What does each digit on the barcode of an electrofusion fitting mean?

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.

This article records an internal technical discussion on roll grooving machines at Gruvmaster. Through open discussion and 3D model review, the team explored machine structures, design logic, and component relationships. The session focused on understanding not only how the machines operate, but why they are designed the way they are.

This article explains the role of HDPE butt fusion machines in pipeline engineering. It outlines the basic fusion principle, the function of butt fusion machines as process control equipment, and why butt fusion is widely used in medium- and large-diameter pipelines. The focus is on joint reliability, long-term system stability, and risk reduction in engineering applications.
