SUMMARY This report documents the analysis work done at Stress Engineering Services to establish the load capacity of all threaded flanges given in the October, 1989 Edition of API 6A (Sixteenth Edition) that violate the maximum bore requirement. A total of 12 threaded flanges...
Coverage This standard specifies the following requirements on rotary shouldered connections for use in petroleum and natural gas industries: dimensional requirements on threads and thread gauges, stipulations on gauging practice and gauge specifications, as well as instruments and...
Coverage-Threading and Gauging This specification covers dimensions, tolerances, and marking requirements for API threads and the gauges that control the acceptance criteria for the threads. Thread element gauges, instruments, and requirements for the inspection...
This specification covers dimensional requirements on threads and thread gages and stipulations on gaging practice, gage specifications and certification as well as the instruments and methods for the inspection of threads for line pipe, round-thread casing and tubing,...
I. INTRODUCTION The API Bulletin on Thread Compounds Composition (API Bul. 5A2) specifies a thread compound for casing, tubing and line pipe. This compound was developed by Mellon Institute, and was designed to provide lubrication during make-up (that is to prevent...
Information contained in this recommended practice is intended for use of pipe manufacturer inspectors, quality control personnel, field inspectors, threading unit operators, and users and purchasers of oil country tubular goods and line pipe. This publication was prepared under the auspices...
This document provides alternative connection assembly procedures to those found in API 5B (power turns) and those found in API 5C1 (optimum torque). The procedures set forth are referred to as "torque-position" because the make-up torque and final position are used as acceptance...
This technical report describes procedures for cold root rolling the thread roots on API 7-2 thread sizes using CNC Lathes (CW/CNC). Cold working can be applied by two methods: 1) cold rolling under pressure with a roller shaped like the thread form or 2) shot peening....
This Japanese Industrial Standard specifies the diameters of holes before threading ISO general purpose metric screw threads specified in JIS B 0205-2 by machining or before working similar to this (hereafter referred to as "hole size before threading").
1. SUMMARY 1.1 Project Background The work presented in this report is the third in a series of annual projects conducted by the Production Research Advisory Committee (PRAC) of the American Petroleum Institute to investigate the factors affecting leak resistance in API connectors. PRAC...
INTRODUCTION This report summarizes the results of a combined American Petroleum Institute (API)/Joint Industry Project (JIP) test program to investigate the performance capabilities of thread compounds for oil field casing and tubing that are being developed and marketed to meet...
1.0 SCOPE- The purpose of this test program is to evaluate the performance of a line pipe, casing and tubing (LP-C&T) thread compound. The tests are to be performed on full-size API tubing using API EU 8-round threads. The performance areas to be evaluated are...
This memo presents a mechanism that allows feeds publishers to express threaded discussions within the Atom Syndication Format.
This international standard lays down the essential dimensions of connection threading for sprayers for crop protection to cover existing and foreseeable needs.
1.0 INTRODUCTION 1.1 The API proposed TSA two step integral tubing connection for 2-7/8″ OD--6.50 ppf (.217″ wall) L-80 tubing was tested in accordance with API Recommended Practice 5C5, First Edition, January 1990, Class III. The product performed without leakage or failure to the...
Coverage This standard specifies the technical delivery conditions for steel pipes (casing, tubing, and pup joints), coupling stock, coupling material, and accessory material, and establishes requirements for three product specification levels (PSL-1, PSL-2, and PSL-3). The requirements for PSL-1...
This standard is intended to cover API ring-joint dimensions for American Standard (ASA)1 steel flanges, (threaded with API standard line pipe threads2 or American Standard thread), other sizes of flanges as required, and rolled, and slip-on welding and welding neck...
a. The purpose of this bulletin is to provide information on two types of thread compounds recommended for casing and tubing connections in high-pressure well service. This bulletin is for the convenience of purchasers and manufacturers in ordering and producing thread compounds and...
