Compressor suction line issues
Thread Content
Here, the maximum pressure reached by the compressor is 150 kilograms. However, the pipes supplied by the compressor manufacturer are of type 14*2, size 321; it’s not clear whether they can withstand such high pressure, as in other applications, pipes capable of withstanding high pressures use a 14*3 configuration
It’s tolerable, no problem.
What does 14*2 mean?
Aren’t stress tests done? Just do it and you’ll know
There will definitely be no problems in the short term, but if considering the long term, it’s best to replace it – safety is at stake, so measures should be taken to ensure peace of mind. It also depends on the environmental corrosive gases. This post was last edited by zhaohh3211 on 2009-3-26 09:28.]
The wall thickness of 14*2 is 1 unit thinner than that of 14*3, resulting in a lower pressure-bearing capacity and a shorter service life. I agree with what was said on the 5th floor; it is the right choice to contact the manufacturer immediately and request a replacement.
Using 14*2 stainless steel tubes is fine.
It is best to use 14x3 tubes.
For safety, it is recommended to use 14x3 pipes.
Discuss with the compressor manufacturer regarding the replacement
It is best to use pipes with a higher pressure resistance; safety comes first
150 kilograms is equivalent to 15 MPa. As a general rule, the selection for pressure transfer pipes is as follows: below 6.3 MPa – Φ14x2; 6.3–16 MPa – Φ14x3; 16–32 MPa – Φ14x4
A 14x2 pipe can withstand a pressure of 15 Mpa, but it is approaching its limit; it is recommended not to use it instead opting for a 14x3 high-pressure pipe.
Refer to the standard HG-T 20512-2000: for instrument pressure lead pipes with a PN of 16.0 MPa or less, the diameter should be Φ14x3.
The manufacturer has made modifications, using 14`*4 pipes
