Saver Sub

When rods is added to increase the depth of drilling,the loosening of the threads are now performed at the bottom end of the Saver Sub as opposed to the bottom of the Kelly which is the most valuable part of the drill string.This means that the connection between the top end of the Saver sub and Kelly is seldom used,and suffers minimal wear and tear,whereas the lower connection is used in almost all cases displacing the most wear and tear from the rotary head connection to the much cheaper Saver Sub which is expendable and reduce cost.
Double-Acting Hydraulic Drilling Jar

Double-Acting Hydraulic Drilling Jar has the characteristics of simple operation,adjustable shock tonnage,high temperature resistance,etc.This type of drilling jar adopts a new hydraulic delay release system,which has excellent reliability and wide adaptability.
Fishing Bumper Sub

The Fishing Bumper Sub is Downward Impact Specialist. The Fishing Bumper Sub is Dual-Energy Storage System. The Fishing Bumper Sub is Rugged Mechanical Simplicity. The Fishing Bumper Sub is Adjustable Impact Dynamics. The Fishing Bumper Sub is Multi-Functional Integration.
One-Way Shock Absorber

The one-way shock absorber (bumper )is a kind of drilling tool.It can effect shock absorbing and shock reduction by means of elasticdeforming andanti-coagulationproduced from hydraulic oil under the outside force. Its advantages such as simple structure, reliable workingperformance and easy to maintain can well absorb shocking andvibrating load from drill strings during drilling operation. Therefore, using of shock absorber can raise in structure the service life of drill bit anddrill pipe, speed up drilling, get rid of drilling jumping, well protectsurface equipments and drilling tools.
Double-Acting Hydraulic Mechanical Drilling Jar

Double-Acting Hydraulic Mechanical Drilling Jar provide Dual-Action Efficiency. Double-Acting Hydraulic Mechanical Drilling Jar provide Hydraulic-Mechanical Synergy. Double-Acting Hydraulic Mechanical Drilling Jar, forged alloy steel body with anti-wear coatings ensures longevity in harsh downhole environments.
Casing Scraper

Our Casing Scraper ,each blade is constructed using high quality cast steel for excellent scraping characteristics and long-lasting durability These scraper blades are designed to scrape over 360°of surface area.The scraper blades are designed with a long taper for passing through casing connections with minimal chance of hanging up.
Reduce Sub

Reduced Section Sub is used to connect drill stem parts that have different diameters.This sub can be used to crossover large OD drilling tools or a tapered drill collar string.
Reversing Spear

In driling and workover operation,the reversing spear is a tool mainly used for fishing of drill pipe,oil pipe and casing from fish hole.It can be used with internal cutter,bumper jar,etc.
Reversing Sub

The reversing subs is also called reversing spear which is a special tool for reversing stuck drill stem above stuck point in drilling and workover operation.
Full Opening Safety Valve

Full Opening Safety valve (FOSV) is a ball type safety valve used to stop flowt hrough the drill string when the drill string is being withdrawn from the well.
Drop-in Check Valve

Drop-In Check valves prevent return flow during a kick and are suitablefor most drilling situations in which return flow through the drill string isa risk and normal operation requires the benefits of a full-bore sub. Bypreventing upward flow through the drill pipe and allowing fluid to bepumped downward to circulate the well, the valves provide the driller withthe means to control the drill pipe pressures when required, significantlyimproving and simplifying well control.
Cross-over Sub

Cross over sub is also called Straight OD Sub is used to connect drill stem members that have a similar outside diameter. The drill bit, downhole tools, heavy weight drill pipe and drill pipe can be crossed over using a straight OD sub. Cross over sub are made from AISI 4145H modified quenched and tempered material. In addition, it is designed and manufactured according to API specifications as well as with API monogram. They can be used to crossover from connection size to another or as a disposable component used to extend the connection life of a more expensive drill stem member.
