Taw qhia: Nkag siab txog cov txheej txheem Seamless yeeb nkab
Kev tsim cov kav dej seamless steel yog cov txheej txheem tsim kho uas ua lub luag haujlwm tseem ceeb hauv kev lag luam uas lub zog, kev ntseeg siab, thiab kev ua tau zoo tsis yog - sib tham. Tsis zoo li cov kav dej welded lossis seamed, cov kav dej seamless yog tsim tsis muaj kev sib koom ua ke - ua rau lawv zoo tagnrho rau siab -siab, siab - kub, lossis corrosive ib puag ncig.
Hauv kev lag luam thoob ntiaj teb steel yeeb nkab,seamless steel kavyog dav siv nyob rau hauvroj thiab roj tsheb thauj mus los, tsim hluav taws xob, petrochemical, nkoj tsim, thiab cov tshuab hnyav. Rau cov neeg yuav khoom thiab cov kws tsim khoom, kev nkag siab yuav ua li cas cov kav dej no tau tsim pab hauv kev xaiv cov khoom tsim nyog rau cov kev xav tau tshwj xeeb.
Kab lus no muab cov ncauj lus kom ntxaws txog cov txheej txheem tsim cov yeeb nkab seamless - los ntawm cov khoom siv raw (billet) mus rau qhov kawg tshuaj ntsuam xyuas - thiab piav qhia yuav ua li casHuayang steel yeeb nkabua kom lub ntiaj teb -chav kawm zoo. Nws kuj ntxiv rau peb tsab xov xwm tseem ceeb,Qhov sib txawv ntawm Seamless Yeeb Nkab thiab Seam Pipe, uas tshawb nrhiav qhov sib txawv ntawm ob hom yeeb nkab.
Kauj Ruam 1 - Npaj Billet thiab cua sov
Txhua seamless yeeb nkab pib nrog akhoom cylindrical billet, feem ntau yog ua los ntawm siab - zoo carbon steel los yog hlau alloy. Cov billettshuaj muaj pes tsawg leeg, nrog rau cov pa roj carbon, manganese, sulfur, phosphorus, thiab alloying ntsiab, txiav txim siab qhov kawg ntawm cov yeeb nkab kev ua tau zoo.
Ua ntej ua, billets undergospectral tsom xam thiab kuaj ultrasoniclos xyuas kom meej uniformity thiab qhov tsis muaj qhov tsis xws luag. Thaum kuaj xyuas, lawv raug txiav mus rau qhov xav tau ntev thiabrhuab nyob rau hauv ib tug rotary hearth rauvmus kwv yees1200℃(2190℃F).
Cov cua kub kom zoo yog qhov tseem ceeb - yog tias lub billet nyob rau hauv -rhuab, nws tiv taus deformation; Yog hais tias overheated, nws txaus ntshai oxidation nto thiab scale tsim. Huayang Steel Pipe ua haujlwmcomputer- tswj cov cua sovkom tswj tau qhov kub thiab txias thiab lub zog efficiency thaum lub sij hawm no.
Kauj Ruam 2 - Piercing thiab Elongation
Cov theem tom ntej yogtho qhov, uas hloov cov khoom cua sov rau hauv lub plhaub hollow. Qhov no feem ntau ua tiav siv covMannesmann piercing txheej txheem, muaj npe tom qab German engineers uas tsim nws nyob rau hauv lub xyoo pua puv 19.
Nyob rau hauv tus txheej txheem no, lub kub billet yog tig thiab ib txhij nias los ntawm ob skewed rollers, uas tsim internal tensile stresses ntawm qhov chaw, ua rau cov hlau rupture thiab tsim ib tug kab noj hniav. Atho qhov mandreltom qab ntawd txuas cov kab noj hniav, tsim cov ntxhib puab txoj kab uas hla ntawm cov yeeb nkab.
Tom qab piercing, lub plhaub hollow txav mus rau qhovelongation zeblos yogplug zeb, qhov twg nws yog stretched thiab elongated mus cuag lub Desired phab ntsa thickness thiab txoj kab uas hla. Cov hlau cov nplej ntws aligns longitudinally, muab seamless kav superiormechanical zogthiabsiab tsis kampiv nrog welded kav.
Kauj Ruam 3 - Kub Rolling thiab Sizing
Thaum elongated, cov yeeb nkab nkag muskub dovlos kho nws cov kab uas hla sab nrauv thiab phab ntsa uniformity. Thaum lub sij hawm txoj kev no, nws dhau los ntawm ib tug series ntawmpeb- yob lossis ncab-txo millsuas zuj zus zoo thiab du cov yeeb nkab qhov ntev.
Kev tswj qhov kub thiab txias tseem ceeb heev; dov feem ntau tshwm sim ntawm850-1050 degree. Kev tswj kom txias kom ntseeg tau qhov tseebmicrostructure- sib npaug ntawm ferrite thiab pearlite theem - rau toughness thiab ductility.
Tom qab dov, cov yeeb nkab nkag mus rau hauvsizing zeb, uas ua kom paub meej cov kab npoo sab nraud raws li cov qauv thoob ntiaj teb xws liASTM A106, API 5L, EN 10216, los yogTIAB SA 17175.

Kauj Ruam 4 - Kev kho cua sov thiab ua kom tiav
Tom qab kub dov, cov kav dej feem ntau raug rauKev kho cua sovtxhawm rau txhim kho lawv cov khoom siv kho tshuab. Cov txheej txheem kho cua sov feem ntau suav nrog:
normalizing- Cua sov saum toj no transformation kub thiab cua txias kom refine lub grain qauv.
Annealing-Slow cua sov thiab txias kom txhim kho ductility thiab machinability.
Quenching thiab Tempering- Rau siab - qib alloy muaj zog los txhim kho hardness thiab hnav tsis kam.
Tom qab kev kho cua sov, qhov chaw tiav yog ua, suav nrogpickling, txhaj tshuaj blasting, thiaboiling, tshem tawm nplai thiab tiv thaiv corrosion thaum thauj thiab khaws cia.
Ntawm Huayang, txhua lub raj xa dejtsis yog -kev kuaj kev puas tsuaj (NDT)xws li kev kuaj ultrasonic (UT), eddy tam sim no kuaj (ET), thiab kuaj hydrostatic (HT) txhawm rau txheeb xyuas cov teeb meem sab hauv lossis sab nraud ua ntej xa khoom kawg.
Kauj Ruam 5 - Kev Tshuaj Xyuas Zoo thiab Ntawv Pov Thawj
Txhua qhov seamless yeeb nkab yuav tsum ua tau raws li cov qauv nruj raws li cov qauv thoob ntiaj teb xws liASTM, ASME, API, EN, thiab ISO. Kev tshuaj xyuas npog ob qho tib sitxhua yamthiabtshuajkhoom:
| Hom kev xeem | Lub hom phiaj | Yam yuav tsum tau muaj |
|---|---|---|
| Tensile Test | Ntsuas lub zog | Ntau dua lossis sib npaug rau 415 MPa (ASTM A106 Gr. B) |
| Yield Test | Txiav txim siab elasticity | Ntau dua lossis sib npaug li 240 MPa |
| Flattening Test | Xyuas kom ductility | Tsis tawg los yog tawg |
| Hydrostatic Test | Siab tsis kam | 5-25 MPa |
| NDT (UT/ET) | Kev kuaj pom tsis raug | 100% kev pabcuam |
Huayang Steel Pipe tswj kev ua haujlwm siab hauv - tsev kuaj thiab txais yuavAPI Q1, ISO 9001, thiab PEDkev tswj kom zoo. Txhua lub raj xa nrog aDaim ntawv pov thawj zeb xeem (MTC), xyuas kom tag nrho traceability los ntawm raw khoom mus rau cov khoom kawg.
Kev sib piv nrog Welded Pipe Manufacturing
Hos seamless kav yog tsim los ntawm cov khoom billets,welded los yog seamed kavkeeb kwm los ntawmdov steel phaj los yog coilsuas yog khoov thiab welded raws ib seam. Ob txoj kev tsim khoom sib txawv ntawm cov txheej txheem, nqi, thiab kev ua haujlwm:
| Feature | Seamless Yeeb Nkab | Welded yeeb nkab (ERW / SAW) |
|---|---|---|
| Manufacturing Base | Khoom Billet | Hlau Phaj los yog Coil |
| Seam | Tsis muaj | Longitudinal los yog kauv |
| Siab Resistance | Siab heev | Nruab nrab mus rau siab |
| Tus nqi tsim khoom | Siab dua | qis |
| Qhov Loj | Mus txog 610 mm | Mus txog 1422 mm (LSAW) |
| Hom qauv | ASTM A106, API 5L | ASTM A53, API 5L, EN10219 |
Koj tuaj yeem nyeem ntxiv txog cov kev sib txawv no hauv peb tsab xov xwm tseem ceeb,Qhov sib txawv ntawm Seamless Yeeb Nkab thiab Seam Pipe, uas tshawb txog qhov sib txawv ntawm cov tshuab, cov nqi, thiab daim ntawv thov sib txawv.
