Hana ʻia ka paipu SSAW me ke kila i ʻōwili ʻia e ka weld arc submerged ma lalo o ka wela o ka lewa maʻamau. Aia he 12 mau hoʻonohonoho o ka laina hana hou o ka paipu SSAW. Ka hua makahiki o ka paipu SSAW me waho anawaena 219mm-

3620mm,wall thickness 5-25.4mm and steel grade B-X80. Its two steel pipe production lines, one for spiral submerged arc paipu kila welded 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. wiliwili a ʻokiʻoki: ka hoʻohana ʻana i ka ʻenehana kiʻekiʻe no ka hoʻohana ʻana i ka ʻenehana mua ʻelua submerged arc welding (dsaw) ʻoki i loko mai ka wāwae o ka kikoʻī kuʻina welded steel pipe welded waho hoʻohana, 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. Paʻi ho'āʻo: hydrostatic ho'āʻo mīkini e-aʻa ho'āʻo kila paipu a hiki i ka maʻamau koi e hōʻoia i ka ho'āʻo kaomi

9. Chamfer pae: kila paipu inspection paipu hopena, a hiki i na koi o ka paipu hopena beveling nui

10. E nānā: X-kukui a laila e ho'āʻo ultrasonic a me ka magnetic particle inspection hoʻopau paipu, e nānā inā pau ka waiho ʻana i nā pilikia a me nā hemahema o ka paipu.

11. Oiled Marking: ʻO kaʻaila maikaʻi maikaʻi i ka paipu kila a e like me nā koi o ka mea hoʻohana no ka hōʻailona.
