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 ka wili honua, ka paipu wili, ka pahu hydraulic cylinder me ka pololei o ke anawaena o loko o ka paipu maʻemaʻe, ka paipu maʻemaʻe no ka mea hoʻomomona, ka moku me ka paipu, ka ʻaila pohā. paipu, nā ʻano like ʻole o nā ʻano mea hoʻoheheʻe anuanu i ʻōwili ʻia i nā ʻili kila ʻole e like me ka ʻike.

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: ʻike ʻia ka ʻike ʻana o ke koena puʻe 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.

ʻO nā mea hoʻāʻo 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 ho'āʻo uea kikoo, fracture inspection, hoomau kulou ana, huli kulou ana, huli hoopalahalaha, elua-ala torsion, hydraulic hoao, flaring hoao, kulou, crimping, palahalaha, apo hoonui, apo kikoo, microstructure, kīʻaha kaʻina ho'āʻo, metallographic kālailai, 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 ho'opau 'ole 'ana, ka ho'opili 'āpana.

ʻO ka hoʻopaʻa ʻana i ka hoʻomaʻamaʻa ʻana i ka hoʻoheheʻe ʻana i ka haʻihaʻi ʻana, 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):
