The hydraulic quick coupler is an important connection component in the hydraulic system of a butt fusion welding machine. If the coupler becomes worn, damaged, or needs to be replaced during routine maintenance, the replacement process is actually very simple.

PE Pipe - Commonly Used Chinese Execution Standards (Current)

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?

Do not use electrofusion fittings in case of jetting, short circuit, or other similar abnormal conditions.

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.

Common hand-held fusion welders for PPR pipes include DN20-32, DN20-63 and DN75-110 models. For PPR pipes larger than DN160, butt fusion or electrofusion welding may be used.

A practical guide to HDPE butt fusion temperature, pressure, heating and cooling parameters. Learn why heater temperature alone is not enough, how interfacial pressure differs from hydraulic gauge pressure, and why DVS 2207-1, ISO 21307 and ASTM F2620/PPI procedures should not be mixed.

This article examines the key design requirements of a large-diameter PE pipe butt fusion machine, using the WP800A as a practical example. It covers frame rigidity, carriage guidance, clamping inserts, facing performance, heater temperature stability, hydraulic pressure control, equipment layout, site mobility and long-term maintenance.

Compare Welping A Pro, A Max, and FX butt fusion machine series to understand the differences in structure, hydraulic systems, and applications, and choose the right HDPE welding solution.

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.
