Product Description Product DescriptionHeavy Weight Drill Pipe(short for HWDP) is an intermediate weight stem component which is used in conjunction with the drill pipe and drill collars. Besdrill HWDP is available in standard, spiral and non-magnetic designs. In some applications, heavy-weight also can be used instead of the drill collars.We Drill Collar has been approved by the NS-1 certification which is made from one-piece 4145H modified quenched and tempered steel. It designed for tough drilling environments in vertical and directional wells; for directional holes it is a weight member and procides additional stiffness to prevent buckling. Feature? A centre upset or wear pad to increase tube life,reduce hole drag and differential sticking problems; ? Connections are completed(phosphate coated) to protect them from the elements after machining and to help prevent galling upon initial make-up; ? Thread roots are cold rolled on and H-90 connections. And pressed steel thread protectors are supplied for standard connections; ? Hardbanding and Internal Coating can be provided on customer's request. Product Parameters Size(in)O.D. (in)I.D.

Our Advantages 1.100+ Factory Options: Access to Chinese/EU/US mills with price benchmarking.2.Smart Sourcing: Recommend optimal specs based on well data (depth/formation/H2S).3.Cost Savings: Bulk purchase discounts & distressed inventory deals (up to 50% off).4.Hassle-Free Logistics: Handle all export docs & sensitive country shipments (Russia/Iran).5.Ironclad QC: Pre-shipment inspection reports + live video verification.6.After-Sales: Drill pipe recycling & market price alerts. Product ApplicationHeavy-duty drill pipes are engineered for extreme conditions like ultra-deep wells, offshore platforms, arctic zones, and sour formations, delivering high strength, corrosion resistance, and fatigue-resistant drilling solutions. 1. Oil & Gas DrillingDeep/Ultra-Deep Wells: Designed for HPHT (High-Pressure High-Temperature) wells exceeding 8,000m (e.g., shale gas, tight oil extraction).Horizontal/Directional Wells: High-torsion resistance (e.g., V150 grade) for extended-reach drilling.Offshore Platforms: Corrosion-resistant alloys (e.g., 4145H) for seawater environments.2. Geological ExplorationScientific Drilling: Continental scientific projects (e.g., China's 7,018m "Songke-2" well).Mineral Prospecting: Paired with diamond bits for core sampling in metal deposits.3. Unconventional EnergyShale Gas/CBM: Fatigue-resistant pipes (e.g., double-shoulder connections) for high-frequency vibrations.Geothermal Wells: Special coatings for 200°C+ operations.4. Harsh EnvironmentsArctic Drilling: -60°C impact toughness (compliant with polar standards).Sour Formations: H2S-resistant (NACE MR0175 certified).5. Engineering & RescueMine Rescue Wells: Reinforced pipes for rd penetration.Landslide Stabilization: Grouting hole construction.
