ʻO ka API 5L kahi kikoʻī i hoʻomohala ʻia e ka American Petroleum Institute (API) e uhi ana i nā paipu laina kila humuhumu ʻole a me nā paipu i hoʻopaʻa ʻia. Hoʻohana nui ʻia kēia mau paipu no ka lawe ʻana i ka ʻaila a me ke kinoea i loko o ka ʻoihana paipu.
Nā kikoʻī a me nā papa
Nā Papa: Loaʻa nā paipu API 5L i nā papa like ʻole e like me ka Papa A, B, X42, X52, X60, X65, X70, a me X80, e hōʻike ana i nā pae ikaika like ʻole.
Nā ʻAno: Hoʻokomo pū ʻia ʻo PSL1 (Pae Kikoʻī Huahana 1) a me PSL2 (Pae Kikoʻī Huahana 2), me PSL2 i loaʻa nā koi koʻikoʻi no ka haku mele kemika, nā waiwai mechanical, a me ka hoʻāʻo ʻana.

Ka Mana Kūlana Koʻikoʻi:
1) I ka wā a ma hope o ka hana ʻana, 4 mau limahana QC me ka ʻoi aku o 5 mau makahiki o ka ʻike e nānā i nā huahana ma kahi random.
2) Keʻena hoʻokolohua i hōʻoia ʻia e ka ʻāina me nā palapala hōʻoia CNAS
3) Nānā ʻae ʻia mai ka ʻaoʻao ʻekolu i koho ʻia/uku ʻia e ka mea kūʻai, e like me SGS, BV.
4) Ua ʻāpono ʻia e Malekia, ʻInidonesia, Singapore, Pilipine, ʻAukekulelia, Peru a me UK. Loaʻa iā mākou nā palapala hōʻoia UL /FM, ISO9001/18001, FPC
