FlexiHeat XL Resistance Heating Blanket System

The FlexiHeat XL Resistance Heating Blanket System is a robust, flexible, and highly reliable solution for preheating pipe welds prior to and during the welding process. Utilizing durable heating pads or flexible blankets containing resistance wire elements, it provides conductive heat directly to the pipe surface. This system is renowned for its versatility, ability to conform to complex geometries (like heavy wall pipe intersections), and proven performance in demanding field conditions for pipelines of all diameters.

• Proven Reliability: Simple, robust resistance heating technology with a long track record in pipeline construction
• Superior Conformability: Flexible ceramic fiber or metal-mesh blankets can be tightly secured around pipes, fittings, valves, and complex weld joints
• Excellent Heat Retention: Blankets often include integrated insulation, improving thermal efficiency and protecting against wind and weather
• Modular & Scalable: Heating blankets can be connected in parallel to cover large areas or multiple zones, controlled by a single or multi-zone power unit
• Cost-Effective Solution: Lower initial capital cost compared to some advanced systems, with durable blankets offering long service life
• Comprehensive Kits: Available in complete kits including blankets, power/control units, thermocouples, and heat retention covers

Provides stable, controllable heat for sustained preheating periods required for thick-wall pipeline welding. Ensures code-compliant preheat and interpass temperatures (as per API 1104, ASME Section IX). High heating capacity suitable for challenging materials and high wall thicknesses. Durable construction withstands rough site handling.

• Preheat and interpass heating for mainline, tie-in, and repair welds on cross-country pipelines
• Heating for welding on pipeline fittings, elbows, reducers, and valves
• Applications requiring precise heat control on heavy-wall pipe (e.g., pump station piping, compressor station piping)
• Ideal for maintenance, repair, and overhaul (MRO) operations on existing pipelines
