To meet the downstream user’s demand for high strength external upset tubing and expand market share of high added value product, Angang seamless steel pipe mill developed the potential of equipment and has developed a successful forming p110101.6 mm EUE tubing.
At present the product has a production of 1100 tons, and get the user's widely praise.
Under the situation of the world's energy demand continues to grow, as a major energy producers of oil mining challenge the deep oil and gas wells and high corrosion of oil and gas wells which are difficult to extract. The deeper the oil well is, the higher the oil companies require for the tubing thread strength.
Last November, a user to Angang proposes p110101.6 mm EUE tubing requirements, the product as API non-standard specifications, high value-added products.
Used in deep well mining of oil and gas pipeline in high strength thread index demand is higher, external upset processing is carried out on pipe head.
Angang seamless steel pipe of the original two EUE tubing are secondary molding, there exists a tin thickness, appearance is not smooth, the cost is higher, cannot satisfy the needs of customers.
In order to improve the grade of products, expand market share, high added value products the factory mining potential external upset existing production line equipment, carry out product development research.
Project team operation technical personnel on the basis of many years of production, from the grinding tool design, heating system and three aspects of equipment and then built bottleneck problem of new products, successfully developed 40 hits a molding 101.6 mm EUE tubing, qualified rate reached 100%.
At present, the product has been formed a large-scale production, and to receive additional orders.
