Section V-30406 - Maximum Operating Pressure [49 CFR 195.406]
Universal Citation: LA Admin Code V-30406
Current through Register Vol. 50, No. 9, September 20, 2024
A. Except for surge pressures and other variations from normal operations, no operator may operate a pipeline at a pressure that exceeds any of the following: [ 49 CFR 195.406(a)]
1. the internal design pressure of the pipe
determined in accordance with
§30161 However, for steel pipe in
pipelines being converted under §30111, if one or more factors of the design
formula (§30161) are unknown, one of the following pressures is to be used as
design pressure: [
49 CFR
195.406(a)(1)]
a. eighty percent of the first test pressure
that produces yield under section N 5.0 of appendix N of ASME/ANSI B31.8
(incorporated by reference, see §507), reduced by the appropriate factors in
§30161.A and E; or [
49 CFR
195.406(a)(1)(i)]
b. if the pipe is 12-3/4 in. (324 mm.) or
less outside diameter and is not tested to yield under this Paragraph, 200
p.s.i. (1379 kPa) gage; [
49 CFR
195.406(a)(1)(ii)
]
2. the design pressure
of any other component of the pipeline; [
49 CFR
195.406(a)(2)]
3. eighty percent of the test pressure for
any part of the pipeline which has been pressure tested under Chapter 303; [
49 CFR
195.406(a)(3)]
4. eighty percent of the factory test
pressure or of the prototype test pressure for any individually installed
component which is excepted from testing under §30305; [
49 CFR
195.406(a)(4)]
5. for pipelines under §30302. B.1 and B.2.a
that have not been pressure tested under Chapter 303 of this Subpart, 80
percent of the test pressure or highest operating pressure to which the
pipeline was subjected for four or more continuous hours that can be
demonstrated by recording charts or logs made at the time the test or
operations were conducted. [
49 CFR
195.406(a)(5)]
B. No operator may permit the pressure in a pipeline during surges or other variations from normal operations to exceed 110 percent of the operating pressure limit established under §30406. A Each operator must provide adequate controls and protective equipment to control the pressure within this limit. [ 49 CFR 195.406(b)]
