Copper tubes for steam tracing
Thread Content
Hello everyone, Happy National Day. At the construction site, several rotary valves with irregular shapes designed by our team require steam heating. The original design used 20-grade steel with a diameter of φ18×3mm, and each heating tube was 5 meters long; however, it was difficult to bend these pipes during installation. I now want to change it to copper tubes. May I ask what specification of copper tube should I choose and what should the wall thickness be? The steam is saturated steam at 0.8 MPa.
There should be relevant standards for this. But I searched for a long time; many products claim to be able to withstand a pressure of 4.0 MPa, such as those with dimensions of φ6×1, yet I couldn’t find any standards relating wall thickness to pressure resistance.
