A Hydraulic Testing Procedure for Polypropylene Pipes Wall Rupture

Safety in Technosphere, 2020
Polypropylene pipes have a significant drawback – high values of the heat-stretch factor. Material properties are changing as the temperature rises, and material is exposed to increased pressure in the pipeline. In such a case, operation of polypropylene pipes is becoming unsafe.

Evaluation of Blast Loads From Pipe Ruptures

Volume 4: Fluid-Structure Interaction, 2017
High-pressure pipeline ruptures are a credible explosion hazard at many industrial facilities. The blast field generated by a pipe rupture is highly directional. However, there have been few evaluations of the directional blast loads produced by pipe ruptures.

Classification of ruptures of gas pipes according to length

Strength of Materials, 1995
On the basis of an analysis of the kinetics of rupture and data on breakdown of gas pipes the article suggests a classification of ruptures. This makes it possible to classify each special case of rupture either as local-type or as global avalanche-type rupture.

Predicting the creep rupture life of polyethylene pipe

Polymer Engineering & Science, 1979
AbstractA number of techniques have been developed in the past for the prediction of the dependence of the creep rupture life of polyethylene pipe on applied stress and temperature. It is now proposed that, using a modified form of the activated rate procss equation in which the activation volume varies predictably with temperature, a generalized ...

Furan Flare Piping Rupture Analysis

CORROSION 1997, 1997
Abstract A 12 inch (305mm) diameter FRP piping section containing Furan resin disintegrated after four years of service in a vapor relief system. External inspection of the flare stack conducted just three months earlier revealed no obvious problems.

Predicting Pipe Rupture Frequencies Using xLPR

Volume 1: Codes and Standards, 2020
Abstract Over the last several years, the U.S. Nuclear Regulatory Commission (NRC), in cooperation with the Electric Power Research Institute (EPRI), conducted a multi-year project that focused on the development of a viable method and approach to address the effects of primary water stress corrosion cracking (PWSCC) in primary piping ...

The effects of reactor coolant system pipe rupture motion on tributary piping and attached equipment

Nuclear Engineering and Design, 1980
Abstract This paper presents a rigorous analysis of a pressurized water reactor coolant system (RCS) to determine time-history excitations of intact equipment and tributary piping attached to the RCS caused by a postulated guillotine rupture in the primary coolant piping.

Vessel Steam Pipe Rupture Force on Internals

Volume 4: Fluid-Structure Interaction, 2008
A postulated steam pipe rupture in a water-moderated nuclear power plant would cause a sonic discharge from the rupture and the formation of a large-amplitude step decompression, which would travel through the pipe to the reactor vessel. When the decompression arrived at the reactor, it would propagate into the vessel where it would exert decompression

Rupture Hardware Minimization in Pressurized Water Reactor Piping

Journal of Pressure Vessel Technology, 1989
Abstract For much of the high-energy piping in light water reactor systems, fracture mechanics calculations can be used to assure pipe failure resistance, thus allowing the elimination of excessive rupture restraint hardware both inside and outside containment.

Investigation of Titanium Pipe Rupture in a Chemical Production Reactor

CORROSION 2004, 2004
Abstract A severe catastrophic rupture failure occurred in a spool pipe made of titanium (ASTM B337 grade 2) in an oxidation reactor of the Purified Terephthalic Acid (PTA) production plant. The titanium spool pipe was connected directly to the hot air inlet nozzle of the oxidation reactor - operated at 215 °C and 365.5 psi in a hot air ...
