1. Hoʻopuka pōkole o ka paipu hana

Hoʻohana ʻia ka paipu seamless no ka hale (GB / T8162-2008) no ka hoʻolālā maʻamau a me ka ʻōnaehana mechanical o ka paipu maʻemaʻe.

ʻO ke kila kila maʻemaʻe paipu no ka hale (GB / T14975-2002) he paipu wela (extruded, expanded) a me ke anu (rolled) seamless paipu i hana ʻia me ke kila kila i hoʻohana ʻia i ka kemika, ka aila, ka textile, ka lāʻau lapaʻau, ka meaʻai, nā mīkini a me nā ʻoihana ʻē aʻe, corrosion-resistant pipes and structural parts and parts.

ʻO GB / T8162-2008 (paipu maʻemaʻe no ka hoʻolālā) ua hoʻohana nui ʻia no ka hoʻolālā maʻamau a me ka mechanical structure.Its representative material (brand): carbon steel 20, 45 steel, Q235, alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, a pēlā aku.

Paipu kila ʻole

No ka mea o kona manufacturing kaʻina mea okoa, ua maheleia i wela olokaa (extruded) seamless kila paipu a me ke anu huki (owili) seamless kila paipu elua ano.

A.Overview o kaʻina kahe

ʻO ka ʻōwili wela (hoʻoheheʻe ʻia ka pahu kila liʻiliʻi) : puʻupuʻu pōʻai billet → hoʻomehana → perforation → ʻekolu ʻōwili keʻa kaʻa, ʻōwili mau a extrusion paha → ka wehe ʻana o ka paipu → ka hoʻohaʻahaʻa ʻana (a i ʻole ka hoʻohaʻahaʻa ʻana) → hoʻomaʻamaʻa → puʻupuʻu blank → hoʻopololei → hoʻāʻo paʻa wai (a i ʻole ʻike hemahema) → hōʻailona → mālama.

Kiʻi anu (kawili) paipu kila maʻemaʻe: puʻupuʻu pōʻai billet → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → ʻaila ʻaila (kopa keleawe) → kaha kiʻi anuanu (cold rolling) → paipu blank → mālama wela → hoʻopololei → hoʻāʻo ʻana i ka wai (ʻike hewa) → māka → mālama.
