvu madziro pombi / Q345 isina musono gobvu madziro pombi/hombe dhayamita Q345 isina musono pombi /Q345 kabhoni simbi pombi ishoma alloy akatevedzana - yakaderera alloy yakakwirira simba structural simbi (GB/T1591-1994) .

2.2.Iyo "stainless steel chubhu" ndiyo cathode, iyo "carbon steel chubhu" ndiyo anode, iyo yakakura mutsauko unokwanisa pakati pezviviri ndiko kukura kwegalvanic corrosion tendency.

2.3.Kabhoni simbi inoshandiswa mumaindasitiri simbi kabhoni simbi inoita basa rakakosha muinowanzo shandiswa kabhoni simbi kabhoni yemukati kazhinji isingasviki 13%, simba riri nani uye kuomarara kana zvichienzaniswa nesimbi yealloy, kabhoni simbi kunyunguduka kuri nyore, kugadzirisa nyore, mutengo wakachipa, kazhinji unogona. kusangana nezvinodiwa zvekuita, zvakashandiswa zvakanyanya.

3. Ko carbon steel pipe ndeyerudzii

3.1.Carbon simbi pombi ndeyerudzii rwepombi, kabhoni simbi pombi: rudzi rwesimbi pombi alloy, kugadzirwa kweyakajairwa kabhoni simbi pombi inowanzokamurwa kuva yakakwirira, yepakati uye yakaderera kabhoni mhando nhatu dzepamusoro kabhoni simbi pombi kabhoni yemukati ndiyo yakanyanya kukwirira. , kazhinji inodarika 06 muzana, asi isu tinoziva kuti iyo yakakwira iyo kabhoni yemukati yebrittleness yayo yakakura, saka yakakwira kabhoni simbi pombi haiwanzo kushandiswa kugadzira maindasitiri.

3.2 simbi pombi 40cr zvinoreva -40cr is 40 chromium, CR ndiyo chidimbu che chrome (chromium), 40cr ndeye alloy simbi Cr inogona kuwedzera kuoma kwesimbi, kuvandudza kusimba uye kudzikamisa kugadzikana kwesimbi, ine yakanakisa mechaniki zvivakwa chikamu saizi kana yakakosha tempering workpiece, inofanira kushandiswa Cr simbi asi Cr simbi ine yechipiri mhando tempering brittleness.

3.3.Carbon simbi pombi inogadzirwa nesimbi ingot kana yakasimba simbi simbi yakaputirwa muchubhu yemvere dzemakwai, uye yobva yapisa yakakungurutswa, inotonhora yakakungurutswa kana kutonhora inodhonzwa kabhoni simbi pombi imhando yesimbi chubhu alloy, kugadzirwa kwakajairwa kabhoni simbi pombi inowanzokamurwa kuita yakakwirira. , yepakati uye yakaderera kabhoni mapoka matatu.
