Well Drilling Pipe
Fandrefesana fantsona dia be mpampiasa amin'ny fitrandrahana harena an-kibon'ny tany, fikarohana ara-jeolojika sy ny karazana fandavahana (rano, solika, entona, sns) tetikasa. Amin'ny maha-mpitarika faladiany sodina fanamboarana, dia manao isan-karazany ny fenitra sy tsy manara-penitra fantsona fantsona ho an'ny mpanjifa.Ny fantson-drivotra misy anay ao anatin'izany ny sodina vy, ny fitrandrahana harena ankibon'ny tany, ny fantson-drano, ny fantson-tsolika, ny sodina API, ny DTH drill rod, ny wireline drill rod, sns.
Ny singa fototra amin'ny fantsona DTH avo lenta dia ny faharetana, ny fahitsiana ary ny fitantanana.
1. Sodina vatana: mangatsiaka misintona seamless sodina.ka ny sodina dia manana ny habeny marina, centralizer tsara.
2.Mitovy naoty amin'ny Sandvik ny fitaovan'ny vatana fantsona.
3.Thread connector: Heat sy Nitrogen fitsaboana, noho izany ny sodina dia mateza kokoa sy mora kokoa ny entana sy ny famoahana entana.
4.Friction welding .
