Taw qhia
Cov kav dej siv tau siv dav hauv kev lag luam, los ntawm kev tsim kho mus rau roj thiab roj. Lawv paub txog lawv cov durability, lub zog, thiab versatility. Hauv tsab xov xwm no, peb yuav ua tib zoo saib ntawm cov kav dej, nrog rau lawv cov khoom, qib, thiab kev siv.
Structural Pipes yog dab tsi?
Cov kav dej muaj zog yog cov raj hollow ua los ntawm cov khoom siv xws li steel, aluminium, lossis yas. Lawv yog tsim los tiv thaiv hnyav loads thiab siab, ua rau lawv zoo tagnrho rau siv nyob rau hauv cov qauv kev siv uas yuav tsum tau muaj zog thiab durability.
Cov kav dej muaj ntau yam duab thiab ntau thiab tsawg, los ntawm square thiab rectangular mus rau puag ncig thiab oval. Lawv tuaj yeem welded los yog seamless, nyob ntawm seb qhov kev siv.
Cov yam ntxwv ntawm cov kav dej muaj zog
Cov yam ntxwv ntawm cov kav dej sib txawv nyob ntawm cov khoom siv. Txawm li cas los xij, qee qhov khoom siv dav dav suav nrog:
- Lub zog: Cov kav dej tsim tau paub txog lawv lub zog siab thiab muaj peev xwm thauj khoom.
- Durability: Lawv tau tsim los tiv thaiv kev siv hnyav thiab raug rau cov khoom.
- Versatility: Cov kav dej muaj peev xwm siv tau rau ntau yam kev siv, los ntawm kev txhawb nqa cov tsev mus rau nqa cov kua dej thiab roj.
- Corrosion resistance: Nyob ntawm cov khoom siv, cov kav dej muaj zog tuaj yeem tiv taus corrosion thiab xeb.
Qib yeeb yam qauv
Cov kav dej tsim tau raug ntsuas raws li lawv lub zog thiab lwm yam khoom. Cov qib feem ntau siv hauv kev siv cov qauv muaj xws li:
- ASTM A500 Qib B: Qhov no yog ib qho kev qhia tshwj xeeb rau txias-tsim welded thiab seamless carbon steel structural tubing nyob rau hauv round, square, thiab rectangular duab. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 46, 000 psi thiab lub zog tensile yam tsawg kawg nkaus ntawm 58, 000 psi.
- ASTM A53 Qib B: Qhov no yog tus qauv tshwj xeeb rau seamless thiab welded dub thiab kub-dipped galvanized steel yeeb nkab hauv NPS 1/8 txog NPS 26 [DN 6 txog DN 650]. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 35, 000 psi thiab lub zog tensile yam tsawg kawg nkaus ntawm 60, 000 psi.
- ASTM A106 Qib B: Qhov no yog tus qauv tshwj xeeb rau seamless carbon steel yeeb nkab rau kev pabcuam kub. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 35, 000 psi thiab lub zog tensile yam tsawg kawg nkaus ntawm 60, 000 psi.
- API 5L Qib B: Qhov no yog qhov tshwj xeeb rau kab yeeb nkab. Nws muaj qhov tsawg kawg nkaus lub zog ntawm 35, 000 psi thiab lub zog tensile yam tsawg kawg nkaus ntawm 60, 000 psi.
Kev siv cov kav dej muaj zog
Cov kav dej tsim muaj ntau yam kev siv hauv ntau yam kev lag luam, suav nrog:
- Kev tsim kho: Cov kav dej siv tau siv rau hauv kev tsim vaj tsev, txuas hniav, thiab lwm yam khoom siv. Lawv muab kev txhawb nqa thiab kev ruaj ntseg, tshwj xeeb tshaj yog nyob rau hauv cov tsev siab.
- Roj thiab roj: Cov kav dej muaj zog yog siv rau hauv kev lag luam roj thiab roj rau kev thauj cov roj thiab roj mus ntev. Lawv kuj tseem siv rau kev ua haujlwm drilling thiab ntau lawm.
- Kev Ua Liaj Ua Teb: Cov kav dej tsim qauv siv rau hauv kev lag luam ua liaj ua teb rau kev siv dej, tsiaj vaj tsev, thiab lwm yam kev siv.
- Kev tsim khoom: Cov kav dej siv tau siv hauv kev tsim khoom rau kev siv tshuab, kev tuav cov khoom siv, thiab lwm yam kev siv.
