Selection Guide

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.

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.
