Classification of pipeline heaters

- Apr 16, 2019-

Pipe heaters are used in a wide range of subdivisions depending on the heating gas: nitrogen heaters and hydrogen heaters, which can be referred to as pipeline gas heaters. Water line heaters and tank heaters, which are also referred to as ducted liquid heaters.


1) Pipeline gas heater


A gas heater is an electric heating device that primarily heats a gas stream. The heating element of the gas heater is a stainless steel electric heating tube, and a plurality of baffles (baffles) are arranged in the inner cavity of the heater to guide the gas flow direction, prolong the residence time of the gas in the inner cavity, thereby heating the gas sufficiently to make the gas Uniform heating to improve heat exchange efficiency. The heating element of the air heater is a stainless steel heating tube which is filled with a heating wire in a seamless steel pipe, and the gap portion is filled with a magnesium oxide powder shrink tube having good thermal conductivity and insulation. When the current passes through the high temperature resistance wire, the generated heat is diffused to the surface of the heating tube by the crystalline magnesium oxide powder, and then transferred to the heated air to achieve the purpose of heating.


2) Pipeline liquid heater


The so-called liquid heater uses benzene acid as a heating agent heater, the wire reinforced refractory fiber layer, and the double-layer cladding layer which is tightly combined and distributed along the entire length of the resistance wire strand and its central resistance wire strand constitute a The monolithic type can be directly heated as needed, and can directly heat the monomer in close contact with the heated member, and the heating monomer is repeatedly formed around the shape and size of the heating object to form a strip shape, and then the plurality of parallel cells are separated by the metal wire. Wrapped together horizontally to form a braided high-temperature electric heater that can be directly wrapped around the object to be heated.
