Imiyoboro ya DTH yose ya DTH ni friction irasudwa, kandi mubisanzwe insanganyamatsiko ni ihuza rya API risanzwe, nka 2 3/8 ″ Urudodo rwa API REG, 3/2 ″ Urudodo rwa API REG cyangwa API NIBA urudodo, nibindi Ukurikije abakiriya babisabye, kuva 1000mm kugeza 5000mm z'uburebure, OD dushobora gutanga 50mm, 60mm, 76mm, 89mm, 102mm

Amababa y'ibicuruzwa:

1.
2: Gukoresha R780 nkibikoresho byumubiri winkoni kugirango utezimbere kwambara nimbaraga, 42 Cr Mo ibikoresho byo guhuza umugozi.
3: Yemera ubuvuzi bubabaza kugirango agabanye uburemere bwinkoni mugihe agumana imbaraga za weld (ubunini bwaumuyoboroni 6.5mm mugihe aho gusudira ari 8.5mm).
