Pipeline and Piping - Internal Coating Standards

Pipeline and Piping - Internal Coating Standards

Pipeline and Piping - Internal Coating Standards

(OP)
Does anyone know of a good, concise, standard for specifying the preparation of welds, type of welding for internally inaccessible locations, pipe access requirements, etc. which would be usefull to a field and/or shop contractor?  I'm not looking for a pipe coating application standard but for a pipe fabrication standard that would allow for a subsequent successfull interal coating application.

RE: Pipeline and Piping - Internal Coating Standards


arctic,

The AWS (American Welding Society) homepage (www.aws.org) will link you to their catalog section, where all of the specifications starting with "D10." relate to various pipe welding topics. The API (American Petroleum Institute) homepage (www.api.org) will link you to their catalog section, which includes RP5C6 "Welding Connections to Pipe", among others.

I hope some of these will get you to where you need to be, design-wise.

RE: Pipeline and Piping - Internal Coating Standards

I do not think you have do anything special welding wise for subsequent internal coating of the weld area.

In the oil and gas industry, we usually get the pipe from the mill with external and internal coating as applicable.  Then, internal coating is usually done by a speciality contractor.

For example, internal coating with FBE will require induction heat applied externally and an internal machine to spray the joint.
