Product Detail

Khoom cim npe

Seamless square steel tubing, Nws yog lub hardened martensitic stainless hlau alloy.Sib txawv ntawm qib austenite

Nws tuaj yeem kho cua sov ("quenched thiab tempered") los tsim lub zog siab thiab zoo ductility.Thaum xav tau lub zog, hardness thiab hnav tsis kam thiab muaj qee yam corrosion kuj

Vim tias muaj peev xwm hardening ntawm cov hlau no, lwm yam khoom ntawm cov khoom siv no thiab cov txiaj ntsig tshwm sim yuav raug cuam tshuam rau qee yam.Cov hlau tsuas tuaj yeem siv tau zoo hauv qhov chaw me me corrosive.Kev khiav hauj lwm kub ntau yog txwv a) tempering ntau dhau ntawm qhov kub thiab txias ua rau poob ntawm lub zog thiab b) poob ntawm ductility ntawm sub-zero kub

Seamless square steel tubing, Cov hlau no yog qhov zoo tagnrho rau kev tsim cov khoom muaj kev ntxhov siab hauv ntau yam kev lag luam, suav nrog petrochemicals, tsheb thiab hluav taws xob tsim.

Seamless Square Steel Tubing, Qhov Kev Ua Haujlwm Tseem Ceeb

1. Cov yas
Plasticity yog hais txog lub peev xwm ntawm cov khoom siv hlau los tsim cov yas deformation (mus tas li deformation) yam tsis muaj kev puas tsuaj nyob rau hauv load.

2. Lub hardness
Hardness yog qhov ntsuas ntawm qhov nyuaj lossis muag cov khoom siv hlau.Nyob rau hauv lub neej no nyob rau hauv zus tau tej cov hardness ntsuas txoj kev yog feem ntau siv nyob rau hauv lub indenter hardness txoj kev, nws yog siv ib tug tej yam geometric duab ntawm lub taub hau indenter nyob rau hauv ib tug tej yam load rau saum npoo ntawm cov khoom hlau yuav tsum tau kuaj, raws li zoo raws li qhov degree ntawm indenter los txiav txim qhov hardness tus nqi.

Cov kev siv feem ntau yog Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) thiab Vickers hardness (HV) thiab lwm txoj kev.

3. Kev qaug zog
Lub zog, plasticity thiab hardness yog cov cim qhia ntawm cov khoom siv hluav taws xob ntawm cov hlau hauv qab cov khoom zoo li qub.Qhov tseeb, ntau lub tshuab ua haujlwm tau ua haujlwm nyob rau hauv lub voj voog, thiab qaug zog tuaj yeem tshwm sim nyob rau hauv cov xwm txheej no.Txoj kev kuj yuav tsum muaj lwm seem zoo li tshwj xeeb-puab steel yeeb nkab.

Cov dej tsis tshua muaj siab thauj welded steel yeeb nkab (GB / T3092-1993) tseem hu ua cov yeeb nkab dav dav, feem ntau hu ua cov yeeb nkab dub.Nws yog welded steel yeeb nkab siv rau kev xa dej, roj, huab cua, roj, cua sov chav thiab lwm yam dej siab thiab lwm yam.Cov phab ntsa tuab ntawm cov yeeb nkab steel yog muab faib ua cov yeeb nkab steel zoo tib yam thiab cov yeeb nkab tuab tuab.Daim ntawv kawg ntawm cov yeeb nkab yog muab faib ua cov hlau tsis-rebar steel raj (lub teeb raj) thiab nrog rebar steel raj.Steel raj specifications qhia los ntawm nominal txoj kab uas hla (mm), uas yog ib qho approximation ntawm lub puab kab.Nws yog kev cai siv ntiv tes, xws li 11/2.Cov welded steel yeeb nkab siv rau kev thauj mus los tsis tshua muaj siab yog siv los ua cov yeeb nkab qub ntawm galvanized welded steel yeeb nkab siv rau kev thauj mus los tsis tshua muaj siab.

Galvanized welded steel yeeb nkab rau kev thauj mus los tsis tshua muaj siab (GB / T3091-1993) tseem hu ua galvanized fais welded steel yeeb nkab, feem ntau hu ua cov yeeb nkab dawb.Nws yog ib qho kub dip galvanized welded (lub qhov cub vuam lossis hluav taws xob vuam) steel yeeb nkab siv rau kev xa dej, roj, roj cua, cua sov chav, dej sov thiab lwm yam dej tsis tshua muaj siab lossis lwm lub hom phiaj.Cov phab ntsa tuab ntawm cov yeeb nkab steel yog muab faib ua cov yeeb nkab zoo tib yam galvanized steel yeeb nkab thiab tuab galvanized steel yeeb nkab.Qhov kawg ntawm cov yeeb nkab yog muab faib ua galvanized steel yeeb nkab tsis muaj xov thiab galvanized steel yeeb nkab nrog xov.

Cov pa roj carbon steel hlau bushing (GB3640-88) yog siv los tiv thaiv cov hlau hauv cov tsev lag luam thiab pej xeem, kev teeb tsa tshuab thiab khoom siv thiab lwm yam kev teeb tsa hluav taws xob.

Ncaj seam fais welded steel yeeb nkab (YB242-63) yog cov yeeb nkab steel nrog longitudinally parallel welds.Feem ntau muab faib ua metric welded steel yeeb nkab, welded nyias-phab ntsa yeeb nkab, transformer txias tubing thiab hais txog.

Kauv seam submerged arc welded steel yeeb nkab (SY5036-83) rau kev thauj mus los ntawm cov kua dej siab yog ib qho kauv seam steel yeeb nkab, uas yog ua los ntawm kub dov steel sawb raws li lub raj dawb paug, feem ntau tsim los ntawm sov kub thiab welded los ntawm ob sab submerged arc vuam txoj kev. .Cov yeeb nkab steel muaj qhov muaj peev xwm ua tau zoo thiab kev ua haujlwm vuam zoo.Nws muaj kev nyab xeeb thiab txhim khu kev qha siv tom qab txhua yam kev soj ntsuam nruj thiab kev sim.Loj txoj kab uas hla steel yeeb nkab, siab kis tau tus mob efficiency, thiab yuav txuag tau lub peev ntawm pipeline tso.Feem ntau yog siv rau kev xa cov roj thiab cov kav dej ntuj.

seamless square steel tubing Zoo li feem ntau tsis-stainless steels, nws tuaj yeem hardened los ntawm "quenching thiab tempering" kev kho cua sov.Nws muaj tsawg kawg yog 11.5% chromium, txaus los muab kev tiv thaiv corrosion.Thaum nws

Qhov siab tshaj plaws corrosion kuj yog tiav thaum hardened thiab tempered thiab ces polished.Chav Kawm 409 yog cov hom phiaj dav dav feem ntau muab rau hauv cov tawv tawv tab sis tseem ua haujlwm tau rau cov ntawv thov uas xav tau lub zog siab thiab nruab nrab kub thiab corrosion kuj.
