CT110 API Flexible Stainless 5ST Alloy Steel Coiled Tubing

API Spec 5ST Conventional Stainless Coiled Tubing Flexible Tubing

Coiled tubing, also known as flexible tubing or CT, is a long continuous string of tubing spooled on a large reel. Normally it is made from low carbon alloy steel and ranges in diameter from 8 feet to 12feet. Coiled tubing can be straightened prior to being inserted into the wellbore and recoiled to spool back on the reel later.

The reason why CT is enjoying more popularity both home and abroad is that it has the following benefits:

e and high operating efficiency

Fewer personnel needed at the site

Easy to operate and save cost

Smaller environmental footprint

Constantly pumping fluids through when running and retrieving the coil

Our company is specialized in the production of coiled tubing of various materials and specifications, products in line with the industry's highest standards. Equipped with rich industry experience and mature production lines, our products are exquisite in workmanship and advanced in technology. Complete in size and specification, our tube can meet various operating conditions.

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:
