    Technical Knowledge | What Does “T” Mean in a Roll Grooving Dimension Table?Sep 2,2026
    What does “T” mean in a roll grooving dimension table? This article explains T as the minimum allowable pipe wall thickness and uses a 1" pipe example to show how it relates to SCH 5S, SCH 10, and SCH 40. It also explains why standard roll sets do not cover every wall thickness and when special roll sets may be required.

    Technical Knowledge | OGS vs. AGS Grooves: A Side-by-Side Comparison from Our Recent Grooving TestJul 27,2026
    OGS and AGS are two different grooved piping connection systems designed for different applications. Through a real grooving test, this article compares the differences between OGS and AGS groove profiles, explains why AGS is preferred for large-diameter piping, and shows how compatible roll grooving machines can switch between different groove systems by using dedicated roller sets.
  • Technical Knowledge | Integrated vs. Split Hydraulic Systems: What Really Affects Maintenance and Oil Life?
    Technical Knowledge | Integrated vs. Split Hydraulic Systems: What Really Affects Maintenance and Oil Life?Apr 29,2026
    Split hydraulic systems use a sealed pump design to prevent air and dust from entering the oil circuit, reducing contamination. Compared with traditional integrated systems, they can extend oil change intervals to 1–2 years, lower maintenance frequency, and improve long-term operating stability. The CM series applies this design consistently across different size models.
  • Technical Knowledge | Pipe Straps vs. Pipe Hangers: What’s the Difference?
    Technical Knowledge | Pipe Straps vs. Pipe Hangers: What’s the Difference?Apr 27,2026
    Pipe straps and pipe hangers serve different support roles in piping systems. Straps are used for surface fixing in light-duty applications, offering simple and cost-effective installation. Hangers suspend pipes for heavier loads, providing greater flexibility and support. Choosing between them depends on load requirements, installation method, and application conditions.
