Why Choose SRET: A Legacy of Engineering Excellence in ERW Tube Mill Manufacturing

A Legacy Since 1989

SRET was founded in Shenyang, Liaoning Province, China, in 1989 by five senior professors from Shenyang Ligong University, with the original mindset of becoming an industrial pioneer in China’s tube mill machinery manufacturing. It was among the first companies in China to specialize in this type of machinery.

Since then, SRET has remained an industry leader through continuous innovation and quality improvement. Today, SRET designs, engineers, manufactures, and supplies a full range of ERW tube mill machinery — from entry line and forming & sizing mills to welding machines, flying cut-off units, and end finishing machines — to meet a wide variety of application needs.

A History of Firsts in China’s Tube Mill Industry

SRET’s engineering journey includes a number of industry milestones in China:

• China’s first shear end welder
• China’s first horizontal spiral accumulator, and later China’s first extra-large horizontal spiral accumulator (660×20mm)
• China’s first CNC flying cutoff
• China’s first milling orbital cold saw cutoff, and later China’s first extra-large milling orbital cold saw cutoff (610×20mm)
• China’s first rectangular coordinate milling orbital cold saw cutoff

Full-Line Integration, Not Just Equipment

SRET offers both single equipment and total solutions for entire tube mill lines, with a professional team managing project integration to coordinate every element — ensuring delivery on time, to specification, and within budget. Production lines are supported by highly automated control systems along with tube-mill-tailored MES, covering every step from uncoiling to packaging, and providing transparency, productivity, cost management, and quality control.

A Track Record Backed by Real Numbers

According to SRET’s current company records:

• Equipment sold: over 1,000 sets
• Countries served: more than 40
• Customers served: over 500

Support Across the Full Equipment Lifecycle

SRET’s service framework covers three stages:

• Operation — start-up support, spare parts, on-site support, inspection, preventive maintenance, and repair
• Advancement — retrofit, refurbishment, extension, and electrical control upgrades for existing mill installations
• Enhancement— feasibility studies, training, engineering consulting, and performance studies to support decision-making

Conclusion

Choosing an ERW tube mill manufacturer is a long-term investment decision. SRET’s combination of engineering roots dating back to 1989, a track record of industry firsts, and full-lifecycle support is what has sustained its position in the industry for decades.
