2-7/8 API Standard Tubing

2-7/8 API Standard Tubing is a core OCTG (Oil Country Tubular Goods) product for medium and shallow oil and gas wells. Manufactured in strict accordance with API international standards, this tubing adopts high-quality alloy steel seamless forming process, with standardized outer diameter, wall thickness and thread connection dimensions.

It matches conventional downhole tools and wellbore structures perfectly, solving the problems of poor compatibility and unstable connection of non-standard tubing. With stable mechanical properties and reliable sealing performance, it is the preferred pipe material for conventional oil and gas field development projects.

Technical Specifications

Performance Characteristics

1.Stable Pressure and Mechanical Properties

The tubing design withstands internal pressure, axial loads, and downhole mechanical stresses during production operations. Controlled heat treatment processes improve strength consistency and help maintain structural integrity under long-term service conditions.

2.Reliable Threaded Connections

API-compliant thread sizes ensure proper connection with tubing accessories and completion equipment. Precise thread machining and inspection reduce the risk of leaks due to improper connections.

3.Wide Compatibility with Downhole Equipment

Standardized 2 7/8 inch tubing sizes are compatible with commonly used oilfield completion systems, reducing replacement difficulty and improving operational efficiency.

Quality Control Standard

All of our API standard tubing products implement full-process standardized quality control in accordance with API specifications. Raw materials are strictly screened, and each batch of pipes undergoes mechanical performance test, pressure resistance test, flaw detection inspection and thread precision detection.

Finished products are fully inspected one by one to ensure that size, performance and sealing indicators fully meet the standard requirements, and only qualified products can be delivered to ensure stable and reliable on-site use.

Application Fields

The tubing is widely applicable to various conventional oil and gas engineering scenarios. It is mainly used for medium and shallow oil and gas well production, downhole medium transportation, oil and gas well completion and reconstruction operations.

It also adapts to conventional water injection engineering, wellbore protection and auxiliary downhole operations in oilfields. Relying on API standard specifications, it can match various supporting downhole equipment and meet the pipeline laying demands of different oilfield working conditions.

Selection Guidelines

When selecting 2 7/8 inch API tubing, buyers should consider the following factors:

1. Well Depth

Deeper wells require higher strength tubing grades, such as N80, L80, or P110.

2. Corrosive Environment

For CO₂, H₂S, or corrosive environments, appropriate steel grades and corrosion protection measures should be selected.

3. Connection Requirements

EUE connections are typically used in applications requiring higher sealing performance, while NUE connections are suitable for general applications.

4. Production Conditions

The tubing selection should be matched to the fluid type, pressure, temperature, and production rate.
