API 5CT J55 Casing and Tubing – High-Quality Solutions for Oil & Gas Applications
 

Introduction

 
OASIS is a trusted supplier and wholesaler of API 5CT J55 seamless and ERW casing and tubing, providing reliable and cost-effective solutions for the global oil and gas industry. Our products are manufactured to meet strict API standards, ensuring superior performance in shallow well applications and low-stress environments.
 
 

What is API 5CT J55?

 
API 5CT J55 is a grade of seamless or electric-welded (ERW/EFW) steel pipe specifically designed for casing and tubing operations. With a minimum yield strength of 379 MPa and tensile strength of 517 MPa, J55 offers a balanced combination of strength and ductility, making it ideal for shallow oil and gas wells where wellbore support and fluid circulation are critical.
 
 

 
 
 
Key Features

• Material Grades: J55 (seamless and ERW/EFW)
• Yield Strength: ≥ 379 MPa
• Tensile Strength: ≥ 517 MPa
• Diameter Range:

                                     Casing: 114.3 mm – 508.0 mm (4.5″ – 20″)
                                     Tubing: 26.67 mm – 114.30 mm (1.05″ – 4.5″)

• End Types: Plain end, buttress thread, short/long round thread
• Color Coding: Bright green band for identification

Chemical Composition

• Phosphorus (P): ≤ 0.030%
• Sulfur (S): ≤ 0.030%

 
    J55 is designed for environments where extreme corrosion resistance is not required, allowing for efficient performance in standard well conditions.

Flattening tests are mandatory for electric-welded pipes to ensure structural integrity.
 
 

Manufacturing Process

• Seamless or electric welding (ERW/EFW)
• Weld seams are heat-treated to eliminate untempered martensite
• Straightening is not required for J55 grade
• Couplings and related accessories are manufactured using seamless processes

Quality Assurance

 
All J55 products undergo rigorous nondestructive testing (NDT), including visual inspection and wall thickness verification, to ensure compliance with API 5CT standards.
