Dab tsi yog Kub Rolled Seamless Yeeb Nkab?

Cov kav dej yog qhov tseem ceeb rau kev lag luam xws li roj thiab roj, kev tsim kho, tsheb, thiab tshuab tsim khoom. Ntawm ntau hom,kub dov seamless yeeb nkabsawv tawm rau nws lub zog, uniformity, thiab muaj peev xwm tiv taus siab thiab kub. Tsis zoo li welded kav, seamless kav tsis muaj weld seam, uas ua rau lawv zoo tagnrho rau cov kev siv tseem ceeb. Hauv tsab xov xwm no, peb yuav tshawb xyuas qhov kub dov seamless yeeb nkab yog dab tsi, nws yog tsim, nws cov txiaj ntsig, thiab nws cov kev siv ntau hauv kev lag luam.

1. Txhais: Dab tsi yog Kub Rolled Seamless Yeeb Nkab?

A kub dov seamless yeeb nkabyog ib hom steel yeeb nkab tsimtsis muaj vuamthiab tsim los ntawm akub dov txheej txheem. Lo lus "seamless" qhia tias cov yeeb nkab tsis muaj qhov sib txuas lossis seam raws nws qhov ntev, uas ua rau nws lub zog thiab kev ncaj ncees.

Kub dov yog hais txog kev tsim cov yeeb nkab ntawmkub kub, feem ntau siab dua 1000 ° C, tso cai rau cov hlau kom yooj yim zoo li tus thiab ua tiav. Txoj kev no ua rau muaj zog, homogeneous yeeb nkab haum rau ntau hom kev thov.

2. Yuav Ua Li Cas Kub Rolled Seamless Yeeb Nkab Ua?

Kev tsim cov kub dov seamless yeeb nkab muaj ob peb kauj ruam tseem ceeb:

a) Kev npaj Billet

• Ib qho khoom cylindrical steel billet yog txiav mus rau qhov ntev xav tau.

• Lub billet yog rhuab nyob rau hauv lub cub tawg mus rau ib tug high kub kom nws malleable.

b) Piercing

• Lub rhuab billet yog dhau los ntawm ib lub zeb tho los tsim ib qho chaw hollow.

• Lub rotating piercer thiab rollers yog siv los tsim cov qauv tubular.

c) Elongation

• Lub pierced billet (tam sim no lub raj hollow) yog dhau los ntawm elongation mills xws li mandrel mills los yog ntsaws mills.

• Cov mills no ncab lub raj thiab kho cov phab ntsa thickness thiab txoj kab uas hla.

d) Kub Rolling

• Lub raj yog ntxiv zoo li tus thiab loj los ntawm kub dov mills.

• Qhov no ua kom muaj kev sib haum xeeb thiab qhov tseeb.

e) Txias thiab Ncaj

• Cov yeeb nkab yog txias rau ntawm lub conveyor lossis hauv huab cua.

• Nws yog ces straightened thiab txiav mus rau hauv xav lengths.

f) Kev Tshawb Fawb thiab Kev Ntsuas

• Cov kav dej tau dhau los ua ntau yam kev sim tsis muaj kev puas tsuaj thiab kev puas tsuaj (xws li, ultrasonic, hydrostatic).

• Kev kos npe thiab ntim tau ua tiav raws li cov qauv kev lag luam.

sakysteel uamuab kub dov seamless kav nyob rau hauv ntau yam ntawm cov qib thiab qhov ntau thiab tsawg, tag nrho kuaj thiab ntawv pov thawj rau kev ruaj ntseg zoo.

3. Cov yam ntxwv tseem ceeb ntawm Kub Rolled Seamless Yeeb Nkab

• Seamless Structure: Tsis muaj welded seam txhais tau tias zoo dua lub siab ua haujlwm thiab kev ua haujlwm ruaj khov.

• Kub Kub Resistance: tuaj yeem tiv taus cua sov yam tsis muaj deformation lossis tsis ua haujlwm.

• Siab Tolerance: Kev ua tau zoo heev nyob rau hauv siab sab hauv lossis sab nraud.

• Uniform Phab Ntsa Thickness: Kub dov kom zoo dua thickness tswj.

• Zoo Nto tiav: Txawm hais tias tsis zoo li cov kav dej txias txias, cov kav dej kub dov tau ua tiav tiav rau kev siv.

4. Cov khoom siv thiab cov qauv

Kub dov seamless kav muaj nyob rau hauv ntau yam ntaub ntawv nyob ntawm daim ntawv thov:

Khoom siv:

• Cov pa roj carbon steel (ASTM A106, ASTM A53)

• Alloy hlau (ASTM A335)

• Stainless hlau (ASTM A312)

• Cov hlau tsis tshua muaj kub (ASTM A333)

Common Standards:

• ASTM

• EN/DIN

• API 5L / API 5CT

• JIS

• GB / T

sakysteel uamuab tag nrho ua raws li thoob ntiaj teb specifications kom tau raws li cov kev xav tau ntawm lub ntiaj teb no kev lag luam.

5. Daim ntawv thov ntawm Kub Rolled Seamless Yeeb Nkab

Kub dov seamless kav yog siv nyob rau hauv ntau yam sectors vim lawv kev ntseeg tau thiab kev ua tau zoo.

a) Kev lag luam roj thiab roj

• Kev thauj cov roj av thiab cov nkev ntuj

• Downhole tubing thiab casing

• Refinery pipelines

b) Lub Hwj Chim Loj

• Boiler raj

• Thaum tshav kub kub exchanger tubes

• Superheater Cheebtsam

c) Mechanical Engineering

• Tshuab qhov chaw thiab cov khoom

• Hydraulic thooj voos kheej kheej

• Gear shafts thiab rollers

d) Kev tsim kho thiab Infrastructure

• Cov qauv kev txhawb nqa thiab lub moj khaum

• Piping cov kav dej
