LSAW & SAW Welded Pipe Series

Our straight seam submerged arc welded pipes adopt mature welding and forming technologies, featuring solid structure, stable weld quality and reliable pressure resistance. We supply standard carbon steel pipes, large-diameter and thick-walled products, with various anti-corrosion treatments available to fit different usage environments. These products are widely used for fluid delivery, municipal engineering and general construction projects.

Oil & Gas and Chemical Pipeline Series

Specially developed for energy and chemical industries, our pipes comply with API 5L and other industry standards. With excellent low-temperature resistance, anti-crack performance and medium corrosion resistance, they are ideal for long-distance oil and gas transmission, offshore platforms, refineries and chemical production lines.

Structural and Piling Pipe Series

We provide structural and piling pipes that meet ASTM, EN, AS and other international standards. Made of high-strength steel and alloy materials, the products have great load-bearing capacity, impact resistance and deformation resistance. They are applicable to building foundations, bridges, wind farms, ports and offshore engineering, covering both above-ground structures and underground piling works. We also offer seamless structural pipes for projects requiring ultra-high safety performance.

Special Custom Pipe Series

We provide bimetallic composite pipes integrating high strength and strong corrosion resistance, which can work stably in severely corrosive working conditions. All customized products can be adjusted in material, size and processing technology according to personalized project demands.

Full Product Introduction

1. LSAW & SAW Welded Pipe

As our mainstream products, submerged arc welded pipes are manufactured via plate forming and automatic welding processes. The welds are smooth and uniform with few internal defects, ensuring overall structural stability. We offer complete specifications including conventional carbon steel pipes, large-diameter pipes and thick-walled pipes. Customers can choose hot-dip galvanizing, 3PE coating and epoxy coating for surface anti-corrosion treatment to adapt to humid, buried and outdoor environments. The pipes have balanced performance and high cost performance, serving as the common choice for water delivery, gas supply, factory piping and general infrastructure construction.

2. Oil & Gas and Chemical Pipeline

Tailored for energy and chemical industries, this series strictly follows international industrial standards. Optimized formulas and post-weld heat treatment greatly improve low-temperature toughness and pressure resistance. The pipes can withstand the erosion of oil, natural gas, steam and various chemical media, and operate safely in extreme environments such as deserts, cold regions and ocean areas. They are widely used for cross-regional long-distance energy transmission, supporting pipelines of offshore facilities and process pipelines of refineries and chemical plants.

3. Structural and Piling Pipe

Our structural and piling pipes cover multiple international certification standards to meet the construction requirements of different countries and regions. Adopting high-strength carbon steel and low-alloy steel, the products feature high tensile strength and outstanding anti-fatigue performance.

Products under international standards conform to ASTM, EN and Australian specifications, which are specially designed for overseas construction, underground piling and large steel structure projects. General structural pipes are suitable for high-rise buildings, bridge supports, port facilities and wind power projects. Offshore dedicated pipes have enhanced seawater corrosion resistance and structural stability for marine platform construction.

In addition, seamless structural pipes are available. Without welding seams, they have excellent overall integrity and are used for key components that require the highest safety and load-bearing performance.

4. Special Custom Pipe

Bimetallic composite pipes adopt composite manufacturing technology. The outer layer guarantees mechanical strength and impact resistance, while the inner layer provides excellent anti-corrosion ability, solving the usage problem of pipelines in strong chemical corrosion environments.

We support full-range customized services for all products. We can adjust outer diameter, wall thickness, length, material grade and pipe end processing according to project drawings and working conditions. Professional technical teams will follow up the whole process from scheme design to finished product delivery to ensure the products fully match the actual project demands.
