On February 9, 2022, the automatic internal welding machine for pipelines in steep mountainous areas, developed independently by Company 1 of Langfang Pipeline Bureau, successfully carried out the first 6G-bit automatic welding in this industry, under the close attention of the staff.
Based on its projections regarding market prospects, Pipeline Company 1, leveraging its own technology center, submitted a project proposal to CNPC Engineering in 2019 titled “Research on Automatic Welding Equipment and Technologies for Pipelines in High-Slope Mountainous Areas.” This project involved the development and application of three types of equipment: beveling machines, internal welding machines, and construction vehicles. With the successful development of the internal welding machine, the development of the other two devices has also entered its final stage; it is expected that the entire set of equipment will be put into practical use on site in the second half of 2022.
The traveling system of the automatic internal welding machine for pipelines in steep mountainous areas adopts a dual-power mode of \"electric drive + pneumatic drive\", enabling automatic control for efficient operation with electric power on slopes and pneumatic power on flat sections； To address the issue of increased speed when going downhill, a single-cylinder multi-point brake disc brake is used to control the downhill speed, while the positioning arm makes use of a pneumatic mechanical lock cylinder to ensure accurate positioning of the internal welder on steep slopes.
