The old employees of the chemical plant know that many chemical materials will crystallize when the temperature is low. This is a headache for all chemical workers. What kind of pipeline should be adopted when our mortar pump is transporting high temperature and easy crystallized materials? When the device is installed, to ensure normal and stable operation for a long time?Liquid Ring Vacuum Pump Vacuum Adsorption?
1. Polyurethane direct burying insulation pipe without compensation Direct burial laying method: Uncompensated direct burial of polyurethane direct burial insulation pipe is to fix the pipeline by using the frictional resistance between soil and outer casing. It is no longer necessary to install a compensator, a fixing bracket, a pipe attachment sliding bracket, etc. on the pipe.Liquid Ring Vacuum Pump In Petrochemical Industry?
2, the pipeline insulation and heat traces are often seen, the pipeline anti-freeze insulation planning can not be ignored, especially in the cold chemical enterprises. Roots vacuum pump
The anti-freeze insulation planning requirements of the pipeline of the mortar pump are detailed in accordance with the medium temperature and process requirements. Otherwise, in the harsh weather conditions, the liquid pipe branch pipe is prone to cracking, so the pipe piping has its special requirements and cannot be planned according to common requirements.piston vacuum pump structure
At present, there is no systematically perfect equipment, pipeline anti-coagulation and anti-freezing guidelines in the domestic implementation of the planning norms. The requirements are combined with each pipeline and equipment on site, and the key planning methods for the anti-freeze insulation of the process pipeline and related precautions are taken to ensure the antifreeze. Insulation effect.Water ring vacuum pump?
3, polyurethane direct buried insulation pipe one-time compensation direct buried laying method: this method requires the use of compensator to compensate part of the total deformation of the section of the pipe under the planned temperature difference, so that the tightening, tensile stress is equal, the down pipe The effect of stretching or tightening the deformation stress. The one-time compensator is suitable for pipelines with working temperature ≤120°C and working pressure ≤1.6MPa, and its service life is more than 10 years.Rotary Vane Vacuum Pumps
