Whenever I plan something for myself, especially for the pleasure of me, there is must be something will make it fail, and that's happen to me. I have to go to Head Office at the Karawang, to follow the ISO training and that really not a good time for training, but as the order from the Bos, so I have to obey it. While I hate that situation, I think I better to post this Piping & fabrication blog, at least that will make me a little bit cooling down, I think.


The Pipe Fabrication Institute (PFI) publishes advisory Engineering Standards (ES) and Technical Bulletins (TB) intended to serve the needs of the pipe-fabricating industry at the design level and in actual shop operations. The PFI standards contain minimum requirements; however, the designer or fabricator may consider specifying additional requirements beyond the scope of PFI publications. The use of PFI standards or bulletins is voluntary. A complete listing of PFI publications follows:
