1.Polish rod mangrupakeun jenis rod mamat husus disambungkeun jeung rod mamat jeung gantungan beam. Éta aya di luhureun rod mamat, kedah nanggung kakuatan anu paling kuat, janten kalayan diaméter anu langkung ageung sareng kelas baja anu langkung luhur tibatan rod mamat, sareng permukaanna mulus pisan.
2. Fungsi utama:
Digabungkeun sareng packing set dina kotak packing pikeun ngégél wellhead jeung nyegah minyak, gas, panyingkepan cai.
Panyambung interim antara rod mamat jeung gantungan sirah bigal
Tes diagram indikator rengse.
Ngalengkepan rupa operasi wellhead, kayaning pompa ngahalangan, ngatur setelan pompa.
