EN10219 LSAW Structure Pipe

 

EN10219 European tus qauv muab cov ncauj lus qhia ntxaws ntxaws rau cov txheej txheem txias-tsim welded kev xav tau ntawm cov voj voog, square, thiab lub voj voos hollow, siv tau rau qhov txias-tsim lossis tsis tau ua tiav hollow seem.

Cold forming: Cov txheej txheem shaping nqa tawm ntawm chav tsev kub yog hu ua txias forming.
Normalized Rolling: Rolling yuav tsum tau ua ntawm qhov kub thiab txias, thiab cov cuab yeej tshwj xeeb yuav tsum tau tswj xyuas tom qab normalization.
Kub Rolling: Rolling yuav tsum tau ua ntawm qhov kub thiab txias tab sis yuav tsum tsis txhob ncav cuag qhov kub thiab txias rau kev kho cua sov. Ua kom kub siab tshaj 580 degree yuav txo tau nws lub zog.
Nco tseg: Kub dov ua rau kev xa khoom M tuaj yeem suav nrog tempering lossis semi-tempering thaum lub sijhawm tsim khoom, tab sis tsis suav nrog quenching, quenching thiab tempering.

Kev tshuaj xyuas ntawm EN10219 LSAW Pipe

• Kev tshuaj xyuas thiab kuaj hom

1 Rau cov seem uas tsis yog-alloy hollow ntawm cov qib JR thiab JO, cov kev xeem tsis tshwj xeeb yuav tsum ua raws li EN10021 tus qauv tshwj tsis yog tus neeg siv khoom muab cov ncauj lus kom ntxaws thaum lub sijhawm xaj. Cov neeg siv khoom tuaj yeem txheeb xyuas cov kev xav tau thiab kuaj thaum tso lawv cov xaj.

2 Rau cov seem uas tsis yog-alloy hollow ntawm qib zoo J2 thiab zoo-grain steel zoo N, M, ML, thiab NL, cov kev xeem yuav tsum ua raws li EN10021 tus qauv.

• Hom Cov ntaub ntawv tshuaj xyuas

1 Cov ntaub ntawv soj ntsuam tsis tshwj xeeb rau cov khoom yuav tsum ua raws li EN10204 tus qauv. Cov coding thiab cov ntaub ntawv muaj feem xyuam nrog rau hauv cov ntaub ntawv soj ntsuam yuav tsum ua raws li cov cai ntawm EU tus qauv 168.

- A: Kev lag luam
- B: Cov khoom piav qhia hauv daim ntawv tshuaj ntsuam xyuas
- C: Cov ntaub ntawv soj ntsuam raws li hauv qab no:
- C11-C13: Daim ntawv qhia txog Tensile
- C71-C92: Daim ntawv qhia ua ntej lub cub tawg
- Z: Daim ntawv pov thawj ntawm daim ntawv tshuaj ntsuam xyuas.

2 Daim ntawv pov thawj kev tshuaj xyuas lossis cov ntawv tshaj tawm tshuaj xyuas rau cov khoom lag luam uas yuav tsum tau kuaj xyuas tshwj xeeb yuav tsum tau muab ua raws li EN10204 tus qauv.
