What are the differences between API 5L and ASTM A106 api 5l x70 pipe failures

API 5L steel pipes are derived from API Spec 5L specification for line pipe,and they are suitable for the transportation of gas,oil and water.API 5L are divided into two product levels:API 5L PSL1 and API 5L PSL2.PSL1 is a standard quality for line pipe where PSL2 contains additional chemical,mechanical properties,and testing requirements.Grades covered by API 5L specification are A25,A,B and api 5l x70 pipe failuresThe master failure curve of pipe steels and crack paths in api 5l x70 pipe failuresHadj Meliani et al.

Introduction. There are four reported failures of a carbon steel pipe of a grade API 5L carrying natural gas. Consequential rupture of two natural gas pipes reported by Hassan and Iqbal was first (API 5L X56) caused by explosives blasting followed by a second failure (API 5L X60) by sandblasting effect. A similar type of pipe (API 5L X52) was failed by an action of a corrosive medium

Grade X70 - an overview | ScienceDirect Topics

For offshore pipelines, the current trend is toward line pipe in grade X70 with a wall thickness up to 40 mm. Fulfillment of the requirements for DWTT (drop-weight tear test) transition temperature is progressively difficult as the wall thickness increases. For wall thicknesses in excess of 30 mm, low transition temperatures can be achieved only by means of highly expensive rolling processes.Grade X70 - an overview | ScienceDirect TopicsFor offshore pipelines, the current trend is toward line pipe in grade X70 with a wall thickness up to 40 mm.
