Product Description Coupling(Drill Pipe Coupling / Tubing Coupling / Oilfield Coupling)Product DescriptionA Coupling is a cylindrical connecting component used to join two sections of drill pipe, tubing, or casing in oilfield operations. It ensures the mechanical integrity of the drill string while maintaining pressure containment in the wellbore.Couplings transmit torque, axial loads, and bending forces between connected pipe segments, allowing safe and efficient drilling, completion, and workover operations. Product ParametersSpec / FeatureTypical / Available OptionsStandard / ComplianceManufactured per API Spec 5B / ISO 11960 / ISO 13679, covering drill pipe and tubing couplings. Pressure RatingsSuitable for high-pressure operations up to 10,000 psi or more depending on coupling size and material.Thread Type / ConnectionAPI regular, premium (e.g., NC, LTC, IF, BTC); internal or external threads depending on pipe type. MaterialsHigh-strength alloy steels (e.g., AISI 4145H, 4130) with optional heat treatment; corrosion-resistant coatings or NACE MR-0175 compliance for sour environments.Size Range / CompatibilityCompatible with drill pipe/tubing diameters from 2-3/8″ to 6-5/8″, or as specified per operation requirements.Design Features- Full strength design for torque and tensile loads - Anti-rotational and precision-machined threads - Optional hardened internal surfaces to reduce wear - Interchangeable with major OEM brands Product AdvantagesHigh Mechanical Strength: Ensures drill string integrity under high axial loads, bending, and torsional stress.Reliable Sealing & Pressure Containment: Threads and precision machining maintain wellbore pressure integrity.Interchangeable & Versatile: Compatible with a wide range of drill pipes, tubing, and casing; reduces spare part inventory.Durable Construction: Alloy steel with heat treatment and optional corrosion-resistant coating provides long service life even in sour or high-pressure environments.Standards-Assured Safety: Compliance with API and ISO standards guarantees reliable performance and operational safety. Company StrengthsExtensive experience in manufacturing and exporting oilfield couplings and related drill string components.Advanced machining, threading, and heat treatment facilities to ensure high precision and durability.Quality Assurance: all couplings undergo dimensional checks, thread inspection, hardness tests, and pressure testing.Comprehensive after-sales support: spare parts, replacement couplings, and technical guidance available.ActionContact us today to request a quote for our high-quality oilfield Couplings - specify pipe diameter, thread type, material, and pressure rating.
