SSAW Steel Yeeb Nkab

SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature. There are 12 sets of modernized production line of SSAW pipe. The annual yield of SSAW pipe with outside diameter 219mm-3620mm,wall thickness 5-25.4mm and steel grade B-X80. Its two steel pipe production lines, one for spiral submerged arc welded steel yeeb nkab thiab ib qho rau longitudinal submerged arc welded steel yeeb nkab, feem ntau muaj ob pawg ntawm cov tshuab tseem ceeb thiab 1 txheej ntawm cov khoom siv sizing.

1. Coil sojntsuam: steel kauj rau hauv cov kab ntau lawm, thawj lub rooj tsavxwm Ultrasonic soj ntsuam
2. Leveling milling: los ntawm anvil phaj leveling tshuab kom tus thawj curl, thiab ces dhau ob npoo ntawm steel-sided milling tshuab milling, thiaj li mus txog rau qhov yuav tsum tau ntawm lub phaj dav, phaj ntug parallel zawj duab
3. Txiav Hom: steel ntau lawm kab raws ntug txheej txheej ntawm coiled-coil raj
4. welding and cutting: the use of advanced technology for pre double submerged arc welding(dsaw ua) cutting inside from the foot of the welding specification welded steel pipe welded outside use, etc.
5. Kev tshuaj xyuas qhov muag: qee qhov tsis zoo los ntawm tus kws tshaj lij kev kuaj xyuas
6. ultrasonic flaw: sab hauv thiab sab nraud ntawm lub hauv paus hlau thiab vuam seam 100% tshuaj xyuas
7. X-ray nrhiav pom: sab hauv thiab sab nraud welds 100% X-ray TV kev lag luam kuaj xyuas, kev siv cov duab ua haujlwm kom paub meej qhov kev xav tau
8. Pressure test: hydrostatic kev soj ntsuam machine by-root test steel pipe up to the standard requirements to ensure that the test pressure
9. Chamfer theem: steel yeeb nkab tshuaj xyuas yeeb nkab kawg ua, mus txog qhov yuav tsum tau ntawm cov yeeb nkab kawg beveling loj
10. Check: X-rays and then subjected to kuaj ultrasonic and magnetic particle inspection conducted pipe end, check whether the deposit welding problems and defects in the pipe ends.
11. Oiled Marking: Tsim nyog oiled steel yeeb nkab corrosion thiab ua raws li cov neeg siv yuav tsum tau kos.
