In the construction of long-distance oil and gas pipelines, the selection of automatic welding equipment directly determines welding quality, construction efficiency and overall operational safety. Backed by mature automatic welding technologies and proven on-site implementation capabilities, Xionggu welding equipment has delivered outstanding performance once again in key national pipeline network projects.

According to the latest data from Xinjiang Petroleum Engineering Construction Corporation, as of May 22, the fully automatic welding team of Section 1 of the Jiangsu-Anhui-Henan Trunk Pipeline Project had completed a total of 625 weld joints. Only one joint required rework, achieving an impressive one-time welding pass rate of 99.9%. Xionggu extends its sincere congratulations on this remarkable quality outcome.

Project Overview

The General Contract Section 1 of the Binhai-Lushan segment of the Jiangsu-Anhui-Henan Trunk Pipeline is a flagship national infrastructure project for oil and gas facilities and a core component of China’s integrated national oil and gas pipeline network, carrying great strategic significance.

Key Construction Parameters:

Total pipeline length: Approximately 463 kilometers

Pipe diameter: 508 mm

Design pressure: 10 MPa (high-pressure oil and gas pipeline)

The project features harsh construction conditions, including complex terrain and limited working space in certain sections, posing considerable construction challenges. Stringent standards are also enforced for safety and quality management. Since the commencement of work, construction teams equipped with Xionggu automatic welding equipment have adhered to the principle ofSafety First, Quality Foremost. All construction procedures were implemented in strict accordance with standard specifications. The teams smoothly transitioned from initial trial welding to large-scale formal welding, ensuring steady progress of the project.
