Product Description

Junk Sub

Description: 
Junk Sub (Fishing Cup) is normally used to catch and remove junks that are too heavy to be circulated preventing them from settling at the bottom of the well-bore. Typical junks are shivers and fallen objects such as carbide tooth, drill bit and bearings which are too heavy to be removed from the well- hole through conventional fluid circulation. Junk Sub's main function is to keep well bottom clean to increase bit service life, reduce and prevent drill bit from unexpected damage.

Features:
1. Designed and manufactured according to API spec 7-1.
2. The Junk cup can clean sundries at the bottom of the well.
3. It can improve the service life of drill bit.
4. It operators can get quicker, cleaner scraping jobs.
