The VPWS 250 is an automatic HDPE butt fusion machine, German-designed and manufactured in the PRC. It is engineered for mobility and operational precision to produce reliable, high-integrity welds for a range of pipe diameters from 63mm to 250mm in diverse site environments.

The VPWS 250 integrates core welding functions into a user-friendly and robust framework. Its design, based on German engineering principles, prioritizes weld consistency, operational safety, and durability for demanding project requirements.

• Broad Material Versatility: Welds High-Density Polyethylene (HDPE), PE, PP, and PVDF pipes and fittings. This adaptability ensures the machine is a versatile asset for numerous applications in critical Water Infrastructure Solutions.
• Precision Thermal Control (DVS/ISO Compliant): An advanced PTFE-coated heating plate with electronic temperature regulation ensures consistent and uniform heat application. The non-stick surface and tight temperature deviation (<±5°C) are key to creating a homogenous weld zone that meets stringent international standards.
• Electrohydraulic System with Low Starting Pressure: The control unit features precise pressure regulation and a low starting pressure capability. This enables accurate force application even when welding small-diameter or thin-walled pipes, preventing structural distortion.
• Accurate Joint Preparation: The removable electric facing tool creates perfectly clean, parallel cuts. This precision is a critical step in achieving optimal fusion, maximum joint integrity, and preventing long-term leaks or failures.
• Integrated Process Management: An electronic countdown timer allows operators to accurately manage heating and cooling phases, eliminating guesswork and ensuring strict adherence to established welding cycle standards.
• Integrated Robust Frame: The machine’s basic frame is equipped with the hydraulic unit, planning tool, and heating plate, facilitating streamlined operation and consistent performance across all joints.

The VPWS 250 is designed for scenarios requiring both portability and precision. It is an effective solution for contractors and engineering firms working on critical pipeline projects where adherence to standards and long-term durability are paramount.

• Water Supply Systems: Creating durable, leak-proof joints in critical potable water distribution networks that demand certified performance and reliability.
• Wastewater and Drainage Projects: Suitable for robust materials like PP and PVDF, providing the structural integrity needed for long-term drainage and sewage solutions.
• Industrial Piping: Used for the precise installation of chemical-resistant and high-pressure pipelines in various demanding industrial facilities.
