Product DescriptionProduct Introduction1. Definition and FunctionDrill pipe is a key component in oil and gas drilling operations, mainly used to connect the drilling rig and drill bit, transmit torque and drilling fluid (mud), and support the weight of the drill string. Its core functions include:Power transmission: Transmit the rotational power of the surface drilling rig to the drill bit to achieve formation fragmentation.Drilling fluid channel: The internal hollow structure can transport high-pressure drilling fluid, which is used to cool the drill bit, carry rock debris, and balance formation pressure.Structural support: bear the self weight of the drill string and complex underground loads (such as bending and vibration).2. Structure and MaterialMain structure:It is usually a seamless steel pipe made of high-strength alloy steel, with a single length of about 9-12 meters and an outer diameter range of 60-168 millimeters (common specifications include 73mm, 89mm, 114mm).Key components:Tool Joint: A threaded connection with thickened ends that requires special heat treatment to enhance wear resistance.Pipe Body: Made of API standard steel grades (such as E75, X95, G105), with a tensile strength of 550-1050MPa.3. Classification and StandardsBy purpose: drill pipe (for conventional drilling), weighted drill pipe (for transition section use), drill collar (to provide drilling pressure).International standards: API Spec 5DP (American Petroleum Institute standard), ISO 11961 (International Organization for Standardization).4. Applications and ChallengesApplication areas: onshore/offshore oil and gas wells, geothermal wells, directional drilling, etc.Technical challenge: Need to deal with extreme working conditions such as high temperature and high pressure, corrosive media , fatigue fracture, etc.Other productsIn addition to producing oil drill rods, our tubing&casing couplings, short joints, and pipe reducers have also received good feedback in the market!Transportation and packagingWe offer free product packaging services, including wooden crates, wooden pallets, and customized packaging serviceFAQ1. who are we?We are based in Tianjin, China, start from 1999,sell to North America(16.72%),Mid East(16.67%),South Asia(16.67%),EasternEurope(16.67%),South America(16.67%),Southeast Asia(16.60%).
