Quick Test Sub | Lubricator Pressure Testing

Home › Wireline Pressure Control Equipment › Quick Test Sub

Product Overview

The DEENPU quick test sub is designed to save rig time when pressure testing a lubricator rig-up before exposing it to well pressure. Every time the bottom connection is broken for a new wireline run, the full string must be re-tested — the quick test sub isolates the tested portion so only the joint(s) above it need testing on subsequent runs.

After the first full-string pressure test, the sub’s internal check seal lets you pressure test from the top and verify only the re-made connections, cutting test time on multi-run interventions dramatically.

Key Features

• Cuts pressure test time on every repeat wireline run
• Internal check isolates already-tested portion of string
• Full working pressure rating matching the lubricator
• Standard union / threaded end connections

Frequently Asked Questions

Q: Where in the string does it go?

A: Typically installed between the upper lubricator sections; joints above the sub are re-tested, the sub prevents pressure reaching the already-proven lower string.

Q: Does it work with any lubricator?

A: It works with any lubricator using matching union/thread end connections; specify your string configuration when ordering.
