Vacuum Insulated Pipe Cryogenic Equipment Cryogenic Process Engineering
Vacuum Insulation pipeline
Main Charateristics
The pipelines are made in sections, and connection by vacuum flanges or welding. Helium mass spectrometry is used to detect leakage of the inner and outer tubes, our pipelines with good cold insulation effect, convenient installation and maintenance, which can reduce installation jobs on site and save cost. Our pipelines adopts inner and outer compensation structure, with advanced technology, stable performance, safety and reliable.
