Iljin Steel products

OCTG is steel piping used for oil and natural gas extraction and drilling. Casing is usually installed on rigs to prevent the breakdown of the oil well and the wall. It can also prevent foreign matter from entering the extraction process e.g., water or soil. Tubing transports the oil and gas from well to the on ground floor. ILJIN Steel has produced and supplied high-value products for industry sectors in extreme temperatures and pressures, building our industry reputation as a seamless pipe manufacturer.

OCTG refers to steel pipes used in the extraction of natural gas, oil and rig drilling. The drill pipe delivers a rotational movement of the ground drills attached to the bottom end of the excavation equipment and injects water for cooling. ILJIN Steel has supplied high quality Drill Pipes of a wide range of specifications to meet customer’s requirements including API. We are recognized for the high reliability and quality of our products in oil- and gas-drilling sites worldwide.

ILJIN Steel manufactures a wide range of line pipes for onshore and offshore applications. Line pipe is available in sizes ranging from NPS 1" to 6" and can be produced by seamless manufacturing method following API 5L, EN and DNV standards. Pipes are inspected for internal and external defects using ultrasonic and electromagnetic inspection equipment. Pipes are automatically packed in bundles and tied with steel banding or wires in compliance with API loading and transportation standards.

ILJIN Steel produces hot-rolled and cold-drawn mechanical tubes made from alloy steel that meet or exceed various international standards including ASTM A519, ASTM A513, EN 10297, and EN 10305. ILJIN Steel has integrated process with seamless tube and cold drawing. ILJIN endeavors to provide better services to customers through quick delivery, technical improvement, value engineering, and prompt feedback for quality improvement.

ILJIN Steel is fully capable of producing drilling rods in both cold-drawn seamless and cold-drawn welded varieties. All raw materials used in producing drilling rods are sourced and made in Korea. Differentiating itself in the market, ILJIN Steel is a seamless mill that uses its own hollows for cold-drawn process. Our materials used in manufacturing drilling rods are pressure-resistant to 5,000 meters deep and deliver outstanding performance in the field.

ILJIN Steel manufactures a wide range of tubes for automotive applications. Pipes are available in sizes ranging from 0.5 to 7 inches and can be produced by the seamless manufacturing method in compliance with ASTM, JIS, EN and SAE standards. The pipe is inspected for internal and external defects using ultrasonic inspection and ECT equipment. The pipe can be packed as per the customer’s request.

Bright Annealed Stainless Steel tubes. B.A(Bright annealed) STS tubes are mainly used for super clean gas pipe line. And surface roughness, dimension tol erance and mechanical properties are controlled by cold drawing process. With high corrsive resistant properties ILJIN clean BA tubes are manufactured by specialty production process.

Precision Cold drawn shapes mean the product that has complicating geometry manugactured by drawing process under temperature. As this is made closely to the Final geometry, it is possible to minimize machining processing and to control the mechanical propertise and surface quality fitting to the use of customers. Accordingly, the effectiveness of cost cut down is increased more by reducing the material loss and processing time.

We learned that to climbers, even the weight of a half-emptied tube of toothpaste can make all the difference. We continuously seek out ways to reduce every last gram of weight without sacrificing strength.
