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 ka paipu maʻemaʻe ʻole no ka hale (GB/T14975-2002) he paipu wela (extruded, hoʻonui) a me ke anu (rolled) seamless paipu i hana ʻia me ke kila kila i hoʻohana ʻia i ka kemika, ka aila, textile, lāʻau lapaʻau, meaʻai, mīkini a me nā ʻoihana ʻē aʻe, nā paipu kūpaʻa-corrosion a me nā ʻāpana a me nā ʻāpana.

ʻO GB/T8162-2008 (paipu maʻemaʻe no ka hale) ua hoʻohana nui ʻia no ka hana maʻamau a me ka mechanical structure.Its representative material (brand): carbon steel 20, 45 steel, Q235, alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo , 42CrMo a pela 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 i hukiia (owili) seamless kila paipu elua ano. ʻano.

A.Overview o kaʻina kahe

ʻO ka ʻōwili wela (hoʻoheheʻe ʻia ka paipu kila liʻiliʻi): puʻupuʻu pōʻai billet → hoʻomehana → perforation → ʻekolu ʻōwili keʻa, 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 ʻana i ke kaomi wai (a i ʻole hemahema. ʻike) → māka → mālama.

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