Recently, the special submerged arc welding wire steel for pipeline steel developed by BTGT Steel Pipe Technology Corporation came out, and it has been applied to the West-East Gas Pipeline, Sino-Russian East Line and other projects. BTGT has also become the fourth company that can produce X80 pipelines after SHBG, BJGT and JSSG. A steel company specializing in submerged arc welding wire steel for steel.
The special submerged arc welding wire steel successfully developed and produced by BTGT solves the problem of matching with the self-produced BT80 high-grade large-diameter pipeline steel. The welding seam technical indicators meet the requirements, and it has been successfully applied to natural gas pipeline projects such as the West-East Gas Pipeline. , Up to now, more than 1,200 tons have been supplied in batches.
The annual output of BT65 to BT80 series pipeline steel products is more than 100,000 tons, but BT80 high-steel grade large-diameter pipeline steel has not been matched with special submerged arc welding wire steel.
Since 2020, BTGT has independently designed BT80 large-diameter pipeline steel special submerged arc welding wire steel alloy composition system. The product has been evaluated by JXBJ Petroleum Steel Pipe Technology Corporation welding test, and all performance indicators fully meet the relevant technical conditions. Subsequent applications will be applied to pipeline steels above BT65.
