Product Overview: Slotted Pipe
Slotted pipes are specialized tubular products designed for oil and gas wells, casing systems, and tubing applications. They are widely used in the installation of cased tunnels to facilitate the passage of utilities or obstacles without the need for open excavation. These pipes are manufactured from high-strength steel with a smooth wall and a minimum yield strength of 35,000 psi. To enhance durability, an anti-corrosion water-based coating is applied to the external surface, providing protection against atmospheric corrosion during transit and storage.

Key Features
Customizable slot dimensions, layouts, and geometries
More economical than wire-wrapped screens in many scenarios; often used interchangeably for sand control
Simplified installation process with no additional outer screen required
High resistance to collapse and deformation
Effective sand retention in wells with sand particles larger than 0.3 mm
Available in both longitudinal and vertical orientations with parallel or trapezoidal slot profiles, maximizing open flow area
User-friendly design with compatibility for connections to larger inner-diameter pipes
Typical Applications
Low-productivity wells where screen-based solutions are economically unfeasible
Sand management in reservoirs with low clay and fine content
Preferred sand control method in thermal recovery operations for heavy oil and bitumen
Suitable for environments with high concentrations of CO₂/H₂S, as well as SAGD, CSS, and CBM operations

Slot Variants
We offer laser-cut slots tailored to client specifications, available in two primary types:
Straight Slots
Perpendicular to the pipe wall, these slots maintain a consistent width from the inner to the outer surface. Although cost-effective to manufacture, straight slots offer relatively lower sand retention performance.
Keystone Slots
Featuring a tapered design, these slots are wider on the inner surface and narrower externally. This structure prevents particle clogging by allowing entered sand to flow through easily. While more costly, keystone slots significantly reduce the risk of production downtime due to slot blockage.
Slot Layouts
We support a wide range of slot configurations, including inline, staggered, gang, overlapping, horizontal, and other custom patterns. The most commonly requested layouts include:
Inline Pattern
Slots are uniformly arranged in aligned rings along the pipe length, creating continuous straight rows.
Single Staggered Pattern
Slots are grouped in evenly spaced bands around the pipe circumference, with adjacent bands offset from one another. This layout maintains structural integrity while ensuring uniform slot distribution.
Gang Pattern (Multiple Staggered Pattern)
Similar to the single staggered arrangement, but with pairs of slots positioned closely together at each location. This design offers superior torque resistance during installation and improved deformation resistance under thermal cycling, making it especially suitable for demanding applications such as SAGD.
