Product Description

1 1 / 4 " CT80 API 5ST Continuous Coiled Tubing for Downhole Operation


Coiled tubing is a single length of up to thousands of meters, can be repeatedly bent, coiled on the drum for delivery of oil and gas pipe, and the traditional oil and gas pipe has a unique advantage of convenient transportation, high efficiency, widely used in acidification, fracturing, sand washing and other non-kill operations, known as the "universal pipe".


As coiled tubing manufacturer, our company specializes in providing high quality tubing of various specifications. We have rich delivery experience and strong production capacity. The maximum length of the single roll we can manufacture is 8000 meters, the maximum weight of the single roll is 30t(excluding the rolls), and the maximum outer diameter of the rolls is 3.40m. The outer diameter of the tubing ranges from 0.625 inches (15.88 mm) to 1.75 inches (44.45 mm) and the wall thickness ranges from 0.065 inches (1.65 mm) to 0.109 inches (2.77 mm). All dimensions and corresponding parameters comply to API standard, we can also customize it according to customers' requirement details.

Our coiled tubing has the following advantages:

High efficiency

Self-contained equipment without the support of rig (land).

Save operation time and cost without well-killing

The fluid can be pumped continuously when Lifting and lowering tubing

Reduce the possibility of formation contamination

Especially used for producing oil and gas Wells (no kill fluid entering the formation)

It can be used as a conveyer medium for tools in highly deviated and horizontal Wells.


Our conventional coiled tubing raw material has low content of sulfur and phosphorus, uniform microstructure, suitable mechanical properties, the flexion ratio of steel coil is lower than 0.80, and the strength performance difference of different parts is within 50MPa. All mechanical properties meet API Spec 5ST specification and have excellent fatigue resistance.


The steel grade and size information covered are as follows:

Type: Conventional coiled tubing(CT)

Advantages: high-strength, excellent fatigue resistance.

Reference material: CT70 CT80 CT90 CT110 CT110

Standard: API Spec 5ST

OD: 3/4 " ~ 3 1/2" (19.1 mm to 88.9 mm)

Thickness: 0.075 " ~ 0.3" (1.9mm~7.6mm)


Users can choose the required material and steel grade according to the operating conditions. The dimensions can be customized according to API Spec 5ST or user requirements.
