SEAMLESS STEEL TUBES RAU LOW thiab nruab nrab siab boilers (GB3087-2008) yog kub-kuav los tiag thiab txias-draw seamless steel hlab ua los ntawm zoo carbon structural steel rau ntau yam qauv ntawm qis thiab nruab nrab siab boiler superheated chav tubes, boiling dej raj. thiab locomotive boiler superheated steam tubes, cov pa luam yeeb loj, cov pa luam yeeb me me thiab cov hlab cib.Cov khoom sawv cev rau 10,20 steel.

Seamless steel tubes (GB6479-2000) rau cov khoom siv tshuaj lom neeg siab yog cov khoom siv zoo carbon steel thiab hlau alloy steel seamless steel raj tsim rau cov khoom siv tshuaj thiab cov kav dej nrog kev ua haujlwm kub ntawm -40 ~ 400 ° C thiab ua haujlwm siab ntawm 10 ~ 30 ma .Cov khoom siv sawv cev rau 20,16MN, 12CrMo, 12Cr2Mo thiab lwm yam.6. SEAMLESS STEEL TUBES FOR PETROLEUM CRACKING (GB9948-2006).Cov qauv siv hluav taws xob feem ntau yog siv rau boilers, kub exchangers thiab pipelines conveying kua nyob rau hauv roj av smelters.Nws cov khoom sawv cev yog 20,12CRMO, 1Cr5Mo, 1Cr19Ni11Nb thiab lwm yam.Tua.Cov yeeb nkab steel rau geological drilling (YB235-70) yog ib hom hlau yeeb nkab rau cov tub ntxhais drilling, uas tuaj yeem muab faib ua cov yeeb nkab laum, laum dab tshos, tub ntxhais yeeb nkab, cov yeeb nkab thiab cov yeeb nkab.8. Seamless steel yeeb nkab (GB3423-82) rau pob zeb diamond tub ntxhais drilling yog seamless steel yeeb nkab rau laum yeeb nkab, tub ntxhais pas nrig thiab casing.9. Cov roj drilling yeeb nkab (YB528-65) yog seamless steel yeeb nkab uas yog siv los ua kom tuab sab hauv lossis sab nraud ntawm ob kawg ntawm cov roj drilling yeeb nkab.Cov yeeb nkab steel tau muab faib ua ob hom: xaim xaim thiab tsis xaim xaim.Cov xaim xaim xaim yog txuas nrog kev sib koom ua ke, thiab cov yeeb nkab tsis xaim xaim txuas nrog lub cuab yeej sib koom ua ke los ntawm pob tw vuam.10. Carbon thiab carbon manganese steel seamless steel raj rau nkoj (GB / t 5312-2009) yog tsim rau kev tsim cov marine qib I, II, boiler thiab superheater carbon thiab carbon manganese steel seamless steel hlab.Seamless steel raj rau siab piping system muab faib ua 3 qib raws li kev tsim siab thiab tsim kub.Kev ua haujlwm kub ntawm seamless steel raj phab ntsa rau boiler thiab superheater yuav tsum tsis pub tshaj 450 ° C.526/2000

Tua.Seamless Steel Tube (GB3088-82) rau tsheb qag ncej tes tsho yog ib hom zoo carbon structural steel thiab alloy structural steel kub dov seamless steel raj rau tsheb qag ncej tes tsho thiab tsav qag tsev axle ncej raj.12. Cov yeeb nkab roj siab siab rau lub cav diesel (GB3093-86) yog cov yeeb nkab txias seamless steel yeeb nkab rau kev tsim cov yeeb nkab siab ntawm lub cav diesel.13. Precise puab txoj kab uas hla seamless steel raj (GB8713-88) rau hydraulic thiab pneumatic thooj voos kheej kheej yog txias-draw los yog txias-dov precision seamless steel raj nrog meej puab txoj kab uas hla qhov ntev rau kev tsim cov hydraulic thiab pneumatic thooj voos kheej kheej.14. Cold-drawn los yog txias-dov precision seamless steel hlab (GB3639-83) yog txias-draw los yog txias-dov precision seamless steel hlab nrog siab qhov tseeb thiab zoo nto tiav rau cov khoom siv tshuab, cov khoom siv hydraulic.Qhov kev xaiv ntawm precision seamless steel yeeb nkab tsim cov qauv siv tshuab lossis cov khoom siv hydraulic, tuaj yeem txuag lub sijhawm ua haujlwm zoo, txhim kho cov khoom siv, thiab pab txhim kho cov khoom zoo.
