What are the requirements for installation, commissioning and operation of pharmaceutical purified water equipment? Figure 1.
Jingderui purified water equipment 1.
The installation of the process pipeline should try to use the ceiling to pass through the water inlet point, and it is not suitable to pass through the ground to prevent the process water from being stagnant in the pipeline and forming stagnant water
.
Note that the circulation loop should not be installed too low, and the water inlet pipeline should not be installed too low, so as to avoid two-way pollution
.
The design and installation of the pipeline should avoid dead corners and blind pipes.
The pipeline installed horizontally should form a suitable inclination angle, and the pipeline should have a certain inclination angle in order to discharge the stored water
.
The length of the dead angle at the point-mounted valve should not be greater than 3 times the inner diameter of the branch pipe, and the terminal water outlet generally adopts a circulating pipeline
.
2.
Select the diaphragm valve with reliable quality and the pipeline with polished inner surface, and passivation treatment
.
Ensure that the flow velocity in the water outlet pipe should be greater than 2m/s
.
3.
The storage tanks, pipe fittings and pipes for process water should be made of non-toxic and corrosion-resistant materials
.
Storage tanks and pipelines are mostly made of 304 or 316L stainless steel
.
Sanitary pipeline connection method is adopted, and the pipeline and pipeline should be passivated to better protect the equipment
.
The valves on the main pipe and branch pipe on the pipeline should be made of stainless steel diaphragm material
.
4.
The pipeline is connected by automatic argon arc welding, and the installation of the pipeline must ensure that all the water in the pipe can be drained
.
The slope is generally specified as 1% of the length of the pipe.
If there is accumulated water in the pipe, a drainage point or valve must be set up, and the number of drainage points should be minimized
