Product Description
The 1200mm hydraulic butt fusion welding machine is a heavy-duty semi-automatic welding equipment specially developed for large-diameter thermoplastic pipes and fittings, covering the welding range of 630–1200mm outer diameter. Adopting stable hydraulic drive design, it strictly complies with ISO 12176-1, DVS2207, ASTM F2620 international welding standards, realizing high-precision, leak-free and high-strength butt joints for HDPE, PP, PVDF plastic pipes and pipe fittings. Widely applied in municipal water supply, gas transmission, industrial sewage, mining and large-scale pipeline engineering projects, it guarantees welding joints with tensile strength equivalent to the parent pipe material.

Applications of 1200 mm Pipe Fittings Welding Equipment
1. Municipal Water Infrastructure
Large-diameter HDPE pipelines are commonly used in urban water distribution systems because of their corrosion resistance and long lifespan.
2. Gas Distribution Networks
The machine produces secure and leak-free joints essential for gas transportation projects.
3. Wastewater and Sewage Systems
HDPE pipes offer excellent chemical resistance, making them ideal for sewage treatment facilities.
4. Mining Operations
Mining companies use HDPE pipelines for slurry transport and dewatering systems where durability is critical.
5. Industrial Processing Plants
Chemical, pharmaceutical, and manufacturing industries rely on large-diameter plastic piping systems for fluid transportation.
FAQ
Q: What pipe sizes can a 1200mm hydraulic welding machine handle?
A: Standard models weld pipes from 630mm to 1200mm, with optional reducers for intermediate sizes like 710mm, 800mm, 900mm, and 1000mm.
Q: What materials can be welded?
A: HDPE, PP, PB, PVDF, and MPP pipes and fittings.
Q: What power supply is required?
A: Most machines require 380V / 50Hz, 3-phase power. A 30 kVA generator is recommended for field operations.
Q: How long does it take to weld a 1200mm pipe?
A: Total cycle time (facing + heating + fusion + cooling) typically ranges from 30–60 minutes depending on wall thickness and ambient conditions.
Q: Are these machines portable?
A: While heavy (2,600–3,000 kg), they are designed for transport to job sites and can be operated with a mobile generator.
Q: What is the typical lead time?
A: Standard lead time is 7–15 working days from order confirmation.
