Product Description Product Description Drill pipe is a kind of steel pipe with thread at the tail. It is used to connect the surface equipment of drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of drilling rig.The purpose of the drill pipe is to transport drilling mud to the bit and to raise, lower or rotate the bottom hole device together with the bit. Drill pipe must be able to withstand tremendous internal and external pressure, distortion, bending and vibration.In the process of oil and gas exploitation and refining, drill pipe can be used many times.Drill pipe can be divided into three categories: square drill pipe, drill pipe and heavy drill pipe.The order of connection is square drill pipe (1)+drill pipe (n, determined by well depth)+weighted drill pipe (n, determined by drill tool combination design).The classification of drill pipe, drill pipe joints, drill pipe specifications and steel grade and strength of drill pipe are introduced in detail. Feature1. High-Strength JointFriction welding generates heat through high-speed rotation, creating a metallurgical bond under pressure, achieving 90%-100% of the base material strength-far superior to traditional arc welding (70%-80%).2. No Filler Material RequiredThe process relies solely on plastic deformation of the metal, eliminating the need for welding wire or flux, which reduces contamination risks.3. Narrow Heat-Affected Zone (HAZ)Friction welding's concentrated heat input results in a HAZ width of only 1-3 mm (compared to 5-10 mm in arc welding), minimizing microstructural degradation.4. High Alignment AccuracyAutomated equipment ensures concentricity errors ≤0.2 mm, preventing premature failure due to misalignment-induced stress.5. Energy-Efficient & Eco-FriendlyEach weld takes 20-60 seconds (vs. multi-pass arc welding + heat treatment), reducing energy consumption by >30% with no harmful emissions.6. Compatible with Diverse MaterialsCan join different steel grades (e.g., AISI 4145H pipe body + AISI 4137 tool joint) and even dissimilar metals (e.g., steel-aluminum hybrid joints).

Product ApplicationFriction-welded drill pipes are widely used in demanding drilling operations due to their high strength, durability, and reliable connections. 1. Oil & Gas DrillingOnshore/Offshore Wells: Used in vertical, directional, and horizontal drilling for oil and gas extraction.Deepwater & Ultra-Deep Wells: High-torque resistance makes them ideal for deep (>6,000m) and ultra-deep wells.2. Geothermal DrillingWithstands high-temperature environments (up to 300°C+) in geothermal energy exploration.3. Mining & Mineral ExplorationUsed in core drilling and blast-hole drilling for mineral exploration.4. Water Well DrillingEnsures efficient and long-lasting performance in freshwater and industrial water well projects.5. Horizontal Directional Drilling (HDD)Essential for pipeline and utility installations with smooth torque transmission.6. Scientific & Research DrillingUsed in ice-core drilling (polar research) and geological survey projects.7. Repair & Workover OperationsSuitable for re-entry drilling, sidetracking, and well intervention. There are many product specifications. The price is subject to the actual situation.
