Longitudinal Submerged Arc Welded Pipe (LSAW) is produced from high-quality steel plate. Through different forming processes, the pipe is welded with double-sided submerged arc welding (SAW), and then mechanical expansion to ensure accurate diameterspecifications and superior stability. LSAW pipes are widely used in oil & gas transmission, offshore engineering, structural applications, and large-diameter pressure pipelines.

With the vision of “United for a Shared Future, Building a New Ecosystem for High-Quality Industrial Development,” Tianjin Yuantai Derun Group remains committed to its original mission in the steel industry. The company continues to advance intelligent manufacturing, green production, and global expansion

Modern industry is built out of steel coils, which are the main component of many necessary products in various industries.

Yuantai Derun has awarded two distinguished certificates: the group ranked 326th among the “Top 500 Private Manufacturing Enterprises in China” and 491st among the “Top 500 Private Enterprises in China.”

Yuantai Derun has independently developed a new round-to-square forming line, marking a significant breakthrough in steel tube manufacturing. The upgraded technology has been developed to effectively overcome the cracking and deformation issues that often occur during the "round-to-square" bending process. This innovation ensures more stable shaping, improved precision, and enhanced product quality across large-size square and rectangular tubes.

Yuantai has achieved another breakthrough in JCOE pipe manufacturing.

The JCOE pipeline at our Tangshan base is equipped with advanced technology, ensuring enhanced efficiency, consistent quality and reliable performance.This article provides a look at the JCOE manufacturing process, detailing how Yuantai utilizes a sophisticated process involving forming, expanding, and testing to transform steel plates into high-quality welded pipes, setting a new standard in innovative steel pipe production.

In 2023, the Yuantai Derun-Tangshan production base commenced operations, boasting an annual capacity of 5 million tons.Zinc-Aluminium-Magnesium (ZAM) steel coils and ZAM steel pipes are the newly developed products, which represent a new generation of high -performance anti-corrosion materials.

The company has the most advanced domestic anti-corrosion steel pipe and spiral pipe manufacturing equipment, a first-class production team and efficient quality inspection and loading services.
