OREANDA-NEWS. August 28, 2012. Baosteel successfully supplied corrosion resistant longitudinal antacid tubes in batch to CNPC, Kazakhstan north Troyes oil gas pipeline project under the circumstance of lack of three hot metal removal resources, and unfeasibility of traditional process production paths. It insists on the idea of “simple, speed, cost” and rapidly meeting the needs of customers with many departments cooperation and mining production line potential to figure out ways to the logistics and technological process, reported the press-centre of Baosteel.

A few days ago, the first batch of 1700 tons of products had “taken” the special train to foreign country for “service” and met the engineering need, which gained the good reputation by the customers for Baosteel good product quality and delivery date.

North Troyes engineering is the oil gas composite of Kazakhstan, Aktobe state with 2.2 billion tons of geological reserves. The weather feature in Aktobe State has great effect for the duration of pipe laying. To ensure the work period, CNPC had the strict demands on the delivery date of the contract. After comparing with different steel enterprises comprehensively, Baosteel welded tube finally replaced seamless tube and successfully received the contract of 7500tons of corrosion resistant antacid tube with excellent product quality and good delivery time.

According to Baosteel UOE manufacture routine process, it is from continuous plate slab steelmaking plant in Baosteel to rolling in the Plate Department, then to UOE tube making. With its small caliber, wall thickness, and strict corrosion resistant antacid properties, this kind of product needs three removal of molten iron. As lack of three removal of molten iron resources, and producing according to the traditional route, plate is difficult to roll, with low efficiency, high cost on plate shape and uniformity control. Baosteel manufacture department thought comprehensively to integrate different resources in directly under plants and departments. Finally, they developed a rapid, high efficiency, low cost process path under the circumstance of unaffecting other contracts.

During the implementation of the process, each plant and department achieved many breakthroughs with a further promotion on manufacture capability under the leadership of Baosteel manufacture department. Steelmaking plant in Luojing District achieved to smelt low-phosphorous low-sulfur pipeline steel slab in batch for the first time; Hot rolling mill supplied the coils to UOE for the first time; Heavy plate department firstly implemented full open plate inspection to hot rolled coil open flat plate; UOE made pipe with hot rolled coil open flat plate for the first time, which was also the first single small-caliber anti-sulfur tube.

The successful supply for goods not only satisfied the customers’ needs but also further combed the manufacture process and mined potential of each resources, exerted the advantage each production line so as to supply new ideas and methods for subsequent other work.
