API spec 5ST Conventional High - Strength Coiled Tubing CT70 Stainless Coil


Coiled tubing(CT), also known as flexible pipe, is a kind of welded steel pipe with high strength, good plasticity and strong corrosion resistance. The length of a reel can reach several thousand meters. At present, with the development of coiled tubing operation machine and related supporting equipment, coiled tubing operation technology has been applied to drilling, workover, oil testing, oil production, production increase, well completion and other fields.


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)
