We demonstrate strong industrial adaptability and customization flexibility in the production capability and product layout. Our digital production workshop with strict control over every technical step from raw materials to finished products ensures stable performance under heavy-duty working conditions. Our product range covers pipe diameters from 1" to 32", including standard pipes and irregular fittings. The portfolio provides suitable support for different operating requirements with portable tools, heavy-duty hydraulic machines, and fully automatic systems.

Beyond standard product supply, we also provide OEM and ODM services. We can develop customized grooving and fabrication solutions based on specific working conditions and technical requirements, covering the full process from design and development to manufacturing. To ensure full lifecycle support, we have built a service system that covers both pre-sales consultation and after-sales support. At the project planning stage, our technical team evaluates pipe materials and working conditions to provide equipment selection recommendations and performance matching suggestions. After delivery, we offer operation guidance, maintenance support, fast spare parts supply, and guarantee consistent on-site performance with reliable long-term operation.

Meet Our Chief Engineer, Mr. Arron

Behind our product development is Mr. Arron, our chief engineer and the person behind many of our core mechanical designs. His work has directly shaped the structure and direction of the current product range. He has been involved in the design and development of more than 200 mechanical tools and systems, with a strong focus on roll grooving equipment. Over the years, he has also led several OEM and ODM collaborations with international partners.

Mr. Arron focuses mainly on improving hydraulic system design. One of his recent developments is a fully sealed integrated hydraulic pump that brings the oil circuit into a more compact and efficient structure. It is paired with the OnePush™ quick feed system and TitanSeal™ sealing design, which supports longer operating cycles with reduced maintenance needs. His design approach is practical and field-oriented. It is based on real equipment usage and feedback from different working conditions, with the goal of making the pipe fabrication system easier to operate and more durable in daily use.
