Chapter 8 General Welding Rules of ASME B31.3 and API 570 8.1 Introduction This chapter is to introduce you to the main general welding rules contained in API 570 and ASME B31.3.API 570 is for in-service inspection of process piping and therefore most welding carried out will be repair welds,rather than welds carried out on new systems.Much of API 570 is also concerned with the repair of opogcTubing Size Nominal Weight Grade Wall Thick- N n ess in.Inside Dia.in.Threaded Coupling Col- lapse Resis- tance psi Internal Yield Pres- B sure Joint Yield Strength Capacity Table T C Non Upset lb/ft T C Upset Drift Dia.Coupling Outside Dia.Nom.OD on-Upset in.Upset R g.in.Upset Spec.in.T C Non-U s e t lb T C et lb arrels per differences between N-80 and L-80 Casing PipeAPI 5CT L80 petroleum casing pipe is the lifeline to preserve the operation of the oil well.The geological conditions are various in addition to the underground dynamics are complicated and disorderly.Pipes undergo be dictated under numerous forces,such as tensile
Note Multiwalled carbon nanotubes have the highest tensile strength of any material yet measured,with labs producing them at a tensile strength of 63 GPa,still well below their theoretical limit of 300 GPa.Tubing grade guidelines - Production TechnologyDec 21,2017 API Tubular Yield Tensile Strength#0183;API tubing steel grades are identified by letters and numbers which dictate various characteristics of the steel.For each grade,the number designates the minimum yield strength.Thus L-80 grade steel has a minimum yield strength of 80,000 psi.In other words,it can support a stress of 80,000 psi with an elongation of less than 0.5%.Tubing Specifications - Production TechnologyOct 18,2017 API Tubular Yield Tensile Strength#0183;API tubing grades correspond to casing grades with the exception that P grade tubing has a tensile strength of 105,000 psi and is referred to as P105.Tubing comes with non-upset (NUE) and external upset (EUE) ends.EUE tubing is more common,because of the benefit that cutting threads into the tubing ends does not reduce the body strength.
