Tubing head is a spool with flange top, flanged bottom and two side outlets. It also can be called tubing spool. Top flange is equipped with lock screws to fix tubing hanger. Tubing head is installed on top of casing head, which consists of body housing and tubing hanger. It can hang tubing string and seal the annular space between tubing and production casing. Our company can manufacturer tubing head with standard structure, which includes tubing hanger installed on the cone of body housing. Tubing hanger can be tapped with BPV thread as per request.

API 6A Check Valve, also referred to non-return valve, or one-way valve, is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. We can produce both swing type check valve and lift type check valve. Available in bore sizes from 1-13/16" to 7-1/16" and pressure ratings from 2,000 to 15,000 PSI. The standard material is forged AISI4130 alloy. All of our Check Valves are fully designed, manufactured, and tested as per API 6A and API 16C standards and have been widely used on oilfield wellhead Christmas tree and manifolds with reliable performance. 

Accumulator unit for BOP stacks is a very important equipment which controls BOP stacks and gate valves controlled by hydraulic pressure especially in drilling and workover operations. It is necessary to accurately operate and maintain the hydraulic control system. It consists of remote control system, driller’s panel, air cable (except electrical type), pipe rack (electrical warming system available for cold area), high pressure manifold, protection room, etc. 

Tricone drill bits: A tricone bit comprises three conical rollers with teeth made of a hard material, such as tungsten carbide. The teeth break rock by crushing as the rollers move around the bottom of the borehole.

PDC drill bits: A PDC bit has no moving parts and works by scraping the rock surface with disk-shaped teeth made of a slug of synthetic diamond attached to a tungsten carbide cylinder

PDC drag bit: A drag bit is a comprehensive drilling bit, mainly used for water wells, mining, geothermal, environmental and exploration drilling. It is suitable for drilling in soft and soft-medium formations with fast penetration rate and high efficiency, and special for the large diameter holes’ drilling.
