Handheld PE Plastic Pipe Welder

Product Overview

Unlike fixed welding machines, its compact design (weighing only 4.5kg) and battery-powered operation enable easy use in narrow spaces (e.g., underground trenches, building basements) or remote areas without access to grid power. Using hot melt extrusion technology, it melts PE material and the pipe ends simultaneously, creating a seamless, leak-proof connection with strength comparable to the parent pipe. The machine’s intuitive operation (with digital temperature display and simple controls) makes it suitable for both professional technicians and on-site workers with basic training.

Product Features

Heating System: Equipped with a high-efficiency ceramic heating element (500W power) that heats the welding nozzle to 200-230℃ (the optimal melting temperature for PE pipes) within 3 minutes. The heating element’s insulation design reduces heat loss, ensuring stable temperature output even in cold environments (as low as -10℃). The nozzle is made of copper alloy (with anti-oxidation coating) to prevent material adhesion and ensure smooth melt flow.

Extrusion Capacity: Manual feeding extruder (with a 500g material hopper) offering 1.5kg/h melt output, supporting pipe diameters from 20mm to 110mm (common sizes for residential and small-scale industrial projects). The extruder’s plunger-type design allows precise control of melt injection volume, ensuring sufficient material to fill the weld joint without excess overflow.

Portability: Weighs only 4.5kg (including battery) with an ergonomic rubber handle—reducing hand fatigue during prolonged use (e.g., 2-3 hours of continuous welding). The 12V lithium battery (10Ah capacity) supports 4 hours of continuous operation; a fast charger (included) can fully recharge the battery in 2 hours, enabling quick turnaround between work shifts.

Temperature Control: Features a digital LED display with ±5℃ temperature accuracy, allowing operators to monitor and adjust the welding temperature in real time (e.g., 210℃ for PE80 pipes and 220℃ for PE100 pipes). The machine also has automatic overheating protection—cutting off power when the nozzle temperature exceeds 260℃ to prevent material degradation and machine damage.

Applications

Water Supply Engineering: Ideal for welding PE water pipes in residential quarters, rural water supply projects, and garden irrigation systems. The welded joints have high pressure resistance (up to 1.6MPa) and excellent water tightness (passing 1-hour pressure testing at 1.5x rated pressure), ensuring no leakage even in long-term use.

Gas Pipeline Construction: Used for joining medium-density PE (MDPE) gas pipes in residential and commercial gas supply networks. The welding process meets GB 15558.2 standards, with the welded joints featuring a leak rate ≤1×10⁻⁷ Pa·m³/s—critical for ensuring gas safety. The machine’s compact size allows welding in confined spaces (e.g., under floors, inside walls) where large equipment cannot reach.

Drainage Systems: Suitable for on-site welding of PE drainage pipes in municipal engineering, building basements, and industrial wastewater treatment plants. The welded joints are resistant to corrosion from acidic or alkaline wastewater (pH 3-11) and can withstand underground soil pressure (up to 100kN/m²), ensuring long-term reliability in harsh environments.

FAQ

Q: What is the curing time for welded joints?

A: Curing time depends on pipe diameter and ambient temperature: for pipes ≤63mm diameter, curing time is 10-15 minutes at 25℃; for 63-110mm pipes, it takes 20-30 minutes. In low temperatures (≤10℃), curing time should be extended by 50% (e.g., 15-22 minutes for ≤63mm pipes) to ensure full bond formation.

Q: Can this machine weld other plastic pipes besides PE?

A: It is specialized for PE pipes (including PE80, PE100, and MDPE) due to their specific melting temperature range. For PP (polypropylene) pipes (melting temperature 220-240℃), optional high-temperature nozzles and heating elements are available—allowing the machine to weld PP pipes with minor modifications. However, it is not suitable for PVC pipes (which require solvent welding rather than hot melt extrusion).
