Materials:
Outer tube materials typically include In800, In840, 304, 316L, 310S, aluminum, copper, low-carbon steel, etc.
Magnesium oxide powder is selected according to different usage requirements, including high-temperature powder, medium-temperature powder, etc.
The resistance wire serves as the heating element, and there are generally two types of materials: Ni-Cr wire and Fe-Cr-Al.
Lead terminal materials generally include two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
Note: This heater can be directly mixed with SRY2 and SRY4 types.
Scope of Application for Tubular Heaters: Suitable for heating air, oil, water, chemical media, hot pressing molds, melting salts, alkalis, and low-melting-point alloys, etc. It features high thermal efficiency, long service life, high mechanical strength, easy installation, safety, and reliability.
Application:
SRY2 and SRY4 tubular electric heaters are used for heating oil in open or closed oil tanks. The SRY4 tubular electric heating element is used for heating flowing or circulating oil; therefore, this model has a higher surface load and is only suitable for use in oil with good heat transfer performance.
