ASTM A519 Grade 4130 Oil Well Drilling Pipe , Alloy Round Pipe for Oil Industry
Description
This ASTM A519 Grade 4130 Oil Well Drilling Pipe is a high-performance, seamless alloy steel pipe engineered to meet the rigorous demands of the global oil and gas industry. Manufactured in strict compliance with the ASTM A519 standard, this pipe guarantees exceptional mechanical properties, reliability, and consistency for critical drilling operations in both conventional and challenging environments.
Crafted from AISI 4130 chromium-molybdenum alloy steel, this seamless round pipe offers an outstanding balance of high strength, excellent toughness, and superior fatigue resistance. The seamless manufacturing process ensures a homogeneous structure free from welds, eliminating potential points of failure and providing enhanced structural integrity under extreme cyclical loads, high torsion, and severe compression encountered in deep well and directional drilling applications.
The pipe's chemistry, dominated by chromium and molybdenum, allows it to be heat-treated (quenched and tempered) to achieve precise mechanical properties, making it ideal for applications requiring a robust yet workable material. Its superior yield and tensile strength ensure it can handle the substantial stresses found in drill strings, bottom hole assemblies (BHA), and as heavyweight drill pipe (HWDP), while its good impact resistance helps prevent sudden fractures.
