Product Description

EAF/EAR landing nipple  

INTRODUCTION

The Top and Bottom No-Go Seating Nipples provide for the location of various wireline flow control devices in the production string. The nipple's no-go shoulder is used to help locate and set the Lock Mandrel, but, it is unloaded once the setting operation is completed.

The top no-go seating nipple is designed to accept only those top no-go type locks which carry the same letter designations as the seating nipple, either Model EAF, Model EHF, or Extreme depending upon the required pressure rating.

The bottom no-go seating nipple is designed to accept only those bottom no-go locks and accessories which carry the same letter designations as the seating nipple, either Model EAR, Model EHR, depending on the required pressure rating.

The location and number of seating nipples should be carefully considered in the completion planning stages to allow maximum versatility in the positioning of various flow control accessories.
