Full-Set Seamless Tube Rolling Tools Shipped Worldwide

Recently, our company completed mass delivery of full-set core tooling and spare parts for hot rolling seamless tube mills, including various specifications of guide shoe plugs, plug rods, mandrel bars, roller assemblies and supporting hot centering machines. These products have been shipped to multiple large domestic seamless pipe manufacturers and oil & gas pipe production bases in Central Asia, winning wide recognition from global clients for our domestic high-performance wear-resistant tube rolling spare parts.

The seamless steel pipe industry is accelerating its transformation toward high-end production, low operational costs and long-cycle stable manufacturing. Traditional imported rolling dies feature long procurement lead times, high maintenance costs, and vulnerability to wear & cracking under high-temperature working conditions, which hinder continuous efficient operation of PQF continuous rolling mills and cross piercing mills. To address these industry pain points, our technical team has dedicated decades to research on hot rolling deformation mechanisms, optimizing material formulas and structural designs for the full line of core rolling spare parts based on massive on-site production data.

1. Performance Upgrade of Wear-resistant Piercing Tooling (Guide Shoe Plugs Series)

Our series of guide shoes and piercing plugs adopt composite high-temperature wear-resistant alloy casting technology with optimized streamlined profiles. The upgraded structure effectively reduces friction between tube blanks and tooling during piercing, extending service life by over 35% compared with conventional castings, lowering customers’ frequent replacement downtime and overall production costs.

2. High-temperature Piercing Plug Rod & Mandrel Bar

Our plug rods and mandrel bars are forged with special heat-resistant alloy steel and processed with precise surface strengthening treatment. They maintain stable dimensional accuracy under long-duration high-temperature rolling, greatly improving the wall thickness uniformity of finished seamless pipes, perfectly matching high-speed continuous rolling production lines.

3. Customized Roller Assembly & Hot Centering Machine

We supply complete roller assemblies tailored to different piercing and continuous rolling units. Our self-developed hot centering machines serve as essential auxiliary equipment for pipe blank pre-processing, ensuring accurate centering before piercing to eliminate eccentric defects of finished tubes.

Our full portfolio covers all core consumables and equipment for seamless tube hot rolling lines, covering guide shoe plugs, plug rods, mandrel bars, roller assemblies and hot centering machines. We provide one-stop customized solutions for oil casing, pipeline steel, boiler tube and mechanical pipe manufacturers.

Moving forward, our R&D team will keep upgrading alloy material formulas and processing craftsmanship, offering more durable, cost-effective localized rolling tooling alternatives to replace imported products, and expanding cooperation with steel pipe enterprises across Russia, Central Asia, the Middle East and Southeast Asia.
