NSEN yakagadzirira mavharuvhu maviri, anosanganisira mavharuvhu e150LB ne600LB, uye ese ari maviri akapasa bvunzo yemoto.

Saka, chitupa cheAPI607 chakawanikwa parizvino chinogona kufukidza zvizere chigadzirwa, kubva pakumanikidzwa kwe150LB kusvika 900LB uye saizi ye4″ kusvika 8″ uye yakakura.

Kune mhando mbiri dzechitupa chekuchengetedza moto: API6FA neAPI607. Chekutanga chinoshandiswa kumavharuvhu akajairwa eAPI 6A, uye chechipiri chinoshandiswa zvakananga kumavharuvhu anoshanda emadhigirii makumi mapfumbamwe akadai semavharuvhu emabhuruvhu nemavharuvhu ebhora.

Zvichienderana nechiyero cheAPI607, vharuvhu yakaedzwa inofanira kupiswa mumoto we750℃ ~ 1000℃ kwemaminitsi makumi matatu, uye yobva yaita bvunzo dze1.5MPA ne0.2MPA kana vharuvhu yatonhodzwa.

Mushure mekupedza bvunzo dziri pamusoro apa, imwe bvunzo yekushanda inodiwa.

Valvu inogona kupasa bvunzo chete kana kuyerera kwemvura kwakayerwa kuri mukati mechiyero chakajairwa chebvunzo dzese dziri pamusoro apa.
