How to avoid dead ends and blind corners of water purification equipment piping?

Purified water equipment piping is now popular in China is mostly SUS304 or 316, and requires the mouth of the fusion welding or special treatment. How to avoid dead ends and blind corners to do:

1, the use of automatic welding machine welding inert gas protection. Manual welding is easy to have bubbles small holes or melt spatter small holes, excessive welding is easy to penetrate, easy to cause intergranular corrosion.

2, pipe connection to have the lowest point of discharge. The slope should be 2-3% of the length of the pipe, and the lowest point of the pipe should have a discharge valve.

3, welding is completed to have the necessary passivation and cleaning and disinfection treatment.

4, the location of water intake to follow the 3D principle to avoid blind pipes as far as possible.

5, reasonable according to the flow rate to calculate the pipe diameter
