Ihe Ịma Aka na Ngwọta Teknụzụ:

● Mgbanwe dị oke elu na okpomọkụ– Elu paịpụ dị site na 400m ruo 2,800m, yana okpomọkụ gburugburu site na -35°C n'oge oyi ruo +45°C n'oge ọkọchị. Paịpụ 48" X70 chọrọ ike okpomọkụ dị ala ruo -46°C (Charpy min 50J). Womic họọrọ efere TMCP nwere mgbakwunye nickel (Ni ≤ 0.50%) iji nweta mmetụta Charpy na -46°C nkezi 120J. DWTT na -20°C ebe a na-akpụ ihe: 92-96% maka ahụ paịpụ, 82-88% maka ịgbado ọkụ. Nnwale niile gafere.

● Ịgafe ebe mgbawa mmiri - imewe dabere na nrụgide– Akụkụ paịpụ anọ na-agafe nsogbu ndị na-arụ ọrụ nke nwere ike ịkwaga ala ruo mita 1.5. E ji nhazi dabere na nrụgide mee paịpụ ahụ. Nke a chọrọ paịpụ X70 nwere oke mkpụrụ ≤ 0.85 (API 5L PSL2 na-enye ohere 0.93) na ogologo otu ≥ 15%. Womic mepụtara X70 pụrụ iche "oke nrụgide" nke nwere oke mkpụrụ 0.80-0.84 na ogologo otu 16-18%. Anyị nyekwara nnwale nrụgide zuru oke (ọ bụghị naanị eriri) iji chọpụta ikike nrụgide.

● Ala ugwu nwere mkpa ịgbagọ agbagọ nke ukwuu– Paịpụ ahụ gụnyere 22 km nke paịpụ 48" arụnyere na mkpọda nke ogo 20-30. Ngbagọ oyi nke paịpụ X70 dị oke (API 5L na-enye 1.5° kwa 12m). Womic nyere paịpụ nwere njikọ 18m ogologo karịa maka akụkụ kwụ ọtọ na njikọ 12m maka akụkụ gbagọrọ agbagọ. Anyị mekwara nnwale gbagọrọ agbagọ na ihe nlele zuru oke: a gbagọrọ paịpụ 48" × 19.0mm oyi ruo 2.0° kwa 12m na-agbawaghị agbawa (UT na MT kwadoro ya mgbe agbagọchara).

● Ịgafe osimiri nke chọrọ ọkpụrụkpụ mgbidi dị arọ– Ebe atọ e si agafe osimiri (Oxus tributaries) chọrọ 22.2mm WT kama 19.0mm maka mmebi na iguzogide mgbagọ ọzọ n'oge nrụnye azụ. Womic jiri usoro UOE maka paịpụ ndị a iji nweta ovality ≤ 0.2% (n'ezie 0.12-0.18%), na-ahụ na ọ na-aga nke ọma site na oghere ahụ. Paịpụ mgbidi ndị ahụ siri ike chọkwara obere ntinye okpomọkụ n'oge ịgbado ọkụ (≤ 2.0 kJ/mm) iji nọgide na-enwe ike HAZ.

● Njem njem dị anya n'ofe mba atọ– E mepụtara paịpụ ndị a n'ụlọ ọrụ Tianjin nke Womic, e jiri ụgbọ okporo ígwè ziga ha na Almaty (Kazakhstan), wee bufee ha na gwongworo maka ibuga ha na mgbasa ihe owuwu na Uzbekistan na Tajikistan. Ogologo njem niile: ihe karịrị kilomita 5,000. Womic jiri ụgbọ okporo ígwè pụrụ iche nwere ihe nkwado a kpụchara akpụcha na ihe mkpuchi ígwè.

● Ihe mkpuchi dị oke mkpa maka ikpughe UV dị elu– N'elu elu mita 2,800, radieshon UV dị elu karịa 40% karịa n'ọkwa oké osimiri. Standard 3LPE nwere ike imebi na UV dị elu. Womic tinyere 3LPE na akwa elu UV emelitere (ọdịnaya ojii carbon 2.5% vs ọkọlọtọ 2.0%). Mkpuchi ahụ gafere ule ihu igwe UV ngwa ngwa (awa 1,000 QUV, njigide gloss ≥ 80%). Ike akpụkpọ ahụ nọgidere > 200 N/cm mgbe ekpughere UV.

● Nsonaazụ:Emechara ma nye ọrụ ịgbatị paịpụ 140 km na nkeji nke abụọ nke afọ 2025. Paịpụ X70 PSL2 niile dị tọn 75,800 gafere nyocha TÜV na-enweghị ihe ọ bụla a jụrụ.
