Subs And Lifting Tools

Lifting Cap (PLUG)

Lifting caps are tools for lifting of drilling tools, such as drill collars or stabilizers. 1. Thread Protection & Lifting Integration - Forged alloy steel body shields API connections from impact, debris, and corrosion. - Integrated lifting shoulder or bore enables direct connection to lifting tools, replacing traditional slings/cables. 2. High-Load Safety Engineering - Rated for loads exceeding 50 tons with 3:1 safety factor; proof-tested per API . - Fail-safe lock pins/retention clips prevent accidental disengagement during lifting.
Buckle Joint

1.Buckle Joint has Buckling Resistance Superiority - Fortified design counters compressive/torsional stresses that induce helical or sinusoidal buckling, protecting strings in extended-reach drilling (ERD) and deepwater wells. - Integrates seamlessly between drilling tools (e.g., drill collars, HWDP) or casing segments to localize strain. 2.Buckle Joint has High-Strength Material Science - Forged from AISI 4145H modified alloy steel, heat-treated for unmatched yield strength (≥ 120 ksi) and fracture toughness. - Internal/external coatings combat erosion, corrosion, and galling.
TEE

1. oil tools Tee(three-way connection)Robust Three-Way Flow Control: Provides a durable, high-integrity three-way connection (equal or reducing) for directional flow changes (90° branch) in critical oilfield piping networks (e.g., mud circulation, cementing, fracturing, production flowlines). 2. oil tools Tee(three-way connection) High-Pressure & Temperature Rating: Manufactured from premium forged alloy steel (e.g., AISI 4130/4140, F22, F91) or stainless steel, heat-treated for exceptional yield strength. Rated for working pressures exceeding 5,000 psi (34.5 MPa) and high temperatures encountered in drilling and production.
Drill Pipe Sub

1. Drill Pipe Sub has Premium Connection Integrity: Features precisely machined API-registered (e.g., NC, FH, IF) or proprietary thread connections on both ends, guaranteeing seamless compatibility with standard drill pipe and downhole drilling tools. Ensures leak-proof performance for drilling fluid circulation. 2. Drill Pipe Sub has Exceptional Strength & Durability:Manufactured from high-grade alloy steel (e.g., AISI 4145H modified) and subjected to rigorous heat treatment processes (quenching & tempering) for superior yield strength, toughness, and resistance to fatigue, shock loads, and abrasive wear common in drilling environments.
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.
Circulating Sub

The Circulating Sub is connected between wellhead pipe string and ground circulating system.When casing is running or completed,the circulating sub can be connected to provide fluid circulation. According to the application,circulating sub is connected between Kelly and casing or between casing and a hose.
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.
Lift Sub

A lift Sub enables safe and efficient handling of straight OD tubulars such as drill collars,shock tools,jars,directional equipment and other tools by using the drill pipe elevators.
Float Valve Sub

Float valve Sub is an important tool in petroleum exploration and drilling engineering.The float valve sub is connected at upper part of drill bit.The float valve sub is near the bit connecting thread.The float valve sub can also be used at different necessary position of drill string when required.The main application is,when connected with single piece pipe,it prevents mud from coming in and up blocking the hole.When blowout takes place,blowout in drill string will be avoided because nozzle is closed automatically by valve cap of the float valveassembly.
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.
Wear Sub

XINRUIDE wear sub consists of a highly wear rubber sleeve,a metal stiffening liner and a sub body.The rubber sleeve is installed in the middle of sub body and some clearance is given to allow sleeve to rotate freely.The rubber sleeves are made of rubber mixtures with good wear resistance.
Oriented Bent Sub

The oriented bent sub is a major power deflection tool having a fixed angle deviated from the low end thread of the bent sub to the axial line of drill stem.Under the application of oriented bent sub the power drill tool give the bit a constant lateral force to ensure that the bit can cut on the well wall laterally and further drill into a curved well trace.
