miters in pipeline

Does API 1104 allow any miters on a pipeline and if so, what are the specs.

Re: miters in pipeline
I have done a porject for Libya ,in that project had lot of 46" Mitre bends and we have followed the API 1104 only.

Re: miters in pipeline
Your question is incorrect. API 1104 is not a pipeline design code or specification its intent is the control of welding and associated inspection accept/reject criteria.

You need to refer to the pipeline design specification such as B31.4, B31.8, DNV FS 101 or similar. Even if the specification permits the use of miter bends you then need to investigate the long term effects these will have on your ability to perform other actions on your pipeline such as pigging.

  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field
