Petropedia explains Landing Nipple
The Landing Nipples are manufactured to accept the industry standard locking tools of major manufacturers. They exceed the performance of the tubing string. There are three basic kinds of Landing Nipples - selective Landing Nipples, no-go Landing Nipples and safety-valve or ported nipples. Each nipple is inspected with a coordinate measuring machine and tested with lock mandrel to ensure a trouble free lock setting. Any desired number of Landing Nipples can be fixed in the production string so that it offers an infinite number of positions for locking and setting surface controls. The following are the features of the Landing Nipple:
- It is composed of polished seal chamber.
- It is capable of reducing the mining and completion oil costs.
- It cannot develop a throttle function under the size and material of same oil tubes.
- It can be used for the standard oil tubes.
