Product Knowledge

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.

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.

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.

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.

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.

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.

This article introduces the standard remote control used on FX series butt fusion machines. Designed for real jobsite conditions, the remote control features a clear four-button layout, emergency stop function, trimmer control, and magnetic mounting. It allows operators to work more flexibly, safely, and efficiently during on-site pipe alignment and welding operations.

It allows operators to work more flexibly, safely, and efficiently during on-site pipe alignment and welding operations.

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.

This article explains how clamp configurations vary across FX series butt fusion machines based on pipe size. Models up to 315 typically use two to three clamp blocks, while machines sized 355 and above adopt a multi-segment full-circle clamp arrangement to provide more uniform contact and improved stability for larger and heavier pipes during alignment and welding.
