Operation Guide

A simple step-by-step guide to adjusting hydraulic pressure on A and A Pro butt fusion machine hydraulic units before operation.

A PE butt fusion welding machine is used to butt-join pipes directly; it is not for dragging pipes. For example, I welded 50 meters at Location 1 and 50 meters at Location 2. I want to connect the pipes from the two locations together. How can I do it?

PE pipes cannot be directly heat-fused to PPR or iron pipes. Depending on pipe size and service conditions, use brass-insert transition fittings, threaded adapters, flange connections, push-in connectors, steel-plastic transitions, or clamp couplings.

Connecting PE reducing couplings in series increases cumulative risk at the joints. If series connection cannot be avoided, use compliant fittings, follow PE butt fusion or electrofusion procedures, and pressure-test the entire piping system.

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.

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

A pipe stand with an integrated scale improves batch grooving efficiency by turning manual positioning into reference-based setup. Operators can quickly repeat the same settings for identical pipe sizes, reducing adjustment time and workflow interruptions. This simple feature enhances consistency, supports multi-operator environments, and is particularly valuable in continuous or repetitive grooving operations.
