Technical QA/QC Verification
• 100% Full-Length Non-Destructive Testing (NDT): SXY Steel Group enforces zero-defect production protocols. Every pipe tube undergo comprehensive ultrasonic (UT), magnetic particle (MPI), and eddy current inspections. The critical friction weld zone is subjected to automated wet MPI flaw detection and 100% real-time computerized weld parameter logging.
• API 5DP Traceability & Premium Hardbanding: Deliveries are backed by authentic EN 10204 3.1 Mill Test Certificates (MTC) specifying exact heat numbers, chemical composition, upsetting geometry, and Charpy V-notch impact toughness values. Tool joints are compatible with Arnco 100XT/300XT or TCS-Titanium hardbanding configurations.
• Capital Security Guarantee: We remove international procurement risks completely by supporting long-term structural drilling tool supply agreements backed via 100% Irrevocable Letters of Credit (L/C) at sight transaction models.
Anti-Rust Packaging & Ocean Logistics
• Thread Protection & Anti-Corrosion Treatment: Machined pin and box threads are fully coated with heavy-duty anti-galling thread storage compound compound and sealed with pressed steel-plastic composite heavy thread protectors to fully block seawater air rust.
• Fortified Steel-Framed Ocean Bundling: To prevent surface scratching and mechanical bending during cross-border transit, drill pipes are secured into heavy protective steel nesting frames or strapped with heavy-duty steel bands utilizing polymer cushioning spacers.
• Extended Port Clearance Support: SXY Steel Group coordinates 14 to 21 days of free container/breakbulk demurrage terms at your specific discharge terminal to provide ample breathing room for your regional customs brokers and overland logistics teams.
Description
Drill pipes are long tubular sections of pipe that make up the majority of the drill string. They are typically a 31 foot long section of tubular pipe but may be anywhere from 18 to 45 feet in length.
Heavy weight drill pipe (HWDP) is a tubular pipe that adds weight or acts as a transitional piece in the drill string. As a transitional section of the drill string, it is placed between the drill collar and standard drill pipe to reduce fatigue failures. In other applications the HWDP is used as an additional weight to weigh down the drill string.
Heavy weight drill pipe is a medium-weight drilling pipe, (referred standards in API SPEC 7-1). It has bigger wall thickness than common drilling pipe and smaller than drill collar.
Drill collars are a component of the drill string that makes up part of the BHA. They are thicker-walled, heavier, and more rigid than drill pipes and are primarily used to weigh down the drill bit while dampening vibration and impact forces.
Drill Pipe:2-3/8″ to 7-5/8″ OD, Range 2 and 3
Heavy Weight pipe:2-3/8″ to 6-5/8″ OD, Range 2 and 3
Drill Collars:2-7/8″ to 14″
Grades: E75, X95, G105, S135
Connection threads:NC26, NC31, NC38, NC40, NC46, NC50, 5 1/2FH.6 5/8FH.
Internal Upset: IU, EU, IEU

Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
