RG-2T is designed for inward and outward groove forming on metal pipes. This article explains how a convex groove is formed by controlled rolling pressure during the outward groove forming process.

This article explains how to choose a 1200mm butt fusion welding machine for large PE and HDPE pipe projects. It covers key factors such as working range, frame stability, pipe clamping, facer performance, heating plate uniformity, hydraulic control, and long-term manufacturer support.

The RG-2X roll grooving machine is designed for 2"–12" steel pipes, focusing on stable operation and practical usability. With support for SCH40 pipes up to 10 mm thickness and a fully sealed hydraulic system, it is suitable for fire protection, construction, and general piping applications. The machine provides a reliable solution for medium to large diameter pipe grooving.

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 straps and pipe hangers serve different roles in piping systems.

Pipe straps are designed for direct surface fixing in light-duty applications, while pipe hangers provide stronger, adjustable support for suspended and heavier piping systems.

Selecting the right option depends mainly on installation method and load requirements.

Which welding machine is suitable?

This article provides a practical overview of common pipe support solutions, including pipe straps, hangers, and riser clamps. It explains their typical structures, applications, and key differences. By understanding how each type is used in different installation conditions, users can make more informed choices to ensure stability, safety, and long-term performance in piping systems.

What should I do if the hydraulic butt welding machine fails to hold pressure?

What are the consequences of incorrect phase sequence connection for 380V three-phase power supply?

With the 380V hydraulic power unit, the milling cutter begins to move when the forward/reverse valve is actuated.

A custom 2000mm butt fusion machine was developed by Welping for large-diameter pipeline applications. The design focuses on structural stability, consistent pressure control, and uniform heating performance under demanding conditions. Rather than a standard product, the machine reflects a project-based approach, addressing the practical challenges of ultra-large pipe welding.

Step-by-step guide to hydraulic pressure adjustment on A PRO butt fusion machine, ensuring stable operation and correct setup before welding.

CM-12 and CM-20 are two electric hydraulic pipe cutters designed for different pipe sizes and working environments. While both machines use the same cold-cutting principle and hydraulic feeding system, CM-12 focuses on efficient cutting of small to medium pipes in workshops, whereas CM-20 is built for larger pipes and job-site conditions requiring stronger support and mobility.

Jerky movement of a butt fusion machine may be caused by air trapped in the hydraulic hose. This guide explains the cause and shows how to remove air from the hydraulic system step by step.
