Together, they remain essential references for anyone engaged with piping.

It serves as a companion to ASME’s B31.1 Code on Power Piping as well as to the other codes in ASME’s B31 series. What is the asme code for pressure piping?ĪSME CODE FOR PRESSURE PIPING, B31 AN AMERICAN NATIONAL STANDARD B3 1.3-2002 A S M E PROCESS PIPING ASME CODE FOR PRESSURE PIPING, B31 ASME B31.3-2002 (Revision of ASME B31.3-1999) AN AM E R I CAN NATI O NAL STAN DAR D Date of Issuance: ApMandatory Date: OctoWhat is the b313 code for power piping?ī31.3 is one of ASME’s most requested codes. The purpose of this thread is to identify differences between B31.3 and B31.12 to help bring folks like myself up to speed on B31.12. Prior to this pipe spec, ASME B31.3 was generally the go-by for hydrogen piping systems in the US. Last year (2008), ASME B31.12 "Hydrogen Piping and Pipelines" was released. Whats the difference between asme b313 and b31 12? So, both the codes, ASME B31.4 and ASME B31.8 are pipeline design codes that cover the design, fabrication, installation, inspection, and testing of pipeline facilities.But, ASME B31.4 deals with pipelines transporting liquids and slurries whereas ASME B31.8 deals with gas transmission and distribution. This code joined other well-known ASME B31 Code for Pressure Piping sections such as B31.1, Power Piping and B31.3, Process Piping. Working under the guidelines of the American National Standards Institute, a new code, ASME B31.9, Building Services Piping, evolved and was published in 1982.

This incident prompted us to review our ageing pipelines to assess their technical condition at support locations in order to guarantee their safe & reliable operation. As pipelines continue in service for longer periods of time concern was raised that damage may go unnoticed or not reported and may result in catastrophic failure with consequences, such as loss of production, possible property or environmental damage and risk to the public.
These sections were subsequently cut out and replaced. It is also worth noting that eleven sections of pipe between these two jump overs were later found to have external wear and were below minimum allowable thickness (MAT), as per the design code ANSI/ASME B31.8. Subsequent investigation attributed the cause to wear of the pipeline against a transverse pipe support. In July 1998 a gas leak on a 12" GTL between two GDU Jump overs was observed. Our present focus is towards the localized external mechanical wear that is caused by thermal expansion and contraction of above ground GTL's at the pipeline supports. As of date two failures, one attributed to external corrosion and the other to external mechanical wear have been documented. From those two manifolds, the network provides gas for fuel and feedstock to all the major industries and power generating plants on the island of Bahrain through a Gas Distribution pipeline (GDL) network.Ī number of our GTL's have been in service for about 30 years with continuous addition and upgrading to the present time. ASME Code for Pressure Piping, 831 Supplement to ASME 831.8.
