Steel pipe knowledge

Steel performance depends on more than chemical composition alone.

In manufacturing processes, we expose steel to deformation and heat treatment under a wide range of conditions. How the material reacts during these steps strongly affects its final material properties.

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.

Is galvanized steel pipe safe for drinking water？Galvanized steel pipes were widely used in water supply.But now something new materials are better than galvanized steel pips.

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

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.

Tianjin Yuantai Derun: 20+ years in square tube production. Two modern bases in Tianjin & Tangshan, annual capacity >1 million tons, globally top-ranked.

Durable rolled and welded steel pipes for construction, structural, and industrial use. Available in custom diameters, thicknesses & lengths. Strong welds, corrosion-resistant.

Square rectangular tube have become one of the core materials of photovoltaic support structure due to their high quality mechanical properties, flexible size adaptation and weld connection methods.

Hot-dip galvanizing and cold-dip galvanizing are both methods of applying zinc to steel to prevent corrosion, but they vary greatly in process, durability, and cost.

The processing of welded steel pipes is a multi-step, multi-process manufacturing process involving key links such as material selection, forming, welding, heat treatment, and finishing.
