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, ka mānoanoa o ka paia 5-25.4mm a me ke kila kila B-X80. ʻElua mau laina hana paipu kila, hoʻokahi no ke arc submerged spiral paipu kila welded a hoʻokahi no ka paipu kila i hoʻoheheʻe ʻia i loko o ke ao holoʻokoʻa, ʻelua pūʻulu o nā mīkini nui a me 1 pūʻulu o nā lako nui.

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.
