Chii chinonzi Hot Rolled Seamless Pipe?

Mapombi akakosha kumaindasitiri akaita seoiri negesi, kuvaka, motokari, uye kugadzira michina. Pakati pemarudzi akasiyana-siyana,inopisa yakakungurutswa isina musono pombiinomira pachena nekuda kwesimba rayo, kufanana, uye kugona kutsungirira kudzvanywa kwakanyanya uye tembiricha. Kusiyana nemapombi akaiswa, mapaipi asina musono haana weld seam, izvo zvinoita kuti ive yakanaka kune yakakosha maapplication. Muchikamu chino, tichaongorora kuti chii chinopisa chakakungurutswa chisina musono pombi, kuti inogadzirwa sei, mabhenefiti ayo, uye mashandisirwo ayo akajairika mumaindasitiri.

1. Tsanangudzo: Chii chinonzi Hot Rolled Seamless Pipe?

A inopisa yakakungurutswa isina musono pombiimhando yepombi yesimbi inogadzirwapasina weldinguye akaumbwa kuburikidza ainopisa rolling process. Izwi rekuti "seamless" rinoratidza kuti pombi haina chero mubatanidzwa kana musono pamwe nekureba kwayo, izvo zvinowedzera simba rayo uye kuvimbika.

Kukunguruka kunoreva kugadzira pombi patembiricha dzakakwirira, kazhinji pamusoro pe1000 ° C, zvichiita kuti simbi igadziriswe nyore nyore uye inogadziriswa. Iyi nzira inoguma mune yakasimba, homogeneous pombi yakakodzera kune dzakasiyana siyana dzinoda zvikumbiro.

2. Kupisa Yakakungurutswa Seamless Pipe Inogadzirwa Sei?

Kugadzirwa kwepombi inopisa yakatenderedzwa isina musono kunosanganisira akati wandei matanho akakosha:

a) Billet Kugadzirira

• A solid cylindrical steel billet inochekwa kusvika paurefu hunodiwa.

• Iyo billet inopisa muchoto kusvika kune tembiricha yepamusoro kuti iite kuti igadzikane.

b) Kuboora

• Iyo billet inopisa inopfuudzwa nepaguyo rinoboora kugadzira nzvimbo isina mhango.

• Iyo inotenderera inoboora uye rollers inoshandiswa kugadzira iyo yakakosha tubular chimiro.

c) Kurebesa

• Iyo pierced billet (ikozvino yava hollow chubhu) inopfuudzwa nepazvigayo zvekurebesa senge mandrel mill kana plug mill.

• Zvigayo izvi zvinotambanudza chubhu uye kukwenenzvera ukobvu hwemadziro uye dhayamita.

d) Kupisa kunopisa

• Iyo chubhu inowedzerwa kuumbwa uye hukuru kuburikidza neanopisa anokungurutsa mill.

• Izvi zvinovimbisa kufanana uye chiyero chechokwadi.

e) Kutonhodza uye Kururamisa

• Iyo pombi inotonhorera pane conveyor kana mumhepo.

• Inobva yatwasanudzwa yogurwa kuita hurefu hwaidiwa.

f) Kuongorora uye Kuedzwa

• Mapombi anoedzwa akasiyana-siyana asiri ekuparadza uye anoparadza (semuenzaniso, ultrasonic, hydrostatic).

• Kumaka uye kurongedza kunoitwa zvinoenderana neindasitiri zviyero.

sakysteelinopa inopisa yakakungurutswa isina musono mapaipi mune akasiyana mamakisi uye saizi, yakaedzwa zvizere uye yakasimbiswa yemhando yekusimbisa.

3. Zvinhu Zvikuru zveHot Rolled Seamless Pipe

• Seamless Structure: Hapana welded seam inoreva zvirinani kudzvinyirira kuramba uye kuvimbika kwechimiro.

• High Temperature Resistance: Inogona kumira kupisa kwakanyanya pasina deformation kana kutadza.

• Kushivirira Kudzvinyirira: Kuita kwakanakisa pasi pepamusoro mukati kana kunze kwekumanikidzwa.

• Uniform Wall Ukobvu: Hot rolling inovimbisa zviri nani ukobvu kudzora.

• Yakanaka Surface Pedzisa: Kunyangwe zvisiri kutsvedzerera semapombi anodhonzwa nechando, pombi dzinopisa dzakakungurutswa dzine kupera kunogamuchirwa kushandiswa kwemaindasitiri.

4. Zvinhu uye Maitiro

Mapombi anopisa akakungurutswa asina musono anowanikwa mumhando dzakasiyana siyana zvichienderana nekushandisa:

Common Materials:

• Carbon simbi (ASTM A106, ASTM A53)

• Alloy simbi (ASTM A335)

• Simbi isina tsvina (ASTM A312)

• Yakaderera-tembiricha simbi (ASTM A333)

Common Standards:

• ASTM

• SH/DIN

• API 5L / API 5CT

• JIS

sakysteelinopa kuteedzera kuzere nemaitiro epasi rose kuti asangane nezvinodiwa zvemisika yepasirese.

5. Zvikumbiro zveHot Rolled Seamless Pipe

Mapaipi anopisa akakungurutswa asina musono anoshandiswa muzvikamu zvakawanda nekuda kwekuvimbika uye kuita kwavo.

a) Indasitiri yeOiri neGasi

• Kutakura crude oil uye natural gas

• Downhole tubing uye casing

• Mapaipi ekunatsa

b) Kugadzira Simba

• Boiler tubes
