Custom Heavy Weight Drill Pipe Manufacturer in China
Heavy Weight Drill Pipe (HWDP) is an intermediate-weight component used in the drill string. It helps transition stiffness and weight between the heavier drill collars and the lighter drill pipe, reducing fatigue failures. We offer HWDP for various drilling applications, ensuring high strength and reliability in challenging downhole conditions.

We commit to superior materials, precision engineering, and quality control, ensuring high-strength, durable, and reliable drilling components for challenging oilfield applications worldwide.
Heavy Weight Drill Pipe Benefits
Reduces Drill String Fatigue HWDP acts as a transitional element between stiff drill collars and more flexible drill pipe. This smooth transition effectively dampens bending stresses, significantly preventing fatigue failures in the drill string.
Aids in Directional Control Its increased stiffness and weight help maintain stability and bottom-hole assembly integrity. This is particularly valuable in directional and horizontal wells, allowing for better toolface control.
Provides Necessary Weight-on-Bit (WOB) Being heavier than standard drill pipe, HWDP can contribute substantially to the total WOB required for efficient drilling. It reduces the need for as many heavier, less flexible drill collars.
Minimizes Differential Sticking Risk The central upset or wear pad on standard HWDP minimizes the contact area with the wellbore wall. This design feature reduces the potential for differential sticking in permeable formations.
Heavy Weight Drill Pipe Applications
Transition Section in the Drill String: HWDP is strategically placed between the stiff, heavy drill collars and the more flexible drill pipe. This placement creates a smooth, gradual transition in stiffness and weight, which is essential to significantly minimize stress concentrations and reduce the risk of fatigue-related failures in the string during drilling operations.
Weight-on-Bit (WOB) Provision: The increased mass of the HWDP provides crucial additional weight directly above the bottom hole assembly (BHA) and the drill bit. This extra weight helps maintain the necessary force, known as WOB, which is required to efficiently penetrate the formation, particularly in vertical or shallow wells.
Directional and Horizontal Drilling: In complex, non-vertical drilling, HWDP is used for its superior stiffness, which aids in maintaining a stable wellbore and controlling the trajectory. It is particularly effective for controlling the angle and direction of the well path to precisely hit target zones.
Reduced Differential Sticking: The thicker body and increased clearance of spiral or integral HWDP designs, often featuring a center upset, minimize the contact area with the wellbore wall. This design feature is vital for reducing the risk of differential sticking when drilling through permeable formations under high-pressure conditions.
Various Heavy Weight Drill Pipe
custom heavy weight drill pipes
We offer fully customized Heavy Weight Drill Pipes (HWDP) to meet your specific drilling demands. Options include various configurations (integral or welded), proprietary and double-shoulder connections, internal plastic coating, and application-specific hardbanding. Tailor the size, steel grade (e.g., API, Sour Service, high-strength), and spiraling to optimize performance and fatigue resistance in your challenging downhole conditions.
integral heavy weight drill pipe
We offer integral heavy-weight drill pipe (HWDP), forged from a single piece of AISI 4145H alloy steel. This monoblock construction eliminates welds, providing superior strength and fatigue resistance in the transition zone between drill collars and drill pipe. Our integral hwdp is fully heat-treated to API spec 7 standards.
API 5DP heavy weight drill pipe (hwdp)
We offer API 5DP heavy weight drill pipe (HWDP) to meet stringent industry standards. our hwdp, available in grades like x95, g105, and s135, serves as a crucial transition in the drill string, mitigating fatigue and enhancing directional drilling control. we provide multiple upset and connection styles, ensuring reliability for your most demanding downhole operations.

We offer top-quality heavy weight drill pipe (HWDP), designed as the critical transition between rigid drill collars and flexible drill pipe. Our standard and spiral HWDP is manufactured from premium alloy steel, featuring hardbanding and fatigue-resistant connections. We also provide striking bar speed rods for top hammer rock drilling, ensuring efficient impact energy transfer and superior penetration rates in hard formations.
Customize Your Desired Heavy Weight Drill Pipe
Hardbanding Selection and Placement
We offer various hardbanding alloys like tungsten carbide or proprietary wear-resistant materials for tool joints and center wear pads. You can customize the application pattern, such as full-coverage or recessed bands, and material grade to significantly increase pipe lifespan, reduce wear on the casing and tool joint, and minimize friction in abrasive formations
Connection Type and Torque Capacity
We customize the rotary-shouldered connection (RSC) to match your rig’s capabilities and downhole torque requirements. We offer common API connections (e.g., NC50) or specialized high-torque connections for deep or extended-reach drilling. Customizing the thread compound and connection shoulder design ensures maximum joint strength and sealing integrity, preventing backing-off.
Body Design (Standard vs. Spiral)
We offer the choice between standard body HWDP and spiral-grooved body HWDP. The standard body provides simplicity and maximum weight, while the spiral design features external grooves. We customize the spiral pitch and depth to reduce contact area, which is vital for minimizing differential sticking risk in permeable formations and improving mud circulation in deviated wells.
Material Grade and Wall Thickness
We select the optimal steel material grade (e.g., API grades X95, G105, S135) based on the required yield strength, and the wall thickness is adjusted. Customizing these aspects ensures the pipe can handle the necessary torque and tension loads while maintaining the correct flexibility and weight. This prevents pipe body failure in high-stress directional drilling applications.
