Product Description

API 5ST CT80 Coiled Steel Tubing For Oil And Gas Tubing Industry

 

Features:

  • Without thread connection, high work reliability and security

  • Quick move and installation, high working efficiency

  • No-stop working with large pressure-bearing capability

  • Less working area needed

  • Working cost is greatly reduced

 

Application:

Coiled tubing and its working equipments are called “universal working machine”, and can be divided into coiled string (including down well working string and velocity string) and coiled line pipe according to uses.

 

Down well work string mainly used in gas lift induced spray drainage, well flush and clean-up, blunt sand and plugging solving, wax removal, mud replacement, acidification, salvage, fracturing and totally more than 20 kinds of logging, work over, drilling and completion down well work.

 

Velocity string mainly used in drainage production increase of low permeability wells, also can replace tubing directly used as completion string.

 

Coiled line pipe mainly used in surface gathering pipe line on-land oil field and gathering pipe line on offshore drilling platform.

 

Standard: API 5ST

Coiled tubing includes downhole working tubing, and velocity tubing

Max. length: 8000m
