Product Description

 Introduction

Casing is used for strut in gas or oil well to ensure that regular work. Number of casings used is up to drilling depth and geology condition. After casing sunk into the well, well cemented. Casing is disposable consumable, which is different from tubing and drill pipe, and occupies over 70% of total consumable pipes.Oil casing steel grade: H40 J55, K55, N80, L80, C90, T95, P110, Q125, etc.

Set of tube end processing form: flat end, short round thread, long thread, buttress thread, special buckle

The main purpose

Used in oil well drilling is mainly used in the drilling process and after the completion of borehole wall support, to ensure that the drilling process and after completion of the normal operation of the oil Wells.
