API SSAW Loj Diameter Kauv Welded Steel Pipe

API-5L welded kauv steel yeeb nkab yog tsim los ntawm kub-kuav los tiag strip steel los yog steel phaj, siv lub tshuab tsim los yob cov sawb hlau los yog steel phaj rau hauv ib puag ncig los yog tshwj xeeb-zoo li tus steel yeeb nkab. Tom qab ntawd nws yog welded siv lub tshuab welding high-frequency. API-5L (American Petroleum Institute) kauv kav raws li tus qauv no feem ntau yog siv rau kev tsim cov kav dej thiab tau muab faib ua qib 1 thiab 2 raws li daim ntawv thov. API kauv cov kav dej muaj kev tiv thaiv corrosion zoo heev thiab lub zog siab, ua rau lawv tsim nyog rau kev thauj mus los ntev roj thiab roj nrog rau kev xa mus rau hauv nroog.

Qhov zoo thiab qhov tsis zoo ntawm API Loj-inch Kauv Welded Pipe

1. Nyob rau hauv tib lub siab, qhov kev ntxhov siab los ntawm API kauv weld seam yog 75% mus rau 90% ntawm qhov ncaj seam, cia nws tiv taus siab dua. Piv nrog cov seam ncaj welded kav ntawm tib txoj kab uas hla, phab ntsa thickness yuav txo tau los ntawm 10% mus rau 25% nyob rau hauv tib lub siab.

2. Qhov ntev yog qhov tseeb, nrog rau txoj kab uas hla feem ntau tsis tshaj 0.12%, deflection tsawg dua 1/2000, thiab ovality tsawg dua 1%. Qhov no feem ntau tshem tawm qhov xav tau ntawm qhov loj me thiab cov txheej txheem ncaj.

3. Nruam ntau lawm yog ua tau, theoretically tsim infinitely ntev steel kav, nrog tsawg tsawg los ntawm kev txiav xaus. Qhov no tuaj yeem txhim kho kev siv hlau los ntawm 6% mus rau 8%.

4. Muab piv rau cov kav dej ncaj seam welded, nws muaj kev ua haujlwm yooj yim thiab yooj yim ntawm kev hloov thiab kho ntau yam.

5. Cov khoom siv yog lub teeb yuag thiab yuav tsum tau pib nqis peev tsawg. Nws tuaj yeem ua rau hauv lub tsheb thauj khoom-mounted mobile, tsim cov kav dej ncaj qha ntawm qhov chaw tsim kho kav dej.

6. Nws yog ib qho yooj yim mus cuag mechanization thiab automation.

Qhov tsis zoo ntawm API Loj-inch Kauv Welded Pipe:

Vim yog kev siv cov coiled sawb hlau ua raw khoom, muaj qee yam ntawm crescent dabtsi yog khoov, thiab vuam taw tes yog nyob rau ntawm elastic strip steel ntug cheeb tsam, ua rau nws nyuaj rau welding torch, yog li cuam tshuam rau vuam zoo. Yog li ntawd, txoj kev weld seam taug qab thiab cov cuab yeej tshuaj xyuas zoo yuav tsum tau teeb tsa.
