ASTM steel yeeb nkab yog hais txog carbon steel yeeb nkab siv nyob rau hauv cov roj thiab roj kis tau tus mob. Nws kuj tseem siv los thauj lwm cov kua dej xws li chav dej, dej, thiab av nkos.

Hom kev tsim khoom

ASTM STEEL PIPE specification npog ob qho tib si welded thiab seamless fabrication hom.

Welded Hom: ERW, SAW, DSAW, LSAW, SSAW, HSAW Pipe

Hom ASTM welded yeeb nkab yog raws li nram no:

ERW: Hluav taws xob tiv thaiv vuam, feem ntau yog siv rau cov yeeb nkab diameters tsawg dua 24 ntiv tes.

DSAW/SAW: Ob chav sided submerged arc vuam / submerged arc vuam, lwm txoj kev vuam rau ERW siv rau cov kav dej loj dua.

LSAW: Longitudinal submerged arc vuam, siv rau cov yeeb nkab diameters txog 48 ntiv tes. Kuj tseem hu ua JCOE fabrication process.

SSAW/HSAW: Kauv submerged arc vuam / kauv submerged arc vuam, siv rau cov yeeb nkab diameters txog 100 ntiv tes.

Tiv tauj peb kom paub qhov txawv ntawm ERW, LSAW, thiab SSAW yeeb nkab.

Seamless yeeb nkab hom: Kub dov Seamless yeeb nkab thiab txias dov Seamless yeeb nkab

Seamless yeeb nkab feem ntau yog siv rau cov kav dej me me (feem ntau tsawg dua 24 ntiv tes).

(Seamless steel yeeb nkab yog feem ntau siv tshaj welded yeeb nkab rau cov yeeb nkab diameters tsawg dua 150 hli (6 nti).

Peb kuj muab txoj kab uas hla loj seamless yeeb nkab. Siv cov txheej txheem kub dov, peb tuaj yeem tsim cov yeeb nkab seamless mus txog 20 nti (508 mm) inch. Yog tias koj xav tau seamless yeeb nkab loj dua 20 ntiv tes hauv txoj kab uas hla, peb tuaj yeem tsim nws siv cov txheej txheem kub nthuav dav txog 40 ntiv tes (1016 hli) inch.

Ntim thiab thauj

Ntim yogfeem ntau liab qab, steel hlau khi, heevmuaj zog.
Yog tias koj muaj cov cai tshwj xeeb, koj tuaj yeem sivxeb pov thawj ntim, thiab zoo nkauj dua.

Kev ceev faj rau kev ntim khoom thiab kev thauj mus los ntawm cov pa roj carbon steel kav
1.astm steel yeeb nkab yuav tsum tau tiv thaiv los ntawm kev puas tsuaj los ntawm kev sib tsoo, extrusion thiab txiav thaum thauj, khaws cia thiab siv.
2. Thaum siv cov yeeb nkab carbon steel, koj yuav tsum ua raws li cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm thiab ua tib zoo saib xyuas kom tsis txhob tawg, hluav taws kub, tshuaj lom thiab lwm yam xwm txheej.
3. Thaum siv, astm steel yeeb nkab yuav tsum tsis txhob sib cuag nrog cov kub kub, corrosive media, thiab lwm yam. Yog hais tias siv nyob rau hauv cov cheeb tsam no, carbon steel yeeb nkab ua los ntawm cov ntaub ntawv tshwj xeeb xws li kub tsis kam thiab corrosion kuj yuav tsum tau xaiv.
4. Thaum xaiv cov pa roj carbon steel kav, cov pa roj carbon steel kav ntawm cov khoom tsim nyog thiab cov lus qhia tshwj xeeb yuav tsum tau xaiv raws li kev xav tau zoo xws li kev siv ib puag ncig, nruab nrab cov khoom, siab, kub thiab lwm yam.
5. Ua ntej siv cov pa roj carbon steel kav, kev tshuaj xyuas thiab kev ntsuam xyuas yuav tsum tau ua los xyuas kom meej tias lawv cov khoom ua tau raws li qhov yuav tsum tau ua.
