Carbon Steel Coiled Tubing - CT55 to CT130

Product Introduction

Microalloyed Coiled Tubing is a kind of steel tubing withhigh strength and good plastic, which is developed byhigh strength low alloy steel (HSLA) and high frequencywelding (HFW) technology. Single tubing is continuouslymilled on production line and wrapped onto a spool as acertain length for delivery, the length per reel can reach8000 meters.

Features and Usage

Microalloyed Coiled Tubing having excellent low cyclefatigue properties is an indispensable tool for oil and gaswell maintenance and stimulation. and also is the mostcommon and most-popular used coiled tubing producurrently.
