ʻO ka paipu kila maʻemaʻe he ʻano kila lōʻihi me ka ʻāpana ʻāpana a ʻaʻohe hui a puni. ʻO ka paipu kila he ʻāpana hakahaka a hoʻohana nui ʻia no ka lawe ʻana i nā pipeline wai, e like me ka lawe ʻana i ka aila, ke kinoea maoli, ke kinoea, ka wai a me kekahi mau mea paʻa. ʻO ia ke ʻano o ke kila ʻāpana ʻāpana waiwai a hoʻohana nui ʻia i ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me ka paipu ʻaila hinu, ka pahu kaʻa kaʻa, ka pahu kaʻa a me ka scaffolding kila i hoʻohana ʻia i ke kūkulu ʻana.

Ka wā ʻike:

5 mau lā hana ma ka nui loa.

Nā pae hoʻāʻo:

DB, GB, GB/T, JB/T, NB/T, YB/T, etc.

ʻAno hoʻāʻo ʻana i ka paipu kila maʻemaʻe:

Seamless hot rolled seamless steel pipe ho'āʻo: me ka laulā kila paipu, haʻahaʻa a me waena puʻe paila kila paipu, kiʻekiʻe kiʻekiʻe boiler kila paipu, hao hao paipu, kuhiliʻole kila paipu, petroleum mahā paipu, geological kila paipu a me ka wela olokaa seamless paipu paipu.

Paipu kila maʻemaʻe i ʻōwili ʻia me ka hoʻāʻo ʻana: E komo pū me ka hoʻolālā maʻamau, ka hoʻolālā mechanical me ka paipu kila maʻemaʻe, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa paila seamless paipu, kiʻekiʻe kiʻekiʻe ʻo boiler seamless tube, ka wai hoʻouna me ka seamless paipu, huki anu a i ʻole ke anu a pololei pololei o ke kila paipu seamless pipe, geological drilling, drilling pipe, hydraulic cylinder cylinder precision no pipe, seamless pipe seamless pipe. 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 kuhili ʻole i huki ʻia (rolled), semi-ferritic semi-Martensitic stainless steel pipe, martensitic stainless steel pipe, austenitic stainless steel pipe, austenite-ferritic iron system stainless steel pipe, 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.

He paipu kila maʻemaʻe ka hoʻāʻo ʻana: ʻo ka paipu kila mānoanoa i ʻōwili ʻia i ka paia, ʻo ka paipu kila maʻemaʻe ʻole i ka paia, ka paipu kila ʻole o ke kila mānoanoa, ka paipu hao ʻole ka paia mānoanoa i hoʻokuʻu ʻia.

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 waikawa, ka pale ʻana i ka alkali, ke kūpaʻa oxidation, etc.

Kaʻina hana hoʻāʻo uea hoʻolōʻihi ʻia, ka nānā ʻana i ka haʻihaʻi, ka piʻi pinepine ʻana, ka hoʻohuli ʻana i ka hoʻopololei, ka hoʻohuli ʻana i ka pāpaʻi, ʻelua ʻaoʻao torsion, hydraulic test, flaring test, bending, crimping, flattening, apo expansion, apo stretching, microstructure, cup process test, 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 hoʻopaʻa ʻana i ka hoʻomaʻamaʻa ʻana i ka hoʻoheheʻe ʻana i ka haʻihaʻi ʻana, ka nānā ʻana i ka corrosion, etc.

ʻIke a nānā 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 loko o ka metala, alloy.

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.
