Products Description
The SKC-MA400 Multi-Angle Insulated Pipe Butt Fusion Welding Machine is a high-precision workshop solution designed for manufacturing custom plastic pipe fittings, specifically optimized for insulated pipe systems. It supports the production of elbows at any angle, equal tees, equal crosses, and 45°/60° Y-type fittings, and is capable of welding PE, PP, and PVDF pipes. With dedicated configurations, it seamlessly handles corrugated insulated pipes and pre-insulated district heating pipes, fully complying with ISO, DVS, and relevant national welding standards.
Insulated pipe systems rely on leak-tight, structurally sound joints to maintain thermal efficiency and prevent energy loss. The SKC-MA400 ensures synchronous fusion of inner carrier pipes and outer insulation casings, eliminating common issues like insulation damage, joint leakage, and weak welds that often occur with traditional methods. This makes it the ideal equipment for prefabricating fittings for district heating, chilled water, and industrial thermal transfer applications.
Key Features
Precision Hydraulic Drive System The hydraulic power unit delivers stable, adjustable welding pressure, ensuring uniform force distribution across the fusion interface. The advanced buffer design guarantees smooth, shock-free operation, which is critical for consistent joint strength in thick-walled and insulated pipes.
Ergonomic Multi-Angle Operation The heating plate and facing tool feature a manual flip mechanism with gas spring assistance, reducing operator fatigue and enabling quick setup for different fitting angles. This flexibility makes it ideal for producing elbows, tees, and other complex geometries.
Independent Digital Temperature Control A dedicated digital controller maintains welding temperatures within ±5°C, preventing under-welding (cold joints) or over-welding (material degradation) that can compromise joint integrity. This precision is especially vital for multi-layer insulated pipe welding.
Dual-Adjustable Alignment Worktable The two-layer worktable is fully adjustable forward/backward to ensure perfect pipe alignment, minimizing eccentricity and improving the coaxiality and sealing performance of finished joints.
Optional Data Logging System Upgrade with a color touchscreen and USB interface to monitor, record, and export key welding parameters (temperature, pressure, time) for full quality traceability.
Automation-Ready Design Integrate optional displacement sensors to automate the entire welding cycle, reducing human error and boosting production efficiency for high-volume fitting prefabrication.
High-Reliability International Components Critical control elements use top-tier international parts, ensuring long-term, stable performance even in continuous workshop environments, minimizing maintenance downtime.
Optional Accessories
45°/60° Y-Type Fitting Kit: Steel elbow clamps and multi-layer steel liners for welding DN90–400mm Y-shaped fittings.
Independent Control Box: Includes color touchscreen for full welding process monitoring and data recording.
Hydraulically Operated Facing Tool & Heating Plate: Automated tool actuation for hands-free operation.
Full Automation Program: From facing to welding completion, with optional integration with the data logging system.
Hydraulic Elbow Clamp Lock: Enhanced stability for elbow welding.
Hydraulic Tee/Cross Clamp Lock: Optimized clamping for complex three-way and four-way fittings.
