SSAW Pipe kila

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 pipe and one for longitudinal submerged arc welded steel pipe, are respectively comprised of two sets of main machines and 1 set of sizing equipment.

1. Coil Probe: ke kila kila i loko o ka laina hana, ka papa mua piha Ultrasonic Inspection
2. Leveling Milling: ma o anvil plate leveling machine i hiki ai i ka curl kumu, a laila e hele i nā ʻaoʻao ʻelua o ke kila ʻaoʻao wili mīkini wili, i hiki i nā koi o ka laula pā, plate lihi parallel groove shape
3. ʻAno ʻoki: laina hana kila ma ka ʻaoʻao o waho o ka paipu coiled-coil
4. welding and cutting: the use of advanced technology for pre double submerged arc welding(dsaw) cutting inside from the foot of the welding specification welded steel pipe welded outside use, etc.
5. Nānā ʻike maka: kekahi mau ʻāpana kumu e ka nānā ʻenehana loea
6. ultrasonic flaw: nā ʻaoʻao o loko a me waho o ke kumu metala a weld seam 100% nānā.
7. ʻIke X-ray: nā welds i loko a me waho 100% nā mākaʻikaʻi ʻoihana kīwī X-ray, ʻo ka hoʻohana ʻana i ka ʻōnaehana kiʻi e hōʻoia i ka ʻike ʻike.
8. Pressure test: hydrostatic ikea ai machine by-root test steel pipe up to the standard requirements to ensure that the test pressure
9. Chamfer pae: kila paipu inspection paipu hopena, a hiki i na koi o ka paipu hopena beveling nui
10. Check: X-rays and then subjected to ultrasonic hoʻokolohua and magnetic particle inspection conducted pipe end, check whether the deposit welding problems and defects in the pipe ends.
11. Oiled Marking: ʻO kaʻaila maikaʻi maikaʻi i ka paipu kila a e like me nā koi o ka mea hoʻohana no ka hōʻailona.
