On July 15, the first 18-meter-long super-long spiral oil and gas transmission pipe for the **Gulang–Hekou Natural Gas Interconnection Pipeline Project** was successfully produced at CNPC Baoshishun (Qinhuangdao) Steel Pipe Co., Ltd. It is reported that this 18-meter-long spiral welded pipe is making its debut in the domestic oil and gas transmission pipeline sector.
It is understood that currently, the length of steel pipes commonly used in domestic oil and gas transmission pipelines is around 13 meters. During pipeline construction, using 18-meter-long steel pipes reduces the number of butt welds by 28% compared to 13-meter pipes. This not only **improves the safety of the transmission pipelines but also increases the construction efficiency by nearly 30%,** thereby reducing the cost of project construction.
