Can stainless steel pipes be used in heat transfer oil systems? SS304
Thread Content
Because the company has many old pipelines – acquiring a factory. There are no new carbon steel pipes; for the heat transfer oil system, they used a rusted carbon steel pipe. I considered it unsuitable and requested that it be replaced, but the company had no carbon steel pipes available, and it was too late to purchase them – there were plenty of stainless steel pipes though. But it is usually made of carbon steel in terms of design, so it’s a dilemma. Due to the high-temperature strength of stainless steel. Actually, my system has a pump head of 40 meters.
Have someone calculate the strength; it should be fine, as the pressure in heat transfer oil furnaces is generally low
It can be used, but stainless steel welding rods must be used for welding.
Calculate based on the material properties to see if it’s possible
