Flexible Ceramic Magnetic Preheater 30 V for PWHT
Magnetic Preheater 60 V is a pad heater constructed of interlocking sintered alumina ceramic beads which insulate stranded nickel-chrome wire. This durable construction forms a flexible mat of considerable mechanical strength. Magnetic Preheater 60 V can be used up to 2050 Deg F (1121 Deg C) and are supplied with insulated leads with male welder terminations.
Magnetic Preheater 60 V are designed for most preheat and post heat treatment (stress relieving) requirements on weld joined materials. Magnetic Preheater 60 V can be used to construct a simple, inexpensive furnace when combined with the proper insulation as well as in many other applications where a flexible heater is required.
Magnetic Preheater 60 V operate on low voltage (60 volts, 80 volts or less on AC or DC current) such as that supplied by a typical arc welder. Magnetic Preheater 60 V are designed for repeated heating applications. Their modular design permits a variety of element shapes, sizes, and thermal capacities to choose from. Magnetic Preheater 60 V can be used bare (as supplied) or with the application of rigid or flexible insulation to retain heat and speed up the heat treating jobs.
Post-weld heat treatment can improve the toughness and plasticity of laser welded joints markedly.
Preheating of materials to be welded where Magnetic Preheater 60 V can be used.
1). Pre-heating: Straight seam weld, longitudinal, circumferential weld, thick steel plate etc.
2). Post-welding heat treatment: tank, boiler or other metal jobs
3). Heating: mold heating, shipboard, zinc bath, large& irregular metal parts
4). Pipeline heating: pipeline oil, pipeline gas, pipeline water, pipeline petrochemical and other pipeline material
The using fields involved are petrochemical, oil and gas pipelines, aerospace, shipbuilding, steel, Hydropower construction ,tanks, boilers, vessels, pressure vessels, cylinders, metal structure, spatial structure, railway bridges, electricity water, mine construction, vehicle manufacturing, nuclear power, mining, plastics processing, energy saving process, screw barrel industries,ect.
