Nui-anawaena LSAW kila paipu kaʻina hana nui wehewehe:
1. paʻa pā: hoʻohana 'ia e hana nui anawaena submerged arc welded kila paipu ami pololei ma hope o ke komo 'ana i ka hana laina, ka mua piha-papa kani ultrasonic ho'āʻo;

2. Milling: Milling machine ma ka ʻaoʻao ʻelua ʻaoʻao o ka pā wili, i mea e hoʻokō ai i nā koi o ka laula pā, ua like nā ʻaoʻao pā i ke ʻano o ke ʻano a me ke degere;

3. ʻO ka ʻaoʻao pre-curved: ka hoʻohana ʻana i ka mīkini pre-bending plate pre-bending plate lihi, pono ka lihi o ka pā i nā koi o ka curvature;

4. Hoʻokumu: i ka hapa mua o ka mīkini hoʻoheheʻe JCO ma hope o ke kuʻi mua ʻana ma hope o kekahi mau kila i hoʻopaʻa ʻia, paʻi ʻia i loko o kahi ʻano "J", a laila ʻo ka hapa ʻē aʻe o ka pā kila like ʻole, kaomi i ke ʻano "C". , e hana ana i ka wehe hope ʻO ke ʻano "O".

5. Pre-weld: e hana i kahi paipu kila i hoʻopaʻa ʻia ma hope o ka hana ʻana a me ka hoʻohana ʻana i ke kinoea welding seam (MAG) no ka hoʻomau mau ʻana;

6. Iloko o ka weld: he tandem multi-wire submerged arc wili (a hiki i eha uea) ma ka loko pololei humuhumu kila paipu;

7. Mawaho weld: he tandem multi-wire submerged arc kuʻihao ma waho LSAW wili paipu kila;

8. Kani ultrasonic ho'āʻo: i loko a ma waho o ka pololei seam welded kila paipu weld a weld aoao elua o ka mea kumu 100% inspection;

9. Nānā X Ray: 100% weld ma loko a ma waho o ka X-ray industrial TV nānā me ka hoʻohana ʻana i ka ʻōnaehana kiʻi kiʻi e hōʻoia i ka ʻike ʻike;

10. Expansion:No ka submerged arc kuʻihao a pololei seam kila paipu lōʻihi puka anawaena i mea e hoʻomaikaʻi i ka nui precision o ke kila paipu, a hoʻomaikaʻi i ka mahele ana i ke kaumaha i loko o ke kila paipu;

11. Ho'āʻo Hydraulic: Ma ka mīkini ho'āʻo hydraulic no ke kila ma hope o ka hoʻonuiʻana i ka ho'āʻo o ke aʻa e hōʻoia i ka paipu kila e ho'āʻo i nā koi koi o ka maʻamau, ua loaʻa i ka mīkini kahi hoʻopaʻa hoʻopaʻa a me ka mālama pono;

12. Chamfering: ka nānā 'ana i ka paipu kila ma hope o ka pau 'ana o ka hana 'ana i ka paipu hopena beveling nui koi.
