The New Edition of ANSI B31.3—Some Significant Changes
(The American Society of Mechanical Engineers (ASME), 1978)The new edition of ANSI B31.3 retains established code rules for most petroleum refinery piping with little change. However, significant additions have been made to cover 1) safe handling of ... -
Shear Fracture Propagation by DCB Testing
(The American Society of Mechanical Engineers (ASME), 1978)A shear fracture propagation in steel was investigated with the aid of spring-loaded DCB testing, that was developed as a laboratory simulation test of shear fracture propagation in pressurized ... -
Acoustic Emission Examination

Fracture Discontinuities and Structural Analysis in Resource Recovery Endeavors
(The American Society of Mechanical Engineers (ASME), 1978)The need for redirection of investigative effort in the area of mineral and energy recovery is emphasized: more fundamental analytical descriptions must be linked to innovative design explorations ... -
Shallow Formation Hydrofracture Mapping Experiment
(The American Society of Mechanical Engineers (ASME), 1978)Geophysical diagnostic techniques are being developed to characterize the massive hydraulic fractures that are being utilized for the enhanced gas recovery from the Western tight gas reservoirs. ... -
Embedded Elliptical Crack at a Corner
(The American Society of Mechanical Engineers (ASME), 1978)A procedure for estimating the stress intensity factor of an embedded elliptical crack near the corner in a region of high stress concentration such as pressurized or thermally shocked ... -
On the Gasdynamics of Running Ductile Fracture in a Pressurized Line Pipe
(The American Society of Mechanical Engineers (ASME), 1978)Developments in the modeling of the gasdynamics associated with running ductile fracture in pressurised line pipe are reviewed and critically examined. It is argued that existing models of gas ... -
Nonshrinking Heat and Acid-Resistant Hydrothermal Cements for Use in Oil and Gas Wells
(The American Society of Mechanical Engineers (ASME), 1978)Novel hydrothermal cements have been developed for use in the recovery of energy sources from hot and deep wells ranging in temperatures from 150°F to over 1000°F. -
Use of Explosives to Enhance Power of a New Design of Pile Hammer
(The American Society of Mechanical Engineers (ASME), 1978)The purpose of this paper is to describe the adaptation of conventional concepts of internal ballistics to the driving of piles. Special considerations are given to the differentiation between ... -
Dynamic Analysis as an Aid to the Design of Marine Risers
(The American Society of Mechanical Engineers (ASME), 1978)This paper describes a computer program for economically predicting the dynamic response of marine risers to lateral forces from waves (regular and random) and currents (vortex shedding). Present ... -
Pressure Losses Inside Tool Joints Can Alter Drilling Hydraulics
(The American Society of Mechanical Engineers (ASME), 1978)Pressure losses associated with small-throated (internal upset) tool joints have been measured. Computations show that these losses may contribute significantly to the overall loss in a mud ... -
Propagating Buckle Arrestors for Offshore Pipelines
(The American Society of Mechanical Engineers (ASME), 1978)When an underwater pipeline is buckled in the presence of sufficient external pressure, a propagating buckle is initiated, and the buckle front will propagate along the pipeline until a region ... -
Vibratory Power Delivery to Rock During Rotary-Vibratory Drilling
(The American Society of Mechanical Engineers (ASME), 1978)This paper outlines the theoretical description of the vibratory portion of the rotary-vibratory drilling process. A multiple mechanical element model is used to describe the drill string and ... -
Pressurized Cylindrical Shell With a Rigid Circular Inclusion
(The American Society of Mechanical Engineers (ASME), 1978)The effect of a rigid circular inclusion on stresses in a cylindrical shell subjected to internal pressure has been studied. The two linear shallow shell equations governing the behavior of a ... -
