Ka whakarei ake te kume makariri i te mana whakahaere me te mutunga o te mata o te ngongo, kia pai ai mō ngā tono ahumahi tino tika.

Ko te tukanga whakaputa o ngā ngongo maitai tino tika ko ngā wāhanga e whai ake nei:

Te tirotiro i ngā rauemi mata
Te whakarite i te ngongo whaea kua hurihia wera
Te tukatuka tuhi matao
Te maimoatanga wera me te whakamamae i te ahotea
Te whakatikatika me te tapahi
Te tirotiro i ngā āhuatanga me te whakamātautau kounga

Me āta whakahaere i ia wāhanga o te whakaputanga kia tutuki ai ngā ngongo whakamutunga i ngā whakaritenga tino pakari kua tautuhia e ngā paerewa o te ao.

Ko tētahi o ngā paerewa e whakamahia whānuitia ana mō ngā ngongo tika i Ūropi koEN10305, e tohu ana i ngā ngongo maitai tino tika kua kumea matao mō ngā mahi miihini me te waipēhi. Kei roto i te EN10305 ētahi wāhanga e kapi ana i ngā tikanga hanga me ngā tikanga tuku rerekē.

Ko ngā māka e whakamahia whānuitia ana i raro i tēnei paerewa koE355 me E235, he rauemi maitai waro he kaha rawa atu, he ngāwari hoki ki te miihini.

Kei te ripanga e whai ake nei te whakarāpopototanga o ngā mea noaEN10305 ngā tohu ngongo tika.

Paerewa	Tau	Te Whakamahinga Noa
EN10305	E235	Hangarau mīhini
EN10305	E275	Ngā wāhanga hangarau hanganga
EN10305	E355	Ngā rango waipēhi me ngā mīhini

I roto i ēnei rauemi,Ngā ngongo tika E355He tino rongonui ēnei i roto i ngā ahumahi hangarau waipēhi me te miihini nā te mea he kaha teitei, he tino tika hoki ngā āhuatanga.

He pai te mahi miihini me te mahi pono o ngā ngongo E355 i roto i te hanga rango waipēhi me te hanga mīhini tino tika.

Ko tētahi atu whakatakotoranga e whakamahia whānuitia ana mō ngā ngongo tika tui koDIN2391, he paerewa ahumahi Tiamana e tautuhi ana i ngā ngongo maitai tui kore e kumea mataotia ana mō te miihini me ngā pūnaha waipēhi.

E mōhiotia ana ngā ngongo DIN2391 mō ō rātou āheinga ā-rahi me ngā āhuatanga miihini ōrite. Ko te rauemi e whakamahia whānuitia ana i raro i tēnei paerewa koST52, e tuku ana i te kaha teitei me te ngāwari ki te whakarewa.

E whakaatu ana te ripanga e whai ake nei i ngā āhuatanga noaNgā kōeke ngongo tika DIN2391.

Paerewa	Tau	Tono
DIN2391	ST52	Ngā rango waipēhi
DIN2391	ST45	Ngā taputapu mīhini
DIN2391	ST37	Hangarau whānui

E whakamahia pinepine ana ngā ngongo tika tui DIN2391 ST52 i roto i ngā oko rango waipēhi, i ngā anga taputapu mīhini, me ngā wāhanga mīhini ahumahi e hiahiatia ana te kaha teitei me te tika o ngā āhuatanga.

Haunga ngā paerewa o Ūropi, e whakamahia whānuitia ana hoki ngā paerewa ASTM o Amerika i roto i ngā tono ngongo tino tika.

Ko ngā paerewa ASTM e tautuhi ana i te hanganga matū me ngā āhuatanga hangarau o ngā ngongo maitai e whakamahia ana i roto i ngā pūnaha pēhanga, ngā whakawhiti wera, me ngā taputapu miihini.

He maha ngā whakaritenga ASTM e whakamahia whānuitia ana mō ngā tono ngongo maitai tino tika.

Paerewa ASTM	Taumata Noa	Tono
ASTM A106	Taumata B	Ngā pūnaha miihini me te pēhanga
ASTM A179	A179	Ngā ngongo whakawhiti wera
ASTM A213	T11 / T22	Ngā ngongo koranu pāmahana teitei

E whakamahia whānuitia ana ngā ngongo tui ASTM A106 Grade B i roto i ngā pūnaha paipa ahumahi me ētahi tono miihini e hiahia ana ki ngā ngongo maitai tui kaha.

Ko ngā ngongo ASTM A179 e whakamahia ana i roto i ngā whakawhiti wera me ngā whakapūmau wera ina hiahiatia he mahi whakawhiti wera whai hua.

Nā te mea he rerekē ngā whakaritenga hangarau a ngā ahumahi rerekē, me āhei ngā kaihanga ki te whakaputa ngongo tika kia rite ki ngā paerewa o te ao maha.

Ka hangaia e Womic Steel ngā ngongo maitai tino tika e ai ki ngā paerewa matua o te ao., tae atu kiEN10305, DIN2391, ASTM A106, me ASTM A179, me te whakarite kia hototahi ki ngā whakaritenga hangarau o te ao.

Ko tētahi o ngā painga matua o ngā ngongo maitai tino tika ko tōna ātete ki ngā āhuatanga. He maha ngā wā ka hiahiatia he ngongo me te whānui o waho me te matotoru o te pakitara kia tino tika mō ngā rango waipēhi me ngā wāhanga mīhini tino tika.

E whakaatu ana te ripanga e whai ake nei i ngā āhuatanga noangā rerekētanga manawanui i waenga i ngā ngongo paerewa me ngā ngongo tino tika.

Momo Ngongo	Manawanui Ahu
Ngongo Tuitui Paerewa	±1% OD
