ʻAno hoʻāʻo ʻana i ka paipu kila maʻemaʻe:

ʻO ka hoʻāʻo ʻana i ka paipu kila maʻemaʻe ʻole i ʻōwili ʻia: me ka paipu kila maʻamau, haʻahaʻa a me ka haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa ka paila kila paipu, kiʻekiʻe kiʻekiʻe o ka paila kila paipu, ka paipu kila hoʻohuihui, ka paipu kila kuhiliʻi, ka ʻaila māhā paipu, ka paipu kila geological a me nā hoʻāʻo ʻana i ka hoʻāʻo ʻana. .

ʻO ka sela ceelle cheelless chery Colled roolless Seelless Sweelless Seelleding, Mechanical Community Creakless, High Builless Butless Builless Booce wili honua, wili paipu, hydraulic cylinder cylinder precision inner diameter seamless pipe, seamless tube for fertilizer, he moku me ka paipu, aila mawae paipu, kela ano keia ano o na ano a pau o ke anu anu i olokaa seamless paipu kila e like me ka ike.

He paipu kila maʻemaʻe ʻole a puni ka hoʻoheheʻe ʻia ʻana o ke kila: ʻaila hoʻoheheʻe ʻana i ka ʻili, ʻo ka ʻili ʻili o ka petrochemical, paipu paila, paipu halihali a me nā kaʻa, tractor, aviation high-precision structural steel tube hoʻāʻo.

ʻO ka hoʻāʻo ʻana o ka paipu kila maʻemaʻe: ʻo ka paipu kila kuhili ʻole i ʻōwili ʻia, ka paipu kila kuhili ʻole extrusion a me ka paipu kila kuhili ʻole i huki ʻia (rolled), semi-ferritic semi-Martensitic paipu kila kila, martensitic stainless steel pipe, austenitic stainless steel pipe, austenite-ferritic hao. ʻōnaehana paipu kila kila, etc.

ʻO ka ʻike ʻana o ka paipu maʻemaʻe ʻole: ʻike ʻia ka ʻike ʻana o ke koena o ka ea, ke kaulike wai lepo a me ke kaulike o ka honua.

ʻO ka hoʻāʻo ʻana i nā paipu kila maʻemaʻe like ʻole: e like me ka huinahā, oval, triangle, hexagonal, melon shape, hōkū ʻano, a me nā ʻēheu seamless steel tubes.

ʻO ka paipu kila maʻemaʻe ka hoʻāʻo ʻana: paipu kila mānoanoa i ʻōwili ʻia i ka paia mānoanoa, ʻo ka paipu kila maʻemaʻe ʻole o ka paia, ʻo ka paipu kila maʻemaʻe ʻole o ka paia, ka paipu kila maʻemaʻe ʻole, ke kila mānoanoa i hoʻokuʻu ʻia. paipu jacking structure, etc.

ʻO ka hoʻāʻo ʻana i ka paipu kila maʻemaʻe: me ka paipu kila maʻamau, haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa o ka paila kila paipu, kiʻekiʻe kiʻekiʻe o ka paila kila paipu, ka paipu kila kila, ka paipu kila kuhiliʻole, ka ʻaila māwae, ka paipu kila geological a me nā paipu kila ʻē aʻe.

Nā mea ho'āʻo paipu kila ʻole:

Ke ho'āʻo nei nā waiwai kemika i ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa haʻahaʻa haʻahaʻa, ka pale ʻana i ka waika, ka pale ʻana i ka alkali, ke kūpaʻa ʻana, etc.

Kaʻina hana hoʻāʻo uea hoʻopololei, ʻike haʻihaʻi, kulou mau ʻana, hoʻohuli ʻia, hoʻohuli hoʻopalapala, ʻelua ʻaoʻao torsion, hydraulic test, flaring test, bending, crimping, flattening, hoʻonui apo, apo kikoʻī, microstructure, hoʻāʻo kīʻaha kīʻaha, metallographic analysis, etc.

ʻO ka hoʻāʻo nondestructive X - ray nondestructive hoʻāʻo, electromagnetic ultrasonic testing, ultrasonic testing, eddy current testing, magnetic flux leakage testing, penetration testing, magnetic particle testing.

Ho'āʻo nā waiwai mīkini i ka ikaika tensile, hoʻāʻo hopena, wahi hua, elongation ma hope o ka haʻihaʻi ʻana, hoʻemi ʻāpana, ʻano paʻakikī (Rockwell hardness, Brinell hardness, Vickers hardness, Richter hardness, Vickers hardness).

ʻO nā mea ʻē aʻe: ka hana metallographic, inclusions, decarburization layer, ka hoʻoholo ʻana i ka ʻike o ka microstructure, ka nānā ʻana i ke kumu corrosion, ka nui o ka palaoa a me ka helu microscopic, ka haʻahaʻa haʻahaʻa, intergranular corrosion, microstructure o superalloy, kiʻekiʻe kiʻekiʻe metallographic structure, etc.

'Ikepili 'ikamu: ka ho'ohālikelike ho'ohālikelike, ka 'ike waiwai, ka hā'ule 'ole, ka 'āpana 'āpana.

ʻO ka nānā ʻana i ka hoʻomaʻamaʻa ʻana i ka haʻihaʻi haʻihaʻi, ka nānā ʻana i ka corrosion, etc.

ʻIke a kālailai pono i ka haku mele a me ka ʻike o ka manganese, oxygen, nitrogen, carbon, sulfur, silicon, iron, aluminum, phosphorus, chromium, vanadium, titanium, copper, cobalt, nickel, molybdenum, cerium, lanthanum, calcium, magnesium , zinc, tin, antimony, arsenic a me nā mea metala ʻē aʻe i ka metala, ka hao a me kāna mau huahana, ke kila kila.

Ho'āʻo maʻamau no ka seamless steel paipu (hapa):

GB 18248-2008 ʻO nā paipu kila ʻole no nā pahu hau.

2, GB / T 18984-2016 seamless kila paipu no ka haʻahaʻa wela pipeline.

3, GB/T 30070-2013 Alloy steel seamless kila paipu no ka lawe kai.

4, GB / T 20409-2018 ʻO nā paipu kila maʻemaʻe me ke kaula i loko no nā paila kiʻekiʻe.

5, GB 28883-2012 composite seamless paipu kila no ke kaomi.

GB 3087-2008 ʻO nā paipu kila maʻemaʻe no nā paila haʻahaʻa haʻahaʻa a me waena.

7, GB/T 34105-2017 ʻO nā paipu kila ʻole no nā hale ʻenekinia waho.

GB 6479-2013 ʻO nā paipu kila maʻemaʻe ʻole no nā mea hoʻomomona kiʻekiʻe.
