The Charpy test':' provides a quick, inexpensive, and well-established measure of the fracture resistance of steels. There exists a mass of data on the relations between Charpy energy and metallurgical variables, but it is scattered. Furthermore, a…
A series of weldments were prepared in C/Mn and USIA steels by the submerged arc process. The weld metal microstructure was studied as a function of heat input/cooling rate and composition.
This report describes the development of a computer-based log interpretation system for the processing of multichannel pipeline survey records. Project goals and objectives are. included together with functional descriptions of system hardware and…
The thermal contractions of a cooling weld may easily produce average strains of several percent in the weldment. Since hydrogen, which is likely to be present, can embrittle the steel, it is not surprising to find that welds in steel often crack. In…
The use of an engineering critical assessment for analyzing defects in large diameter gas pipelines is presented. The assumptions and adaptations are necessary to allow the use of the British Standard PD6493 for pipeline girth welds are discussed.…
This document presents best practices guidelines for crankshaft protection to operators of slow-speed integral engine/compressors. The text first provides some background to the problem of crankshaft failure. It then summarizes the guidelines in a…
Addresses the time and temperature-dependent deflection characteristics of epoxy materials representing those widely used in reciprocating compressor foundations. Six epoxy material products from three different suppliers were tested, and include one…
These guidelines provide guidance to engineers responsible for installing or repamng the foundations of reciprocating compressors. If followed, the guidance should help assure an installation with a long life of trouble-free service. They address, in…
Evaluates various types of foundation chock materials for friction interaction with cast steel to help determine which chock materials are best suited for foundation applications.
