ASTM A53 Welded Steel Pipe yog dab tsi?
ASTM A53yog tus qauv tsim los ntawm American Society for Testing and Materials (ASTM International), npog seamless steel yeeb nkab (Type S), tsis kam welded steel yeeb nkab (Type E), thiab rauv welded steel yeeb nkab (Type F). Tsis kam vuam (ERW) thiab laser submerged arc vuam (LSAW) yog tam sim no feem ntau siv vuam txheej txheem.
1, Daim Ntawv Thov: Piping rau kev xa cov chav dej, dej, roj, thiab cua, nrog rau kev siv tshuab thiab cov qauv siv.
2, Hom Qib: Qib A thiab Qib B (Qib B muaj zog dua thiab siv dav dua hauv kev siv tshuab).
3, Qhov Loj: Nominal txoj kab uas hla (NPS) 1/8 txog 26 ntiv tes, phab ntsa tuab qib ua raws li Teem caij 10, 40, 80, thiab lwm yam.
Tsib Kev Siv Khoom Loj ntawm ASTM A53 Welded Steel Pipe
1. Kev thauj mus los ntawm cov kav dej thiab roj
Daim ntawv thov: Cov kav dej xa dej, cov kav dej nkev, cua sov, qhov cua, thiab cua txias (HVAC) cov kav dej, cov kav dej.
Qhov zoo: ERW txheej txheem ua kom ruaj khov welds, haum rau cov kua nruab nrab mus rau qis.LSAW processenables zus tau tej cov loj- txoj kab uas hla, tuab-walled kav kom tau raws li kev xav tau kev thauj mus los ntawm lub nroog thiab lub zog tej yaam num.
2. Kev txhawb nqa kev tsim thiab kev tsim kho
Daim ntawv thov: Steel structural thav duab, Hoobkas kem, choj kev txhawb nqa, scaffolding.
Qhov zoo:A53 welded steel yeeb nkabtuaj yeem welded thiab khoov, ua kom yooj yim rau ntawm -site installation.Welded steel yeeb nkab yog kev lag luam ntau dua li seamless steel yeeb nkab, txo cov nqi tsim nyog.
3. Machinery Manufacturing
Daim ntawv thov: Agricultural machinery, automotive qhov chaw, tsav shafts, kev tsim kho machinery txhawb caj npab.
Qhov zoo: Standardized yeeb nkab qhov ntev pab txhawb kev machining.Grade B muaj zog dua, haum rau cov kabmob nruab nrab cov khoom siv.
4. Zog thiab Industrial Engineering
Daim Ntawv Thov: Fais fab nroj tsuag condensate kav, petrochemical cog qis - cov kav xa hluav taws xob siab, mine qhov cua ducts.
Qhov zoo: ERW yog qhov tsim nyog rau cov txheej txheem cov kav dej;LSAWtuaj yeem ua tau raws li qhov loj - txoj kab uas hla ntawm loj - cov phiaj xwm hluav taws xob loj.
5. Cov Txheej Txheem Hluav Taws Xob
Daim ntawv thov: Tsis siv neeg lub tshuab sprinkler, hluav taws kub hydrant tes hauj lwm, hluav taws kub risers.
Qhov zoo:A53 steel kavtuaj yeem ua galvanized los txhim kho corrosion kuj thiab txuas ntxiv kev pab cuam lub neej.Lawv ua tau raws li qhov yuav tsum tau muaj ntawm nruab nrab - cov kav dej siab hauv hluav taws xob tiv thaiv engineering thiab muab cov nqi siab - ua tau zoo.
