Product Description
The JIS G3439 standard specifies the requirements for seamless steel tubes used in oil well casing and tubing. This standard is crucial for ensuring the integrity and reliability of pipes used in drilling operations. The various grades under this standard, including STO-G, STO-H, STO-J, STO-N, and STO-C, are designed to meet specific performance criteria in oil drilling applications.
The seamless steel tubes covered by JIS G3439 are manufactured from high-quality carbon and alloy steels. These materials are selected for their strength, durability, and resistance to corrosion, which are essential for the harsh conditions encountered in oil drilling.
The specifications for JIS G3439 seamless steel tubes include dimensions, tolerances, and mechanical properties that ensure the tubes can withstand high pressures and temperatures during drilling operations.

The steel grades specified in JIS G3439 are categorized based on their chemical composition and mechanical properties. Each grade is tailored for specific applications and performance requirements in oil drilling.
The seamless steel tubes produced under JIS G3439 are primarily used in:
While JIS G3439 grades are widely used, alternative grades may be considered based on specific project requirements. Some possible alternatives include:
These alternatives may offer similar mechanical properties and chemical compositions, making them suitable for various oil drilling applications.
A: manufacturer,also can do trading.
A: Generally speaking,it is 10-15 days if the goods are in stock,or it is 30-40 days if the goods are not in stock, it is according to quantity.
