Description

Technical Parameters

Introduction

API 5CT oil tubing is a specialized steel pipe manufactured according to the API 5CT standard established by the American Petroleum Institute (API). It is primarily used to transport crude oil and natural gas from formations to the surface.

Advantages

High-Strength Structure
API 5CT oil tubing is manufactured from heat-treated, high-quality alloy steel with a yield strength of ≥ 552 MPa. It maintains structural stability in high-pressure, high-stress downhole environments, effectively preventing fracture or collapse.

Tight Dimensional Tolerances
API 5CT tubing is manufactured using high-precision automatic rolling equipment, maintaining dimensional deviations within ±0.5%, ensuring a precise fit with fittings and casing.

Corrosion Resistance
The tubing surface undergoes a phosphating treatment, forming a dense phosphate protective film that isolates the metal from direct contact with corrosive media, ensuring a service life of over 10 years in corrosive media such as hydrogen sulfide and carbon dioxide.
