1. 'Oloka'a 'ia nā paipu kila ma'amau mai ke kila kila ma'amau, ke kila kila ha'aha'a a i 'ole ke kila kila e like me ka mea. No ka laʻana, hoʻohana nui ʻia nā paipu seamless i hana ʻia me ke kila kalapona haʻahaʻa e like me ka No. 10 a me No. ke kila kalapona waena e like me 45 a me 40Cr Hoʻohana nui ʻia nā paipu seamless i hana ʻia e hana i nā ʻāpana mīkini like ʻole a me nā paipu paipu.

2. Hoʻolako pū ʻia nā paipu kila maʻemaʻe no nā kumu maʻamau e like me ka haku mele a me nā waiwai mechanical, a e like me ka hoʻāʻo hydraulic. ʻO nā paipu kila maʻemaʻe ʻole e kau ana i ke kaomi wai e pono e hele i ka hoʻāʻo ʻana i ka hoʻoemi hydraulic.

3. Hoʻohana ʻia nā paipu wili ʻole kūikawā i nā boilers, ka ʻimi geological, nā bearings, acid resistance, etc. E like me ka petroleum geological drilling pipeAPI 5CTJ55, K55, N80, L80, P110, Etc, nā paipu pohā a me nā paipu paila no ka ʻoihana petrochemical.

Nā paipu kila maʻemaʻehoʻohana nui ʻia no nā hale maʻamau a me nā hale mechanical. ʻO kāna mau mea i hōʻike ʻia (nā māka): ke kila kalapona No. 20, No. 45 kila; kila kila Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.

Hoʻohana nui ʻia nā paipu kila ʻole no ka lawe ʻana i nā wai no ka lawe ʻana i nā pipeline wai i ka ʻenekinia a me nā mea hana nui. He 20, Q345, etc.

ʻO nā paipu kila liʻiliʻi no ke kaomi haʻahaʻa a me ka haʻahaʻanā pailaHoʻohana nui ʻia no nā pipeline e lawe ana i nā wai haʻahaʻa haʻahaʻa a me ka liʻiliʻi i nā boilers ʻoihana a me nā boilers home. ʻO nā mea i hōʻike ʻia he 10 a me 20 kila.

ʻO nā paipu kila ʻole nokiʻekiʻe-press boilershoʻohana nui ʻia no nā poʻomanaʻo a me nā paipu i loko o nā mea kanu mana a me nā mea kanu nuklea. ʻO 20G, 12Cr1MoVG, 15CrMoG, etc.

ʻO nā paipu kila ʻole nomea hoʻomomona kiʻekiʻeHoʻohana nui ʻia nā mea hana no ka lawe ʻana i nā pipeline wai wela kiʻekiʻe a kiʻekiʻe ma luna o nā mea momona. He 20,16Mn,12CrMo, 12Cr2Mo, etc.

Hoʻohana nui ʻia nā paipu kila maʻemaʻe no ka haki ʻana i ka ʻaila i loko o nā paila, nā mea hoʻololi wela a me nā pipeline lawe wai i nā mea kanu hoʻoheheʻe ʻaila. ʻO kāna mau mea kikoʻī he 15mog, 15CrMoG, 12crmog, etc.

Hoʻohana nui ʻia nā paipu kila maʻemaʻe ʻole no ka hana ʻana i nā pahu kinoea a hydraulic like ʻole. ʻO kāna mau mea kikoʻī he 37Mn, 34Mn2V, 35CrMo, etc.

Hoʻohana ʻia nā paipu kila maʻemaʻe wela no nā props hydraulic, kahi i hoʻohana nui ʻia e hana i nā kākoʻo hydraulic, nā cylinders a me nā kolamu i loko o nā mines lanahu, a me nā pahu hydraulic ʻē aʻe a me nā kolamu. ʻO kāna mau mea kikoʻī he 20, 45, 27SiMn, etc.

Hoʻohana nui ʻia nā paipu kila liʻiliʻi i huki ʻia i ke anu a i ʻole nā ​​mea hoʻoheheʻe kalapona, e koi ana i ka pololei kiʻekiʻe a me ka hoʻopau maikaʻi. ʻO kāna mau mea i hōʻike ʻia he 20, 45 kila, etc.

Hoʻohana nui ʻia nā paipu kila maʻemaʻe a me nā paipu kila kūikawā no ka hana ʻana i nā ʻāpana a me nā ʻāpana like ʻole. Hana ʻia lākou me ke kila kila kila kiʻekiʻe a me ke kila kila haʻahaʻa.

Hoʻohana nui ʻia nā paipu kila i loko o ke anawaena no ka hydraulic a me ka pneumatic cylinders no ka hana ʻana i nā paipu kila liʻiliʻi a i ʻole i ʻōwili ʻia i ke anu me nā anawaena pololei o loko no nā cylinders hydraulic a pneumatic. ʻO kāna mau mea kikoʻī he 20, 45 kila, etc.
