Hydraulic and automatic roll grooving machines are both used for steel pipe grooving, but they suit different working needs. Hydraulic machines are more flexible for job sites, installation work, and medium-volume processing, while automatic machines are better for workshops, batch production, and higher efficiency. This article compares their key differences and helps users choose the right machine based on pipe size, workload, working environment, and production needs.

Choosing the right roll grooving machine depends on more than the maximum pipe size. Pipe diameter, wall thickness, material type, job site conditions, production volume, and application all affect the final selection. This article explains how to choose a suitable roll grooving machine for different projects, from small and medium-size pipe installation to large-diameter pipe grooving, workshop prefabrication, pipe fitting grooving, and high-accuracy groove cutting applications.

Bell-mouth is a common pipe-end deformation problem in roll grooving, especially on thin-wall or larger diameter pipes. This article explains why it happens, including pipe support, pressure control, roller matching, and pipe-end preparation, and shares practical ways to reduce deformation and improve groove consistency in daily steel pipe grooving work.

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.

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.

OGS and AGS are two key grooving standards used in pipe connections. While OGS is widely applied in standard pipe sizes, AGS is designed for large-diameter applications where higher joint stability is required. This article explains their differences, selection logic, and compatible equipment, helping users better understand how to choose the right grooving standard.

Pipe vises play an important role in stabilizing pipes during threading, cutting, and grooving operations. Without proper support, pipes can shift or vibrate, reducing efficiency and accuracy. Two common structures are used in pipe processing: tri-stand pipe vises for flexible job site work and bench pipe vises for stable workshop environments. VH401 and VH402 represent these two practical solutions.

Roll grooving has become the mainstream connection method in fire protection systems due to its fast installation, fire-free safety, easy maintenance, cost efficiency, and strong seismic performance. It is widely accepted by major international standards.
