Introduction to Graphite Tubes in Industrial Applications
Graphite tubes, also known as graphite pipes, are critical components in chemical, pharmaceutical, and energy industries due to their exceptional thermal conductivity, corrosion resistance, and structural stability. As a premier graphite tubes manufacturer in China, CFCCARBON LTD specializes in producing two distinct types of graphite tubing solutions: machined graphite tubes and extruded resin graphite tubes. This article focuses on our advanced resin graphite tubes designed for heat exchanger systems.
1. Two Types of Graphite Tubes: Machined vs. Extruded

-
Machined Graphite Tubes: Fabricated from high-purity molded, isostatic, or vibration-compacted graphite blocks, these tubes are precision-engineered for applications requiring tight tolerances.
-
Extruded Resin Graphite Tubes: Produced by blending premium resin binders with graphite powder and undergoing high-temperature graphitization, these tubes excel in heat exchangers with lengths up to 7,500mm—far exceeding standard machined tubes.

2. Why Choose Resin Graphite Tubes for Heat Exchangers?
Resin graphite tubes dominate heat exchanger applications for three key reasons:
-
Extended Length Capacity: With production lengths up to 7.5 meters, they reduce joint points and enhance system integrity.
-
Superior Pressure Resistance: Bursting pressure up to 6.8MPa ensures reliability in high-stress environments.
-
Impermeability Guarantee: Passes a 30-minute penetrability test under 1MPa pressure with zero leakage.
