Flange heater
A flange heater is a heater that has a U-shaped design for the sheath heater and is equipped with a flange. It can secure a large electric capacity within the pressure range of tanks and pipes and the specifications of the flange. Like plug heaters, it has a structure that allows the effective heating element to be directly inserted into pipes through which liquids or other heated materials flow. In addition to JIS standards, flange specifications include JPI, API, ANSI, DIN, and NPC. There is a growing demand for heaters using a ferrule-type flange around manufacturing equipment for food, chemical plants, and flat panel displays.
