Drill Collar-Slick lan Spiral Downhole Pipe
Kolar pengeboran digawe saka AISI 4145H utawa rampung rolling baja paduan struktural, diproses miturut standar API SPEC 7.
Ing kabeh proses produksi krah pengeboran, data tes tes kinerja saben item, saka workblank, perawatan panas kanggo nyambungake benang lan proses manufaktur liyane, bisa dilacak.
Deteksi krah pengeboran rampung kaya standar API.
Kabeh benang ngalami perawatan fosfatisasi utawa plating tembaga supaya bisa nambah resistensi karat lan ngindhari fenomena gluing benang alat.
Perusahaan kita bisa ngolah slip lan alur lift ing krah pengeboran miturut syarat pangguna.
