A 24-inch-diameter x 0.75-inch-wall X70 low-carbon bainitic-steel pipe was evaluated to obtain an independent measurement of pipe properties and to examine metallurgical characteristics that may affect behavior in gas-transmission service. The steel…
pipe produced from advanced high-strength pipe steels is being evaluated to provide information that will aid users in the selection of pipe for new gas transmission.
This report describes the fifth pipe evaluated, a 42-inch diameter x…
Steel producers have developed in recent years a number of new types of line pipe to meet demand for high strength pipe with superior low temperature toughness and good field weldability. Obtaining independent evaluation of these new products is the…
The demand for high-strength line pipe with good low temperature toughness has resulted in the development of a number of new types of line pipe for gas transmission service. Radically different steel compositions and highly advanced processing…
The objectives of this task are to obtain an independent measurement of pipe properties and to examine metallurgical characteristics that may affect the behavior of pipe in gas-transmission service. This report describes the results of the evaluation…
Over the years, there has been a continuing trend toward the use of higher strength steels in the manufacture of gas-transmission line pipe. In looking for ways to obtain higher strength pipe, there are, in general, two approaches that can be…
The objective of this project was to develop as software program to calculate the lifetime cost differential between pipelines designed for different combinations of steel grade and design factor. It is intended to evaluate the economic implications…
