Finned Tubular Heater Elements
Tubular heaters can be formed into virtually any shape, brazed or welded to any metal surface, and cast into metals. The tubular heater's basic construction consists of a computer-designed helical coil of 80% Nickel 20% Chromium alloy resistance wire fusion welded to the nickel-coated steel terminal cold pins.
- Wide selection of sheath material... copper, steel, 304 stainless steel, 316 stainless steel, Monel 400, Inconel 600 and titanium. Consult factory.
- St. steel fins with st. steel sheath for non brazed construction.
- Ceramic to metal end seals.
- Lead wires, plate terminals with screws, threaded studs, spade terminals.
- Bulkhead fittings, mounting brackets, flanges. .315 Dia. sheath also available.
Type MF --Mounting Bracket
The 16 gauge Stainless Steel Mounting bracket is an economical way to mount the heater in non-pressurized, non liquid applications. Unless otherwise specified the bracket will be located 1/2" (13 mm) from the edge of the heater sheath. Custom brackets of any size, thickness and material can also be supplied to meet your requirements.
Type B --Watertight Bulkhead Fittings
Bulkhead fittings provide a leak-proof method for mounting tubular heating elements through tank walls. A gasket, plated steel washer and brass hex jam nuts are included. Specify if a stainless steel washer and jam nut are required when ordering stainless steel fittings.
Standard mounting location is the threaded end of the bulkhead flush with the end of the element sheath. For other mounting locations specify distance from end of sheath to gasket surface on bulkhead.
Fittings are silver brazed or TIG welded to the element, depending on fitting material and customer application.
Fittings in table are the most commonly used. Special fittings can be manufactured to meet your requirements.
Specify: material, flange type, thread type and length.
