E-mail:sales@highboomingpipe.com2 7/8 J55 EUE oil tubing
A commonly used to grade for most wells when it meets the design criteria. Some operators recommend it be full-length normalized or normalized and tempered after upsetting when used in carbon dioxide or sour service (ring-worm corrosion problems); however, such heat treatments increase costs. J55 has been the standard grade for tubing in most relatively shallow(<9 000ft) and low pressure (<4 000psi) wells on land.
