 N RP 5A4

Annotation

FOREWORD

a. This recommended practice is under the jurisdiction of the API Committee on Standardization of Tubular Goods

NOTE No provision of this recommended practice shall be cause for rejection of casing or tubing provided the threads are in accordance with the requirements of API Std 5B

b. The purpose of this publication is to provide information on the transporting, handing and installing of reinforced thermosetting resin casing and tubing in oilfield usage

c. Trouble-free service and maximum safety should result if this Recommended Practice is followed RTR casing and tubing differs in properties from metallic tubular goods and different installation techniques are required

NOTE These recommendations are applicable to normal situations but exceptional conditions may warrant different practices It is not intended that these practices conflict with any regulatory code

d. It IS suggested that the selection of a thread compound be given careful consideration by the user, bearing in mind that a satisfactory compound should possess certain properties, the major of which are (1) to lubricate the thread surfaces to facilitate joint make-up and breakout without galling, and (2) to seal voids between the mating.thread surfaces and effectively prevent leakage Compounds which have given outstanding service for RTR casing and tubing are "Teflon" base and "Teflon" — molybdenum disulfide base thread compounds
